Popliteal Artery Dissection

Popliteal artery dissection is a condition involving the tearing or separation of the popliteal artery, a crucial blood vessel located behind the knee. This article aims to provide a clear and accessible overview of popliteal artery dissection, covering types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical interventions.

Types of Popliteal Artery Dissection:

Popliteal artery dissections can be broadly categorized into two types:

1. Traumatic Dissection:
