[The clipping off of a giant fusiform aneurysm and the formation of a middle cerebral artery lumen by using a method for the intravascular aspiration of blood from the aneurysm].

The paper presents a 36-year-old patient in whom giant fusiform aneurysm of the M1 segment of the MCA was successfully clipped using intravascular aspiration technique. EEG was intraoperatively monitored. At surgery, the lumen of the deformed M1 segment was newly shaped by a series of 3 fenestrated clips. Intravascular aspiration of blood from the ipsilateral ICA significantly helped decrease blood volumes within the aneurysm and its size which facilitated dissection and clipping of the aneurysm. Since intravascular aspiration have been previously used during surgery of giant and large paraclinoidal aneurysms, this case demonstrates the benefits of the technique in the surgery of aneurysms located in the areas other than paraclinoid one.
