西藏高原地区血管内介入治疗破裂颅内动脉瘤

目的 探讨西藏高原地区经血管内介入治疗破裂出血的颅内动脉瘤的安全性、有效性及可行性.方法 回顾性分析2010年1月至2010年11月我院经血管内介入治疗的8例破裂出血的颅内动脉瘤.8例患者均行DSA检查确诊,并根据动脉瘤的特点实施个性化血管内介入治疗:5例行弹簧圈栓塞术,2例行支架辅助弹簧圈栓塞术,1例行单纯支架贴敷术.结果 8例中完全栓塞6例,次全栓塞1例,单纯支架贴敷1例.术中复查DSA显示:动脉瘤显影消失7例,单纯支架置入后瘤腔内对比剂滞留1例.1例宽颈动脉瘤行支架辅助弹簧圈栓塞术后出现对侧肢体偏瘫(肌力0级),经给予加强抗凝、抗血小板聚集、改善微循环等治疗后,下肢肌力恢复至Ⅴ级,上至肌力恢复至接近Ⅴ级.除术前Hunt-Hess分级Ⅳ级、GCS评分4分的1例因继发严重脑积水恢复至Hunt-Hess分级Ⅲ级、GCS评分7分外,其余7例均恢复正常.门诊随访1-5个月,无再出血或缺血事件发生.结论 高原地区经血管内介入治疗破裂出血的颅内动脉瘤是安全、有效的,但围手术期的处理具有高原特色.

Abstract：

Objective To evaluate the safety, efficacy and feasibility of endovascular interventional therapeutic techniques for ruptured hemorrhagic intracranial aneurysms in highland in Tibet. Methods Retrospectively analyzed the therapeutic effects of endovascular interventional treatment for ruptured hemorrhagic intracranial aneurysms in 8 cases in highland in Tibet 8 cases were performed DSA for accurate diagnosis and individualized endovascular interventional treatment were undergone according to the feature of the aneurysms; coiling in 5 cases, coiling with assistance of stent in 2 and pure stenting in 1. Results Among the 8 cases complete embolization was gained in 6 and hypo - complete embolization in 1. DSA review during procedure showed the image of aneurysm disappeared in 7 cases and retention of contrast agent inside the aneurysm in the case which was purely stented. Contralateral hemiplegia of limbs which muscle strength was 0 grade occurred in 1 case with wide - necked aneurysm treated by coiling with stent assistance after procedure. After the intensive treatment of antiplatelet, anticoagulation and to improve microcirculation, the muscle strength recovered to Ⅴ grade in the lower limb and near Ⅴ grade in the upper limb. After procedure except 1 case whose Hunt & Hess grade was in Ⅵ and GCS was 4 improved Hunt & Hess grade to Ⅲ and GCS to 4 because of secondary severe hydrocephalus, the other cases were all well recovered. During 1 to 5 months following - up of outpatient no re - hemorrhagic or ischemic event occurred. Conclusions Endovascular interventional treatment is safe, mini- invasive, effective and feasible for ruptured hemorrhagic intracranial aneurysms in highland in Tibet, but the peri - operative management was highland characteristic.
