Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Perfusion of the target kidney assessed by Arterial Spin Labelling MRI		Changes from baseline renal perfusion at 2 months
Primary	Perfusion of the target kidney assessed by Flat-panel Detector Parenchymal Blood Volume Imaging		Changes from baseline renal perfusion immediately after endovascular intervention
Secondary	Blood pressure		Changes from baseline blood pressure at 1 year
Secondary	Renal function		Changes from baseline renal function at 1 year
