Ultrasound evaluation of the efficacy of angioplasty for renal artery stenosis

Inhalt:
Secondary hypertension caused by renal artery stenosis has increasingly attracted the attention of clinicians. Atherosclerosis, fibromuscular dysplasia, aortitis and other factors can lead to the occurrence of renal vascular stenosis, especially in the former. The continuous development of interventional technology has replaced traditional surgery to a certain extent, and the evaluation of efficacy requires a simple, accurate, reproducible, side-effect, relatively inexpensive means. Ultrasound is favoured by clinicians because of its convenience, accuracy, low cost and good repeatability. The unique hemodynamic parameters can directly reflect the overall perfusion state of the microcirculation, and can be dynamically monitored and analysed for treatment effect. To provide clinicians with a reliable basis for diagnosis, ultrasound has important clinical value. The main purpose of this study was to determine the assessment of color Doppler ultrasound on the effect of interventional therapy for renal artery stenosis. Comparing the data of preoperative and postoperative one month, the changes of hemodynamic parameters can reflect the changes of morphological indicators, and there is a good correlation between the two. Therefore, color Doppler ultrasound is an effective method to evaluate the efficacy of interventional procedures.
