title: [A comparative diagnostic study of malignant lesions of the liver by infusion angiography and percutaneous transhepatic portography (author's transl)].
abstract: The diagnostic effectiveness of percutaneous transhepatic portography (PTP) was evaluated in 21 patients with primary and metastatic liver carcinoma, who also had infusion hepatic angiography. The findings at PTP were compared with unequivocal tumor changes demonstrated at infusion hepatic angiography in all cases. PTP revealed tumors in 14 of 21 cases. The location, size and number of the tumor(s) were decisive for their detectability at PTP. Solitary lesions smaller than 2 cm in the central parts of the liver escaped detection, whereas lesions larger than 7 cm in the left lobe and 6 cm in the right lobe were demonstrated in all cases. Multiple metastases of 1--2 cm were detected in most cases. Lesions smaller than 4 cm were better shown by the sinusoidal phase at PTP, where lesions larger than 5 cm were better delineated by the portal venous phase.
