Objectives: The frequency and predictors of recurrent symptomatic and angiographic vasospasm after angioplasty or intra-arterial chemical vasodilatation (IACV) in patients with subarachnoid hemorrhage (SAH) are not well characterized. Methods: A retrospective review of serial clinical and angiographic data was conducted between 7/2001-6/2008 on spontaneous SAH patients who underwent endovascular therapy for symptomatic vasospasm. Results: Of 318 SAH patients, symptomatic vasospasm occurred in 80 (25%) and endovascular intervention was performed on 69 (22%) patients. Of these 69 patients, all received IACV in 274 vessels and 33 also underwent angioplasty in a total of 76 vessels. Recurrent angiographic vasospasm occurred in the same vessel segment in 9/23 (39%) patients who received both angioplasty + IACV compared to 40/49 (82%) of patients who received IACV alone (P < 0.001). Recurrent symptomatic vasospasm occurred in 10/26 (38%) angioplasty + IACV patients compared to 28/37 (76%) patients who received IACV alone (P = 0.003). The modified-Fisher Score, A1 spasm, distal and multi-vessel vasospasm predicted recurrent angiographic spasm after IACV alone (P < 0.05). Procedural complications occurred in 4% of IACV alone patients and 6% of angioplasty + IACV patients (P = 0.599). Conclusions: Recurrent angiographic or symptomatic vasospasm is not uncommon after angioplasty + IACV, but appears to occur significantly less than after IACV alone, without any increase in procedural complications. © Springer-Verlag/Wien 2011.
