Coil Embolization
What is it?
Coil embolization is a minimally invasive procedure that uses strategically placed metal coils to block off abnormal bulges in blood vessels called aneurysms. An aneurysm is a weakened wall in an artery, which if it ruptures, can cause life-threatening brain damage or bleeding. The process involves threading a small flexible tube called a catheter into blood vessels, and then plugging up abnormally large areas with very small soft platinum metal coils.
What is Coil Embolization Used For?
Coil Embolization is commonly used to treat:
- Cerebral Aneurysms: Aneurysms in the brain that, if ruptured, can cause life-threatening bleeding.
- Peripheral Aneurysms: Aneurysms located in other parts of the body, such as the digestive tract.
What to Expect During Coil Embolization?
A coiling procedure, performed by a neurosurgeon or interventional radiologist under general or local anesthesia, involves inserting a catheter into an artery and guiding it to the aneurysm using X-ray imaging. Coils are deployed to seal off the aneurysm, preventing rupture. After sealing the aneurysm, the catheter is removed, and the site is dressed to stop bleeding.
Benefits of Coil Embolization
- Minimally Invasive: Unlike open surgery, coil embolization is performed from within the blood vessel, reducing recovery time and potential complications.
- Reduced Risk of Rupture: By sealing off the aneurysm, the procedure significantly lowers the risk of rupture and subsequent bleeding.
- Shorter Recovery Time: Patients often experience quicker recovery compared to open surgery.
