Critical Limb Ischemia (CLI)

Critical Limb Ischemia or CLI is a severe obstruction of the arteries which seriously decreases blood flow to the extremities (hands, feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores.

Congenital Vascular Malformation (CVM)

“Vascular anomalies” is an all-inclusive term for vascular malformations, vascular tumors, and other congenital vascular defects. The more commonly used term, Congenital Vascular Malformation (CVM), implies abnormally formed blood vessels that one is born with.

Deep Vein Thrombosis (Venous Disease)

Deep Vein Thrombosis, commonly referred to as “DVT”, occurs when a blood clot, or thrombus, develops in the large veins of the legs or pelvic area.

Peripheral Arterial Disease (PAD)

PAD is also known as atherosclerosis, poor circulation, or hardening of the arteries.

Raynaud’s Disease (Raynaud’s Phenomenon)

Raynaud’s phenomenon is a medical condition in which the arteries in the fingers and toes become suddenly narrowed in response to cold exposure, causing the digits to turn sequentially white, blue, or red.

Renovascular Hypertension (RAS)

Renovascular hypertension is high blood pressure related to narrowing, or partial blockage of the blood vessel that carries blood to the kidney.


A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts.
