Arterial denervation can be understood as the artificial deprivation of a tissue or organ of innervation from one or another branch of the autonomic nervous system. In a general sense, this means removing the nerve endings from the part of the body that receives the blood supply from that artery. For percutaneous methods, the term “embolization” is also used. Artery embolization is a sclerotherapy technique using microcoils or embolization formulas in a specific area of the artery (arteries) that has vascular problems (atherosclerosis) and tissue nutritional disorders. In simple words, vascular stenoses help to widen the artery. It has been proven that sympathectomy reduces the manifestations of arterial hypertension in patients with fibromuscular stenosis of the renal arteries. Experiments with kainin and sympathomimetic stimulation of intact and postsypathotomized forearms, as well as histological observations, allow us to conclude that new systemic reactions occur after denervation of the splanchnic nerve (medial part) or subcostal arteries in a sick person.
