Occlusive cerebral vascular diseases have been treated by means of extra-intracranial arterial by-pass. However, the occlusion due to an apparent embolus is excluded from indications for the by-pass surgery as well as the occlusion at the middle portion of middle cerebral artery (MCA) where perforating arteries branch.<BR>The authors presented three cases of middle cerebral artery endarterectomy (MEA) and two cases of embolectomy, performed on patients whose MCA occlusions were contraindicated for the by-pass surgery.<BR>Postoperative angiograms of these patients showed reperfusion of the perforating arteries and MCA in all cases. However, only two patients, who underwent embolectomy 6 and 12 hours after the onset of hemiplegia, improved remarkably postoperatively.<BR>Serious operative complications such as hemorrhagic infarction or severe brain edema were not encountered.<BR>Literatures were reviewed and a brief discussion was made with regard to the difference of incidence of hemorrhagic infarction and severe brain edema between clinical cases and experimental animals.
