Arterial Conditions

• Peripheral Artery Disease (PAD) 

  When the arteries in your legs become narrowed or blocked, reducing blood flow. This can cause leg pain when walking, cramping, cold feet, slow-healing wounds, or changes in skin color. 

• Critical Limb Ischemia (CLI) 

  A severe form of poor circulation where blood flow to the leg or foot is very limited. Symptoms can include constant pain, color changes, sores that won’t heal, or tissue damage. This condition needs urgent care. 

• Claudication

  Pain, cramping, or tightness in the legs that happens when walking and improves with rest. It’s often a sign of reduced blood flow in the arteries. 

• Chronic Limb-Threatening Ischemia (CLTI)

  Long-term, severe circulation problems that can cause ongoing pain, wounds, or infections in the foot or leg. Without treatment, it can put the limb at risk.

• Carotid Artery Disease 

  Narrowing of the arteries in the neck that supply blood to the brain. This can increase the risk of stroke and may cause symptoms like dizziness or vision changes—or no symptoms at all. 

• Renal Artery Stenosis

  Narrowing of the arteries that supply blood to the kidneys. This can affect blood pressure control and kidney function. 

• Acute Limb Ischemia 

  A sudden loss of blood flow to a leg or arm. Symptoms may include sudden pain, coldness, numbness, or color changes. This is a medical emergency.
