Refractory hypertension caused by bilateral renal artery stenosis: a case report and literature review
-
摘要: 由双侧肾动脉狭窄(RAS)所致的难治性高血压,发病率较低,临床诊治较为困难。首都医科大学宣武医院全科医学科收治1例48岁男性患者,近期出现严重的高血压病史。考虑患者的年龄及高血压的严重程度,笔者筛查了继发性高血压的常见原因,进一步行腹主动脉CT血管成像,提示双侧肾动脉开口处中-重度狭窄,为双侧肾动脉狭窄导致的难治性高血压。联合血管外科分期实施双侧肾动脉支架植入术,术后随访患者血压逐渐控制稳定。本文对该患者具体诊治经过进行回顾性分析,并复习相关文献。Abstract: Refractory hypertension caused by bilateral renal artery stenosis (RAS) has a low incidence and is difficult to diagnose and treat clinically. The Department of General Medicine of Xuanwu Hospital Capital Medical University admitted a 48-year-old male patient with a recent history of severe hypertension. Considering the patient's age and severity of hypertension, we screened for common causes of secondary hypertension. Further abdominal aortic CTangiography showed moderate to severe stenosis at the openings of the bilateral renal arteries, which led to refractory hypertension. Therefore, angioplasty of both renal arteries was performed as a staged procedure, and the patient's blood pressure was gradually controlled and stabilized during postoperative follow-up. This article reviews the specific diagnosis and treatment process and reviews relevant literature.
