Ischaemic Ulcers Wound Care Series What is it? An ischaemic ulcer is a wound that can happen when there is poor blood flow in your legs. Who is at risk? • People with diabetes, high blood pressure or obesity. •
Smokers.
What causes it? It is caused by insuff icient blood flow to the leg due to blocked or narrowing of the arteries. The poor blood flow causes the cells to die, resulting in ulcer formation. Once an ulcer is formed, the lack of blood flow makes it harder to heal.
What are the signs? • Skin on the leg appears shiny, tight, dry and hairless. •
Dark red, yellow, gray or black sores.
How do I look after it? • Keep the wound clean and apply recommended wound dressing to prevent infection. •
Do not wear a compression stocking on your affected leg.
•
Do not apply bandage on your affected leg.
•
Do not raise the aff ected leg when sitting or lying down. This reduces blood flow to the legs.
•
Apply skin moisturiser to both feet daily.
•
Check your feet daily for any redness, swelling or bleeding.
•
Contact your doctor or podiatrist if there are signs of infection or if your condition get worse.
