Background: Chronic total occlusion (CTO) revascularisation has a crucial role in contemporary percutaneous coronary intervention (PCI). Procedural success is influenced by disease complexity, calcific burden and patient characteristics but has substantially improved with the implementation of novel hybrid strategies. However, vascular-access related complications remain a cause of morbidity and mortality. This study aimed to assess the effectiveness of fluoroscopic-guided femoral arterial puncture to minimise this risk during CTO PCI.
Methods: Standardised data were retrospectively collected from four high-volume UK CTO centres between September 2011 and November 2013. Demographic, clinical and procedural data (vascular access site, sheath size, anticoagulation use) was collated. The anatomical location of the femoral puncture in relation to the femoral bifurcation, femoral head position and inferior epigastric artery were recorded. Adverse events related to vascular access were documented.
Results: A total of 528 patients were included (676 femoral punctures) with the majority being male (n=432, 81.8%). Large sheaths (8F) were used in 81.2% of cases. Fluoroscopy-enabled punctures were made in the 'safe zone' in over > 93% of cases. Vascular closure devices (VCD) were used in 88.3% of cases. The adverse event rate per puncture was 0.89%.
Conclusions: This study demonstrates an extremely low incidence of vascular-access complications in CTO PCI when fluoroscopic guidance is used to obtain femoral arterial access by default radial operators.
