title: [Endovascular treatment of vasospasm].
abstract: Cerebral vasospasm remains a leading cause of heightened morbidity and mortality rates following aneurysmal subarachnoid hemorrhage despite the apparent benefit of recent medical therapeutics. Successful resolution of medically refractory angiographically demonstrated vasospasm with concomitant reversal of delayed neurological deficit has been observed after balloon angioplasty. Subsequent reports confirmed these encouraging results but also emphasized the limitations of the technique and the risks of complications. Intraarterial papaverine infusion has been performed for the treatment of diffuse cerebral vasospasm with controversial results and has also been combined with angioplasty either to facilitate balloon navigation or to treat arteries inaccessible to balloon catheterization. All these different endovascular approaches explain the confusion existing about the indications, timing and efficacy of the endovascular treatments. This article reviews several clinical and experimental studies dealing with these questions.
