The role of the ankle brachial pressure index in the diagnosis of peripheral arterial injury.

Background: Angiography is the "gold standard" diagnostic tool for patients presenting soft signs of arterial injury. To reduce the number of unnecessary angiographies, we aimed to evaluate the role of the ankle brachial pressure index (ABPI) in the diagnosis of peripheral arterial injury in extremity trauma with soft signs.

Methods: The data of 1772 patients with the suspicion of peripheral arterial injury was recorded prospectively.
