Dermatologists see patients with a wide range of lower extremity ulcers, including those caused by venous insufficiency and peripheral arterial disease. Vascular investigations such as the ankle-brachial pressure index, toe pressure, toe brachial index, Doppler arterial waveform, Duplex ultrasonography, and angiography are critical in the prevention, diagnosis, and therapy of vascular illnesses. In fact, dermatologists are frequently the first medical specialists to see patients suffering from severe vascular diseases.
Understanding the right indications, interpretations, limits, and benefits of different vascular tests is crucial to the effective and timely therapy of each patient presenting with a lower extremity ulcer. This study examines the most often requested arterial and venous examinations, as well as the proper reasons and interpretations for these tests.
