Brain Aneurysm & AVM Surgery

Surgery for brain aneurysms and arteriovenous malformations (AVMs) aims to prevent rupture or hemorrhage, which can lead to life-threatening complications such as stroke or brain damage.

Brain aneurysm surgery typically involves two main approaches: clipping and endovascular coiling. Clipping involves placing a small metal clip at the base of the aneurysm to block blood flow and prevent rupture. Endovascular coiling, on the other hand, is a minimally invasive procedure where small coils are inserted into the aneurysm to induce clotting and seal off the weakened vessel.

For arteriovenous malformations, surgery aims to remove or obliterate the abnormal tangle of blood vessels to prevent bleeding. This can be achieved through open surgery, where the AVM is surgically removed or by endovascular embolization, where a glue-like substance or small coils are inserted into the abnormal vessels to block blood flow.

Both aneurysm and AVM surgeries require careful preoperative planning, often involving advanced imaging techniques such as angiography, to precisely locate and assess the size and shape of the lesion. During surgery, neurosurgeons work meticulously to preserve surrounding healthy brain tissue while addressing the vascular abnormality.

Postoperatively, patients are closely monitored for any signs of complications such as bleeding, stroke, or neurological deficits. With advancements in surgical techniques and technologies, outcomes for patients undergoing brain aneurysm and AVM surgery have significantly improved, reducing the risk of future hemorrhage and improving long-term prognosis.
