Current Indications and Results of Cerebral Angioplasty
Balloon angioplasty was first made possible by advances in micro-catheter technology and neurointerventional imaging. Zubkov et al. reported the first use of balloon angioplasty for cerebral vasospasm in humans in 1984 . Subsequent reports by others confirmed the results that vasospasm of the cerebral arteries induced by subarachnoid hemorrhage could be successfully treated by cerebral angioplasty with micro-balloon catheters [3, 6]. These initial case series reported immediate reversal of angiographic vasospasm as well as sustained improvement in vessel caliber as measured by transcranial Doppler and improvements in cerebral blood flow. Improvements in neurological deficits caused by vasospasm were also reported. Initial reports emphasized the need for careful selection of patients and also reported several associated complications including vessel occlusion, rupture of unsecured aneurysms as well as re-perfusion hemorrhage.
