【摘要】 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。更多还原

【Abstract】 Objective To explore the anatomy and imaging manifestations of thyroid arteries for improving the efficiency and lowering the complication in interventional embolization of Graves’ disease. Methods Thyroid arteries were investigated, including 16 adult cadavers(Cadaver group), 8 non-thyropathic patients(Normal group)and 17 Graves patients(Graves group). The inner diameters of the trunk and supplying branches of thyroid artery, the angles between the origination of branches and the beginning of the trunk, and the angles between the trunk of thyroid artery and carotid or subclavian artery were measured. In addition, data of the three groups were statistically analyzed. Results Many non-thyroid arterial branches arose from thyroid artery, with no statistical difference in their indexes between Cadaver group and Normal group. The thyroid arteries showed much longer, obviously wider in diameter, and larger angles between the trunk of thyroid artery and carotid artery in Graves group than those of Cadaver group and Normal group; outcoming with significant statistical differences; and furthermore, with increase of interglandular branches and dangerous internal and external anastomoses. Conclusions The specific thyroid arterial changes of Graves’ disease are helpful for the interventional embolization. Non-thyroid branches and dangerous anastomoses should not be embolized as far as possible, for decreasing the complications of the interventional procedure for Graves’ disease.更多还原
