血管转流管在静脉窦旁脑膜瘤显微全切除手术中的应用

Application of looping vascushunt in the operation of para-sinus meningiomas

目的 评价血管转流管在静脉窦旁脑膜瘤显微全切除术中的应用价值。 方法 2 0 0 0年 2月～ 2 0 0 2年 3月收治静脉窦旁脑膜瘤 18例 ,其中 17例侵犯后 2 /3矢状窦 ,1例侵犯先天单侧横窦。术中全部应用血管转流管 ,在手术显微镜下施行肿瘤切除。 结果 全部病例均全部切除肿瘤和受侵犯之窦壁 (SimpsonⅠ级切除 ) ,12例作人造血管移植重建静脉窦 ,4例行窦壁硬脑膜修补 ,2例因静脉代偿充分仅单纯结扎静脉窦 ,术后恢复好 ,无死亡病例。 结论 血管转流管的应用是保证后 2 /3矢状窦旁及横窦脑膜瘤全切除及顺利进行静脉窦重建的良好技术之一。

Objective Evaluation of application of looping vascushunt tubes in microsurgical total removal of para sinus meningiomas Methods Eighteen patients harboring para sinus meningiomas were treated in our hospital from Feb,2000 to Mar,2002,Tumors were located in the posterior two thirds superior sagittal sinus in 17 patients and in the congenitally isolated transverse sinus in one patient Looping vascushunt were applied in all cases and tumors were removed under microscope using microsurgical techniques Results Tumors and involved sinus walls were resected (Simpson grade Ⅰ) in all patients Venous sinus reconstruction were achieved in 12 patients using artificial blood vessels,sinus walls were repaired with duramater in 4 patient, venous sinus ligation was applied in two patients because of the sufficent collateral venous drainage All patients recovered and no mortality occurred Conclusions Application of vascushunt tubes is one of the important techniques in microsurgical total resection of para sinus meningiomas
