脊柱肿瘤术前靶动脉栓塞

目的　探讨脊柱肿瘤术前栓塞的临床应用价值。方法　肿瘤分布为颈椎 13例 ,胸椎 17例 ,腰椎 15例 ,骶椎 9例。造影后选择性栓塞肿瘤供养动脉 ,栓塞物质为直径 1mm的明胶颗粒、PVA颗粒或钢圈。手术时机为栓塞后 1～ 7d。结果　共栓塞 4 3例患者的 79支血管 ,其中颈升动脉 1支 ,椎动脉 1支 ,肋间动脉 39支 ,腰动脉 19支 ,髂内动脉 15支 ,骶正中动脉 4支。栓塞后手术的 4 1例患者术中估计出血量 (EBL)为 30 0～ 30 0 0ml,平均 1312ml;同期 33例未行术前栓塞脊柱肿瘤术中EBL为 15 0 0～ 5 0 0 0ml,平均 2 375ml(P <0 .0 1)。本组全部栓塞病例均无并发症。结论　脊柱肿瘤术前栓塞能显著减少术中出血 ,可使肿瘤有更多的机会获得完全切除。

Preoperative target arterial embolization for vertebral tumor

Objective To discuss the clinical value of preoperative embolization of vertebral tumors. Methods Data of 54 patients were retrospectively studied. Thirteen lesions were in the cervical, 17 in the thoracic, 15 in the lumber and 9 in the sacral regions. The vertebral tumors were embolized prior to operation with gelatin sponge particles, polyvinyl alcohol (PVA) particles or coils. Surgical operations were performed within 1-7 days after the embolization. Results Totally 79 vessels of 43 patients were embolized, which included ascending cervical artery,1;vertebral artery,1;intercostal artery,39; lumber artery,19;internal iliac artery,15 and median sacral artery,4. Intraoperative hemorrhage showed a mean value of 1312 ml with range of 300-3000 ml in patients after embolization, and a mean value of 2375 ml with range of 1500-5000ml in patients without embolization at the same period(P<0.05). None of the patients developed postembolization complications.Conclusions Embolization prior to operation can reduce intraoperative blood loss significantly and conduce the total resection.
