Multistage "Hybrid" (Open and Endovascular) Surgical Treatment of Vertebral Artery-Thrombosed Giant Aneurysm by Trapping and Thrombectomy.
Surgical treatment of vertebral artery (VA)-thrombosed giant aneurysms requires achieving both obliteration of the parent artery to prevent bleeding and dome thrombectomy to relieve the brain stem from mass effect. To secure both proximal and distal control of complex VA aneurysms, the contralateral approach to the aneurysm might be a useful alternative, as previously described. We successfully treated a case of VA-thrombosed giant aneurysm in a new, original way by combining craniotomy (ipsilateral and contralateral) and the endovascular technique. ⋯ Based on pathologic and surgical anatomical characteristics, a combination of an endovascular procedure with 2-staged craniotomy for complete trapping, thrombectomy, and vasa vasorum obliteration could be considered a feasible way to treat VA-thrombosed giant aneurysms located ventral to the brain stem and have their distal neck portions/patent vessel beyond the midline toward the contralateral side.

Stent-assisted coil embolization (SAC) is one of the treatment options for patients with intracranial aneurysms. The purpose of this study was to assess clinical outcomes of patients who underwent coil embolization for acutely ruptured aneurysms without antiplatelet premedication. ⋯ Although procedure-related thromboembolism occurred more frequently, comparable treatment outcomes could be achieved with antiplatelet premedication-free SAC in patients with acutely ruptured aneurysms. The use of stents and thromboembolic complications were not significant risk factors for poor clinical outcome.

There has been controversy as to whether intraventricular hemorrhage (IVH) after aneurysmal subarachnoid hemorrhage (SAH) contributes to angiographic cerebral vasospasm (aCV) and delayed cerebral ischemia (DCI). Computed tomography-based SAH scales that did and did not consider IVH were compared in terms of ability to predict aCV, DCI, and outcome. ⋯ In patients with aneurysmal SAH, IVH is an important factor affecting patient outcome, whereas computed tomography-based SAH scales that do not consider IVH are superior to scales that do consider it for prediction of aCV or DCI.
