Management of hemorrhagic complications from preoperative embolization of arteriovenous malformations.

摘要: ✓ Endovascular embolization procedures have undergone dramatic evolution and improvement in recent years. Despite these advances, controversy remains regarding the optimal role of treating cerebral arteriovenous malformations (AVM's) whether their purpose should be as a presurgical adjunct or primary therapy. This risks fragmentation between disciplines broader efforts to improve management cerebrovascular disorders. The authors report seven cases life-threatening hemorrhages that occurred during staged invasive therapy for AVM's which illustrate value unified team approach optimize patient care. Each underwent at least one procedure using polyvinyl alcohol particles, followed two by occlusion proximal feeding vessels platinum microcoils case attempted detachment an endovascular balloon. In three patients, catheter penetration into subarachnoid space resulted hem...
