A young male suffering from renovascular hypertension was admitted. His initial arteriogram highlighted a focal stenosis of the right renal artery. His intravascular ultrasound (IVUS) revealed increasing medial layer thickness accompanied by a mixture of both high and low echoic materials in this layer. There was also mild thickening of the intimal layer. The diagnosis of medial fibroplasia and intimal fibromuscular dysplasia (FMD) was made. Balloon angioplasty decreased the volume of dysplastic tissue. The IVUS images facilitated both the initial diagnosis of focal renal arterial stenosis and the evaluation of the mechanism of dilatation by angioplasty.
一名患有肾血管性高血压的年轻男性入院。他最初的血管造影显示右肾动脉有局灶性狭窄。他的血管内超声(IVUS)显示中层厚度增加,伴有该层中高回声和低回声物质的混合。内膜层也有轻度增厚。诊断为中层纤维增生和内膜纤维肌发育不良(FMD)。球囊血管成形术减少了发育异常组织的体积。IVUS图像有助于局灶性肾动脉狭窄的初步诊断以及血管成形术扩张机制的评估。
