A stereotactically guided operation was performed in two cases of deep-seated aneurysms which were difficult to be obliterated by the usual method.
One aneurysm was located in the peripheral region of the right posterior cerebral artery, and the other was in the superolateral region of the right lateral ventricle.
The target point was determined on the aneurysm and the needle was introduced into the brain up to the point about five milimeter to the target, and indigocarmine was injected pulling out the probe. We sucked out the brain tissue along the track stained with indigocarmine. The aneurysms were resected after coagulating the parent arteries. Brain edema was mild on postoperative computed tomography.
We suggest that our technical procedure was eligible for the deep-seated peripheral aneurysm.
