Vascular closure device
Vascular closure device are medical devices used to achieve hemostasis of the small hole in the artery.
Some facts about Vascular closure device:
- Vascular closure device is used after a cardiovascular procedure of endovascular surgery requiring a catheterization.
- Diagnostic procedures are involved in cardiovascular procedures requiring catheterization that help diagnose diseased blood vessels and interventional procedures such as angioplasty, the placement of a stent and coronary thrombectomy.
- The main goal of a Vascular Closure Device is to reduce access site complications and to provide rapid hemostasis of the artery.
- Time to ambulation and time to hospital discharge can also be reduced by VCD.
- The main method for closing the femoral artery was manual compression prior to the development of VCD.
- However, VCD are more comfortable for the patient compared to manual compression.
- Vascular Closure Devices were introduced in the early 1990s in an effort to improve patient comfort, reduce the time to hemostasis, and enable early ambulation.
- A suture or a collagen plug is involved in the devices focused on technologies which are effective at closing the hole.
- However, an intravascular component are often left in the artery, which can cause complications.
- These technologies also failed to accurately address patient pain.
- Novel materials that dissolve over a short period of time, such as polyethylene glycol found in the Mynx vascular closure device are used in more recent methods to close the hole.
- A more gentle deployment of the material to the outside of the artery is incorporated in these technologies.
- The use of intravascular components can also be avoided, leaving nothing behind in the artery and consequently improving patient comfort.
- VCD shouldn't be used for patients with double wall punctures since the device will not close a puncture of the posterior wall.
- The risk of bleeding against the benefits of the VCD can be weighed before insertion for patients who have received glycoprotein IIb/IIIa receptor inhibitors
- VCD can be subclassified into four groups: collagen based systems, surface pads with haemostatic substances, suture-mediated or rather clip closure systems, and multiple-component systems.
Preparation for a CT Guided Biopsy:
- Your doctor should be notified if you are sensitive or are allergic to any medications, latex, iodine, tape, or anesthetic agents (local and general).
- Drinking and eating anything the night before the implantation is restricted.
- Your doctor should be notified of all medications including prescription and over the counter and herbal or other supplements that you are taking.
- A blood test prior to the biopsy may be done to determine how long it takes your blood to clot.
- A sedative will be given before the procedure to help you relax.
- Blood pressure medication should be taken as scheduled with a sip of water.
- Other specific preparation may be requested by your doctor based on your medical condition.
Procedure for implanting Vascular closure device:
- A small incision is made in the groin area and a hole is created in the femoral artery to gain access to the artery during the procedure.
- This hole is referred to as the access site or puncture site which needs to be closed after the completion of the procedure.
- Time to hemostasis is reduced with metal clip-based and suture-based VCDs when compared with extrinsic (manual or mechanical) compression
