A case of internal carotid giant aneurysm successfully treated by a detachable balloon catheter, is reported.<BR>A 27-year-old female was admitted to our hospital on September 9, 1982, with chief complaint of double vision. Neurological examination at admission revealed abducens and trigeminal nerves paresis on the right side. Internal carotid angiograms showed a presence of giant aneurysm (2.8×2.8cm) originating from petrosal portion of the right internal carotid artery.<BR>On October 27, 1982, STA-MCA double anastomoses were performed to prevent ischemic episode during intravascular procedure. Under local anesthesia, the giant aneurysm was treated by the maneuver after Debrun on October 29, 1982. Initially the authors attempted to introduce the balloon into the internal carotid artery distal to neck of the aneurysm under an intention of treatment by trapping of aneurysmal neck. However, it was unsuccessful and neck of the aneurysm and the internal carotid artery proximal to the aneurysmal neck were eventually occluded by the initial balloon without complication. The initial balloon was detached after confirmation of no change of EEG, somatosensory evoked potential and neurological signs for 70 minutes. The second balloon was introduced into the internal carotid artery proximal to the first balloon for further assurance of interruption of carotid flow.<BR>The aneurysm was not visualized on postop erative angiography performed on December 8, 1983 and the right abducens and trigeminal nerves paresis subsided following intravascular balloon procedure.<BR>Advantages and problems of detachable balloon technique for treatment of giant aneurysm, are discussed.
