Abstract：
UNASSIGNED: Distal posterior inferior cerebellar artery (PICA) aneurysms are exceedingly rare intracranial aneurysms. In the acute phase of rupture, interventions commonly involve parent artery occlusion through endovascular treatment or direct trapping surgery. There is no consensus on the best treatment of chronic ruptured or unruptured aneurysms, and stent-assisted coil embolization has not yet been reported in the chronic phase of rupture.
UNASSIGNED: We present a case of a 46-year-old female with a recurrent distal PICA aneurysm at 18 months following the initial treatment for subarachnoid hemorrhage and was treated by stent-assisted coil embolization with Neuroform Atlas (Stryker, USA), with a favorable outcome.
UNASSIGNED: Distal PICA aneurysms occur at the apical curvature, where primitive arterial anastomoses existed during development, pointing to the potential vulnerability of the vessel wall at these sites. Stent-assisted coil embolization has shown effectiveness in preserving the parent artery for chronic ruptured and unruptured distal PICA aneurysms. Nonetheless, the narrowness and tortuosity of the PICA present obstacles to treatment. In our case, the procedure was feasible utilizing the Neuroform Atlas (Stryker, USA) with the Transcell approach. A thorough grasp of the characteristics of stents and their application is pivotal for achieving effective treatment outcomes.

摘要：
■远端小脑后下动脉（PICA）动脉瘤是极为罕见的颅内动脉瘤。在破裂的急性期，干预通常涉及通过血管内治疗或直接捕获手术进行的母动脉闭塞.关于慢性破裂或未破裂动脉瘤的最佳治疗方法尚无共识。而支架辅助弹簧圈栓塞在慢性破裂阶段尚未见报道。
■我们介绍了一例46岁的女性，在蛛网膜下腔出血的初始治疗后18个月出现了远端PICA动脉瘤，并通过支架辅助线圈栓塞治疗了NeuroformAtlas（Stryker，美国),一个有利的结果。
■远端PICA动脉瘤发生在根尖弯曲处，在发育过程中存在原始动脉吻合，指出这些地点的容器壁的潜在脆弱性。支架辅助线圈栓塞术已显示出有效的保留慢性破裂和未破裂的PICA远端动脉瘤的父动脉。尽管如此，PICA的狭窄和弯曲对治疗构成障碍。在我们的案例中,利用NeuroformAtlas(Stryker，美国）采用Transcell方法。彻底掌握支架的特性及其应用对于实现有效的治疗效果至关重要。
