Abstract

To treat coronary artery disease, coronary artery bypass graft (CABG) surgery is done worldwide (CAD). Before harvesting the radial artery for cardiac bypass surgery, Allen's test is frequently used to evaluate the hand's ulnar collateral blood supply. Using Doppler Ultrasonography as a gold standard, this study was created to evaluate the diagnostic precision of Allen's test for the ulnar collateral flow of the donor limb before radial artery
harvesting. This cross-sectional study was conducted from January 2015 to September 2017 at the Jinnah Hospital in Lahore's Cardiac Surgery department. The consecutive sampling/non-probability method was employed. A signed consent form was obtained, and specific demographic data (name, age, and gender) was gathered. SPSS version 21 was used to enter and analyze all of the data. The patients in our study had a mean age of 50.91±9.13 years. The ratio of men to women was 1.3:1. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of Allen’s test was 77.05%, 81.36%, 81.03%, 77.42% & 79.17% taking Doppler test as gold standard. Allen's test, which uses Doppler ultrasonography as the gold standard, is a reliable and valid screening test for the ulnar collateral flow of the donor limb before radial artery harvesting, according to the findings of our study.
