Twenty-seven patients were evaluated by intra-arterial digital subtraction angiography: 20 for portal hypertension--6 also after a porto-systemic shunt--, 4 for evaluation of a hepatic mass and 3 for pancreatic or biliary tumours. Intra-arterial DSA has always shown vascular abnormalities. The advantage of intra-arterial DSA are reduction of the required amount of contrast medium and, consequent, reduction of the frequency of contrast medium reactions. Its disadvantages are limited field size of image intensifier and reduced spatial resolution as compared with conventional angiography. However diagnosis had never been affected by this limitation.
27例患者接受了动脉内数字减影血管造影评估：20例用于门静脉高压评估——其中6例在进行门体分流术后——，4例用于评估肝脏肿块，3例用于评估胰腺或胆管肿瘤。动脉内数字减影血管造影始终显示出血管异常。动脉内数字减影血管造影的优点是减少了所需的造影剂用量，从而降低了造影剂反应的发生率。其缺点是与传统血管造影相比，影像增强器的视野范围有限且空间分辨率降低。然而，诊断从未受到此限制的影响。
