Master Signals Glossary – Helping You Decode the Flow

The formation of new blood vessels from pre-existing ones, crucial for healing and sometimes linked to disease processes.

A non-invasive test comparing blood pressure in the ankle and arm to diagnose peripheral artery disease.

Conditions affecting arteries that reduce blood flow, potentially causing pain, tissue damage, or ulcers.

Hardening or thickening of the artery walls, reducing elasticity and blood flow.

A mass of coagulated blood that can block circulation or travel to vital organs, sometimes leading to life-threatening events.

The movement of blood through the circulatory system, delivering oxygen and nutrients to tissues.

A condition where leg veins struggle to return blood to the heart, leading to swelling, skin changes, and varicose veins.

Alternate pathways of blood flow formed when main vessels are blocked or narrowed.

Elastic garments that help improve blood flow by gently squeezing the legs, used in managing venous disease and swelling.

A blood clot forming in a deep vein, usually in the legs, which can break loose and cause a pulmonary embolism.

Veins located deeper in the body’s tissues, responsible for carrying most of the blood back to the heart. They’re different from superficial veins and require specialized ultrasound techniques for proper imaging.

AI systems that create images or text by gradually transforming random noise into structured output, widely used in generative AI.

Swelling caused by fluid buildup in the tissues, common in venous or lymphatic disorders.

The inner lining of blood vessels that regulates vascular health, blood flow, clotting, and inflammation.

A minimally invasive procedure using heat or chemicals to close problematic veins in conditions like CVI or varicose veins.

A treatment that uses laser energy to close faulty veins, improving blood flow and reducing varicose veins.

The body’s process of breaking down blood clots to restore normal circulation.

Brownish skin discoloration caused by iron deposits, often seen in chronic venous disease.

The study of blood flow, pressures, and resistance within the circulatory system.

The force exerted by fluid in blood vessels, contributing to fluid movement into or out of tissues.

Darkening of the skin often seen around ankles in chronic venous disease due to blood pooling and inflammation.

Pain or cramping in the legs during exercise, caused by poor arterial blood flow.

Swelling caused by lymphatic fluid buildup due to damaged or blocked lymph vessels.

Tiny blood clots that may contribute to chronic symptoms in conditions like Long COVID or vascular inflammation.

Abnormalities in the smallest blood vessels, impairing oxygen delivery and tissue health.

A gas produced by the endothelium that relaxes blood vessels, improving circulation and vascular health.

A drop in blood pressure upon standing, leading to dizziness or fainting.

Narrowing of arteries, usually in the legs, reducing blood flow and causing pain or tissue damage.

The delivery of blood to tissues to supply oxygen and nutrients and remove waste.

Inflammation of a vein, often causing pain, redness, and swelling.

A non-invasive test measuring blood volume changes in the skin, often used for vascular assessments.

Chronic pain and swelling in the legs following a deep vein thrombosis due to damaged veins.

A test measuring blood flow in the limbs to help diagnose arterial disease.

Backward flow of blood in veins due to valve failure, leading to varicose veins and CVI.

Severe pain in the legs even at rest, often indicating advanced peripheral artery disease.

A procedure in which a solution is injected into veins to cause them to collapse and fade from view.

Small, visible veins near the skin surface that often appear red or blue, usually harmless but cosmetic.

Skin inflammation and redness caused by chronic venous insufficiency and poor circulation.

Veins close to the skin’s surface, often visible or prone to becoming varicose. Scanned with higher-frequency ultrasound probes for detailed images.

Vein inflammation associated with blood clot formation, causing pain and swelling.

Formation of a blood clot within a blood vessel, potentially obstructing blood flow.

Open sores on the lower leg caused by poor venous circulation and prolonged pressure buildup.

Failure of vein valves to close properly, allowing blood to flow backward and pool in the legs.

Enlarged, twisted veins caused by weakened vein walls and faulty valves, leading to blood pooling.

Widening of blood vessels to increase blood flow and reduce blood pressure.

A non-invasive imaging test using sound waves to visualize veins and assess blood flow. It’s used to detect blood clots (DVT), valve problems, and vein anatomy. The same ultrasound machine scans both deep and superficial veins, but different probe frequencies and techniques are used for deeper structures.

Increased pressure in veins due to valve dysfunction or obstruction, leading to swelling and skin changes.

Impaired flow of blood back to the heart, often resulting in leg swelling, pain, and skin changes.

Movement of blood from the veins back to the heart, essential for circulation.

Pooling of blood in the veins due to poor circulation, leading to swelling and skin issues.

Medications used to improve vein tone and reduce symptoms of chronic venous disease.
