Vascular closure device

A vascular closure device (VCD) is a medical device used to achieve hemostasis of the small hole in the artery after a cardiac catheterization procedure is performed. These devices are used to close the puncture site in the femoral artery after angiography or angioplasty procedures.

Types of Vascular Closure Devices

Vascular closure devices can be broadly categorized into three types:

• Collagen-based devices: These devices use a plug of collagen to seal the puncture site. The collagen induces clotting and tissue growth to close the hole.

• Suture-based devices: These devices use a suture to stitch the artery closed. They are often used in larger puncture sites or when a more secure closure is needed.

• Sealant-based devices: These devices use a polymer sealant that expands upon contact with blood to seal the puncture site.

Advantages and Disadvantages

Vascular closure devices offer several advantages over traditional manual compression techniques:

• Reduced time to hemostasis: VCDs can significantly reduce the time required to achieve hemostasis compared to manual compression.

• **Increased patient comfort**: Patients often experience less discomfort and can mobilize sooner when a VCD is used.

However, there are also potential disadvantages:

• Risk of complications: There is a risk of complications such as infection, hematoma, or pseudoaneurysm formation.

• Cost: VCDs can be more expensive than manual compression.

Clinical Use

Vascular closure devices are commonly used in interventional cardiology and radiology procedures. They are particularly useful in patients who require early ambulation or have a high risk of bleeding.
