目的通过计算机断层扫描血管造影评估上肢和掌浅弓动脉系统的异常和变异，并指导临床医生进行手术。对78例156个上肢患者进行计算机断层血管造影回顾性分析。该研究得到了医院当地伦理委员会的批准。通过对计算机断层扫描血管造影图像的分析，记录了以下信息；双上肢桡动脉、尺动脉和肱动脉的直径和异常情况，这些动脉是否存在动脉粥样硬化变化或狭窄，掌浅弓是否完整，以及动脉优势。并对掌浅弓分布和解剖结构进行计算机断层扫描血管造影分类。病例的桡动脉、尺动脉和肱动脉的平均基线直径为：分别为 2.8 +/- 0.6、2.5 +/- 0.7 和 4.7 +/- 0.6 毫米。 69.2% 的右手和 70.5% 的左手观察到完整的浅掌弓。对于右侧掌浅弓，桡动脉占优势的有 2 个，尺动脉占优势的有 47 个，其余呈共显性。左侧一只手桡动脉占优势，尺动脉占优势49例，共优势28例。在浅表掌弓分类中，其中四个掌弓 (A-D) 被定义为完整，其余三个 (E-G) 被定义为不完整。当前的研究阐明了掌循环和前臂动脉的不同变化，以帮助外科医生进行经桡动脉或经尺动脉插管、血液透析或冠状动脉旁路移植术。
To evaluate the abnormalities and variations of the arterial system of upper extremities and superficial palmar arch with computed tomography angiography and to guide the clinician during this procedure.A total of 156 upper extremities of 78 cases were retrospectively analyzed using computed tomography angiography. The study was approved by the local ethics committee of the hospital. From the analysis of the computed tomography angiography images, the following information was recorded; the diameters and abnormalities of radial, ulnar and brachial arteries in both upper extremities, the presence of atherosclerotic changes or stenosis in these arteries, whether the superficial palmar arch was complete or incomplete, and arterial dominance. Also, the computed tomography angiography classification of superficial palmar arch distribution and anatomic configuration was performed.The mean baseline diameters of the radial, ulnar and brachial arteries of the cases were; 2.8 +/- 0.6, 2.5 +/- 0.7, and 4.7 +/- 0.6 mm, respectively. A complete superficial palmar arch was observed in 69.2 % of the right hands and 70.5 % of the left hands. For the superficial palmar arches on the right side, the radial artery was dominant in two and the ulnar artery was dominant in 47 with the remaining showing codominance. On the left side, the radial artery was dominant in one hand, with the ulnar artery being dominant in 49 cases, and in 28 cases, there was codominance. In the superficial palmar arch classification, four of the arches (A-D) were defined as complete and the remaining three (E-G) as incomplete.The current study clarified different variations in palmar circulation and forearm arteries to aid the surgeon during trans-radial or trans-ulnar catheterization, hemodialysis, or coronary artery bypass grafting.
