Back hand approach to radial access: The snuff box approach

Area of Science:

• Cardiovascular Interventions
• Vascular Access Techniques

Background:

• Transradial access is increasingly standard for coronary procedures.
• Left radial artery access presents advantages for graft cases, including reduced tortuosity.
• Challenges exist regarding patient body mass index and operator ergonomics with left radial access.

Observation:

• Patients with larger body mass or orthopedic limitations (e.g., frozen shoulder) may struggle with standard left radial access positioning.
• The dorsal aspect of the hand offers an alternative access point, allowing natural wrist pronation.
• This approach can accommodate variations in patient anatomy and operator positioning needs.

Findings:

• Dorsal hand radial artery access is a viable alternative to standard radial artery puncture.
• This technique addresses limitations related to patient body habitus and orthopedic constraints.
• It facilitates natural wrist pronation, improving operator and patient comfort.

Implications:

• Expanding radial artery access techniques can enhance procedural success rates.
• This approach may improve patient tolerance and operator experience in transradial interventions.
• Further education on dorsal hand access can broaden interventional cardiologists' skill sets.
