Renal artery stenosis a minimally-invasive angioplasty with or without stenting. It is unclear if this approach yields better results than the use of medications alone. It is a relatively safe procedure. If all else fails and the kidney is thought to be worsening hypertension and revascularization with angioplasty or surgery does not work, then surgical removal of the affected kidney (nephrectomy) may significantly improve high blood pressure. Angioplasty with or without stenting is the best option for the treatment of renal artery stenosis due to fibromuscular dysplasia. Renal artery stenosis Renal artery stenosis is the narrowing of one of the renal arteries, most
Perineal artery Perineal artery The perineal artery (superficial perineal artery) arises from the internal pudendal artery, and turns upward, crossing either over or under the superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbocavernosus and ischiocavernosus muscles, both of which it supplies, and finally divides into several posterior scrotal branches which are distributed to the skin and dartos tunic of the scrotum. As it crosses the superficial transverse perineal muscle it gives off the "transverse perineal artery" which runs transversely on the cutaneous surface of the muscle, and anastomoses with the corresponding vessel
