Hypogastric Artery Transposition to Restore the Arterial Flow after Resection of the External Iliac Artery.

Tumors in the pelvic cavity frequently involve the iliac vessels. Common and external iliac arteries should be reconstructed to restore the flow to the lower extremity if the tumor directly invades these arteries. We report herein a 58-year-old female patient with a 10×11 cm, recurred uterine leiomyosarcoma. We performed en bloc resection of the tumor mass including the sigmoid colon, left ureter and 5 cm of the left external iliac artery. After complete resection, restoration of arterial flow to the lower extremity was made with a novel strategy of hypogastric artery transposition. There was no evidence of tumor recurrence or vascular insufficiency at 12 months after surgery.
