Coil Embolization of Cerebral Aneurysms

Ⅰ. What is coil embolization of cerebral aneurysm?

Coil embolization is a procedure used to treat aneurysms. This is done by placing a small, soft metal coil inside the aneurysm. This is used to stop blood flow and prevent the aneurysm from rupturing.

Ⅱ. Who needs coil embolization for cerebral aneurysm?

An aneurysm is a weakened area in a blood vessel that causes the blood vessel to dilate, dilate, or dilate. Although aneurysms are more common in older adults and women, they can occur at any age, regardless of gender.

In most cases, an aneurysm forms where a blood vessel divides into branches. Brain aneurysms are usually located at the base of the brain, just inside the skull. They usually measure between 1/8 inch and 1 inch.

Aneurysms can exist in a ruptured or unruptured state. A ruptured aneurysm is an aneurysm that has ruptured.

Ⅲ. What are the steps of cerebral aneurysm coil embolization?

1. Preparation procedure

Once the patient is placed in the correct position and anesthetized, some hair may be shaved at the insertion site, which is usually near the femoral artery, a blood vessel near the groin area.

2. Insert the coil

The neurointerventional doctor uses fluoroscopic imaging to insert a long, thin catheter into the femoral artery. Your doctor will then carefully guide the catheter to the aneurysm site in the brain. The neuro-interventional doctor then threads a thin wire through the catheter and coils the wire inside the aneurysm. This coil prevents blood from flowing into the aneurysm.

3. End the program

Once the wire is coiled, the neuro-interventional doctor will separate the neurovascular coil from the rest of the wire. The catheter and guidewire will then be removed, leaving the coil embolized in the aneurysm. The insertion site will then be bandaged.

4. After surgery

After this procedure, hospitalization will be required. The length of hospital stay depends on the location and severity of the aneurysm being treated but is usually one to several days.
