To assess predictors of outcome following endovascular treatment of small ruptured intracranial aneurysms (SRA). ⋯ Most patients with SRA can be treated with endovascular therapy and have limited complications. Overall predictors of outcome for patients undergoing endovascular treatment of SRA include age, aneurysm size, Hunt and Hess grade, location and post-treatment vasospasm.

In this case report we describe a successful interdisciplinary approach (including flow redirection and endovascular occlusion) applied to a patient with a continuously growing extracranial giant aneurysm of the right internal carotid artery (ICA) due to known Ehlers-Danlos syndrome. ⋯ This case report describes a successful interdisciplinary approach for the treatment of a rare giant extracranial ICA aneurysm in a patient with Ehlers-Danlos syndrome. Treatment options for this type are few and carry high risks. Flow redirection via extracranial-intracranial bypass followed by endovascular occlusion appears to be a good treatment approach.

Little is known about how much protection a flow diversion stent provides to a non-thrombosed aneurysm without the adjunctive use of coils. ⋯ The flow diversion effects of both stents were limited to flow velocity reduction. In a non-thrombosed aneurysm or an aneurysm with delayed thrombosis, the intra-aneurysmal pressure remains essentially unchanged regardless of the level of the intra-aneurysmal flow velocity reduction induced by the stents.

Treatment of dural arteriovenous fistula involving the transverse-sigmoid region with cortical reflux is complex and treatment options may require sacrifice of the fistulous segment of the sinus. ⋯ Fistulas of the transverse-sigmoid sinuses with cortical reflux may require sacrifice of the parent sinus for cure. Defining the fistulous segment and occluding this segment deliberately, completely and precisely is essential for cure. Several modalities and approaches can be used to achieve this. For properly selected patients, cure of the lesions can be achieved with this method with low risk of morbidity.

Endovascular treatment of ruptured dissecting aneurysms of the posterior inferior cerebellar artery.
Dissecting aneurysms of the posterior inferior cerebellar artery (PICA) are rare, with optimal treatment strategies not well established according to the location of the aneurysm on the PICA. We present our single-center experience of endovascular treatment of ruptured dissecting aneurysms of the PICA. ⋯ Endovascular treatment of ruptured dissecting aneurysms of the PICA is safe and efficient.
