Mesenteric Vascular Diseases

Nonatherosclerotic obstructive vascular diseases of the mesenteric and renal arteries.

Nonatherosclerotic vascular diseases of the mesenteric and renal arteries are considered to occur less frequently than those caused by occlusive atherosclerotic disease. However, when present, they pose a significant diagnostic and therapeutic challenge. Such disorders include fibromuscular dysplasia, median arcuate ligament syndrome, the renal nutcracker syndrome, and some forms of acute and c...

Mesenteric Vascular Disease

Mesenteric Vascular Smooth Muscle

Vasodilating agents were tested on smooth-muscle strips of small arterial blood vessels of dog and rabbit skin and mesentery, and two patterns of reaction were demonstrated. The type 1 vasodilating agents, for example nicotinate, caused relaxation of contracted strips or blocked their contraction. The type 2 vasodilating compounds, histamine, choline esters, and bradykinin, either caused contra...

Mesenteric vascular disease.

Mesenteric vascular occlusion and intestinal infarction remain an unsolved problem. Among 136 patients with acute mesenteric infarction reported by Ottinger and Austen [1] from the Massachusetts General Hospital, only 8 per cent survived, dramatically demonstrating the need for improvement in diagnosis and treatment of this condition. These patients represented almost 1 in every 1,000 hospital ...

Vascular Aging and Diseases: Molecular Mechanisms and Influences

Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...
