Welcome to the vascular department. If you’re reading this, you or a loved one may have been diagnosed with poor blood flow to the foot so called ischemic foot. This information aims to provide comprehensive information about this condition and guide you through its management.
What is Ischemic Foot?
Ischemic foot refers to a lack or reduction of blood supply to the foot, often due to blockages in the arteries. Reduced blood flow can lead to pain, wounds that don’t heal, or tissue damage.
Causes of Ischemic Foot:
- Peripheral Arterial Disease (PAD)
- Blood clots
- Diabetes
- Smoking
- High blood pressure and cholesterol
Symptoms to Watch For:
- Pain or cramping in the feet, calves, or thighs, especially during activity
- Cold feet
- Color changes in the skin of the foot e.g. gangrene
- Non-healing sores or ulcers
- Loss of hair on the feet and legs

Diagnosis:
Our clinic doctor may use a combination of physical examination, blood tests, and imaging studies (like Doppler ultrasound, CT angiogram) to diagnose ischemic foot.

Treatment Options:
The primary goal is to improve blood flow. Treatment options include:
- Medications to prevent clots, control blood pressure, and alleviate symptoms
- Lifestyle changes: quitting smoking, managing diabetes, and exercising regularly
- Angioplasty: a procedure to open up narrowed or blocked arteries. This is usually done through a minor surgery, often called a keyhole operation.

Bypass surgery: to reroute blood flow around a blocked artery

In severe cases, amputation may be necessary
Caring for Your Ischemic Foot:
- Regularly inspect your feet for cuts, sores, or color changes.
- Keep your feet clean and moisturized.
- Avoid tight or restrictive footwear.
- Control other health conditions, especially diabetes.
- Quit smoking, if you smoke.
Potential Complications:
If untreated, ischemic foot can lead to:
- Non-healing ulcers
- Gangrene (tissue death)
- Infections
- Amputation

Frequently Asked Questions:
- Is it reversible?
Early detection and treatment can prevent progression and may improve symptoms.
- Can I exercise with ischemic foot?
Yes, but consult with your doctor about the right type and amount of exercise.
Remember, early detection and consistent management are crucial in dealing with ischemic foot. Always consult our clinic doctors with any concerns or questions.
