超选择性栓塞联合显微手术治疗后颅窝实质性血管母细胞瘤

目的 探讨超选择性栓塞联合显微手术治疗后颅窝实质性血管母细胞瘤的临床效果。方法 回顾性分析5例后颅窝实质性血管母细胞瘤患者的临床资料。所有患者均通过栓塞供血动脉后立刻行病灶显微切除术。结果 5例病人肿瘤均全切除，切除术中出血量为（200±80）ml。术后无明显神经功能障碍。术后3个月随访全部病人改良Rankin量表评分均0分，未见肿瘤复发。结论 超选择性栓塞肿瘤供血动脉后立即行病灶显微切除术治疗后颅窝实质性血管母细胞瘤可减少术中出血，缩短手术时间，降低手术并发症及死亡率。

Applicattion of preoperative superselective endovascular embolization to microsurgery for substantial posterior fossa hemangioblastomas

Objective To investigate the clinical value of preoperative supperselective endovascular embolization to microsurgery for the substantial posterior fossa hemangioblastomas. Method The clinical data of 5 patients [male, 3 and female, 2; mean age, (41.2±11.3) years] with the substantial posterior fossa hemangioblastomas who underwent microsurgery immediately after the supperselective endovascular embolization were analyzed retrospectively, including the image data and therapeutic method and effects. Results The total excision of the hemangioblastomas was achieved in all the patients. The intraoperative bleeding volume was (200±80)ml. All the patients were perfectly recovered without any disorder of neurological function. The following up 3 months after the microsurgery showed that all patients had good outcomes (Modified Rankin scale scroe, 0) and the hemangioblastomas did not recurred in the patients. Conclusions The intraoperative bleeding volume and the operative complications may be reduced and operative duration may be shortened by the preoprerative supperselective endovasculative embolization in the patients with substantial posterior fossa hemangioblastomas.
