Real-time ultrasound-guided hemostasis using suture-mediated closure device

Area of Science:

• Vascular Surgery
• Medical Devices
• Diagnostic Imaging

Background:

• Suture-mediated hemostasis devices require significant training and rely on tactile feedback for optimal compression.
• Limitations in identifying the precise compression point can lead to technical failures and prolonged procedures.

Purpose of the Study:

• To evaluate the efficacy of ultrasound guidance in improving outcomes with suture-mediated hemostasis devices.
• To determine if ultrasound guidance reduces technical failure and the need for additional manual compression.

Main Methods:

• A retrospective study of 104 patients undergoing common femoral artery access closure using ProGlide vascular closure device.
• Comparison of ultrasound-guided hemostasis (54 patients) versus conventional hemostasis (50 patients).
• Analysis of procedural data, including time to hemostasis, technical success rates, and complications.

Main Results:

• Technical success rates were comparable: 52/54 (ultrasound-guided) vs. 47/50 (conventional).
• Mean hemostasis time was shorter with ultrasound guidance (271s vs. 317s).
• Significantly less additional manual compression was required in the ultrasound-guided group (7/54 vs. 15/50, p<0.05).

Conclusions:

• Ultrasound guidance enhances the use of suture-mediated closing devices by reducing the need for additional manual compression.
• This technique does not elevate the risk of complications such as hematoma, pseudoaneurysm, or access site infection.
