ARTICLE HIGHLIGHTS
Research background

Portal vein thrombus (PVT) is one of the potentially lethal complication after liver resection; however, its etiology and the way for immediate treatment is unsettled.

Research motivation

Based on our experience, we tried to resolve hepatic failure due to huge PVT.

Research objectives

The study was conducted in patients who underwent open liver resection for cancer in our institution.

Research methods

Retrospective but retrospectively collected cohort.

Research results

In a total of 235 patients, 8 had major PVT. We successfully treated the patients with anticoagulant therapy without adverse events. No hepatic failure observed through this study.

Research conclusions

Performing enhanced computed tomography (CT) on post-operative day 1 is an effective option to find a thrombi at the portal vein close to the surgical site.

Research perspectives

The early detection of PVT by enhanced CT is a promising way to avoid hepatic failure after liver resection.
