Evaluation of inferior right hepatic vein-preserving hepatectomy with resection of the superior right hepatic vein.

Abstract

IRHV-preserving hepatectomy can retain a greater proportion of liver parenchyma than right hepatectomy. Postoperative liver function was well maintained in our patients and there were no serious complications. Long-term follow-up showed hypertrophy of the remnant posterior sector except in one case. To minimize surgical damage, for example in patients with poor liver function or preoperative complications, IRHV-preserving hepatectomy should be considered.
