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.

Basilar artery Basilar artery In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood. The two vertebral arteries and the basilar artery are sometimes together called the "vertebrobasilar system", which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of Willis from the internal carotid arteries. The basilar artery arises from the confluence of the two vertebral arteries at the junction between the medulla oblongata and the pons between the VIth cranial nerves. It ascends superiorly in the basilar sulcus
