✦ Synopsis

Portal vein tumor thrombosis is an important and consistentprognostic indicator in hepatocellular carcinoma. We reviewed 14 cases of ultrasonically guided fine-needle aspiration biopsy (FNAB) of the portal vein. All the patients had clinical evidence of portal vein thrombosis (PVT). Twelve of these patients had a preliminary diagnosis of hepatocellular carcinoma while the remaining two, initially, had a clinical diagnosis of end-stage liver disease. The mean age of the patients was 60 years. An average of 1.7 passes per case was made. No clinical complications were encountered. The cytomorphologic features of the aspirated materials were reviewed. Twelve of the 14 cases (85.7%) were judged neoplastic or thought to have probable neoplastic involvement of the portal vein while two were clearly benign. The cell block was found to be the most useful in diagnosis. We conclude that FNAB of the portal vein is a feasible method in evaluating PVT, especially in patients already known to have hepatocellular carci-
