These data confirm the safety and efficacy of endovascular coil occlusion for patients with intracranial aneurysms.

Stent grafts are a useful tool for the endovascular treatment of head and neck aneurysms and direct arteriovenous fistulae in selected patients. The major disadvantage of the currently available stent grafts is their lack of mechanical flexibility. Maneuvering stent grafts in the intracranial arteries carries the risk of iatrogenic vessel dissection and may require supportive measures and protection of the target site by conventional stents.

Potentially, more than half the patients with WFNS Grade-4 and -5 SAH who are treated aggressively with coil embolization in association with supportive neurocritical care can achieve a good quality neurological outcome. However, it should be anticipated that these patients will spend a significant period of time in neurocritical care.
