Two patients had successful and uneventful PTA.Five patients had vasospasm,which resolved with local vasodilators in two and with repeat PTA in one.Vasospasm led to stoke in two patients.Compromise of perforating vessels and arterial dissection were associated with stroke in two patients.Intracranial PTA is technically feasible but associated with risks related to vasospasm,arterial trauma,and compromise of perforating vessels. |
