title: Hepatic intra-arterial lipiodol ultrasound guided biopsy in the management of hepatocellular carcinoma.
abstract: One hundred and fifty-one consecutive new patients with suspected hepatocellular carcinoma (HCC) were investigated from 1989 to 1990. Ultrasound showed the tumours to be inoperable in 111 patients. Selective hepatic angiography revealed 17 more patients with inoperable HCC. Hepatic intra-arterial lipiodol (HIAL) was injected in the remaining 23 patients. In 16 of them, a clinical decision could be reached basing on the radiological findings. Hepatic intra-arterial lipiodol ultrasound (HIAL/USG) guided biopsy was done in seven patients with suspicious lesions. Histology obtained with this method revealed hyperplastic cirrhotic nodules in four patients (two with suspected HCC and two with suspected secondaries). In another two patients, the suspected lesions were confirmed to be malignant. In the last patient who had received chemotherapy for extensive HCC, HIAL/USG guided biopsy revealed necrotic tissue only. At laparotomy, diffuse infiltrative abnormality was found and repeated biopsy confirmed residual malignancy in the necrotic tumour. We conclude that when there is radiological uncertainty as to the nature and extent of the HCC, HIAL/USG guided biopsy can help the clinician to make important decisions.
