Venous leg ulcers can be caused by chronic venous insufficiency (CVI)1. This can be caused by reflux in any of the venous systems – whether superficial, perforator, or deep – when the valves of the veins have failed or the vein has become obstructed2. 2014 SVS/AVF venous leg ulcer guidelines recommend comprehensive venous duplex ultrasound examination of the lower extremity in all patients with a suspected venous leg ulcer, in order to identify the cause3.
STEP 1: DIFFERENTIATE ARTERIAL ULCER FROM VENOUS ULCER
Ulcer appearance together with the medical history and physical exam should be used to determine the different diagnosis and see if a venous leg ulcer is suspected.
STEP 2: TEST FOR CHRONIC VENOUS INSUFFICIENCY (CVI)
Comprehensive Venous Duplex Ultrasound Examination of the lower extremity should be performed in all patients with a suspected venous leg ulcer in order to identify the cause. The Society of Vascular Surgery (SVS) and the American Venous Forum (AVF) 2014 venous leg ulcer guidelines provide a strong recommendation for conducting this exam.
STEP 3: IDENTIFY THE UNDERLYING CAUSE
Venous leg ulcers can be caused by chronic venous insufficiency (CVI)1, a more serious form of venous reflux disease which can cause reflux in any of the venous systems – superficial, perforatoror deep. Ultrasound testing will help define the underlying cause of this disease and help in determining the right treatment for patients.
