**4.2 Arterial ulcers**

Arterial ulcers are rare when compared to venous ones. The consequence of arterial insufficiency, which is caused by atherosclerosis or rarely thromboembolic or radiation damage, gives rise to arterial ulcers. When the arterial lumen narrows down, it reduces perfusion, which leads to ischemia and hypoxia [18]. Peripheral vascular disease is defined as the blockage of arteries other than those supplying blood to the heart and brain. An increase in age, hypertension, diabetes, smoking, and hypercholesterolemia are the significant risk factors for these ulcers. The management of risk factors and reconstructive surgery or angioplasty to restore the peripheral flow is a part of wound therapy. These ulcers usually occur distally over bony prominences and are present with a round and the sharply demarcated border [20]. **Figure 11** is an image representing an arterial ulcer.
