Comparing Obtura Vascular Closure Device to Manual Compression for Achieving Hemostasis After Percutaneous...

Area of Science:

• Cardiovascular Interventions
• Medical Device Technology
• Clinical Trials

Background:

• Transfemoral catheterization is a common procedure requiring effective vascular access closure.
• Manual compression (MC) is a traditional method, but can be time-consuming and associated with complications.
• Vascular closure devices (VCDs) aim to improve safety and efficiency of hemostasis.

Purpose of the Study:

• To compare the safety and efficacy of the Obtura™ VCD against manual compression (MC) in patients undergoing transfemoral catheterization.
• To evaluate primary endpoints including time to hemostasis (TTH) and deployment success.
• To assess secondary endpoints such as technical success, adverse events, and time to ambulation (TTA).

Main Methods:

• A prospective, randomized, controlled, multicenter trial.
• 268 patients were randomized 1:1 to either the Obtura VCD group or the MC group.
• Safety and efficacy were assessed through TTH, deployment success, technical success, adverse events, and TTA.

Main Results:

• Both technical and deployment success rates were 100% for the Obtura VCD.
• The Obtura VCD group demonstrated significantly shorter TTH (3.26 vs. 23.95 minutes) and TTA (155.44 vs. 723.84 minutes) compared to MC (p<0.0001).
• No access site complications were observed at follow-up; hematoma and pseudoaneurysm rates were low and comparable between groups.

Conclusions:

• The Obtura™ VCD is a safe and effective alternative to manual compression for vascular access closure.
• It significantly reduces time to hemostasis and ambulation, improving patient recovery.
• The device offers advantages in achieving rapid hemostasis with a high success rate and minimal complications.
