A 63-year-old woman presented with a ruptured aneurysm which apparently spontaneously thrombosed. She was admitted after sudden onset of severe headache. Computed tomography (CT) demonstrated subarachnoid hemorrhage (SAH) in the pontine and interpeduncular cisterns. Initial three-dimensional CT (3D-CT) angiography revealed an aneurysm (diameter, 9 mm) near the origin of the left superior cerebellar artery. However, angiography 3 hours later failed to show the aneurysm. Total thrombosis was thought to have occurred in the aneurysm. The patient returned home with no deficit 1 month after admission. T(1)- and T(2)-weighted magnetic resonance imaging 75 days after the SAH demonstrated the thrombosed aneurysm as an isointense mass lesion. 3D-CT angiography showed no recanalization of the aneurysm 9 months after the SAH.

Objective: Flow diversion is increasingly used as an endovascular treatment for intracranial aneurysms. FRED-EPI is a prospective, multicenter, French study, conducted to analyze the safety and efficacy of aneurysm treatment with FRED/FRED Jr (Microvention, AlisoViejo, CA, USA) in current clinical practice.
Patients And Methods: Patients with intracranial aneurysms treated with FRED and FRED Jr who agreed to participate were prospectively and consecutively included in all French centers using these devices.

Background: Wall shear stress (WSS) plays a crucial role in the natural history of intracranial aneurysms (IA). However, spatial variations among WSS have rarely been utilized to correlate with IAs' natural history. This study aims to establish the feasibility of using spatial patterns of WSS data to predict IAs' rupture status (i.

TAAs involving the proximal arch require adequate coverage with thoracic endovascular aortic repair, which is timely and challenging in emergent ruptures. In situ laser fenestration is a novel method of arch revascularization.

Mycotic aneurysms are rare but severe complications that can arise from systemic bacterial infections, including those caused by Salmonella species. These aneurysms can progress rapidly and are associated with high mortality. A 62-year-old man with poorly controlled type 2 diabetes mellitus presented to the hospital in septic shock.

Traumatic aneurysms represent less than 1 percent of intracranial aneurysms and middle meningeal artery pseudoaneurysms are even rare. Traumatic aneurysms are usually pseudoaneurysms formed by the rupture of all the layers of the vessel wall. They are associated with high mortality as they can present as epidural, subdural, and rarely intraparenchymal hematoma.
