🔍 Quick Summary
Peripheral vascular disease (PVD) affects blood flow outside the heart and brain.
It commonly causes reduced circulation to the legs.
1️⃣ Introduction
Peripheral vascular disease refers to problems with blood vessels outside the heart.
• commonly affects arteries in the legs
• reduces blood flow to muscles and tissues
• often develops gradually
👉 It is often linked to atherosclerosis (narrowing of arteries).
2️⃣ How it happens
Blood vessels become narrowed or blocked.
• fatty deposits build up in vessel walls
• blood flow reduces
• tissues receive less oxygen
👉 This leads to pain and poor healing.
3️⃣ Types
• Peripheral artery disease (PAD)
→ narrowing of the arteries
→ reduces blood flow to the legs or organs
→ most common and usually more serious type
• Venous disease
→ affects the veins
→ can cause swelling, pooling of blood, or varicose veins
• Lymphatic disease
→ affects lymph drainage
→ may cause fluid build-up and swelling (lymphedema)
👉 Arterial disease often carries the highest risk because reduced blood flow can damage tissues
4️⃣ Common causes
• smoking
• diabetes
• high blood pressure
• high cholesterol
5️⃣ Symptoms of arterial disease (PAD)
• leg pain when walking (claudication)
• pain improves with rest
• cold or numb limbs
👉 These symptoms happen because blood no flow well to the legs
6️⃣ Symptoms of venous disease
• leg swelling
• heavy or aching legs
• varicose veins
• skin darkening around the ankles
👉 These signs happen when blood dey pool for the veins
7️⃣ Lymphatic symptoms
• persistent swelling
• tight or heavy feeling in the limb
👉 This fit happen when fluid drainage no work properly
8️⃣🩺 When it becomes dangerous 🚨
• severe pain at rest
• non-healing ulcers
• black or discolored toes
👉 These may indicate:
• critical limb ischemia
• risk of tissue damage or amputation
9️⃣Management / treatment
• stop smoking
• exercise (walking programs)
• medications (e.g. antiplatelets)
🟦 Diagnosis
• physical examination
• ankle-brachial index (ABI)
• imaging (ultrasound, angiography)
👉 Tests assess blood flow in the limbs.
🟢 Important message
Peripheral vascular disease is manageable and often preventable.
👉 Early lifestyle changes can improve circulation and reduce complications.
FAQ
• Is PVD the same as PAD?
PAD is a type of PVD affecting arteries.
• Can walking help?
Yes—regular walking improves circulation.
