The incidence of aneurysms coexisting with arteriovenous malformations (AVMs) ranges between 2.7 and 16.7%. The anatomical relationship between the AVM and the aneurysm is critical in deciding the best management. As a broad guide, this relationship can be classified as follows: 1) aneurysms unrelated to the AVM; or 2) aneurysms ...

Summary: We describe three patients who presented with spontaneous intracerebral hemorrhage resulting from the close association of developmental venous anomaly (DVA) and arteriovenous malformation (AVM). Angioarchitecturally, either the DVA formed the draining pathway for the AVM or they shared a common venous channel. The AVMs were treated by targeted embolization ...
Zanow Jurgen - - 2006
Arteriovenous access-related ischemia is an uncommon but serious and occasionally devastating complication. Distal revascularization-interval ligation (DRIL) has been established as a standard treatment procedure; however, an axial artery is ligated and the distal perfusion is maintained by the construction of an arterial bypass. Because such an approach, in principle, appears ...
