椎体血管瘤栓塞治疗的临床应用价值

The treatmental value of embolization to vertebral hemangioms

目的 :探讨椎体血管瘤的术前栓塞和单纯栓塞的意义。方法 :经栓塞治疗的椎体血管瘤 18例。方法是先行节段动脉及其他供血动脉造影。经导管注入栓塞剂栓塞。术前栓塞用明胶海绵GS和聚乙烯醇Ivalon ,单纯栓塞用Ivalon和无水酒精。结果 :术前栓塞后肿瘤染色大部或完全消失者术中出血显著减少 ,单纯栓塞肿瘤染色大部或完全消失者。临床症状消失 ,3～ 6个月后复查平片示病变椎体不同程度增生硬化。 2例复查MR未显血管瘤信号。结论 :术前栓塞可减少术中出血 。

Objective:To investigate the treatmental values of embolization alone and embolization before operation to vertebral hemangiomas.Methods:18 cases of vertebral hemangiomas patients were treated by embolization.After their femoral arteries had been catheterized,angiography were performed to show segmental arteries and other blood supplying arteries,then Ivalon and anhydrous alcohol were injected into the blood supplying arteries to embolize alone,but the gelatin sponge and Ivalon were used to embolize before operation.Results:In patiens embolized before operation,postembolization angiogram demonstrated complete or partly obliteration of tumor stain,and the bleeding amounts in operation were reduced significantly.Clinical symptoms disappeared in patients whose angiography showed absence of the tumor blush embolized with Ivalon and alcohol,and their X ray films demonstrated the suffered vertebral proliferated and sclerosed 3 to 6 months later,2 cases had no singal showing hemangioma on MRI.Conclusion:Embolization before operation could reduce bleeding amount and we hoped that embolization alone could cure vertebral hemangiomas.
