Right External Iliac Artery Resection and Reconstruction Because of Cecum Cancer Invasion: A Case Report

This report describes the case of a 69-year-old female patient. At the age of 68, she was diagnosed with cecum cancer, and infiltration of the right external iliac artery was detected. Owing to arterial infiltration, surgical resection was considered inappropriate, and a future risk of intestinal obstruction in the cecum region was anticipated. Therefore, a laparoscopic ileum-transverse colon bypass was performed. Subsequently, chemotherapy with the FOLFOXIRI (folinic acid, fluorouracil, oxaliplatin and irinotecan) regimen plus bevacizumab was administered for five months. Contrast-enhanced computed tomography revealed reduced infiltration of the right external iliac artery, prompting plans for ileocecal resection with combined resection of the right external iliac artery and iliopsoas muscle. After resection of the intestine, preserving the bypass site and tissue mobilization except the right external iliac artery infiltration site, systemic heparinization was performed. An 8 mm artificial vessel was then interposed to reconstruct the right external iliac artery using an end-to-end anastomosis technique. Lower extremity blood flow was unremarkable, and the postoperative course was uneventful. The patient was discharged on postoperative day 10 without complications.
