摘要
目的 探讨术前栓塞对中枢神经系统血管母细胞瘤手术切除的作用。方法 11例经CT、MRI及DSA检查诊断为中枢神经系统血管母细胞瘤患者 ,8例病变位于小脑 ,1例位于延髓 ,2例位于脊髓胸段内。手术切除前均在局麻下经微导管行供血动脉PVA颗粒栓塞。栓塞后均行手术切除肿瘤。结果 微导管均到达供血动脉 ,注入适量直径为 2 5 0～ 3 5 0 μmPVA颗粒后 ,6例完全栓塞 ,肿瘤血管和肿瘤染色完全消失 ;5例大部栓塞 ,肿瘤血管和肿瘤染色仅存小部分。 11例栓塞后均顺利实施肿瘤手术切除。与既往未栓塞的病例相比较 ,行术前栓塞的病例手术时肿瘤界限清楚 ,术中出血减少 ,手术视野清晰 ,不易误伤邻近正常结构 ,容易分块切除 ,手术时间缩短 ,6例完全栓塞者表现尤为显著。 11例手术均未出现并发症。结论 术前栓塞对血管母细胞瘤手术切除可使肿瘤切除更为容易 ,临近正常结构不易损伤 ,手术时间缩短 ,术中出血明显减少 。
Objective To determine whether preoperative embolization is a valuable adjunct to surgical excision of hemangioblastoma. Methods Eleven cases of hemangioblastoma, involving 8 of cerebellum , 1 of medulla oblongata and 2 of spinal cord shown by CT, MR and DSA were embolized preoperatively. The feeding arteries were catheterized with microcatheter and devascularized with polyvinyl alchol particles. Results The blood supplies of the tumor in 6 cases were completely eliminated, and partial occlusion through embolization were undergone for the other 5 cases. Surgical operation was undergone 1-7 days later with all, the 11 tumors totally resected acompanied by minimal blood loss and shortening of the operation time. In addition, manipulation and removal of these embolized tumors were actually easier than expected. No complications occurred during the procedures of embolization and operation. Conclusions Preoperative embolization of hemangioblastoma is a useful and relatively safe to surgical complete resection of this hypervascular tumor with significant reduction of blood loss and operation time.
