thinning of blood vessel walls
Introduction
Introduction Capillary is the blood vessel with the smallest diameter and the widest distribution. They branch and fit into each other. The degree of density of capillary networks in various organs and tissues varies greatly. Metabolic tissues and organs such as skeletal muscle, heart muscle, lung, kidney and many glands have dense capillary networks; tissues with lower metabolism such as bone, For muscle tendons and ligaments, the capillary network is sparse.
Cause
Cause
Causes of thinning of blood vessel wall
Long-term high blood pressure and atherosclerosis make the aortic intima become very brittle, and there is a dissection. After the blood enters the dissection, the integrity of the blood vessel is broken, and the entire blood vessel wall becomes very thin. Once it can not withstand high speed and high pressure. The blood flow, the blood vessels will rupture.

Examination and diagnosis of thinning of blood vessel wall
The diagnosis is mainly based on clinical symptoms, and some imaging examinations, such as X-ray photography of the pelvis (post-production), ultrasound examination (pregnancy), or MRI scan, pubic pain can be used as an auxiliary. Diagnostic tool.

Symptoms of vascular wall thinning
The congenital malformation of the capillaries, ie the congenital capillary wall, is so weak that it cannot contract. The disease occurs mostly at the time of birth or shortly after birth on the face, neck and back of the pillow, and in the scalp. Can be unilateral, scatter, or both sides, multiple. Initially on the skin or mucous membrane, there is a different size, light red or dark red, or purple red skin lesions, from the tip of the needle to a limb or half of the trunk, the color is deepened after crying, the boundary is clear, the shape is different, not high The skin is locally high, and after compression, part or all of it fades and the surface is smooth. With age, children or young adults may have symptoms or nodular lesions on them, most of which occur in the calves and feet, which can be painful purple-blue nodules and plaques, which can still be broken.
