Abstract Background There are many feasible ways to reach the coronary arteries through a percutaneous technique. Till now, the most commonly used approach is the radial artery approach because it has the lowest risk of known vascular adverse events. However, it could not be an option in some situations as congenital radial artery hypoplasia and radial artery spasm. In these cases, the second most common access is the femoral artery access. The current literature over the brachial artery access is controversial. Our study's objective is to verify the brachial artery approach's effectiveness and safety. Methods We studied 300 patients who underwent elective coronary angiography and percutaneous angioplasty in our institution with failed radial access between August 2022 and February 2023. They were classified into two groups; 150 patients in a group with brachial access and 150 in a group with femoral access. Baseline clinical and demographic traits of all enrolled patients were obtained from hospital records and the cardiovascular risk factors were identified. Venous blood samples, resting 12-lead electrocardiogram and transthoracic echocardiography were done before the coronary angiography. Access, procedural and fluoroscopy times were recorded. Doppler evaluations of both brachial and femoral arteries were done the day after the procedure. All patients were examined carefully immediately after the procedure and before discharge to assess any complications. Results Our data showed that no statistically significant difference between the studied groups regarding the cardiovascular risk factors, demographic, clinical and laboratory characteristics. Left brachial access was used more frequently than left femoral access (32.7% vs. 22.7%, p= 0.05), but no significant difference regarding right sided or bilateral access. Procedure time, fluoroscopy time, and contrast volume did not differ significantly (p=0.19, 0.06 and 0.1 respectively). However, brachial group had shorter access time (2.6 ±1.1 vs. 3.4 ± 0.7 minutes, p=0.05) and shorter hospital stay (3.5 ± 1.1 vs. 5.9 ± 1.3 days, p0.001). Regarding complications, both major and minor complications were significantly lower in the brachial arm (p=0.04 and 0.05, respectively). Conclusion Brachial artery access is a safe, efficient alternative and non-inferior to the femoral route for coronary intervention whenever radial access is not an option.
