To describe a case of renal artery stenosis with fibromuscular dysplasia (FMD) and extensive iatrogenic dissection treated with Wallstent implantation.
An 83-year-old woman with a history of coronary artery disease and hypertension presented at another facility with exertional angina and poorly controlled hypertension. Renal arteriography uncovered a critical right renal artery stenosis with severe FMD. However, angioplasty resulted in extensive dissection of the renal artery, for which the patient was referred to our institution. The renal artery was recanalized via the left brachial approach with restoration of flow using a Wallstent and a Palmaz stent. The patient's blood pressure was controllable after this procedure, and follow-up duplex imaging with flow velocities at 6 months showed patent right renal artery stents.
Owing to its length and flexibility, the Wallstent endoprosthesis was a useful treatment modality in this case of extensive renal artery dissection.
描述一例患有纤维肌性发育异常（FMD）的肾动脉狭窄并伴有广泛医源性夹层形成，采用Wallstent支架植入术治疗的病例。
一名83岁有冠状动脉疾病和高血压病史的女性患者，在另一家医疗机构因劳力性心绞痛和血压控制不佳就诊。肾动脉造影发现右侧肾动脉严重狭窄并伴有严重的纤维肌性发育异常。然而，血管成形术导致肾动脉广泛夹层形成，该患者遂转诊至我院。通过左肱动脉途径使肾动脉再通，使用Wallstent支架和Palmaz支架恢复血流。术后患者血压可控，6个月时的随访双功成像显示右侧肾动脉支架通畅。
由于其长度和柔韧性，Wallstent腔内假体在该例广泛肾动脉夹层病例中是一种有效的治疗方式。
