OBJECTIVE:Spontaneous isolated celiac artery dissection (SICAD) is a rare condition with an unclear natural history and no management consensus. This study evaluated mid-to-long-term outcomes of conservatively managed SICAD. METHODS:This single-center, retrospective cohort study identified patients with SICAD from January 2011-December 2022 in the institutional electronic health record. Demographics, comorbidities, radiographic features, management, and outcomes were reviewed. Clinical endpoints were symptomatic remission, significant organ malperfusion, rupture, and secondary intervention. Radiographic endpoints included dissection remodeling (i.e., shortened dissection length or increased true lumen diameter), celiac aneurysm incidence, and aneurysm diameter growth among <1.5 cm, 1.5-1.9 cm, and ≥2.0 cm size categories. Endpoints were stratified by symptomatic vs. incidental presentation. RESULTS:Forty-nine patients with SICAD were identified. Eighty percent were male, and 57% had hypertension. Extra-celiac aneurysms were present in 25%, including 12% with aortic aneurysms. Forty-nine percent of SICADs were symptomatic on presentation, while 51% were incidentally discovered. Patients with incidental SICAD were older than symptomatic patients (62 ± 15 years vs. 54 ± 8 years, p=0.02) but had similar comorbidities. Ninety-two percent of symptomatic patients experienced complete symptom resolution without operative intervention by the earliest follow-up (182 ± 386 days). No incidental cases developed symptoms over a mean of 3.9 ± 3.5 years. No significant organ malperfusion, rupture, or secondary intervention occurred in this series. Symptomatic SICAD was more likely to undergo remodeling than incidental SICAD (p=0.02) over an average of 3.3 ± 3.7 years. Thirty-two percent of symptomatic cases had partial remodeling, and 37% had no residual dissection. Seventy-one percent of incidental dissections remained stable without remodeling. Celiac thrombus on initial imaging predicted remodeling (p=0.003). Baseline antihypertensive (p=0.006) and antiplatelet use (p=0.047) were associated with remodeling in symptomatic patients only. Aneurysmal degeneration was noted in 46% of all presenting lesions; none were ≥2.0 cm in maximal diameter. Incidental cases presented with more aneurysmal dilatation than symptomatic cases (59% vs. 32%, p<0.001). No celiac aneurysms at presentation grew over an average of 4.8 ± 4.0 years. Forty percent and 13% of incidental and symptomatic cases without initial celiac aneurysms, respectively, developed incident aneurysms by a mean follow-up of 2.0 ± 3.0 years (p=0.3). CONCLUSIONS:Conservative management of uncomplicated SICAD yielded excellent clinical outcomes, even with incomplete remodeling and aneurysmal degeneration, which were common, albeit largely benign. Patients may warrant screening for aneurysms beyond the celiac axis. Antihypertensive and antiplatelet therapy for ≥3-6 months may promote remodeling until dissection stabilization.

Fenestrated Endovascular Aortic Aneurysm Repair Is Associated with Increased Sac Regression on Postoperative Volumetric Analysis Compared to Endovascular Aortic Aneurysm Repair
Zhang, Jason; Teter, Katherine; Ramkhelawon, Bhama; Cayne, Neal; Garg, Karan; Rockman, Caron; Ferreira, Luis; Ferrer, Miguel; Li, Chong; Jacobowitz, Glenn; Maldonado, Thomas
BACKGROUND:Endovascular aortic aneurysm repair (EVAR) is utilized to treat abdominal aortic aneurysms, while patients with short infrarenal necks can undergo fenestrated EVAR (FEVAR). Previous studies have demonstrated decreased aortic neck dilation for FEVAR compared to EVAR. Sac regression is a marker of success after EVAR; however, little is known regarding changes in sac volumetrics. This study compares aortic sac regression after EVAR versus FEVAR using volumetric analysis. METHODS:A retrospective review of prospectively collected data from 120 patients who underwent EVAR was performed. Thirty patients underwent FEVAR (Cook Medical Inc, Bloomington, IN) and 90 patients underwent EVAR (30 each with Endurant [Medtronic, Dublin, Ireland], Excluder [Gore, Flagstaff, AZ], and Zenith [Cook]). Demographic data were analyzed. Using 3-dimensional reconstruction software, preoperative and postoperative aneurysm sac volumes were measured, in addition to aneurysm characteristics. RESULTS:, P = 0.005). EVAR patients had greater number of lumbar arteries (7.26 ± 1.68 vs. 