What Is a Collapsed Vein?

Reduced blood volume, shock, dehydration, high fever, sweating, foam sclerosing agents, etc. can cause vein collapse.

Vein collapse

Vein collapse is a symptom of abnormal shrinkage of veins that becomes distorted and sunken. Reduced blood volume, shock, dehydration, high fever, sweating, foam sclerosing agents, etc. can cause vein collapse.

Reduced blood volume, shock, dehydration, high fever, sweating, foam sclerosing agents, etc. can cause vein collapse.
Insufficient patients due to the decrease in circulating blood volume, peripheral blood vessels collapse, flat, poor elasticity, and are in the shape of a strand, the superficial veins disappear, which brings some difficulties to venipuncture.
The sclerosing agent causes an inflammatory response to the wall of the vein. The vein is collapsed by continuous pressure, and granulation tissue and subsequent fibrosis grow in the collapsed vein cavity. Finally, a fibrous cord is formed to permanently occlude the vein cavity.
Common signs of isotonic dehydration are poor skin elasticity, dry skin and mucous membranes, fast and weak pulses, superficial vein collapse, cold limbs, and decreased urine output.
Differential diagnosis of venous collapse:
Varicose veins: It is a symptom of abnormal expansion of the veins that becomes distorted and swollen. About 50% of the population over the age of 40 has an incidence rate. Especially women, about 2/3 of them have varicose veins of varying degrees. This deformed and sometimes quite painful disease usually occurs in the legs and is caused by the pressure placed on your leg veins by your upright posture. Varicose veins usually do not bring serious consequences, but it is possible that foramen veins, under the dual effects of gravity and valve failure, can greatly reduce the blood supply to the tissues, causing malnutrition and skin ulcers.

Transfusion of blood and replenishment of fluids in a timely manner, and timely delivery of medical treatment for shock.
