Abstract
We developed a tailor-made method based on surgical simulation using three-dimensional (3D) imaging of individual patients to allow safe performance of aneurysm clipping surgery via keyhole mini-craniotomy. 3D images were reconstructed of the skin, skull, cerebral arteries and veins, and the aneurysm. The size, shape, and location of the scheduled keyhole and the patient’s head position were determined by virtual osteostomy technique. The site of opening of the sylvian fissure was also determined according to the spatial relationships between the aneurysm and sylvian veins. A total of 170 tailor-made clipping surgeries have been performed in 160 patients. Good recovery was seen in 98.8% of the patients, and the morbidity rate was low at 1.6%.
Detailed preoperative simulation allows the performance of safe keyhole clipping surgery.
