Vascular Bypass Grafting: Restoring Circulation in Peripheral Artery Disease

Skills and Procedures 0
Vascular bypass grafting is a critical surgical intervention designed to redirect blood flow around a section of a blocked or partially blocked artery in the leg. This procedure acts as a biological detour, ensuring that oxygen-rich blood can bypass an obstruction caused by atherosclerosis to reach the lower leg and foot. By restoring proper circulation, this surgery plays a vital role in limb preservation and symptom relief for patients suffering from advanced stages of arterial disease.

The Ankle-Brachial Index Test: Diagnosing Peripheral Artery Disease and Vascular Health

Skills and Procedures 0
The Ankle-Brachial Index (ABI) is a non-invasive diagnostic test used to assess vascular health by comparing blood pressure in the arms and legs. This procedure is the gold standard for detecting peripheral artery disease (PAD), a condition causing reduced blood flow to the limbs due to narrowed arteries. By utilizing a Doppler ultrasound device and standard pressure cuffs, clinicians can calculate a ratio that indicates the severity of arterial blockage, allowing for early intervention and management of cardiovascular risks.

Mechanical Thrombectomy: The Science of Stent Retrievers in Ischemic Stroke Treatment

Skills and Procedures 0
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 Arterial Switch Operation: Correcting Transposition of the Great Arteries

Skills and Procedures 0
The arterial switch operation is a complex, life-saving open-heart surgery performed primarily on newborns to correct a critical congenital heart defect known as Transposition of the Great Arteries (TGA). In this condition, the two main arteries leaving the heart are reversed, preventing oxygenated blood from circulating to the body. This article analyzes the anatomical transformation achieved through this procedure, detailing the physiological correction from a parallel circulation to a normal series circulation.
