Mechanical thrombectomy is a revolutionary endovascular procedure used to physically remove blood clots from large blood vessels, most commonly to treat acute ischemic stroke. This minimally invasive technique involves threading specialized devices through the vascular system to entrap and extract the obstruction, restoring critical blood flow to the brain. The illustration provided demonstrates the step-by-step mechanism of a stent retriever, a specific tool designed to integrate with the thrombus for safe removal.

The human vascular system relies on a network of flexible, unobstructed tubes to transport oxygen-rich blood to vital organs, but this system can be compromised by the gradual progression of arterial disease. This article analyzes a comparative diagram of a normal artery versus a diseased artery, highlighting the structural changes caused by cholesterol accumulation and the acute danger of thrombus formation. Understanding these anatomical differences is essential for recognizing the risks associated with cardiovascular conditions such as atherosclerosis and coronary artery disease.

This diagram clearly illustrates carotid endarterectomy, a surgical procedure designed to remove plaque buildup from the carotid arteries. These vital arteries in the neck supply blood to the brain, and blockages can significantly increase the risk of stroke. The images depict the stages of plaque removal and the subsequent repair of the artery, highlighting a crucial intervention in neurovascular health.

This medical illustration depicts three primary types of stroke: atherosclerotic, hemorrhagic, and ischemic cerebrovascular accidents (CVAs). Each diagram demonstrates distinct pathophysiological mechanisms leading to brain tissue damage through different vascular complications.
