[Angiographic study of the vascularization of primary malignant tumors of the liver: histological correlation].
During the last seven years 118 patients with histologic diagnosis of malign tumor in the liver were examinated by selective angiography, amongst other diagnostic recourses: 14 patients had primitive tumors: 12 hepatoma, 1 cholangiocarcinoma and 1 hepatocholangiocarcinoma. In 12 patients resection was contraindicated preoperative by the angiographic demonstration of the extension of the tumor to both lobes. In 1 patient with cholangiocarcinoma, the tumor was resected with an outlive of 4 years. In 1 patient with hepatoma very vascular a hard league of the right hepatic artery was done. Two months later angiography demonstrated a rich revascularisation of the tumor with development of the colateral circulation. In our experience the hiper or hipovascularization is related with the degree of fibrosis which accompanies the tumor and no so much with the histologic type, the degrees of differentiation or the existence of intratumoral necrosis. Emphasis is been done to show the diagnostical difficulties of hipovascularized tumors and the importance of angiography in the preoperative evaluation of hepatic tumors.
