EMBLLMPeripheral arterial disease stems primarily from atherosclerosis connected to hypertension, diabetes, elevated lipids, and smoking. Microvascular and endothelial dysfunction further worsen the condition's progression and complications.
For diagnosis and monitoring, duplex ultrasound represents the recommended first-line imaging approach. This non-invasive method provides strong accuracy across most arterial regions while eliminating contrast or radiation concerns — particularly valuable for patients with kidney issues.
Medical Management Strategy
Comprehensive treatment emphasizes risk factor control through smoking cessation, statin use regardless of initial cholesterol levels, blood pressure management, blood thinners (preferably single antiplatelet therapy), and diabetes management. Supervised exercise therapy demonstrates robust evidence for improving symptoms in claudication cases.
Intervention Approaches
Endovascular methods — including balloon angioplasty and stent placement — are generally preferred over surgery for aortoiliac and femoropopliteal disease, offering reduced complications and better quality-of-life outcomes.
Surgical bypass remains optimal for complete femoropopliteal blockages and intricate lesions, though it carries higher procedural risks. An endovascular-first strategy suits most scenarios and higher-risk patients.
Modern advances like 2D fusion imaging and retrograde re-entry catheters have decreased radiation exposure and contrast use while improving technical outcomes for challenging cases.
Treatment Selection
Revascularization strategy should reflect individual lesion characteristics (using TASC II classification), patient health status, and surgical feasibility. Endovascular approaches suit most lesions, though specific infrapopliteal or femoral artery diseases may benefit from open surgery or endarterectomy for improved long-term vessel patency.
