Variations in the branching pattern of the Arch of Aorta (AoA) are common in patients undergoing contrast-enhanced Multidetector Computed Tomography, the identification of which is crucial in managing patients undergoing cardiovascular/neck surgeries and interventions.
This prospective cross-sectional study involved 513 patients who were sent to the Department of Radiology for evaluation of various pathologies of chest and neck between August 2018 and July 2019. After approval from the Institutional Review Committee {Reference No: 11(6-11) E2/075/076}, contrast-enhanced computed tomography images were evaluated with variations in branches of the left-sided arch of the aorta and symptoms associated.
Variations in branches of the arch of aorta were seen in 69 (13.45%; 95% CI: 10.60%-16.71%) of cases, left common carotid artery and brachiocephalic trunk having common origin or common trunk was 51(9.94%). The mean age was 52.4±20 years (Range 3 months to 92 years) with male to female ratio of 1.3:1.
Contrast-enhanced computed tomography is the modality of choice for the detection of the variations in branches of AoA, recognition of which is crucial in vascular intervention and surgical procedures to reduce the postoperative morbidity and mortality of the patients.
在接受对比增强型多排计算机断层扫描的患者中，主动脉弓（AoA）分支模式的变异很常见，识别这些变异对于管理接受心血管/颈部手术和介入治疗的患者至关重要。
这项前瞻性横断面研究纳入了2018年8月至2019年7月期间被送往放射科评估胸部和颈部各种病变的513例患者。经机构审查委员会批准（参考编号：11(6 - 11)E2/075/076）后，对对比增强计算机断层扫描图像进行评估，观察主动脉左侧弓分支的变异情况及相关症状。
69例（13.45%；95%可信区间：10.60% - 16.71%）出现主动脉弓分支变异，其中左颈总动脉和头臂干有共同起源或共同干的情况有51例（9.94%）。平均年龄为52.4±20岁（范围3个月至92岁），男女比例为1.3:1。
对比增强计算机断层扫描是检测主动脉弓分支变异的首选方式，识别这些变异对于血管介入和外科手术至关重要，可降低患者术后的发病率和死亡率。
