导管血管成形术或血管造影术经桡动脉远端接入点（dRA），位于解剖鼻烟盒，是一种侵入性较小的冠状动脉介入治疗策略，引起了广泛关注。确定dRA的直径是必要的，以尽量减少动脉闭塞的风险，并安全地进行导管介入。这是一项回顾性观察性研究，包括2018年2月至2018年8月期间在日本青森青森共立医院接受冠状动脉造影或冠状动脉介入治疗的患者。在血管造影或介入手术前，使用超声测量患者腕部桡动脉（cRA）的直径和常规接入点。总共分析了120例患者。男性患者cRA和dRA直径分别为2.62 +/- 0.60 mm和2.04 +/- 0.43 mm。雌虫直径分别为2.44 +/- 0.51 mm和1.96 +/- 0.44 mm。总体而言，dRA在统计学上显著小于cRA。然而，观察到差异，8例（6.7%）患者的dRA大于cRA。dRA的直径仅表示cRA的直径。一项多变量分析没有揭示与血管直径相关的因素。dRA的大小和解剖结构差异很大。因此，很难预测动脉的实际直径。定制选择鞘的大小和介入的位置对于每个患者在插管前安全地进行超声检查是必不可少的。
Catheter angioplasty or angiography via the distal access point of the radial artery (dRA), located at the anatomical snuff box, is a less invasive strategy for coronary intervention attracting considerable attention. Determining the diameter of the dRA is necessary to minimize the risk of artery occlusion and safely perform catheter intervention. This was a retrospective observational study including patients who underwent coronary angiography or coronary intervention at Aomori Kyoritsu Hospital, Aomori, Japan, between February 2018 and August 2018. The diameter of the dRA and the conventional access point of the radial artery (cRA) at the wrist of the patients were measured using ultrasound prior to angiography or interventional procedure. A total of 120 patients were analyzed. In male patients, the diameters of the cRA and dRA were 2.62 +/- 0.60 mm and 2.04 +/- 0.43 mm, respectively. In females, these diameters were 2.44 +/- 0.51 mm and 1.96 +/- 0.44 mm, respectively. Overall, the dRA was statistically significantly smaller than the cRA. However, variations were observed, with eight patients (6.7%) having a larger dRA than cRA. The diameter of the dRA indicated only that of the cRA. A multivariate analysis did not reveal factors associated with vessel diameter. The size and anatomy of the dRA varied considerably. Thus, it is difficult to predict the actual diameter of the artery. Customized selection of the size of the sheath and site of intervention is essential for each patient to safely perform ultrasound examination prior to cannulation.
