Abstract

Objective: A ruptured aneurysm rarely causes a primary intraventricular hemorrhage. Cases of aneurysms concomitant with internal carotid artery occlusion are occasionally reported; however, no previous studies have described lateral posterior choroidal artery (LPChA)-associated aneurysms with internal carotid artery occlusion.

Case presentation: We experienced a case of intraventricular hemorrhage caused by the rupture of an LPChA aneurysm associated with the collateral circulation of internal carotid artery occlusion. After a detailed preoperative imaging study, the embolization was successfully achieved using n-butyl-2-cyanoacrylate without new neurological deficits.

Conclusion: This case highlights the importance of knowledge of the functional anatomy of collateral anastomosis of the intraventricular choroidal arteries, which allowed safe and successful embolization of the aneurysm.

n -丁基-2-氰基丙烯酸酯栓塞后侧脉络膜动脉瘤合并颈内动脉闭塞1例。

目的：动脉瘤破裂很少引起原发性脑室内出血。动脉瘤合并颈内动脉闭塞的病例偶有报道；然而，以前没有研究描述外侧后脉络膜动脉（LPChA）相关动脉瘤合并颈内动脉闭塞。病例介绍：我们经历了一例脑室内出血，由LPChA动脉瘤破裂引起的内颈动脉侧支循环闭塞。经过详细的术前影像学检查，使用2-氰基丙烯酸丁酯成功栓塞，无新的神经功能缺损。结论：本病例强调了脑室内脉络膜动脉侧支吻合功能解剖学知识的重要性，可以安全、成功地栓塞动脉瘤。
