Chylous Leak During Posterior Approach to Juvenile Scoliosis Surgery: A Case Report [Case Report]

Shah, Harsh A; Rynecki, Nicole; Vives, Michael J; Choi, Daniel E; Sambol, Justin T; Sabharwal, Sanjeev
CASE:We report the first documented case of chylous leak recognized intraoperatively during posterior spinal instrumentation and fusion for juvenile scoliosis in a female patient with a history of thoracotomy and decortication for an empyema. CONCLUSIONS:Thoracic duct injury can lead to severe morbidity and mortality because of chylothorax formation. Although chylous leaks are a well-documented complication of the anterior approach to spine surgery, leaks during the posterior approach are rarely reported. When these chylous leaks are recognized intraoperatively, the likelihood of serious complications may be minimized by drain placement before closure.

Do postoperative drain volumes correlate with intraoperative blood loss and postoperative transfusion requirements in posterior spinal fusion for adolescent idiopathic scoliosis?

Choi, Daniel E; Vives, Michael J; Shah, Harsh; Zhao, Caixia; Patel, Anuradha; Sabharwal, Sanjeev
Most studies have excluded postoperative drain volumes in analyzing blood loss associated with scoliosis surgery. We sought to analyze patient and surgical factors that influenced postoperative drain outputs. A retrospective review was conducted on 50 consecutive patients who had undergone posterior spinal fusion with pedicle screw instrumentation and subfascial drain placement over a 6-year period at a single institution for adolescent idiopathic scoliosis. Postoperative drain volumes were correlated to patient factors, surgical variables, and change in postoperative hemoglobin values. The association between drain output volumes and the need for allogeneic blood transfusion was also analyzed using univariate and multivariate analysis. Total postoperative drain volume positively correlated with Cell Saver volume (r=0.28, P=0.049), units of packed red blood cells transfused intraoperatively (r=0.31, P=0.03), and a number of Ponte osteotomies (r=0.43, P=0.002). On the basis of multiple linear regression analysis, only the number of osteotomies performed was associated with increasing total drain volume (R=0.25, P=0.003). Total drain output did not correlate with postoperative change in hemoglobin (P=0.85), the need for postoperative blood transfusion (P=0.22), or the total volume of blood transfused perioperatively (P=0.06). Patients with large intraoperative blood loss or multiple osteotomies are more likely to have higher postoperative drain volumes. Drain volume alone, however, should not be used as a trigger for recommending a postoperative blood transfusion.

Upper extremity compartment syndrome after minor trauma: an imperative for increased vigilance for a rare, but limb-threatening complication

Seigerman, Daniel A; Choi, Daniel; Donegan, Derek J; Yoon, Richard S; Liporace, Frank A
BACKGROUND: Compartment syndrome of any extremity is a limb-threatening emergency requiring an emergent surgical management. Thus, ruling out compartment syndrome is often high on the list of priorities when treating high-energy injuries and fractures. However, even in the most seemingly benign injuries, this dangerous diagnosis must always remain on the differential and suspicion must remain high. CASE PRESENTATION: 23-year-old factory worker presents after a low energy entrapment injury to his left forearm. Initial work-up and evaluation noted an isolated radial head dislocation with a normal physical motor and sensory exam. However, maintaining high suspicion for compartment syndrome despite serial normal physical exams, led objective compartment pressure measurement leading to definitive diagnosis. Emergent surgical intervention via compartment fasciotomies was performed, along with closed reduction and ligament repair. At 1 year follow-up, the patient was well-healed, back to work with full range of motion and not activity limitations. CONCLUSION: Despite a seemingly benign injury pattern, and a relatively low energy mechanism, vigilant concern for compartment syndrome following any kind of entrapment injury should initiate serial examinations and compartment pressure measurements especially in circumstances with continued swelling and inability to perform an accurate clinical assessment due to an obtunded or medicated patient.

Pediatric uveitis secondary to probable, presumed, and biopsy-proven sarcoidosis [Case Report]

Choi, Daniel E; Birnbaum, Andrea D; Oh, Frederick; Tessler, Howard H; Goldstein, Debra A
PURPOSE/OBJECTIVE:To describe pediatric patients with uveitis diagnosed as having sarcoidosis. METHODS:Medical records of pediatric patients evaluated between 1987 and 2008 were reviewed to identify those with ocular inflammation in whom a diagnosis of sarcoidosis was considered. A classification system including ocular findings and results of laboratory testing was devised and used to classify likelihood of sarcoidosis. RESULTS:Four hundred sixty children younger than 17 years were evaluated. Based on the classification system designed, 13 patients (2.8%) had probable, presumed, or definite sarcoidosis. The mean age was 11.6 years (range: 5 to 16 years). Elevated angiotensin-converting enzyme was measured in 6 patients and lysozyme in 5 patients. Five of 12 patients in whom chest imaging was performed had signs of sarcoidosis. Anterior segment involvement was non-granulomatous more often than granulomatous. Seven patients had multifocal choroiditis and 4 patients had retinal periphlebitis. CONCLUSION/CONCLUSIONS:Ocular sarcoidosis is uncommon in children, even at a tertiary referral center. Pulmonary involvement was detected in slightly less than half of the patients who had imaging, in contrast to previous reports of almost universal lung involvement in children 8 to 15 years old. The classification system of presumed, probable, and definite sarcoidosis presented may be useful in clinical practice.
