| Popis: | INTRODUCTION: Peripheral arterial disease (PAD) is a condition characterized by atherosclerotic occlusive disease of the lower extremities. While PAD is a major risk factor for lower- extremity amputation, it is also accompanied by a high likelihood for symptomatic cardiovascular and cerebrovascular disease. Atherosclerosis accounts for more than 90% of cases of PAD, and uncommon vascular syndromes account for the remaining 10%. The femoral and popliteal arteries are affected in 80% to 90% of symptomatic PAD patients, the tibial and peroneal arteries in 40% to 50%, and the aortoiliac arteries in 30%.Although 65-75% of patients with PAD are asymptomatic, the classic presenting symptom is usually described as muscle cramps, fatigue or pain in the lower legs induced by exercise and rapidly relieved by rest; often the symptom location indicates the level of arterial involvement. RISK FACTORS: Diabetes and smoking are the strongest risk factors for PAD. Other well-known risk factors are advanced age, hypertension, and hyperlipidemia. DIAGNOSIS: PAD can be easily and accurately diagnosed by calculating the ankle-brachial index (ABI).The ABI is defined as the ratio of the systolic blood pressure in the ankle divided by the systolic blood pressure at the arm. The tools required to perform the ABI measurement include a hand-held 5-10 MHz Doppler probe and a blood pressure cuff. MANAGEMENT: Most patients' symptoms improve with optimal medical treatment and invasive intervention is often not required. Smoking cessation and exercise are considered the two most important treatments for PAD. CONCLUSION: Symptomatic PAD often impairs a patient's quality of life and untreated disease can lead to limb loss. Aggressive management of atherosclerotic risk factors, a structured exercise program, use of antiplatelet agents and when indicated percutaneous or surgical revascularizations are the keys for successful |
