Entrapment of renal artery by the diaphragmatic crus is a rare cause of renal artery stenosis. Spiral computed tomography angiography provides a definitive diagnosis and shows the precise relationship of the artery to the diaphragmatic crus. The authors present a case of hypertension developing in a young 20-year-old female due to entrapment of the left renal artery by the diaphragmatic crus. This condition should be considered in young hypertensive patients with renal artery stenosis without cardiovascular risk factors.
膈脚压迫肾动脉是肾动脉狭窄的罕见原因。螺旋计算机断层血管造影可提供明确诊断，并显示该动脉与膈脚的确切关系。作者报告了一例20岁年轻女性因膈脚压迫左肾动脉而发生高血压的病例。对于无心血管危险因素的肾动脉狭窄的年轻高血压患者，应考虑这种情况。
