Percutaneous coronary intervention via transulnar sheathless approach

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Access

Background:

• Radial artery access is standard for coronary procedures but can be difficult due to patient anatomy and vessel conditions.
• Challenges include small vessel size, vasospasm, and anatomical variations, limiting catheter and device use.
• The ulnar artery presents a potential alternative access route when radial access is not feasible.

Observation:

• This case report details the successful use of a sheathless technique for percutaneous coronary intervention through the ulnar artery.
• Sheathless catheters have demonstrated safety in prior small studies and a multicenter registry.
• The ulnar artery was utilized when radial artery access was not optimal.

Findings:

• A sheathless percutaneous coronary intervention was successfully performed via the ulnar artery.
• This technique may overcome limitations associated with traditional sheath systems in smaller vessels.
• The sheathless approach potentially reduces risks such as vasospasm, vascular damage, and bleeding.

Implications:

• The sheathless ulnar artery approach could expand treatment options for patients with difficult vascular access during coronary interventions.
• This technique may improve safety and reduce complications, particularly when using larger caliber catheters or treating complex lesions.
• Further research is warranted to validate the safety and efficacy of this approach in a broader patient population.
