Contralateral internal iliac artery transposition for retroperitoneal sarcoma involving common iliac artery

AbstractComplete resection for retroperitoneal sarcoma (RPS) involving major vessels frequently requires vascular resection and reconstruction. The use of artificial grafts often leads to postoperative vascular graft infection (VGI), which usually requires reoperation and sometimes leads to death. In the present study, the data of RPS patients who underwent contralateral iliac artery (IIA) transposition for reconstruction of the common iliac artery (CIA) after RPS resection from 2015 –2019 were retrospectively analyzed. Clinical, intraoperative, and postoperative outcomes were described. Contralateral IIA transposition was performed to reconstruct the CIA after segmental resection in three patients. All patients underwent concomitant organ resection. Colon resection was perfor med for all patients, nephrectomy was performed for two patients, and segmental resection of the left ureter with transurethral ureterostomy was performed for one patient. Complete resection was achieved in all patients, and microscopic tumor infiltration to the CIA was observed in all patients (tun ica adventitia: 2, tunica media: 1). No major complications occurred during the hospital stay. During the follow-up period (6.0–29.1 months), one patient died from tumor recurrence, and the other two patients did not have any evidence of recurrence or metastatic disease at the latest follow-up. T he level of lower limb function was favorable (MSTS93 scores: 28–30). The pelvic organ functions, includin...
