Partial Clipping and Multilayered Wrapping Using Collagen Matrix for Partially Thrombosed Basilar Trunk Aneurysm: A Technical Case Report

Treatment of basilar artery trunk aneurysms is still challenging today, although numerous approaches and modalities treatment exist. The authors present a case patient with partially thrombosed, ruptured aneurysm successfully treated by clipping occlusion the rupture point multilayered wrapping aneurysmal dome. A 49-year-old man presented to our emergency room chief complaint altered mental status. was diagnosed subarachnoid hemorrhage (SAH). No apparent bleeding identified on initial 3-dimension computerized tomography (CT) angiography digital subtraction (DSA). Follow-up DSA revealed thrombosed saccular emerging from trunk. We decided treat surgically partial including bleb via anterior transpetrosal approach. surgery performed without any complications, residual blood flow within diminished remarkably over time. Although direct for one most operations, it highly effective complex aneurysms, especially if other treatments are not available.
