Percutaneous trans-ulnar versus trans-radial arterial approach for coronary angiography and angioplasty, a preliminary experience at an Egyptian cardiology center

摘要

Background:Trans-ulnar approach was proposed primarily for elective procedures in patients not suitable for trans-radial approach that was introduced two decades ago. The trans-ulnar approach is as safe and effective as the trans-radial approach for coronary angiography and intervention.AimThis study’s aim was to assess the feasibility and safety of the trans-ulnar approach in coronary procedures as a preliminary experience for operators experienced in trans-radial approach with no/minimal trans-ulnar approach experience at an Egyptian center.ResultsVascular access in 120 patients was selected randomly for coronary angiography and angioplasty—80 through radial and 40 through ulnar approach. Patients were examined for local complications and Doppler evaluation to both radial and ulnar arteries a day after the procedure was done. Ulnar approach success was 82.5% versus 93.7% in the radial group; failure of ulnar artery puncture was the only cause of crossover in the ulnar group, while occurrence of persistent spasm was the leading cause of crossover in the radial group followed by radial artery tortuosity. The procedure time of coronary angiography and percutaneous coronary intervention of the ulnar group was significantly higher than that of the radial group (P value?=?0.011 and 0.034, respectively). The mean caliber of the right ulnar artery was 2.45?±?0.38, slightly larger than that of the radial artery 2.33?±?0.38 at the level of the wrist, but this difference was statistically non-significant.ConclusionOur study demonstrated that ulnar access with experienced radial operators and in our patients is a safe and practical approach for coronary angiography or angioplasty, without any major complications. Bearing in mind its high success rate, it can be used when a radial artery is not useful for the catheterization or as a default approach on the expense of slightly longer procedural time.
