A venous ulcer tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A venous ulcer is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.
Venous ulcers are common and very difficult to treat. Chronic venous ulcers are painful and debilitating. Even with treatment, recurrences are common if venous hypertension persists. Nearly 60% develop phlebitis which often progresses to deep vein thrombosis in more than 50% of patients. The venous insufficiency can also lead to severe hemorrhage.
Chronic wound pain is a condition described as unremitting, disabling, and recalcitrant pain experienced by individuals with various types of chronic wounds. [1] Chronic wounds such as venous leg ulcers, arterial ulcers, diabetic foot ulcers, pressure ulcers, and malignant wounds can have an enormous impact on an individual’s quality of life with pain being one of the most distressing symptoms.
This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage [7] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration.
Venous insufficiency is the most common disorder of the venous system, and is usually manifested as either spider veins or varicose veins. Several treatments are available including endovenous thermal ablation (using radiofrequency or laser energy), vein stripping, ambulatory phlebectomy, foam sclerotherapy, laser, or compression.

Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds [2] and mostly affect the elderly. They are thought to be due to venous hypertension caused by improper function of valves that exist in the veins to prevent blood from flowing backward.
It can result in varicose veins and, in severe cases, in venous ulcer. The reversed blood pools in the low third of legs and feet. [17] Unlike in the arterial ultrasound study, when the sonographer studies venous insufficiency, the vein wall itself has no relevance and attention is focused on the direction of blood flow. The objective of the ...
Pressure ulcer [22] – Also known as decubitus ulcers or bedsores, this type of wound is a result of chronic pressure to the skin over a prolonged period. While most individuals have intact sensation and motor function which allow for frequent positional change to prevent the formation of such ulcers, older individuals are particularly ...
