Abstract
While the transradial approach is now a well-established alternative to the conventional femoral approach for cardiac catheterization, the ulnar artery is rarely used. The objective of this prospective study was to evaluate the feasibility and safety of transulnar catheterization for routine diagnostic and therapeutic coronary interventions. Among 210 consecutive patients referred for diagnostic coronary angiography and or angioplasty and screened for appropriateness of the ulnar approach, 172 (172 of 210, 82%) underwent attempted ulnar artery catheterization, which was successful in 158 (158 of 172, 91%). The 173 procedures successfully performed via the ulnar approach included 122 diagnostic coronary angiographies, 38 coronary angiographies followed by angioplasty, and 13 elective angioplasties. Access site complications consisted of one case each of silent ulnar artery thrombosis, pseudoaneurysm, and hematoma due to ulnar artery wall rupture during an unsuccessful catheterization attempt. No cardiac or systemic complications were recorded. The transulnar approach appears feasible and safe for routine coronary diagnostic and therapeutic interventions.
