Popliteal artery infarction is a condition where the blood supply to the popliteal artery, located behind the knee, is compromised. This can lead to serious consequences, and understanding the causes, symptoms, diagnostic tests, and treatment options is crucial for effective management.
Types:
Popliteal artery infarction can be classified into two main types:
- Acute Popliteal Artery Infarction:
- Sudden onset.

- Develops gradually over time.
- May exhibit milder symptoms.
Common Causes of Popliteal Artery Infarction:
- Atherosclerosis (hardening of the arteries).
- Blood clots (thrombosis).
- Embolism (blockage from a dislodged clot).
- Trauma to the popliteal region.
- Diabetes.
- Smoking.
