[Abdominal visceral occlusion arteriography. A study of technique and diagnostic results compared with the conventional catheter-assessed arteriography (author's transl)].

Since 1976, balloon occlusion arteriography has been performed for diagnostic and therapeutic reasons in about 300 patients. The technical procedure and the safety measure of using balloon catheters with a percutaneous introducer system are described. Compared with the conventional procedure of catheterization of the visceral abdominal arteries, the following advantages were seen in 103 examinations: 1. Simplification of selective and super-selective catheterization due to flow-directed positioning of the balloon tipped catheter in about two thirds of the cases; 2. High contrast in the arterial phase and superior demonstration of smallest arterial vessels in 94% of cases as a result of temporary shorttime complete balloon occlusion of the feeding artery ("standstill-arteriogram"); 3. Early and improved demonstration of the corresponding venous system. The indirect spleno- and mesentericoportogram was improved in 88% of cases; 4. Reduction of the amount of flow, contrast and film material--usually needed--by about 25%. Occlusion arteriography with balloon catheters is a safe and simple method bringing new technical and diagnostic aspects to selective and superselective angiography.
