title: Hepatic veins in presurgical planning of hepatic resection: what a radiologist should know.
abstract: Hepatic resection is considered to be feasible when all malignant nodules can be technically excised. The goal of the surgical approach is to optimize the oncologic resection (negative margins), sparing the non-cancerous hepatic parenchyma. The outflowing hepatic vein (HV) of that particular liver remnant must be intact in order to preserve its function. The purpose of this article is to familiarize radiologists with anatomy and anatomical variants of HVs, with special emphasis on segmental venous drainage for presurgical planning of hepatic resections. We focus on information which radiologist should give to hepatic surgeon to choose proper surgical approach. Radiologist's familiarity with the anatomy and anatomical variants of HVs is essential for accurate surgical planning to avoid venous congestion as postoperative complication. Any clinically important hepatic vein variation detected on presurgical imaging should be carefully recorded in the radiology report.
