The use of free microvascular techniques to improve the results of Van Nes rotationplasty [Case Report]
Tiwari, Pankaj; Agrawal, Nikhil; Kocak, Ergun
Van Nes rotationplasty is a limb-salvage used for reconstruction after resection of a distal femoral or proximal tibial osteosarcoma in the pediatric patient. After resection, the distal leg is reapproximated to the level of tumor resection. The goal is to optimize extremity functionality such that the ankle functions as a knee joint. Traditionally, the vessels and nerves around the tumor are preserved within the distal leg. In the first case of our series, this method resulted in thrombosis, flap loss, and ultimately amputation secondary to venous torsion and thrombosis. In the following 2 cases, the intervening vasculature was resected along with the tumor, and the distal pedicles were anastomosed to their proximal counterparts using microvascular techniques. In addition to expediting resection of the tumor as well as allowing wider tumor resection margins, this technique also precludes thrombosis and subsequent flap loss.

Outcomes analysis of the role of plastic surgery in extremity sarcoma treatment
Agrawal, Nikhil; Wan, Dinah; Bryan, Zachary; Boehmler, James; Miller, Mike; Tiwari, Pankaj
Over the past 5 years we have developed a multidisciplinary service for the treatment of extremity sarcoma. This service includes orthopedic oncology, neurosurgery, medical and radiation oncology, and plastic surgery. Prior to 2007, the role of plastic surgery in this multidisciplinary team was limited. After 2007, plastic surgery at our institution played an increasingly integral role in multidisciplinary care. Based on the development of the plastic surgery service at our institution, we were able to evaluate the role of plastic surgery in the outcomes following extremity reconstruction after sarcoma resection. We hypothesize that plastic surgery involvement would reduce the amputation rate without altering recurrence rates. We found a decrease in lower-extremity amputation of approximately 20% without any significant change in recurrence rates. The incidence of infectious complications requiring IV antibiotics decreased by about 20%. The incidence of skin graft loss decreased by 75%. We do report a significant increase in partial flap necrosis. Overall, plastic surgery is an essential component of the multidisciplinary team in the care of extremity sarcoma.

Surgical management of silicone mastitis: case series and review of the literature
Echo, Anthony; Otake, Leo R; Mehrara, Babak J; Kraneburg, Ursula M; Agrawal, Nikhil; Da Lio, Andrew L; Shaw, William W; Lee, Gordon K
BACKGROUND:Free silicone injection for breast augmentation, which became widespread in the 1960s and continues illicitly to this day, has well-known adverse effects. In this retrospective chart review of 14 patients treated for silicone mastitis from 1990 to 2002, we present our experience with the surgical management of patients with silicone mastitis. METHODS:All the patients were women, ranging in age from 49 to 76 years old (mean age = 58.8). Patients presented to us a mean of 29.9 years after their free silicone breast injection. Treatment modalities were analyzed, and, specifically, methods of breast reconstruction involving autologous tissue transfers, implants, or a combination were evaluated. RESULTS:The majority of patients (12 of 14) required mastectomies for extensive silicone-infiltrated tissues. The remaining two patients had focal areas of disease and were successfully treated with excision and local breast parenchyma flaps. Autologous reconstruction was performed with a total of 20 flaps, including 12 free transverse rectus abdominis myocutaneous flaps, 4 free superior gluteal artery perforator (SGAP) flaps, and 4 pedicled latissimus dorsi (LD) flaps. Two patients had bilateral implant-based breast reconstruction. CONCLUSION/CONCLUSIONS:A variety of reconstructive options are available for patients presenting with silicone mastitis. Once an appropriate breast cancer workup has been performed, the surgical goal is to excise as much of the silicone-infiltrated tissues as possible before reconstruction. To our knowledge, this is the first reported series that incorporates the use of SGAP and LD flaps as a means of autologous tissue reconstruction for silicone-infiltrated breasts.
