Percutaneous Vascular Closure System Based on an Extravascular, Bioabsorbable Polyglycolic Plug (ExoSeal): Results...

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Devices

Background:

• Percutaneous transfemoral interventions are common but require effective hemostasis.
• Achieving rapid and safe closure of the arteriotomy site is crucial for patient recovery.
• Existing closure methods have varying success rates and complication profiles.

Purpose of the Study:

• To evaluate the effectiveness and safety of the ExoSeal percutaneous closure system.
• To assess the hemostasis success rate using a polyglycolic acid plug.
• To determine complication rates associated with the device.

Main Methods:

• Prospective study of 1000 patients undergoing 6F sheath interventions.
• Utilized the ExoSeal percutaneous vascular closure system.
• Follow-up included clinical assessment and color-coded duplex ultrasound at 24 hours and 6 weeks.

Main Results:

• Immediate hemostasis was achieved in 93.9% of patients (939/1000).
• Device positioning failure occurred in 6.1% due to anatomical or device issues, managed with manual compression.
• Minor complications occurred in 7.4%, including hematomas and pseudoaneurysms; one retroperitoneal bleed required transfusion.

Conclusions:

• The percutaneous ExoSeal closure system provides safe and effective hemostasis for 6F transfemoral punctures.
• The device is a viable option for achieving rapid arteriotomy closure.
• Further monitoring confirmed the system's safety profile.
