An observational study in Renal Artery Stenosis, sponsored by Peking Union Medical College Hospital. Status unknown at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2022-11-02.
Sponsored by Peking Union Medical College Hospital · Observational
The clinical benefits of endovascular treatment in renal artery stenosis remain controversial. This study uses arterial spin labelling MRI and flat-panel detector parenchymal blood volume imaging to observe the change in renal perfusion after endovascular treatment in renal artery stenosis.
58 studies on the registry are indexed under Renal Artery Obstruction; 8 are open to participants now.
This study's planned enrollment of 30 is below the median of 80 across 15 observational studies indexed under Renal Artery Obstruction.

The study was conducted in renal artery stenosis patients aged 18 to 80 years with uncontrolled blood pressure or impaired renal function, who were intended for endovascular treatment. CTA, MRA, or Doppler ultrasonography were used for the assessment of the stenosis percentage of renal artery. Subjects with technical failure were excluded in order to reduce the influence of other variables.
