为了探讨治疗甲亢的新方法，在对５３条犬甲状腺动脉栓塞过程中，发现有４条犬甲状腺中静脉缺如，有５条犬有甲状腺最下动脉。甲状腺动脉栓塞后，栓塞区域内血流被完全阻断，发生缺血性无茵坏死。术后４个月栓塞区域仍可见栓塞剂存留，病理学检查有大量成纤维细胞增生和炎细胞浸润。甲状腺动脉栓塞后能永久性阻断甲状腺区域血流，栓塞区域血管不能再腔化，有效地降低了甲状腺素的分泌，为治疗甲亢选择新的方法提供了理论依据。
In order to explore a new method for the treatment of hyperthyroidism, 53 canine thyroid artery embolization process, found that 4 dogs lack the thyroid vein, 5 dogs have the thyroid artery. Thyroid artery embolization, the embolization area of blood flow is completely blocked, the occurrence of ischemic necrosis. Embolism was still seen in the embolized area 4 months after operation. There were a large number of fibroblast proliferation and inflammatory cell infiltration in the pathological examination. Thyroid artery embolization can permanently block the thyroid blood flow, embolization area can no longer cavities, effectively reducing the secretion of thyroxine, for the treatment of hyperthyroidism to choose a new method provides a theoretical basis.
