摘要目的确定优秀排球运动员旋肱后动脉(PCHA)动脉瘤的流行病学以及旋肱后动脉和肱深动脉(DBA)的血管特征。方法 280位运动员接受了优势臂血管超声检查的标准化评估。评估内容包括PCHA动脉瘤的直径(血管矢状径增宽超过150%为动脉瘤)、PCHA和DBA的解剖、分支情况及其走行和直径。结果超声检查中,PCHA和DBA分别有100%和93%(260/280)可被识别。PCHA动脉瘤的患病率为4.6%(13/280)。所有动脉瘤都发生于起自腋动脉(AA)的PCHA的近心端。81%(228/280)的受检者PCHA起自AA,其中
Abstract Objective To determine the epidemiology of posterior humeral brachial artery (PCHA) aneurysms and the vascular characteristics of the superior brachial artery and the brachial artery (DBA) in elite volleyball athletes. Methods 280 athletes underwent a standardized assessment of superior arm vascular ultrasound. Assessments included the diameter of the PCHA aneurysm (more than 150% of vessel sagittal enlargement was aneurysm), the anatomy and branching of PCHA and DBA, and their course and diameter. Results In sonography, PCHA and DBA were identified as 100% and 93% (260/280), respectively. The prevalence of PCHA aneurysms was 4.6% (13/280). All aneurysms occur proximal to the PCHA originating from the axillary artery (AA). 81% (228/280) of the subjects PCHA from AA, among them
