Dual Artery Compression for Patent Hemostasis and Prevention of Radial Artery Occlusion: The Quebec Terry2 Registry.

BACKGROUND

Radial artery occlusion (RAO) is a common complication following transradial artery access (TRA). Patent hemostasis is recommended to reduce RAO. Prophylactic ulnar artery compression is a technique to increase the rate of patent hemostasis.

AIMS: To evaluate the efficacy and safety of prophylactic ulnar artery compression in achieving patent hemostasis and preventing RAO after TRA with the Terry2, a novel dual artery hemostasis device.

METHODS

Patients undergoing coronary catheterization in three Quebec hospitals were included. A specific patent hemostasis protocol was used with the device. Radial artery patency using digital oximetry was assessed after Terry2 placement and prior to hospital discharge. Nursing workload and patient comfort were also assessed.

RESULTS

A total of 578 patients were included and followed up for 30 days. The average age was 69 ± 11 years, and 70% were male. Right radial access was used in 91% of cases. The introducer size was 5 Fr in 80% of cases. Patent hemostasis was 100%. The average time to hemostasis was 121 ± 41 min. At 30 days, RAO was found in a single patient (0.2%). Patients reported a high level of comfort, with 92% feeling "comfortable or very comfortable." A 10-15 min per patient reduction in nursing time was reported compared to standard single artery compression.

CONCLUSIONS

Dual artery compression with the Terry2 is an effective and safe strategy for achieving patent hemostasis and preventing RAO after coronary catheterization via TRA. This approach is associated with high success rates, patient comfort, and a potential substantial reduction in nursing workload.
