ObjectiveTo study the method with endoscope-assisted microsurgical technique through the supraorbital keyhole approach to treat aneurysms in the anterior circulation.MethodsAccording to preoperative diagnostic imagings, to work out of the individual operation planning. Skin incision was made in the eyebrow, and the diameter of supraorbital craniotomy was about 2 cm, endoscope-assisted microsurgical technique was used to clip aneurysm. The technique was used in the most recent 12 consecutive patients.ResultsFive different kinds of aneurysms in the anterior circulation were clipped through this method and 12 patients were cured. One patient, intraoperative accidental aneurysm rupture occurred. There were no approach-related complications.ConclusionsThis endoscope-assisted microsurgical technique via supraorbital keyhole approach is a safe, minimal invasive and effective way for the treatment of aneurysms in the anterior circulation, and there is more sufficient operating space.
