    Purpose Of ReviewThis review summarizes recent advances in endovascular therapy for cerebrovascular disease.Recent FindingsFor ruptured aneurysms, the only large, randomized, controlled trial comparing surgical and endovascular treatment (the International Subarachnoid Aneurysm Trial) resulted in a significant reduction in death or dependency at 1 year, compared with surgery, providing sound evidence that coiling should be the treatment of first choice. Data from the International Study of Unruptured Intracranial Aneurysms demonstrated that treatment of unruptured anterior circulation aneurysms of under 7 mm with no history of subarachnoid hemorrhage is not justified. Embolization of arteriovenous malformations, as sole therapy, is curative only in a small percentage of cases, but can be part of a multimodal approach for reducing arteriovenous malformation size prior to surgery or radiotherapy. Partial treatment of complex arteriovenous malformations may be more dangerous than no treatment. Protection devices can reduce complication rates in carotid artery stenting, but scientific evidence is still lacking. Until the results of comparative trials are available, carotid artery stenting is indicated only in selected patients. Angioplasty and stenting of intracranial arterosclerotic disease is feasible but remains a high-risk procedure, indicated only in highly selected patients. In acute stroke therapy, new thrombolytics and clot-retrieval devices may result in better recanalization rates.SummaryAdvances in endovascular therapy have occurred in all areas of cerebrovascular disease. To obtain maximal patient benefit, endovascular treatment should be performed as an interdisciplinary approach in high-volume centers. Importantly, long-term follow-up review is necessary to clarify the overall role of endovascular treatment in the management of cerebrovascular disease.
