What is endovascular coiling?
Endovascular coiling is a minimally invasive medical procedure used to treat brain aneurysms, a potentially life-threatening condition. It is a technique performed by an interventional neuroradiologist or neurosurgeon, usually in a specialized angiography suite.
During endovascular coiling, a thin, flexible catheter is inserted into an artery (typically in the groin area) and navigated through the blood vessels to reach the site of the brain aneurysm. Using real-time X-ray imaging guidance called fluoroscopy, the catheter is carefully maneuvered to the aneurysm location.
Once in position, tiny platinum coils, often referred to as “microcoils,” are inserted through the catheter and released into the aneurysm. These coils have a complex shape and are specifically designed to promote blood clotting and prevent rupture of the aneurysm. By filling the aneurysm with coils, blood flow is diverted away from the weakened vessel walls, reducing the risk of rupture and subsequent bleeding.
The coils used in endovascular coiling procedures are typically made of platinum or a platinum alloy, which is a soft and flexible material that allows them to conform to the shape of the aneurysm. Some coils are coated with a bioactive material to encourage a more rapid and stable blood clot formation within the aneurysm.
Endovascular coiling offers several advantages over traditional open surgical methods, such as craniotomy. It is less invasive, requires a smaller incision, and often leads to shorter hospital stays and faster recovery times. However, not all aneurysms are suitable for endovascular coiling, and the decision on the most appropriate treatment approach depends on various factors, including the size, location, and shape of the aneurysm, as well as the patient’s overall health.
After the coiling procedure, patients typically undergo follow-up imaging, such as angiography or magnetic resonance angiography (MRA), to assess the stability and effectiveness of the treatment. In some cases, additional coiling procedures or other interventions may be necessary.
It is important to note that endovascular coiling is a specialized medical procedure that requires a highly skilled and experienced medical team. If you suspect you have a brain aneurysm or have been diagnosed with one, it is crucial to consult with a qualified healthcare professional who can provide a thorough evaluation and recommend the most appropriate treatment options based on your individual case.

Why might I need endovascular coiling?
There are several reasons why you might need endovascular coiling as a treatment option for a brain aneurysm. Here are some common indications for undergoing this procedure:
Presence of a Brain Aneurysm:
If you have been diagnosed with a brain aneurysm, your healthcare provider will consider various factors to determine the best treatment approach. Endovascular coiling may be recommended if the aneurysm is deemed suitable for this minimally invasive procedure.
In cases where a brain aneurysm has ruptured, urgent treatment is necessary to prevent further bleeding and potential complications. Endovascular coiling may be chosen as a primary treatment option if the aneurysm characteristics and the patient’s overall condition are favorable for this approach.
Certain characteristics of an aneurysm make it more prone to rupture, such as large size, irregular shape, or location in a critical area of the brain. If your aneurysm carries a high risk of rupture, endovascular coiling may be recommended as a preventive measure to reduce the risk and protect against potentially life-threatening bleeding.
Pre-existing Medical Conditions:
Your healthcare provider will consider your overall health and medical history when determining the most suitable treatment option. If you have pre-existing conditions that make open surgery (craniotomy) more risky, endovascular coiling may be preferred due to its minimally invasive nature and lower associated risks.
Personalized Treatment Plan:
The decision to undergo endovascular coiling is highly individualized and based on a thorough evaluation of your specific case. Your healthcare provider will take into account factors such as the aneurysm’s size, location, and shape, as well as your age, overall health, and personal preferences. They will discuss the treatment options with you and recommend the most appropriate approach tailored to your unique circumstances.
It is essential to have a comprehensive discussion with your healthcare provider or a specialist in interventional neuroradiology or neurosurgery. They will explain the benefits, potential risks, and expected outcomes of endovascular coiling based on your specific condition. This will help you make an informed decision about your treatment plan and ensure the best possible care for your brain aneurysm

What are the risks of endovascular coiling?
If you are pregnant or think you may be pregnant, you should tell your healthcare provider.
There is a risk for allergic reaction to the dye injected to allow the aneurysm to be viewed on X-ray. People who are allergic to or sensitive to medicines, contrast dye, or iodine should tell the radiologist or technologist. People with kidney failure or other kidney problems should tell the radiologist.
People who take anticoagulant (blood-thinning) medicines, such as aspirin, warfarin, clopidogrel, or others, should tell their healthcare providers before the procedure. These medicines may be stopped for one or more days before the procedure.
Because the procedure involves the blood vessels and blood flow of the brain, there is a risk for complications involving the brain. These complications may include:
>Loss of consciousness
>Stroke or transient ischemic attack (TIA, a temporary stroke-like condition)
>Paralysis of one half of the body
>An area of swelling caused by a collection of blood (hematoma)
>Loss of the ability or speak or the ability to understand speech (aphasia)
>Rupture of unruptured aneurysm
>Higher chance of an aneurysm recurring
There may be other risks depending on your specific medical condition. Discuss any concerns with your
healthcare provider before the procedure.
How do I get ready for an endovascular coiling?
Preparing for an endovascular coiling procedure involves several steps to ensure that you are ready for the intervention. Here are some general guidelines to help you prepare:
Consultation and Evaluation:
Schedule an appointment with your healthcare provider, who will likely be an interventional neuroradiologist or neurosurgeon. During this consultation, your medical history, imaging studies (such as angiograms or magnetic resonance angiography), and overall health will be assessed to determine if endovascular coiling is the appropriate treatment option for your brain aneurysm.
Follow any specific instructions provided by your healthcare team. These may include guidelines regarding medication management, dietary restrictions, and any necessary tests or evaluations before the procedure. It is essential to inform your healthcare provider about any medications, supplements, or allergies you have.
You may be required to undergo additional diagnostic tests before the procedure, such as blood tests, electrocardiogram (ECG), or chest X-rays. These tests help evaluate your overall health and ensure you are prepared for the procedure.
Fasting: Typically, you will be instructed to avoid eating or drinking anything for a certain period before the procedure. This fasting period helps minimize the risk of complications during the intervention, particularly if general anesthesia or sedation is used.
Arrangements for Transportation:
As endovascular coiling involves the use of sedation or anesthesia, it is crucial to arrange for someone to accompany you to and from the hospital or clinic. You may not be able to drive yourself immediately following the procedure due to the effects of sedation.
Bring any necessary personal items, such as identification, insurance information, and a list of medications you are currently taking. It is also advisable to wear loose, comfortable clothing and remove any jewelry or accessories before the procedure.
Discussion and Consent:
Your healthcare provider will discuss the procedure with you, including the benefits, risks, and potential complications. Take this opportunity to ask any questions or address concerns you may have. Once you understand the procedure and its implications, you will be asked to provide informed consent for the intervention.
