Degenerative stenosis of the posterior tibial artery is a condition where the blood vessels supplying the lower leg and foot narrow over time, leading to reduced blood flow. In simpler terms, it’s a health issue that affects the circulation in the lower extremities. Let’s break down this condition into comprehensible details to promote easy understanding.
The gradual narrowing of the posterior tibial artery, a major blood vessel in the lower leg responsible for supplying blood to the calf, ankle, and foot. This narrowing impedes blood flow, affecting the tissues in the lower limb.
Types:
There are two primary types of degenerative stenosis of the posterior tibial artery:
- Atherosclerosis-induced stenosis: Caused by the buildup of plaque in the artery walls, restricting blood flow.
- Degenerative changes in the artery: Gradual wear and tear on the artery, leading to narrowing and reduced blood circulation.
Causes
- Aging: Natural wear and tear on the arteries.
- Smoking: Increases the risk of plaque buildup.
- Diabetes: Can contribute to arterial damage.
- High blood pressure: Puts strain on artery walls.
- High cholesterol: Leads to plaque formation.
- Obesity: Increases the risk of arterial diseases.
- Sedentary lifestyle: Lack of physical activity affects blood circulation.
- Genetics: Family history of vascular issues.
- Inflammatory conditions: Such as vasculitis.
- Peripheral artery disease (PAD): Affects blood vessels outside the heart and brain.
- Chronic kidney disease: Impacts overall vascular health.
- Hypothyroidism: Underactive thyroid function can contribute.
- Trauma: Physical injury to the lower limb.

- Blood clotting tests: Assess the risk of clot formation.
- Capillaroscopy: Examines small blood vessels in the nailfold to detect abnormalities.
- C-reactive protein (CRP) test: Measures inflammation in the body.
- Echocardiogram: Assesses the heart’s pumping function and potential sources of emboli.
