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
Intersegmental artery with the exception of the 5th (last) lumbar intersegmental artery, which becomes the common iliac arteries. These arteries merge into the lateral sacral artery. Intersegmental artery The intersegmental arteries are a set of 30 arteries arising from the embryonic dorsal aorta, with each artery providing blood supply to one somite and its derivatives. The cervical intersegmental arteries merge into the vertebral artery with the exception of the 7th (or possibly the 6th) cervical intersegmental artery, which becomes the subclavian artery. The confusion arises because the vertebral artery drains into the subclavian artery following the disappearance of the dorsal aortae in
