Coiling of Aneurysm (Endovascular Surgery)
A cerebral aneurysm is a weak or bulging area in the wall of a blood vessel in the brain that can rupture, causing life-threatening bleeding known as a subarachnoid hemorrhage. Early detection and timely treatment of an aneurysm are crucial to prevent rupture and neurological damage. Traditionally, aneurysms were treated through open brain surgery, but advances in endovascular neurosurgery now allow safer, minimally invasive procedures such as aneurysm coiling.
Endovascular coiling is a minimally invasive procedure used to treat certain brain aneurysms. It involves guiding a catheter through the blood vessels to place coils within the aneurysm, helping reduce blood flow into the aneurysm sac. This technique involves navigating a microcatheter through the blood vessels to the aneurysm site and deploying tiny platinum coils that fill the aneurysm, sealing it off from normal circulation and preventing rupture.
Treatment planning for brain aneurysms may involve endovascular procedures, open surgery, or other management strategies. The choice depends on factors such as the aneurysm’s location, size, rupture status, and the patient’s overall health. Each approach has potential benefits and risks, including the possibility of recurrence or bleeding, which should be discussed with the treating specialist.
Neuroimaging techniques support the assessment of brain aneurysms and help guide treatment planning. The choice of procedure depends on factors such as the aneurysm’s size, shape, location, and the patient’s overall health.
Clinical Management
Treatment begins with high-resolution CT angiography or Digital Subtraction Angiography (DSA) to evaluate the size, shape, and position of the aneurysm. Based on these findings, Dr. Rahul Gupta determines whether the patient is a candidate for endovascular coiling or surgical clipping.
During coiling, a thin catheter is inserted through a small puncture in the femoral or radial artery and guided up to the brain using real-time fluoroscopic imaging. Through this catheter, Dr. Gupta deploys soft platinum coils into the aneurysm sac. These coils induce clot formation, which effectively seals the aneurysm and prevents blood from entering it again.
This procedure avoids the need for open craniotomy, resulting in reduced pain, quicker recovery, and fewer complications. Most patients can return home within 2–3 days of the procedure. Follow-up angiographic imaging ensures that the aneurysm remains completely sealed and helps monitor for any recurrence.
Minimally invasive brain aneurysm treatment may involve endovascular coiling or other catheter-based techniques, depending on the aneurysm’s characteristics. The suitability of each approach and its potential risks vary by case.
