To identify prioritization based on hemorrhagic risk and indications for treatment of arterial and venous aneurysms associated with arteriovenous malformation (AVM). ⋯ In this series, different subtypes of aneurysms associated with AVMs had different clinical behaviors. The bleeding risk of the unrelated aneurysm and the flow-related remote aneurysm types should be considered almost the same as any other unruptured aneurysm. In other words, bleeding risk should be considered taking into account the parameters established by the International Study of Unruptured Intracranial Aneurysms (location, size, and morphology). Conversely, flow-related adjacent aneurysm and venous aneurysm types have significantly higher bleeding potentials.

To evaluate the efficacy of a short interposition graft using saphenous vein or radial artery to connect the proximal superficial temporal artery and the M2 segments of the middle cerebral artery for the treatment of complex intracranial aneurysm. ⋯ Superficial temporal artery-middle cerebral artery bypass surgery using a short interposition graft for intracranial complex aneurysms seems to be safe and efficient hemodynamically after occlusion of the parent artery. It could be regarded as a good alternative to high-flow bypass surgery.