5.31 ± 1.93, P < 0.000001). On postoperative follow-up, FEVAR cases had greater sac regression compared to standard EVAR (-22.75 ± 25.7% vs. -5.98 ± 19.66%, P = 0.00031). The percentage of sac regression was greater when measured by volume compared to maximum diameter for FEVAR (-22.75 ± 25.7% vs. -13.90 ± 15.4%, P = 0.01) but not EVAR (-5.98 ± 19.7% vs. -4.51 ± 15.2%, P = 0.246). Those in the top tertile of percent volume of thrombus (>48.5%) were more likely to experience greater than 10% sac regression by volume (55% vs. 33.3%, P = 0.015). On multivariate analysis, FEVAR was associated with sac regression greater than 10% by volume (odds ratio [OR] 4.325, 95% confidence interval [CI] 1.346-13.901, P = 0.014), while endoleak (OR 0.162, 95% CI 0.055-0.479, P < 0.001) and 2 patent hypogastric arteries (OR 0.066, 95% CI 0.005-0.904, P = 0.042) were predictive against. CONCLUSIONS:Fenestrated EVAR is associated with greater sac regression compared to EVAR on volumetric analysis. This difference may be attributable to decreased endotension within the aneurysm resulting from less aortic neck dilatation, while the greater proportion of thrombus may be a protective factor from growth. Patients being evaluated for EVAR with borderline neck anatomy should be considered for FEVAR given increased sac regression.

Natural History of Asymptomatic Mesenteric Artery Occlusive Disease and Predictors of Symptomatic Progression
Harish, Keerthi B; Chervonski, Ethan; Rokosh, Rae; Garg, Karan; Berland, Todd L; Sadek, Mikel; Teter, Katherine A; Rockman, Caron B; Jacobowitz, Glenn R; Maldonado, Thomas S
OBJECTIVE:The objective of this study was to characterize the natural history of incidentally identified asymptomatic mesenteric artery stenosis and to identify clinical and radiographic predictors that differentiate patients with asymptomatic mesenteric artery occlusive disease (MAOD) and patients with symptomatic chronic mesenteric ischemia (CMI) diagnosed at index study. METHODS:This single-institution retrospective analysis included patients diagnosed with >70% stenosis of the celiac or superior mesenteric artery (SMA) on axial imaging or duplex ultrasound in an institutional radiology database. Patients were grouped into asymptomatic MAOD and symptomatic CMI cohorts according to their clinical presentation at index study. The primary endpoint was progression of disease from asymptomatic stenosis to CMI. Demographic, clinical, and imaging features at index study were also compared between asymptomatic and symptomatic cohorts. RESULTS:79 patients met the inclusion criteria, with 43 in the asymptomatic group and 36 in the symptomatic group. Patients in the asymptomatic group were followed for mean 32.7 ± 30.2 months; 60.5% (n=26) were referred to and followed by a vascular surgeon for 21.5 ± 27.8 months. No asymptomatic patients developed symptoms during the follow-up period. All patients in the symptomatic group were evaluated by a vascular surgeon and underwent procedural intervention for CMI within six months of diagnosis. Patients with CMI were more likely to have a history of smoking (p=0.02) and less likely to be anticoagulated (p<0.01) than patients with asymptomatic MAOD. Symptomatic patients trended towards a higher prevalence of coronary artery disease (p=0.06) and a lower prevalence of arrhythmia (p=0.08). On imaging, the symptomatic cohort was more likely to have severe SMA stenosis (p<0.001), multivessel mesenteric disease (p=0.001), calcified aortic plaque (p=0.01), and severe stenosis in one or both internal iliac arteries (p<0.001). On multivariable analysis, a lack of anticoagulation use (p<0.01) and severe SMA stenosis (p<0.001) were independently associated with higher odds of symptomatic mesenteric stenosis. While statistically insignificant, calcified aortic plaque (p=0.08) and smoking history (p=0.06) trended toward higher odds of symptomatic index presentation. CONCLUSIONS:The rate of progression from asymptomatic MAOD to CMI appears exceedingly low in the first two to three years after diagnosis, suggesting that prophylactic revascularization is mostly unnecessary. Surveillance of asymptomatic MAOD may be personalized based on clinical and radiographic features of disease. SMA stenosis severity, anticoagulation use, and possibly smoking history and the presence of aortic plaque calcification may be promising markers to stratify the risk of ischemic progression.

