Venous ulcers
Venous Ulcers
Venous ulcers, also known as venous insufficiency ulcers, stasis ulcers, or varicose ulcers, are wounds that occur due to improper functioning of the venous system in the legs. They are the major cause of chronic wounds, occurring in 70% to 90% of leg ulcer cases.
Pronunciation
Venous ulcers are pronounced as /ˈviːnəs ˈʌlsər/.
Etymology
The term "venous" is derived from the Latin word "vena", meaning "vein". The term "ulcer" comes from the Latin "ulcus", which means "sore".
Definition
Venous ulcers are open sores in the skin that are caused by an abnormality or damage to the veins. This usually occurs in the legs, particularly in the area just above the ankle. They can be painful and may take several weeks or even months to heal.
Causes
Venous ulcers are caused by venous insufficiency, a condition where the flow of blood through the veins is inadequate, causing blood to pool in the legs. This can be due to a number of factors, including deep vein thrombosis, varicose veins, and phlebitis.
Symptoms
Symptoms of venous ulcers include pain, swelling, and discoloration in the affected area. The skin around the ulcer may be shiny, tight, and may appear darker than normal. The ulcer itself may have a red or yellowish color and may produce a foul-smelling discharge.
Treatment
Treatment for venous ulcers typically involves measures to improve blood flow in the legs, such as compression therapy, leg elevation, and exercise. In some cases, medication or surgery may be required.
