Claudication[edit | edit source]
Introduction[edit | edit source]
Claudication refers to a condition characterized by cramping pain in one or both legs during walking, often leading to limping. This symptom is typically a manifestation of Peripheral Arterial Disease (PAD) which results from reduced blood flow in the leg arteries.
Causes and Pathophysiology[edit | edit source]
Atherosclerosis[edit | edit source]
The primary cause of claudication is atherosclerosis, a process where plaque builds up in the arteries, narrowing them and reducing blood flow.
Other Causes[edit | edit source]
Other factors contributing to claudication include:
- Diabetes
- High blood pressure
- High cholesterol levels
- Tobacco use
Symptoms[edit | edit source]
Patients with claudication typically experience:
- Pain or cramping in the legs while walking
- Numbness or weakness in the legs
- Reduced walking distance due to pain
- Symptoms improve with rest
Diagnosis[edit | edit source]
Diagnosis of claudication involves:
- Physical examination
- Ankle-Brachial Index (ABI) test
- Doppler ultrasound
- CT or MR angiography
Treatment[edit | edit source]
Treatment options for claudication include:
- Lifestyle changes (e.g., quitting smoking, exercise)
- Medications to improve blood flow
- Surgical interventions like angioplasty or bypass surgery
Prognosis[edit | edit source]
With appropriate treatment, most individuals can manage symptoms effectively. However, it's crucial to address the underlying cause to prevent progression of the disease.