Altered platelet phenotype in patients with type II endoleaks following abdominal aortic aneurysm repair
Pratama, Muhammad Yogi; King, Benjamin; Teter, Katherine A; Bi, Christina; Presedo, Natalie; Harish, Keerthi B; Giardinetto, Catarina Santos; Belleca, Sheehan; Chervonski, Ethan; Maldonado, Thomas S; Ramkhelawon, Bhama
BACKGROUND/UNASSIGNED:Endovascular abdominal aortic aneurysm repair (EVAR) is a preferred surgery to prevent aneurysm sac enlargement and minimize the risk of life-threatening rupture in patients with AAA. Serious complications of type II endoleaks following EVAR can cause sac expansion and increase rupture risk. This study focused on evaluating clinical and blood characteristics in patients with type II endoleaks to refine our understanding of systemic fluctuations associated with unsuccessful EVAR. METHODS/UNASSIGNED:This retrospective study included 146 patients with AAA who underwent primary elective endovascular procedures (EVAR/fEVAR) between 2013 and 2021. Clinical characteristics, complete blood count (CBC) and imaging data were analyzed from patients who did and did not develop type II endoleaks. RESULTS/UNASSIGNED:Mean platelet volume (MPV) was significantly increased in patients who developed type II endoleaks after EVAR. Receiver operating characteristic analysis showed that MPV has a satisfactory discriminatory performance in distinguishing post-EVAR patients who developed type II endoleaks, yielding an area under the curve (AUC) value of 0.64. A risk stratification panel incorporating MPV, type II diabetes history, and administration of dual antiplatelet therapies yielded an AUC of 0.70 and predicted an endoleak-free survival rate with a hazard ratio of 2.94. A nomogram revealed that MPV had the highest scoring weight among all significant variables. CONCLUSION/UNASSIGNED:Patients with type II endoleaks following EVAR have elevated MPV indicative of different phenotypes of circulating platelets. MPV presents an attractive predictive criteria for assessing the occurrence of type II endoleaks in patients with AAA.

The substantial burden of iatrogenic vascular injury on the vascular surgery workforce at an academic medical center
Rao, Abhishek; Ratner, Molly; Zhang, Jason; Wiske, Clay; Garg, Karan; Maldonado, Thomas; Sadek, Mikel; Jacobowitz, Glenn; Berland, Todd; Teter, Katherine; Rockman, Caron
OBJECTIVE:Vascular surgeons are often called upon to provide emergent surgical assistance to other specialties for iatrogenic complications, both intraoperatively and in the inpatient setting. The management of iatrogenic vascular injury remains a critical role of the vascular surgeon, especially in the context of the increasing adoption of percutaneous procedures by other specialties. This study aims to characterize consultation timing, management, and outcomes for iatrogenic vascular injuries. METHODS:This study identified patients for whom vascular surgery was consulted for iatrogenic vascular complications from February 1, 2022, to May 12, 2023. Patient information, including demographic information, injury details, and details of any operative intervention, was retrospectively collected from February 1, 2022, to October 13, 2022, and prospectively collected for the remainder of the study period. Analyses were performed with R (version 2022.02.03). RESULTS:There were 87 patients with consultations related to iatrogenic vascular injury. Of these, 42 (46%) were female and the mean age was 59 years (±18 years). The most common consulting services were cardiology (32%), cardiothoracic surgery (26%), general surgery (8%), and neurointerventional radiology (10%). Reasons for consultation included hemorrhage (36%), limb ischemia (36%), and treatment of pseudoaneurysm (23%). A total of 24% of consults were intraoperative, 20% of consults related to extracorporeal membrane oxygenation cannulation, and 16% of consults related to ventricular assist devices including left ventricular assist device and intra-aortic balloon pump. The majority of these consult requests (60%) occurred during evening and night hours (5 PM to 7 AM). Emergent intervention was required in 62% of cases and consisted of primary open surgical repair of arterial injury (54%), endovascular intervention (21%), and open thromboembolectomy (15%). Overall, in-hospital mortality for the patient cohort was 20% and the reintervention rate was 23%, reflecting the underlying complexity of the illness and nature of the vascular injury in this patient group. CONCLUSIONS:Vascular surgeons play an essential role in managing emergent life-threatening hemorrhagic and ischemic iatrogenic vascular complications in the hospitalized setting. The complications require immediate bedside or intraoperative consult and often emergent open surgical or endovascular intervention. Furthermore, many of these require urgent management in the evening or overnight hours, and therefore the high frequency of these events represents a potential significant resource utilization and workforce issue to the vascular surgery workforce.

