目的 探讨头颈部高血运肿瘤术前栓塞的作用和适应征。方法 采用经皮穿刺插管选择性全脑血管造影和颈外肿瘤供血动脉术前3～5天血管内栓塞230例,所用栓塞材料为自制明胶海绵微粒,3.6～5F造影导管,2ml注射器不断注入造影剂观察,直至肿瘤血管染色消失。结果 栓塞后肿瘤手术出血明显减少,平均每例手术输血量减少1/3。栓塞后无永久性并发症发生。结论 头颈部高血运肿瘤手术切除前均应争取全脑血管造影,肿瘤供血动脉的术前血管内栓塞可明显减少术中出血,有利于顺利全切肿瘤。
Objective To investigate the effect and indications of preoperative embolism in head and neck hypervascularization tumor. Methods Percutaneous intubation selective cerebral angiography and external carotid artery feeding artery embolism 230 cases 3 to 5 days before the embolization material used for self-gelatin sponge particles, 3.6 ~ 5F contrast catheter, 2ml syringe continuous injection Contrast agent was observed until tumor blood vessel staining disappeared. Results After the embolization of tumor surgery bleeding was significantly reduced, with an average of each case to reduce blood transfusions 1/3. No permanent complications after embolization. Conclusions All patients with head and neck hyperlipemia should undergo full cerebral angiography prior to resection of the tumor. Preoperative intravascular embolization of the artery supplying the tumor can significantly reduce intraoperative bleeding and facilitate complete and complete removal of the tumor.
