Abstract
BackgroundTransradial access (TRA), which has a minimal risk of problems such as radial artery occlusion (RAO), hemorrhage, spasm, and so on, is now considered the standard procedure for cardiac catheterization. The aim of the study is to present the distal transradial access (d-TRA) as a possible promising novel technique in the field of cardiac coronary interventions comparing it to the standard conventional TRA using primary and secondary endpoints, exploring its benefits and drawbacks as a new experience in Alexandria University. One hundred cases with variable indications for coronary interventions were randomized to two arms using systematic random sampling method, coronary interventions in the first one were done via d-TRA (50 patients) and in the second arm via conventional TRA group (50 patients).ResultsTechnically, there were highly statistically significant differences between the two arms in favor of TRA regarding procedural success, number of punctures taken, Access time, Total procedural time, vasodilator used, and crossover to another access site; meanwhile safety profile parameters have showed statistically significant differences in favor of d-TRA regarding post-operative hematoma, AV fistula, post-operative pain and compression time, and there were no statistically significant differences regarding RAO although it occurred more in TRA group.ConclusionsIn the realm of cardiac intervention, the distal radial approach is a promising technique. When compared to TRA, we found it to be a viable and safe method for coronary angiography and interventions and it could be a real option for the interventionists in the near future, with a lower risk of radial artery blockage and no significant differences in wrist hematoma and radial artery spasm. The success rate of d-TRA is proportional to the steepness of the operator's learning curve and the quality of the examples chosen.

Patients One hundred patients were randomized into two arms using systematic random sampling method, coronary interventions in the first arm were done via distal transradial access (d-TRA) (50 patients) and in the second arm via TRA (50 patients)
Results were obtained and tabulated under two groups; group I represents patients in whom d-TRA was used and group II represents patients selected for conventional TRA

Many developments have happened in the treatment of ischemic heart disease over the last few years, one of which is the arterial access route for both coronary angiography and percutaneous coronary procedures [1]. Traditional radial arterial access (TRA) was initially used to perform interventional treatments in 1993. There is considerable skepticism about the use of TRA due to worries about the difficulty to use the radial artery (RA) as a dialysis fistula or as a conduit during coronary artery bypass grafting following TRA (CABG) [6]