Optimal medical therapy is lacking in patients undergoing intervention for symptomatic carotid artery stenosis and protects against larger areas of cerebral infarction
Teter, Katherine; Willems, Loes; Harish, Keerthi; Negash, Bruck; Warle, Michiel; Rockman, Caron; Torres, Jose; Ishida, Koto; Jacobowitz, Glenn; Garg, Karan; Maldonado, Thomas
OBJECTIVES/OBJECTIVE:Carotid interventions are indicated for both patients with symptomatic and a subset of patients with severe asymptomatic carotid artery stenosis (CAS). Symptomatic CAS accounts for up to 12%-25% of overall carotid interventions, but predictors of symptomatic presentation remain poorly defined. The aim of this study was to identify factors associated with symptomatic CAS in our patient population. METHODS:Between January 2015 and February 2022, an institutional retrospective cohort study of prospectively collected data on patients undergoing interventions for CAS was performed. Procedures included carotid endarterectomy (CEA), transcarotid artery revascularization (TCAR), and transfemoral carotid artery stenting (TF-CAS). Demographic data, comorbidities, procedural details, and anatomic features from various imaging modalities were collected. Comparisons were made between symptomatic (symptoms within the prior 6 months) and asymptomatic patients. RESULTS:< .001), and symptomatic patients with ulcerated plaques more frequently had less than 50% compared to moderate/severe CAS. Nine patients who presented with symptoms had mild CAS and underwent intervention. CONCLUSIONS:Symptomatic CAS was associated with a history of remote prior symptoms and lack of anti-platelet therapy at time of presentation. Furthermore, symptomatic patients not on anti-platelet agents were more likely to have a greater area of parenchymal involvement when presenting with stroke and symptomatic patients with ulcerated plaques were more likely to have mild CAS, suggesting the role of plaque instability in symptomatic presentation. These findings underscore the importance of appropriate medical management and adherence in all patients with CAS and perhaps a role for more frequent surveillance in those with potentially unstable plaque morphology.

Generative artificial intelligence chatbots may provide appropriate informational responses to common vascular surgery questions by patients
Chervonski, Ethan; Harish, Keerthi B; Rockman, Caron B; Sadek, Mikel; Teter, Katherine A; Jacobowitz, Glenn R; Berland, Todd L; Lohr, Joann; Moore, Colleen; Maldonado, Thomas S
OBJECTIVES/OBJECTIVE:Generative artificial intelligence (AI) has emerged as a promising tool to engage with patients. The objective of this study was to assess the quality of AI responses to common patient questions regarding vascular surgery disease processes. METHODS:OpenAI's ChatGPT-3.5 and Google Bard were queried with 24 mock patient questions spanning seven vascular surgery disease domains. Six experienced vascular surgery faculty at a tertiary academic center independently graded AI responses on their accuracy (rated 1-4 from completely inaccurate to completely accurate), completeness (rated 1-4 from totally incomplete to totally complete), and appropriateness (binary). Responses were also evaluated with three readability scales. RESULTS:> .05 for all analyses). CONCLUSIONS:AI offers a novel means of educating patients that avoids the inundation of information from "Dr Google" and the time barriers of physician-patient encounters. ChatGPT provides largely valid, though imperfect, responses to myriad patient questions at the expense of readability. While Bard responses are more readable and concise, their quality is poorer. Further research is warranted to better understand failure points for large language models in vascular surgery patient education.

