Kidney enlargement effect of angioplasty for nonatherosclerotic renovascular disease: reversibility of ischemic kidney.

Hypertens Res 2020 May 22. Epub 2020 May 22.

Division of Nephrology, Endocrinology, and Vascular Medicine, Tohoku University Graduate School of Medicine, Sendai, Japan.

Renal artery stenosis causes kidney ischemia, reducing the size of the affected kidney, which eventually results in atrophy. Although renal atrophy is considered irreversible, resolution of the ischemia occasionally restores kidney size when the cause is renal artery stenosis. Angioplasty is effective in patients with nonatherosclerotic renovascular diseases (non-ARVDs). Read More

Using non-contrast-enhanced magnetic resonance venography for the evaluation of May-Thurner syndrome in patients with renal insufficiency: A case report.

Medicine (Baltimore) 2019 Dec;98(52):e18427

Department of Diagnostic Radiology.

Rationale: Contrast-enhanced computed tomographic venography (CTV) or magnetic resonance venography (MRV) are usually used to detect May-Thurner syndrome (MTS). However, both are associated with contrast-induced nephrotoxicity. For patients who cannot receive contrast media, non-contrast-enhanced MRV using three-dimensional (3D) turbo spin-echo (TSE) is considered an alternative. Read More

Effect of sex differences in treatment response to angioplasty in a murine arteriovenous fistula model.

Am J Physiol Renal Physiol 2020 Mar 9;318(3):F565-F575. Epub 2019 Dec 9.

Vascular and Interventional Radiology Translational Laboratory, Department of Radiology, Mayo Clinic, Rochester, Minnesota.

Failure to mature and venous neointimal hyperplasia formation are the two major causes of hemodialysis arteriovenous fistula (AVF) vascular access failure. Percutaneous transluminal angioplasty (PTA) is the firstline treatment for both of these conditions, but, clinically, women have decreased patency rates compared with men. The hypothesis to be tested in the present study was that female mice after PTA of venous areas of higher intimal thickening have increased gene expression of transforming growth factor-β1 (TGF-β1) and TGF-β receptor 1 (TGFβ-R1) accompanied with histological changes of fibrosis compared with male mice.

Hypertension 2019 12 28;74(6):1516-1523. Epub 2019 Oct 28.

Hypertension Unit, AP-HP, Hôpital Européen Georges-Pompidou, 75015, Paris, France (A.L., G.B., N.D., M.A., L.A.).

The effect of renal artery angioplasty on blood pressure in patients with true resistant hypertension and atherosclerotic renal artery stenosis has not been fully investigated due to the exclusion of these patients from most trials. In this study, we assessed the benefits of renal angioplasty on daytime ambulatory blood pressure (dABP) in this subgroup of patients. Medical records of our hypertension department were retrospectively analyzed from 2000 to 2016. Read More
