Early diagnosis and treatment is important in peripheral arterial disease. Peripheral arterial disease is difficult to diagnose accurately with history and physical examination. A variety of diagnostic methods for peripheral arterial disease are available. The Ankle-brachial index (ABI) and the Toe-brachial index (TBI) are simple and useful methods for that can be performed in the office setting. The aim of this study was to compare the ability to detect peripheral arterial disease between the ABI and the TBI in patients did lower extremity angiography. Forty two patients were included in this study. Total 82 extremities were studied among these patients. Ankle-brachial index and Toe-brachial index were measured. All patients were investigated by lower extremity angiography. The sensitivity and specificity for Ankle-brachial index were 68.2% and 86.8%. The sensitivity and specificity for Toe-brachial index were 82.6% and 79.2%. Six limbs diagnosed to peripheral arterial disease by lower extremity angiography, were detected normal Ankle-brachial index and low Toe-brachial index. Three limbs diagnosed to peripheral arterial disease by lower extremity angiography, were detected normal Ankle-brachial index and Toe-brachial index. The result indicate that Toe-brachial index is more sensitive method to detect peripheral arterial disease. But Toe-brachial index alone are less efficient, because of its low specificity. It is beneficial to combine Ankle-brachial index and Toe-brachial index for detecting peripheral arterial disease.