Speranza, Giancarlo; Harish, Keerthi; Rockman, Caron; Sadek, Mikel; Jacobowitz, Glenn; Garg, Karan; Chang, Heepeel; Teter, Katherine; Maldonado, Thomas S
OBJECTIVE:Investigations into imaging modalities in the diagnosis of extracranial carotid artery occlusion (CAO) have raised questions about the inter-modality comparability of duplex ultrasound (DUS) and cross-sectional imaging (CSI). This study examines the relationship between DUS and CSI diagnoses of extracranial CAO. METHODS:This single-institution retrospective analysis studied patients with CAO diagnosed by DUS from 2010 to 2021. Patients were identified in our office-based accredited vascular laboratory database. Imaging and clinical data was obtained via our institutional electronic medical record. Primary outcome was discrepancy between DUS and CSI modalities. Secondary outcomes included incidence of stroke and intervention subsequent to CAO diagnosis. RESULTS:Of our 140-patient cohort, 95 patients (67.9%) had DUS follow-up (mean, 42.7 ± 31.3 months). At index duplex, 68.0% of individuals (n = 51) were asymptomatic. Seventy-five patients (53.6%) had CSI of the carotids after DUS CAO diagnosis; 18 (24%) underwent magnetic resonance imaging and 57 (76%) underwent computed tomography. Indications for CSI included follow-up of DUS findings of carotid stenosis/occlusion (44%), stroke/transient ischemic attack (16%), other symptoms (12%), preoperative evaluation (2.7%), unrelated pathology follow-up (9.3%), and outside institution imaging with unavailable indications (16%). When comparing patients with CSI and those without, there were no differences with regard to symptoms at diagnosis, prior neck interventions, or hypertension. There was a significant difference between cross-sectionally imaged and non-imaged patients in anti-hypertensive medications (72% vs 53.8%; P = .04). Despite initial DUS diagnoses of carotid occlusion, 10 patients (13.3%) ultimately had CSI indicating patent carotids. Four of these 10 patients had stenoses of ∼99% (with 1 string sign), four of 70% to 99%, one of 50% to 69%, and one of less than 50% on CSI. The majority of patients (70%) had CSI within 1 month of the index ultrasound. There were no significant relationships between imaging discrepancies and body mass index, heart failure, upper body edema, carotid artery calcification, and neck hardware. Eight individuals (10.7%) underwent ipsilateral revascularization; 62.5% (n = 5) were carotid endarterectomy procedures, and the remaining three procedures were a transcervical carotid revascularization, subclavian to internal carotid artery bypass, and transfemoral carotid artery stenting. Eight patients (10.7%) underwent contralateral revascularization, with the same distribution of procedures as those ipsilateral to occlusions. Two of the 10 patients with discrepancies underwent carotid endarterectomy, and one underwent carotid stenting. CONCLUSIONS:In our experience, duplex diagnosis of CAO is associated with a greater than 10% discordance when compared with CSI. These patients may benefit from closer surveillance as well as confirmatory computed tomography or magnetic resonance angiography. Further work is needed to determine the optimal diagnostic modality for CAO.

