Endovascular Coiling

What is an Endovascular Coiling Procedure?

The endovascular coiling procedure is performed by threading a thin catheter into a blood vessel, typically starting in the groin, and advancing it through the blood vessels until it reaches the aneurysm located in the brain. These tiny coils of platinum are placed directly into the aneurysm to fill it and seal it off, preventing any blood from entering the weakened portion of the blood vessel and therefore decreasing the possibility of a rupture. All of this process occurs guided by X-ray images in real-time, and the entire procedure is usually completed within two to four hours.

A simple explanation for patients

Simply put, endovascular coiling surgery means a surgeon threads a tiny tube through a blood vessel up to the brain and places small coils inside the bulge to block blood flow, preventing dangerous bleeding or rupture.

Why is Endovascular Coiling Surgery Needed?

This surgery is needed when an aneurysm, a weakened, balloon-like bulge in a brain artery, is detected and poses a risk of bursting, which can cause life-threatening bleeding. Coiling offers a less invasive alternative to open surgery, safely sealing the aneurysm and protecting brain function. Timely intervention greatly reduces the risks of stroke or permanent damage.

Common Reasons and Key Conditions Treated

• Burst or unruptured brain aneurysms.

• Aneurysms are too tricky for open surgery.

• Prevention of aneurysm rupture-related bleeding.

• Blood vessel malformations causing aneurysm risks.

Indications for Endovascular Coiling Procedure

Ideal candidates have cerebral aneurysms identified by imaging, with clinical features or size indicating risk of rupture, and are fit for minimally invasive procedures.

• Confirmed diagnosis of cerebral aneurysm via angiograms or MRI.

• Aneurysm size and shape are suitable for coiling.

• Presence of symptoms or high rupture risk.

• Good overall health status supporting endovascular intervention.

Who Should Avoid or Delay Endovascular Coiling Surgery?

Caution is warranted in patients with severe allergies to contrast dye, active infections, or unstable medical status. Your care team will evaluate each case carefully.

• Known allergy or intolerance to contrast materials.

• Uncontrolled bleeding or clotting disorders.

• Active systemic infections.

• Severe cardiovascular or respiratory compromise.

Preparing for Endovascular Coiling Surgery

• Preoperative imaging and neurological evaluation.

• Blood work and allergy testing for contrast agents.

• Discussion of anaesthesia options: general or conscious sedation.

• Guidance on fasting and medication adjustments before the procedure.

• Coordination of travel and accommodation for international patients.

What Will Happen During an Endovascular Coiling Procedure?

You will lie on an X-ray table, and anaesthesia will be administered according to your health status. After cleaning and numbing the groin or wrist area, the doctor will insert a catheter into a blood vessel and carefully guide it to the aneurysm. A microcatheter will then be navigated inside the aneurysm, where platinum coils will be released. Coils may be placed until the aneurysm is fully packed. The coils induce clotting to seal off the aneurysm. After confirmation of success through imaging, the catheter is removed, and pressure is applied to the entry site.

Step-by-Step Breakdown

• Positioning on the angiography X-ray table and administering anaesthesia.

• Preparing and numbing the catheter insertion site in the groin or wrist.

• Insertion of the guiding catheter and navigation to the cerebral aneurysm.

• Inserting a microcatheter inside the aneurysm sac.

• Deploying platinum coils to pack the aneurysm.

• Verifying aneurysm occlusion with contrast angiography.

• Removing catheters and applying pressure to the insertion site.

Recovery After Endovascular Coiling

Post-procedure, you will be monitored in an intensive care or stroke unit for neurological stability. Most patients stay in the hospital for several days. Careful control of blood pressure and activity restriction will be advised. Follow-up imaging will ensure lasting aneurysm closure. Rehabilitation and medical support continue as needed.

Risks & Complications

Risks include bleeding, vessel injury, coil migration, or incomplete aneurysm occlusion. Allergic reactions to contrast dye are rare but possible. Careful planning and experienced teams minimise these risks, ensuring patient safety.

Benefits of Endovascular Coiling Surgery

Endovascular coiling is less invasive than open surgery, involves shorter hospital stays, and offers rapid recovery. It effectively prevents aneurysm rupture and reduces stroke risk, significantly improving survival and quality of life.
