摘要
目的评估骶骨肿瘤供血动脉的来源及术前栓塞的价值。方法对42例骶骨肿瘤手术切除前24 h内以明胶海绵颗粒对供血动脉进行栓塞。肿瘤包括脊索瘤14例、神经鞘瘤8例、转移瘤7例、骨软骨肉瘤3例、骨肉瘤1例、骨巨细胞瘤5例、成血管细胞瘤1例、多发性骨髓瘤1例、血管肉瘤1例、成软骨细胞瘤1例。结果根据骶骨肿瘤的位置及大小不同,供血动脉来源不一致。42例造影提示肿瘤供血动脉有98支,其中右腰2动脉1支、左腰3动脉1支、右腰3动脉3支、左腰4动脉6支、右腰4动脉8支、左腰5动脉1支、左骶外侧动脉9支、右骶外侧动脉11支、左髂腰动脉1支、右髂腰动脉6支、骶正中动脉1支、左臀上动脉10支、右臀上动脉8支、左臀下动脉10支、右臀下动脉8支、左阴部内动脉8支、右阴部内动脉6支。肿瘤染色均较术前减少75%以上,栓塞24 h内行肿瘤切除术,术中、术后24 h内出血量40~7 200 m L,平均(1 255.2±982.1)m L。所有肿瘤均顺利切除,无严重并发症。结论骶骨肿瘤血供来源复杂,术前充分栓塞供血动脉能有效减少术中出血,降低手术危险性,提高肿瘤手术切除率。
Objective To investigate the origins of tumor-feeding arteries of sacral tumors and to assess the clinical value of preoperative embolization of sacral tumor before surgical resection. Methods Percutaneous transcatheter embolization of tumor-feeding arteries with gelfoam particles was performed in 42 patients with sacral tumor 24 hours before its surgical resection. The lesions included chordoma(n =14),neurilemmoma(n=8), metastatic tumor(n=7), chondrosarcoma(n=3), osteosarcoma(n=1), giant cell tumor of bone(n=5), hemangioblastoma(n=1), multiple myeloma(n=1), angiosarcoma(n=1) and chondroblastoma(n=1). Results Depending on tumor's location and size, the origins of tumor-feeding artery of sacral tumors were different from one to another. Angiography of the 42 patients showed that a total of 98 tumor-feeding arteries were detected, including right second lumbar artery(n=1), left third lumbar artery(n=1), right third lumbar artery(n=3), left fourth lumbar artery(n=6), right fourth lumbar artery(n=8), left fifth lumbar artery(n=1), left lateral sacral artery(n=9), right lateral sacral artery(n=11), left ilio-lumbar artery(n=1), right ilio-lumbar artery(n=6), median sacral artery(n=1), left superior gluteal artery(n=10), right superior gluteal artery(n =8), left inferior gluteal artery(n =10), right inferior gluteal artery(n =8), left internal pudendal artery(n =8), and right internal pudendal artery(n =6). After embolization therapy, the tumor staining markedly decreased by more than 75% when compared with the pre-embolization angiographic manifestations. Surgical resection of sacral tumor was carried out within 24 hours after embolization. The amount of blood loss in operation and within 24 hours after surgery was(40-7 200) m L, with a mean of(1 255.2±982.1) m L. The tumor was successfully removed in all patients, and no serious complications occurred.Conclusion The origin of blood supply for sacral tumors is very complex. Sufficient embolization of tumor-feeding artery of sacral neoplasm before surgical resection can effectively reduce the amount of intraoperative blood loss, reduce the risk of operation and improve the resection rate of tumor.
