Clinical Wound Specialists,
1-Ischemic ulcer or arterial ulcer occurs when the artery is blocked (Anthony, 2018). Arteries carry oxygenated blood to the tissue and If this artery is blocked, then the supply of oxygen and nutrients to that body part or tissue will be deprived. Finally, this tissue dies and develop to an ulcer. Some potential causes of the arterial ulcer are diabetes, smoking and atherosclerosis whereas venous ulcer is caused by damage to the vein and when a vein is damaged there is deficiency blood flow to the heart and this can result in accumulation of blood in one body part and results in fluid shift to cause edema (Caprini, Partsch, & Simman, 2013). Then this edema halts circulation and eventually the tissue dies to cause an ulcer. Some potential causes are varicose veins, DVT.
Another difference is based on their symptoms. Arterial ulcer has a symptom of pain at night, feeling cold to touch due to poor circulation, deep wound where, as venous ulcer has a sign of swelling, aching or flaking sensation on the body part. Most of the time both tend to affect the extremity but are not restricted to any part of the body (Anthony, 2018).
