Giant cerebral aneurysms may be treated through a variety of options, including aneurysm trapping with concurrent bypass. This video describes the case of a large, recurrent, left middle cerebral artery aneurysm that was treated using a high flow, radial artery bypass graft, from the external carotid artery to the left temporal M2 branch. A step-by-step operative description, with emphasis on proper microsurgical technique, is included. The video can be found here: http://youtu.be/9xTMC6InivQ .

Intraoperative rupture of an intracranial aneurysm is a potentially devastating but controllable complication. The authors have successfully used the previously described cotton-clip technique to repair tears at the necks of aneurysms. (1-4) A tear on the neck of the aneurysm is covered with a piece of cotton and held in place with a suction device. The cotton is then clipped onto the tear with an aneurysm clip, using the cotton as a bolster. This simple, effective method has been useful in repairing a partial avulsion of the neck of an aneurysm. (1 , 3) The video can be found here: http://youtu.be/nT86RYVQWpc .

Greater extent of resection (EOR) of low-grade gliomas is associated with improved survival. Proximity to eloquent cortical regions often limits resectability and elevates the risk of surgery-related deficits. ⋯ Intraoperative monitoring with direct cortical stimulation and subcortical stimulation enables surgeons to preserve essential functional tissue during surgery. Through tailored pre- and intraoperative mapping and monitoring the EOR can be maximized, with reduced rates of surgery-related deficits.

Clip reconstruction of an 8 cm giant internal carotid artery bifurcation aneurysm: microsurgical technique.
Thrombosed giant intracranial aneurysms usually present with symptoms and signs from their mass effect. Although multiple treatment options are available, direct clip reconstruction with thromboendarterectomy remains the gold standard. Here we present a 66-year-old man with seizure, aphasia and hemiparesis. ⋯ Although we prepared for bypass with the radial artery and/or the superficial temporal artery, we were able to clip-reconstruct the aneurysm without bypass. The patient improved upon his pre-morbid state after surgery and made an excellent recovery. The video can be found here: http://youtu.be/P_10hRQFuPo .
