一名35岁男性前往他的初级保健医生那里,以评估之前未知的无症状高血压。左臂血压为146/89毫米汞柱,右臂血压为146/99毫米汞柱,左腿血压为104/83毫米汞柱,右腿血压为109/90毫米汞柱。胸部的X射线如图所示。以下哪项发现不是这种状况的典型表现?
A. Collateral arterial circulation侧支动脉循环
B. Continuous murmur连续低语
C. Left ventricular hypertrophy左心室肥厚
D. Radial-femoral delay桡骨-股骨延迟
E. Rib notching肋骨切口
答案解析:
正确的答案是连续低语。该患者被诊断为降主动脉缩窄。患者被发现有广泛的侧支动脉循环造成的肋骨切迹、左心室肥厚和桡动脉-股动脉延迟。经皮主动脉缩窄支架置入术无并发症发生。1个月随访时,患者血压有所改善。3个月随访时复查,侧支循环明显减少。
正确答案:B
