ARTERIOVENOUS-FISTULAS COMPLICATING CENTRAL VENOUS CATHETERIZATION - VALUE OF ENDOVASCULAR TREATMENT BASED ON A SERIES OF 7 CASES

Objectives: To point out the usefulness and effication of endovascular treatment of arteriovenous fistulae complicating the insertion of cen tral venous catheter. Material and method: Retrospective study of 7 ca ses treated between 1983 and 1993. The central venous catheterization had involved the right internal jugular vein in 5 cases and the right subclavian vein in 2 cases. Results: Isolated endovascular therapy was performed in 5 cases. Surgery was necessary in 1 case to remove an he matoma. In another case, occlusion of a large AVF was performed during intraoperative endovascular temporary occlusion of the AVF The choice of the occluding agent was primarily dictated by the hemodynamic and anatomical conditions (releasable balloons, coils). Vertebro-vertebral fistulae (3 cases) could be treated with patency of this vessel. No c omplications were encountered. Conclusion: Endovascular approach is a reliable and safe method to perform occlusion of post catheter AVF.
