Arteriovenous malformations (AVM) can occur in the entire central nervous system with a predilection of the supratentorial intracranial compartment. Intracerebral hemorrhage is the most common clinical presentation of AVM and associated with a high morbidity and mortality rate. ⋯ In this review, the authors present actual diagnostic and interdisciplinary treatment modalities based on their experience in a major neurovascular center and taking into consideration actual literature data. Different treatment strategies are discussed.

Based on findings from the International Subarachnoid Aneurysm Trial (ISAT), coiling of ruptured cerebral aneurysms is associated with the lowest immediate morbidity and mortality rates compared to other treatment options.1, 2 Whenever anatomy permits, coiling is the preferred method for repair. Unfortunately, not all cerebral aneurysms are suitable for coiling, and the best treatment for aneurysms that cannot be coiled remains unclear. Adjunctive techniques such as surgical clipping, balloon remodeling,3 use of two microcatheters,4 and intracranial stents 5 can increase the likelihood of aneurysm thrombosis and parent vessel patency. The goal of this article is to describe our current practice using intracranial stents in appropriately selected patients with subarachnoid hemorrhage (SAH) as a result of aneurysm rupture.

The indications for endovascular coiling of intracranial aneurysms continue to expand. This is due, in part, to the development of intracranial specific stents which permit remodelling of complex aneurysm necks. ⋯ These devices can be used safely and effectively in the treatment of selected ruptured aneurysms. One must weigh the potential hemorrhagic complications against the benefits of stent assisted coiling and the disadvantages of alternative approaches.
