Subclavian Artery Occlusion

Subclavian artery occlusion occurs when there is a blockage in one of the major arteries supplying blood to the arms. In simple terms, it restricts the blood flow to the arms, leading to various health issues. Let’s break down the essential aspects of subclavian artery occlusion in plain English.

Types:

1. Atherosclerosis-Related Occlusion: This type occurs when fatty deposits build up inside the artery walls, restricting blood flow.
2. Embolic Occlusion: Caused by blood clots or debris traveling through the bloodstream and blocking the subclavian artery.
3. Thrombotic Occlusion: A blood clot forms directly within the subclavian artery, obstructing normal blood flow.
4. Traumatic Occlusion: Occurs due to injury, like a dislocation or fracture, leading to compression or damage to the subclavian artery.

Causes

1. Atherosclerosis: The main cause, where plaque accumulates in the artery walls.
2. Blood Clots: Formation of clots in the bloodstream that can travel and block the subclavian artery.
3. Inflammation: Conditions like vasculitis can lead to inflammation, contributing to occlusion.
4. Smoking: Tobacco use is a significant risk factor for developing arterial issues.
5. High Blood Pressure: Prolonged hypertension can damage artery walls, increasing the risk of occlusion.
6. Diabetes: Poorly managed diabetes can accelerate atherosclerosis.
7. Genetic Factors: Some individuals may have a genetic predisposition to arterial problems.
8. Age: The risk increases with age due to the gradual wear and tear of arteries.
9. Obesity: Excess weight can contribute to atherosclerosis and hypertension.
10. Lack of Physical Activity: Sedentary lifestyles are linked to arterial health issues.
