Two-step arterial reconstruction technique for en bloc resection of a large retroperitoneal liposarcoma involving the common iliac artery

Retroperitoneal liposarcoma (RPLS) is a rare but challenging neoplasm, which is frequently associated with iliac vessel invasion. We describe how we used a two-step arterial reconstruction technique to perform en bloc resection of a large RPLS involving the iliac arteries in three patients. A tempor...

Description
Summary:Retroperitoneal liposarcoma (RPLS) is a rare but challenging neoplasm, which is frequently associated with iliac vessel invasion. We describe how we used a two-step arterial reconstruction technique to perform en bloc resection of a large RPLS involving the iliac arteries in three patients. A temporal long in situ graft bypass was established using a prosthetic vascular graft during dissection of the tumor. This bypass provided an unobscured surgical field, while maintaining blood flow in the lower limb during the operation. After removal of the tumor and washing out the abdominal cavity, the new prosthetic vascular graft of a suitable length was placed. No graft-related complications, including vascular graft infection or graft occlusion, occurred during the follow-up period. This novel technique appears to provide a safe and effective way to remove large RPLSs involving the retroperitoneal major vessels.
