The variations of vessels arising from the aortic arch are numerous. The purpose of this study is the description of the variations on the branching pattern of arch of aorta, in order to offer useful data to anatomists, radiologists, vascular surgeons, neck and thorax surgeons in Nepalese subjects, and relating it with embryological basis. In this investigation, branching patterns of arch of aorta were studied in 85 cases of Nepali origin. Variations in the anatomical arrangements of the branches of arch of aorta in the Nepali population were as par with other populations of the world. Variations on the branching pattern of the arch of aorta were found in 17 cadavers (20.0%) of elderly Nepalese. The accurate information on this is vital for vascular surgery in the thorax, head and neck regions. Although, the variations are usually asymptomatic, they may cause dyspnea, dysphagia, intermittent claudication, misinterpretation ofradiological examinations and complications during neck and thorax surgery. These observations are precious while invading the arch of aorta and its branches by instruments, as all areas are susceptible to surgical attack.
源自主动脉弓的血管变异众多。本研究的目的是描述主动脉弓分支模式的变异，以便为尼泊尔受试者的解剖学家、放射科医生、血管外科医生、头颈外科医生和胸外科医生提供有用数据，并将其与胚胎学基础相关联。在本次调查中，对85例尼泊尔裔个体的主动脉弓分支模式进行了研究。尼泊尔人群中主动脉弓分支的解剖学排列变异与世界其他人群相当。在17具老年尼泊尔人尸体（20.0%）中发现了主动脉弓分支模式的变异。关于这方面的准确信息对于胸、头颈部区域的血管手术至关重要。虽然这些变异通常无症状，但它们可能导致呼吸困难、吞咽困难、间歇性跛行、放射学检查误诊以及头颈和胸外科手术期间的并发症。在通过器械侵入主动脉弓及其分支时，这些观察结果非常宝贵，因为所有区域都易受手术侵袭。
