The arteria lusoria is an aberrant right subclavian artery that passes dorsally between the esophagus and spine after branching off from the aortic arch. The role of endoscopic ultrasonography (EUS) in the diagnosis of the arteria lusoria has not been established. The possibility of demonstrating this vascular anomaly with EUS and estimating its prevalence was assessed.
From December 1991 to September 1998, EUS of the upper gastrointestinal tract was performed in 3334 consecutive patients for various reasons. After imaging of the target organ(s), the echoendoscope was slowly pulled back while imaging the mediastinum proximally to the superior aspect of the aortic arch. In every patient, the area of the aortic arch was carefully inspected and special attention was given to vessels crossing from left to right between the esophagus and spine.
During the study period, an arteria lusoria was discovered in 12 of 3334 patients (0.36%: 95% CI [0.16%, 0.56%]). There were 6 men and 6 women; mean age was 64+/-14.7 years. In all 12 patients the arteria lusoria passed between the esophagus and spine. In none of the patients could symptoms be attributed to the presence of this anatomic variant.
An arteria lusoria can be detected with upper gastrointestinal EUS and was found in 0.36% of patients. EUS can accurately demonstrate this vascular anomaly.
迷走右锁骨下动脉是一种异常的右锁骨下动脉，它在从主动脉弓分支后，于食管和脊柱之间向后走行。内镜超声检查（EUS）在迷走右锁骨下动脉诊断中的作用尚未确立。本研究评估了用EUS显示这种血管异常及其患病率的可能性。
1991年12月至1998年9月，因各种原因对3334例连续患者进行了上消化道EUS检查。在对目标器官成像后，将超声内镜缓慢回撤，同时对主动脉弓上方的纵隔进行近端成像。对每例患者，仔细检查主动脉弓区域，特别注意食管和脊柱之间从左向右走行的血管。
在研究期间，3334例患者中有12例发现迷走右锁骨下动脉（0.36%：95%可信区间[0.16%，0.56%]）。男性6例，女性6例；平均年龄64±14.7岁。所有12例患者的迷走右锁骨下动脉均走行于食管和脊柱之间。所有患者的症状均不能归因于这种解剖变异的存在。
上消化道EUS可检测到迷走右锁骨下动脉，在0.36%的患者中发现该动脉。EUS能准确显示这种血管异常。
