Coiling was introduced as a way of diagnosing and treating ruptured and unruptured brain aneurysms without the need for an open surgery called craniotomy. Coiling involves approaching the aneurysm from inside the blood vessel, so that there is no need to open the skull. Small metal coils are inserted into the aneurysm through the arteries that run from the groin to the brain. The coils remain in the aneurysm to stop blood from flowing into the aneurysm and therefore reduce the risk of a bleed or a re-bleeding.
Coiling of cerebral aneurysm procedure is similar to an angiogram and involves a very small tube called a catheter being guided from the groin up to the brain through the blood vessels. Using fluoroscopy guidance, the catheter is navigated to the area being examined. Once the target vessel is cannulated, contrast material is injected through the tube and images are captured on different angles. The coil is then carefully deployed on the aneurysm via fluoroscopy guidance. A repeat angiogram is done to check if the coil or coils deployed covered the target aneurysm. This is a much more complex procedure and is always carried out under general anesthesia.
The patient will be admitted at the hospital the night before the procedure usually at the Intensive Care Unit for proper monitoring of patients neurological status.
An informed consent will be secured from the patient or patient’s immediate family prior to procedure.
The doctor will instruct the patient not to eat or drink (NPO- nothing per orem) anything for usually 6-8 hours before the procedure.
The doctor will assess the patient’s physical and medical history and will review diagnostic tests done such as Cerebral Angiogram, CT Scan, CT Angiography or MRI result. Laboratory tests such as Creatinine, PT, APTT are usually requested prior to procedure. History of allergies on food especially seafood or medicines will be noted.
The patient’s groin will be shaved as an access during the procedure.
The anesthesiologist will give general anesthesia, so the patient will be asleep throughout the procedure.
On some cases, CP clearance will be required by the attending physician if the patient is at high risk of developing complications.
