Thyroidea ima artery is a variant arterial branch of arch of aorta supplying the thyroid gland. Understanding the anatomic variances and correctly identifying the thyroidea ima artery is crucial to preventing serious complications both before and after neck surgery. The aim of this study was to find out the prevalence of thyroidea ima artery in cadavers of a medical college in Nepal.
A descriptive cross-sectional study was carried out at the department of anatomy in Janaki Medical College, Dhanusha, Nepal from 27 December 2022 to 30 June 2023 after ethical clearence from the same institution. Origin of thyroidea ima artery was observed, recorded and photographed. Convenience sampling method was used. Data was analyzed using Microsoft Excel.
Out of 35 cadavers, thyroidea ima artery was present in 2 (5.71%), arising from brachiocephalic trunk just proximal to its bifurcation and there was absence of inferior thyroid artery.
Findings from our study showed that thyroidea ima artery originated from brachiocephalic trunk with absence of inferior thyroid artery.
甲状腺最下动脉是主动脉弓的一个变异动脉分支，为甲状腺供血。了解解剖变异并正确识别甲状腺最下动脉对于预防颈部手术前后的严重并发症至关重要。本研究的目的是查明尼泊尔一所医学院尸体中甲状腺最下动脉的发生率。
2022年12月27日至2023年6月30日，在尼泊尔达努沙贾纳基医学院解剖学系进行了一项描述性横断面研究，研究获得了该机构的伦理批准。观察、记录并拍摄了甲状腺最下动脉的起源。采用方便抽样法。数据使用Microsoft Excel进行分析。
在35具尸体中，有2具（5.71%）存在甲状腺最下动脉，其起源于头臂干分叉近端，且无甲状腺下动脉。
我们的研究结果表明，甲状腺最下动脉起源于头臂干，且无甲状腺下动脉。
