目的探讨甲状腺动脉的解剖及影像学表现,以提高介入栓塞治疗Graves病的疗效,降低并发症。方法对16具成人尸体(尸体组)甲状腺动脉进行解剖研究,并对8例甲状腺功能正常(正常组)及17例Graves病患者(甲亢组)的甲状腺动脉造影片进行影像学研究。结果甲状腺动脉发出较多非腺体支。尸体组与正常组各指标差异无统计学意义,但甲亢组甲状腺动脉延长,主干及腺体干支内径明显增粗,甲状腺动脉与颈动脉的角度增大,与前两组比较差异有统计学意义。腺体支之间的吻合和腺体内外的危险吻合支丰富。结论Graves病甲状腺动脉改变有利于进行介入栓塞。避开非腺体支和危险吻合支是降低介入栓塞并发症的关键。
Objective To investigate the anatomy and imaging findings of thyroid artery in order to improve the curative effect of interventional embolization on Graves’ disease and reduce the complications. Methods Twenty-six thyroid arteries of adult cadavers (corpse group) were dissected and the images of thyroid arteriography in 8 cases of thyroid function (normal group) and 17 Graves’ disease (hyperthyroidism group) were studied. Results Thyroid artery issued more non-glandular branch. There were no significant differences in the indexes between the cadaver group and the normal group, but the thyroid artery in the hyperthyroidism group was prolonged, the diameter of stem and branch in the trunk and gland was significantly thicker, and the angle between the thyroid artery and carotid artery was increased, which was significantly different from the former two groups . Anastomosis between the glandular branches and glands in the anastomosis with the risk of rich. Conclusion Graves disease thyroid artery changes in favor of interventional embolization. Avoiding non-glandular branches and dangerous anastomosis branches is the key to reducing the complications involved in embolization.
