BACKGROUND Ruptured large and partially thrombosed aneurysms are challenging lesions to treat successfully. METHODS We describe the surgical treatment of a large, ruptured partially thrombosed middle cerebral artery (MCA) aneurysm. Once the Sylvian fissure is dissected, temporary clips are placed, and the clot is evacuated with simple microsuction and ultrasonic aspiration. The aneurysm is then carefully clip reconstructed to avoid compromise of the parent vessels. CONCLUSION In cases of surgical clipping of large, thrombosed aneurysms, it is important to be aware of a few, but critically important, pitfalls to ensure successful outcome.

我是怎么做的：一个大的、部分血栓形成的、破裂的大脑中动脉动脉瘤的手术夹重建。

背景破裂的大动脉瘤和部分血栓形成的动脉瘤是成功治疗的具有挑战性的病变。方法 我们描述了一个大的、破裂的、部分血栓形成的大脑中动脉 (MCA) 动脉瘤的手术治疗。一旦侧裂被解剖，放置临时夹子，然后通过简单的显微抽吸和超声波抽吸来排出凝块。然后小心地夹住重建动脉瘤以避免母血管受损。结论 在手术夹闭大的、血栓形成的动脉瘤的情况下，重要的是要注意一些非常重要的陷阱，以确保成功的结果。
