Description

Appropriate surgical treatment for partially thrombosed giant cerebral aneurysms compressing the brainstem remains unclear. Between 2011 and 2015, 4 patients with progressive neurological deterioration due to these complex lesions underwent direct neck clipping followed via intraaneurysmal thrombectomy in our institution. Postoperatively, the aneurysm size immediately decreased significantly, in association with early significant improvement in the surrounding brainstem edema. All patients showed neurological improvement after surgery. Our experience introduces this technique as a safe and more durable treatment option for the management of partially thrombosed giant cerebral aneurysms, especially in critical locations that require prompt decompression of vital structures.
