Abstract
Background
Although hepatectomy including inferior vena cava (IVC) resection is becoming more common, some details remain uncertain such as use of artificial materials to replace a tumor-involved, damaged, or narrowed retrohepatic IVC segment.
Methods
Surgical outcomes of 12 patients who underwent hepatectomy with IVC resection including reconstruction using synthetic tubular grafts were investigated to clarify safety and feasibility.
Results
Operative time (median, 573 min; range, 268 to 774) and the blood loss (1076 mL; 155 to 2960) were acceptable. In-hospital mortality was 8% (1/12), and morbidity was 42% (5/12). Among the 12 patients, 2 were planned to undergo IVC reconstruction without an artificial graft. In one patient, prosthetic repair was adopted because of massive bleeding from the IVC wall during dissection of tumor from the IVC. In the other, severe stricture became evident during attempted direct closure of the partially resected IVC wall.
Discussion
Ongoing experience has increased our acceptance of combined liver and IVC resection. We believe that segmental IVC resection and reconstruction with a prosthetic tubular graft could be chosen more frequently in managing liver tumors suspected to involve the IVC.
