颅后窝实质性血管母细胞瘤的外科治疗

目的 探讨颅后窝实质性血管母细胞瘤外科治疗方法及其疗效。方法 回顾分析27例颅后窝实质性血管母细胞瘤的临床资料。20例行显微手术切除肿瘤，7例经术前栓塞后显微手术切除肿瘤。结果 27例肿瘤均全切除，无死亡病例。术后3例发生轻度颅神经损伤，康复治疗后恢复。结论 对于颅后窝实质性血管母细胞瘤，精确的术前评估并制定相应的手术计划，必要时行术前栓塞肿瘤供血动脉后再行肿瘤切除可减少术中出血，降低手术并发症及病死率。

Surgical treatment of posterior cranial fossa solid hemangioblastomas

Objective To investigate the surgical treatment of solid hemangioblastomas in the posterior cranial fossae. Methods The clinical data of 27 patients with solid hemangioblastomas in the posterior fossae, of whom 20 underwent microsurgery only and 7 underwent microsurgery after the embolization of the arteries feeding blood to the tumors in the recent 5 years, were analyzed retrospectively. Results The tumors were totally resected and no patients died from the surgery in all the patients. Three patients with postoperative mild neurological deficit were recovered by the treatment. Conclusions The accurate preoperative evaluation, making the operative plan and embolization of the arteries feeding blood to the tumors with rich blood supply before the surgery are helpful to reducing surgical complications and mortality in the patients with solid hemangioblastomas in the posterior fossae.
