Detachable balloons were used for proximal occlusion of the internal carotid artery in 5 patients with intracavernous giant aneurysms. As a result, decrease in size of the aneurysm was observed in all patients on follow-up CT and MRI. Moreover, improved neurological symptoms were noted in 2 patients in whom treatment had been completed within 2 months after the onset of symptoms.
Before performing proximal occlusion, it is important to conduct a balloon occlusion test so as to accurately evaluate the availability of the occlusion of the internal carotid artery. In these patients who underwent simultaneous STA-MCA bypass surgery, none of them showed any late cerebral ischemic symptoms during follow-up observation up to 27 months.
Thus, the above procedure is considered to be a useful method of treatment for intracavernous giant aneurysms because it is a safe and easy method for reducing the size of aneurysms and for improving neurological symptoms.
