Abstract

Introduction

Hepatocellular carcinoma (HCC) tends to invade the intrahepatic vasculature, especially the portal vein.1 The presence of portal vein tumor thrombus (PVTT) in patients with HCC is one of the most significant factors for a poor prognosis.25 The presence of macroscopic PVTT in patients with HCC is also a significant factor for poor prognosis, with a median survival of <3 months without treatment.1 In surgically resected series, in patients with gross PVTT (PVTT in the portal trunk, its first-order branch, or its second-order branch), the 3-year and 5-year survival rates are reportedly 15% to 28% and 0% to 17%, respectively.25

Methods

The patient was a 77-year-old woman with well-compensated hepatitis C virus–related cirrhosis (stage A6 according to Child-Pugh classification) who sought care at our department for vague abdominal discomfort. Triphasic spiral computed tomographic scan confirmed HCC 6 cm in diameter in the left lobe of the liver. In addition, portal vein tumor thrombosis of the left branch that extended to the right portal vein was present.

Results

The procedure included left hepatectomy and en-bloc portal vein thrombectomy with clamping of both the common portal vein trunk and the right portal vein. The portal vein was incised at the bifurcation of the right and left portal veins, and the thrombus was extracted from the incision in the portal vein. With this procedure, we were able to examine under direct vision the exact extent of the portal vein thrombus, and we identified whether the tumor thrombus was adherent to the venous wall or was freely floating in the venous lumen.

Portal clamping and length of operation were 16 and 330 minutes, respectively. Intraoperative blood loss was 550 mL. The patient was discharged on postoperative day 6, and she was free of disease at 15 months after surgery.

Discussion

Liver resection should be considered a valid therapeutic option for HCC with PVTT.
