ryi Our case History 1 Pre-operative 2 Discussion 1.The patient was an old female. Angiography showed bilateral MCA stenosis. 2.Bilateral anterior cerebral arteries originate from the aneurysm neck. The A1 segment of right anterior cerebral artery is not developed. 3.The vasculature architect of the aneurysm indicated long operation time and complex operation procedure. Treatment: 1.The application of general heparinization at the beginning of the procedure. 2.Protecting the left ACA by operating under a proper working projection and with the helping of big coils instead of implanting a stent. 3.Preserving the right A2 by implanting a stent. 4.Y stents will increase the risk of thrombosis. 缺血性并发症危险因素 1.老年女性,双侧大脑中动脉狭窄。 2.双侧大脑前动脉发自瘤颈,右侧A1不发育,如右侧大脑前动脉血流受累,无法通过A1段代偿。 3.该动脉瘤血管构筑提示该病例操作复杂,手术时间预计较长。 策略: 1.术前全身肝素化。 2.栓塞时可通过选择合适的工作角度清楚显示左侧大脑前动脉路径保持该载瘤动脉的通畅性。 3.故本病例仅在右侧大脑前动脉置入支架,使用支架保护技术,左侧大脑前动脉采用大圈保护技术。 4.Y型支架更增加血栓事件可能,单支架简化操作,病人高龄,降低手术风险。 Risk factor of hemorrhagic complication:Anterior communication artery aneurysm with daughter sac. Strategy: 1.Select large coils for stable framing. 2.Daughter sac was the priority, which was embolized by several small soft coils in the beginning of the procedure. 出血性并发症危险因素:前交通动脉瘤伴子瘤形成 策略: 1.使用大圈稳定成篮。 2.优先治疗子瘤,使用小圈填塞。 3 Operation 4 Post-operative 5 Summary |
