Chronic occlusion of mesenteric vessels (abdominal toad)

Chronic occlusion of mesenteric vessels (abdominal toad) . Causes: atherosclerosis of mesenteric vessels, arteritis, fibromuscular hyperplasia of the wall or compression of the artery from the outside (legs of the diaphragm, fibers of the nerve plexuses, fibrous strands). The most frequent localization is the superior mesenteric artery. Symptoms: severe pain after 2-4 hours after eating, impaired absorption, diarrhea, vascular noise. Pain in the abdomen is usually strong, prolonged, accompanied by loss of body weight (due to impaired absorption due to hypoxic atrophy of the mucous membrane or as a result of abstinence from food due to severe pain in the abdomen). With auscultation of the abdominal cavity, stenotic vascular noises above the navel are audible. The main diagnostic method is angiography. The expressed painful syndrome serves as an indication to the operation, in the started cases there are ischemic enteritis and enterocolitis.

Treatment operative - endarterectomy or aortomethovenous shunting autovenoy.