Short-term outcomes of endovascular management of acute limb ischemia using aspiration mechanical thrombectomy
Auda, Matthew E; Ratner, Molly; Pezold, Michael; Rockman, Caron; Sadek, Mikel; Jacobowitz, Glenn; Berland, Todd; Siracuse, Jeffrey J; Teter, Katherine; Johnson, William; Garg, Karan
OBJECTIVE:Management of acute limb ischemia (ALI) has seen greater utilization of catheter-based interventions over the last two decades. Data on their efficacy is largely based on comparisons of catheter-directed thrombolysis (CDT) and open thrombectomy. During this time, many adjuncts to CDT have emerged with different mechanisms of action, including pharmacomechanical thrombolysis (PMT) and aspiration mechanical thrombectomy (AMT). However, the safety and efficacy of newer adjuncts like AMT have not been well established. This study is a retrospective analysis of the contemporary management of ALI comparing patients treated with aspiration mechanical thrombectomy to patients treated with the more established CDT adjunct, pharmacomechanical thrombolysis. METHODS:Patients undergoing peripheral endovascular intervention for ALI using an adjunctive device were identified through query of the Vascular Quality Initiative (VQI) Peripheral Vascular Intervention (PVI) module from 2014 to 2019. Patients with a nonviable extremity (Rutherford ALI Stage 3), prior history of ipsilateral major amputation, popliteal aneurysm, procedures that were deemed elective (>72 h from admission), procedures that did not utilize an endovascular adjunctive device, and patients without short-term follow-up were all excluded from analysis. The primary outcome was a composite outcome of freedom from major amputation and/or death in the perioperative time period. RESULTS:= 0.05) were associated with the composite outcome. CONCLUSIONS:Short-term amputation-free survival rates of endovascular management of acute limb ischemia are adequate across all modalities. However, aspiration mechanical thrombectomy was associated with significantly worse amputation-free survival compared to other endovascular adjuncts alone (i.e., pharmacomechanical thrombolysis). Severe limb ischemia (Rutherford ALI Stage 2B) and prior supra-inguinal bypass were associated with worse amputation-free survival regardless of the choice of endovascular intervention.

Natural history of internal carotid artery stenosis progression
Harish, Keerthi B; Speranza, Giancarlo; Rockman, Caron B; Sadek, Mikel; Jacobowitz, Glenn R; Garg, Karan; Teter, Katherine A; Maldonado, Thomas S
OBJECTIVE:The aim of this study was to investigate the natural history of internal carotid artery (ICA) stenosis progression. METHODS:This single-institution retrospective cohort study analyzed patients diagnosed with ICA stenosis of 50% or greater on duplex ultrasound from 2015 to 2022. Subjects were drawn from our institutional Intersocietal Accreditation Commission-accredited noninterventional vascular laboratory database. Primary outcomes were incidences of disease progression, and stroke or revascularization after index study. Progression was defined as an increase in stenosis classification category. Imaging, demographic, and clinical data was obtained from our institutional electronic medical record via a database mining query. Cases were analyzed at the patient and artery levels, with severity corresponding to the greatest degree of ICA stenosis on index and follow-up studies. RESULTS:Of 577 arteries in 467 patients, mean cohort age was 73.5 ± 8.9 years at the time of the index study, and 45.0% (n = 210) were female. Patients were followed with duplex ultrasound for a mean of 42.2 ± 22.7 months. Of 577 arteries, 65.5% (n = 378) at the index imaging study had moderate (50%-69%) stenosis, 23.7% (n = 137) had severe (70%-99%) stenosis, and 10.7% (n = 62) were occluded. These three groups had significant differences in age, hypertension, hyperlipidemia prevalence, and proportion on best medical therapy. Of the 467-patient cohort, 56.5% (n = 264) were on best medical therapy, defined as smoking cessation, treatment with an antiplatelet agent, statin, and antihypertensive and glycemic agents as indicated. Mean time to progression for affected arteries was 28.0 ± 20.5 months. Of those arteries with nonocclusive disease at diagnosis, 21.3% (n = 123) progressed in their level of stenosis. Older age, diabetes, and a history of vasculitis were associated with stenosis progression, whereas antiplatelet agent use trended towards decreased progression rates. Of the 467 patients, 5.6% (n = 26) developed symptoms; of those, 38.5% (n = 10) had ischemic strokes, 26.9% (n = 7) had hemispheric transient ischemic attacks, 11.5% (n = 3) had amaurosis fugax, and 23.1% (n = 6) had other symptoms. A history of head and neck cancer was positively associated with symptom development. Of 577 affected arteries, 16.6% (n = 96) underwent intervention; 81% (n = 78) of interventions were for asymptomatic disease and 19% (n = 18) were for symptomatic disease. No patient-level factors were associated with risk of intervention. CONCLUSIONS:A significant number of carotid stenosis patients experience progression of disease. Physicians should consider long-term surveillance on all patients with carotid disease, with increased attention paid to those with risk factors for progression, particularly those with diabetes and a history of vasculitis.
