BACKGROUND/AIMS: The aim of the study was to present, on the base of own experience, clinical importance of arterio-venous fistulae involving the vascular system of the abdomen. METHODOLOGY: Clinical material consists of 18 @entity1 in whom abnormal arterio-venous leakage in the abdomen was disclosed by means of imaging diagnostic techniques and Doppler sonographic hemodynamic investigations. Three groups of @entity1 were determined: 1. @entity1 in whom @entity7838 was a primary cause of @entity101 (N = 6), 2. @entity1 in whom the presence of arterio-venous fistulae aggravated @entity101 due to other pathology (N = 7). 3. @entity1 in whom the arterio-venous fistulae did not directly affect portal flow (N = 5). As each case presented a different clinical problem, the therapeutic approach had to be individualized. In 12 @entity1 perarterial embolization was performed, 13 @entity1 were operated on, one @entity1 was listed for liver transplantation. RESULTS: Perarterial embolization was fully effective only in 4 cases. In the remaining 8 cases its effect was transient, but in 4 cases of @entity96 it allowed us to proceed with chemoembolization and the others were subsequently treated surgically. In 12 surgically treated @entity1 the operation proved to be curative. In 1 case of multiple arterio-venous fistulae related to @entity2402 , surgical procedure was unfeasible. One @entity1 , awaiting liver transplantation, died of @entity1578 . CONCLUSIONS: 1. Arterio-venous fistulae (of various etiology) are rarely found in the abdominal cavity, but their presence means usually serious consequences depending on their morphology and localization. 2. Arterio-venous fistulae involving the portal system may result in severe @entity101 . 3. Individually chosen method of treatment, aimed at the occlusion of @entity7838 often proves to be curative. 4. Overlooking or ignoring the presence of intraabdominal arterio-venous fistulae leads to unsuccessful, if not harmful treatment.
