Rapid and progressive venous thrombosis after occlusion of high-flow arteriovenous fistula.
Cerebral venous thrombosis developing after surgical or endovascular obliteration of arteriovenous fistula (AVF) is a rare but devastating complication that has not been adequately reported. ⋯ Rapid occlusion of a high-flow AVF resulting in significant venous stasis can precipitate thrombosis of the venous system distal to the fistulous point. In the presence of large venous pouches and significant venous stasis, strict therapeutic anticoagulation may be required to prevent cerebral venous thrombosis. Therapeutic anticoagulation, though feasible following endovascular treatment, may prove particularly challenging after open surgical interventions given the risk of hemorrhagic complications.
