Elite overhead athletes are at risk of vascular injury due to repetitive abduction and external rotation of the dominant arm. The posterior circumflex humeral artery (PCHA) is prone to degeneration, aneurysm formation, and thrombosis in elite volleyball players and baseball pitchers. The prevalence of PCHA-related thromboembolic complications is unknown in this population. However, the prevalence of symptoms associated with digital ischemia is 31% in elite volleyball players. A standardized noninvasive imaging tool will aid in early detection of PCHA injury, prevention of thromboembolic complications, and measurement reproducibility. A standardized vascular sonographic protocol for assessment of the proximal PCHA (SPI-US protocol [Shoulder PCHA Pathology and Digital Ischemia-Ultrasound protocol]) is presented.
优秀的过头运动项目运动员由于优势手臂反复外展和外旋而有血管损伤的风险。在优秀排球运动员和棒球投手中，旋肱后动脉（PCHA）容易发生退变、形成动脉瘤和血栓形成。在这一人群中，与PCHA相关的血栓栓塞并发症的发生率尚不清楚。然而，在优秀排球运动员中，与手指缺血相关症状的发生率为31%。一种标准化的非侵入性成像工具将有助于早期发现PCHA损伤、预防血栓栓塞并发症以及测量的可重复性。本文介绍了一种用于评估近端PCHA的标准化血管超声检查方案（SPI-US方案[肩部PCHA病理学和手指缺血-超声方案]）。
