Distal Radial Pseudoaneurysm After Chronic Total Occlusion Percutaneous Coronary Intervention Resolved by Percutaneous Thrombin Injection

Background: The distal radial approach was recently introduced with the hope to improve patients' comfort, particularly during left wrist access and maybe to reduce the rate of complications (mainly radial artery occlusion). However up to now, little is known about the real incidence and type of complications related to this access site.

Case presentation: We report the case of a left distal radial pseudoaneurysm complicating a successful percutaneous recanalization of a right coronary artery chronic total occlusion with bilateral wrist approach (right radial artery retrograde and left distal radial artery antegrade). This complication was successfully resolved by percutaneous thrombin injection.

Conclusion: Our case proves that dTRA is not free from conventional vascular complications and this should be considered during the planning of the best strategy for our patients.
