The distal radial artery: Versatile vascular access for transcatheter interventions

Area of Science:

• Cardiovascular Interventions
• Vascular Access Techniques

Background:

• Conventional transradial access is the guideline-recommended standard for coronary angiography and interventions.
• Distal radial artery access (snuffbox approach) is an emerging alternative transradial site.
• This technique allows sheath insertion with the hand in a pronated position.

Purpose of the Study:

• To review current literature on distal radial artery access scenarios.
• To evaluate the feasibility of distal radial access for diverse transcatheter interventions.
• To address the ongoing debate regarding its benefits and limitations.

Main Methods:

• Literature review of studies utilizing distal radial access.
• Analysis of case series and comparative studies.
• Assessment of reported outcomes and complication rates.

Main Results:

• Distal radial access is increasingly adopted, with reported advantages in reduced vascular complications and improved hemostasis.
• Evidence regarding its benefits and applicability across all interventions remains dynamic and sometimes discrepant.
• Concerns persist about its suitability for all procedures due to anatomical differences.

Conclusions:

• Distal radial access shows promise as a valuable alternative transradial approach.
• Further robust evidence is required to definitively establish its role and safety for all interventional scenarios.
• The technique's widespread adoption may depend on ongoing research and operator experience.
