Vascular access and chronic total occlusion angioplasty

Abstract

The hybrid algorithim approach, together with innovative new technologies, has lead to increased interest in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and increasing procedural success rates. Unlike non-CTO PCI, there is an increased rate of femoral access. When considering arterial access in CTO PCI, a balance is needed between anticipated procedural difficulty, planned CTO strategy and the desire to minimise the risk of vascular access-related complications. We review the evidence for best practice with respect to femoral puncture technique and also assess the technologies and techniques available to place larger inner diameter catheters into the radial artery.
