Peripheral arterial disease: diagnosis, treatment, and systemic implications

Area of Science:

• Vascular Medicine
• Cardiology
• Angiology

Background:

• Peripheral arterial disease (PAD) is a prevalent condition in adults, frequently coexisting with lower extremity ulcers.
• PAD diagnosis is critical due to its impact on limb health and its association with systemic atherosclerotic disease.
• Many patients with PAD are asymptomatic or present with atypical symptoms, complicating diagnosis.

Purpose of the Study:

• To highlight the importance of diagnosing peripheral arterial disease in adults, particularly those with lower extremity ulcers.
• To review diagnostic methods and therapeutic strategies for managing PAD.
• To emphasize the systemic implications of PAD beyond the lower extremities.

Main Methods:

• Physical examination for clinical assessment.
• Ankle-brachial index (ABI) measurement for noninvasive diagnosis.
• Referral to noninvasive vascular laboratories for further testing.
• Advanced imaging techniques such as contrast angiography and magnetic resonance angiography (MRA).

Main Results:

• Diagnostic tools like ABI, vascular lab studies, and angiography aid in identifying PAD.
• Effective therapies include smoking cessation, exercise, lipid management, antiplatelet agents, and control of hypertension and diabetes.
• Cilostazol may benefit patients with symptomatic claudication.
• Interventional referral is recommended for nonhealing ulcers, rest pain, or severe claudication.

Conclusions:

• Prompt diagnosis of PAD is essential due to its association with critical limb ischemia and systemic atherosclerosis.
• A multi-faceted approach combining diagnostic evaluations and comprehensive therapeutic interventions improves patient outcomes.
• Management strategies should address risk factors and consider interventions for advanced disease.
