Hepatocellular carcinoma: clinical and angiographic findings and predictability for surgical resection.

Demographic, clinical, and angiographic data were reviewed for 63 consecutive patients with hepatocellular carcinoma. Angiography remains the critical examination in determining extent of disease and potential surgical cure. Angiographic findings were correlated with surgical or autopsy findings for 26 of the patients. The absence of venous invasion and lack of involvement of at least one hepatic segment favor resectability. Selective hepatic injections and oblique views accurately answered these questions in more than 80% of our patients. Pitfalls to angiographic accuracy include vascular invasion by very small tumor masses, hypovascular or diffuse hepatocellular carcinomas, metastatic disease, and involvement of the left lobe.
