“PVD” can mean different conditions. In medicine, the common meanings are:
  1. Peripheral vascular disease: arterial or venous disease affecting limbs, often used to mean peripheral artery disease (PAD).
  2. Posterior vitreous detachment: separation of the vitreous gel from the retina in the eye.

Assuming PVD = peripheral vascular disease, usually referring to peripheral artery disease (PAD) of the lower limbs. It is most often caused by atherosclerotic narrowing or blockage of leg arteries. It causes reduced blood flow, may produce exertional calf pain, non-healing foot ulcers, gangrene, and also signals a higher risk of myocardial infarction and stroke.

  1. Definition and types: arterial, venous, acute and chronic disease
  2. Causes and risk factors
  3. Pathophysiology
  4. Clinical features: claudication, critical limb ischemia, acute limb ischemia
  5. Examination and pulse findings
  6. Investigations: ABI, Doppler, duplex ultrasound, CT/MR angiography
  7. Differential diagnosis of leg pain and ulcers
  8. Management: risk-factor treatment, exercise, antiplatelets, statins, cilostazol, revascularization
  9. Complications and prognosis
  10. Nursing/foot-care points and exam-oriented tables
Current guidelines classify lower-extremity PAD as asymptomatic PAD, chronic symptomatic PAD including claudication, chronic limb-threatening ischemia, and acute limb ischemia. Treatment combines smoking cessation, diabetes and blood-pressure control, high-intensity statin therapy, antithrombotic therapy when appropriate, structured exercise, foot care, and revascularization when symptoms remain disabling or limb viability is threatened, as summarized by the 2024 ACC/AHA PAD guidance.
Tell me which section you want in full detail, or say “complete exam note” and specify your level: MBBS, nursing, or postgraduate. If by PVD you meant posterior vitreous detachment of the eye, say so.

Give me a complete exam note on peripheral vascular disease

Reading File
A complete exam note on peripheral vascular disease (PVD) can cover both arterial disease and venous disease, although in many exams PVD is used mainly for peripheral arterial disease (PAD).

High-level overview

PAD results from reduced arterial flow to the limb, most commonly due to atherosclerosis. Its classic symptom is intermittent claudication, an exertional, reproducible cramping pain in a muscle group supplied distal to an arterial narrowing that resolves with rest. Advanced ischemia produces rest pain, non-healing ulcers, and gangrene. An ABI below 0.90 supports the diagnosis; values below 0.40 generally indicate severe disease, while values above 1.30 can reflect non-compressible calcified vessels.
PAD must be treated as both a limb disease and a systemic cardiovascular disease. Core care includes smoking cessation, structured walking exercise, antiplatelet therapy when indicated, high-intensity statin therapy, and management of diabetes, blood pressure, and other cardiovascular risks. Revascularization is used for lifestyle-limiting symptoms despite optimal non-operative therapy, and urgently for threatened limb viability. The current ACC/AHA PAD guideline summary emphasizes foot care, structured exercise, risk-factor management, and multidisciplinary care.
