Self-expanding stents are increasingly used for treatment of complex intracranial aneurysms. We assess the safety and the efficacy of intracranial stenting and determine predictors of treatment outcomes. ⋯ Stent-assisted coiling of intracranial aneurysms is safe, effective, and provides durable aneurysm closure. Higher complication rates and worse outcomes are associated with treatment of ruptured aneurysms. Stent delivery before coil deployment reduces the risk of procedural complications. Staging the procedure may not improve procedural safety. Closed-cell stents are associated with significantly lower recanalization rates.

To date, there is no immediate radiographic surrogate to quantify primary cerebral injury to identify patients at risk for delayed cerebral ischemia and poor clinical outcome after aneurysmal subarachnoid hemorrhage. Therefore, we investigated the relation of early cerebral perfusion-computerized tomography and clot volume with radiological events of delayed cerebral ischemia and clinical outcome in patients with aneurysmal subarachnoid hemorrhage. ⋯ Assessment of early cerebral perfusion and intracranial blood clot may serve as a radiographic surrogate for delayed cerebral ischemia and functional outcome in patients with aneurysmal subarachnoid hemorrhage using risk group modeling.
