目的：研究和评估无水酒精超选择栓塞骨肿瘤的价值作用，方法：对４２例诊断明确，较大或血管丰富的骨肿瘤进行超选择性瘤血管无水酒精栓塞，其中手术２７例，并进行临床病理组织学观察。结果：（１）栓塞后初期，３３例栓塞综合症较明显，２周后３２例临床症状消失或明显减轻，２６例瘤体明显缩小，质地变硬，术中出血减少及增厚的假包膜，有利于手术开展。（２）大切片观察有２３例瘤体大部分坏死，１８例瘤体内纤维小血管组织增生显著。结论：超选择瘤血管无水酒精栓塞是某些骨肿瘤重要有效的辅助治疗方法。
OBJECTIVE: To study and evaluate the value of alcohol-free superselective embolization of bone tumors. Methods: Forty-two patients with well-diagnosed, larger or well-vesseled bone tumors were subjected to superselective tumor-vessel alcohol embolization, of which 27 were operated. Perform clinical pathological histological observations. Results: (1) In the initial stage after embolization, 33 embolism syndromes were more obvious. After 2 weeks, 32 cases of clinical symptoms disappeared or significantly relieved. 26 cases of tumors were significantly reduced, texture hardened, intraoperative bleeding was reduced and thickening of the false bags. The membrane is conducive to the operation. (2) There were 23 cases of necrosis of large tumors observed in large sections, and the proliferation of fibrovascular tissue in the tumors was significant in 18 cases. Conclusion: Superselective neovascular anesthesia is an important and effective adjuvant therapy for some bone tumors.
