Background:
Distal transradial access (dTRA) has received extensive attention and has gradually become an alternative access for cardiac interventions. However, with the widespread use of dTRA, access complications such as distal radial artery occlusion (dRAO), haematoma, pseudoaneurysm and arteriovenous fistula (AVF) have been reported. In this study, we report a case of AVF after dTRA and review the related literature.
Case Report:
A 54-year-old female, who underwent percutaneous coronary intervention (PCI) 2 years ago, was admitted to the hospital with discomfort in her thumb. On admission, a mass was found at the puncture site, and ultrasound revealed a fistula between the distal radial artery (DRA) and the cephalic vein (CV). The patient was treated with manual compression for 2 h. Three months later, the mass was smaller than before, the symptoms had resolved and the fistula was found to have closed on repeat ultrasound.
Conclusion:
Understanding the mechanisms underlying the occurrence of AVF and the principles guiding the treatment of the potential risks associated with AVF after dTRA is important and allows for the effective prevention of AVF and accurate prognostic prediction.
