Stent-assisted angioplasty of cerebral arteries for the treatment symptomatic vasospasm
The objective is to describe clinical observations and literature data of possibility of using stent retriever technologies as a new treatment for cerebral vasospasm.Materials and methods. In the period from January 2017 to May 2019, 117 patients in the acute period of subarachnoid hemorrhage were treated at the Interregional Clinical Diagnostic Center (Kazan). Clipping was performed in 59 patients, endovascular occlusion in 58 patients. Vasospasm of varying severity estimated according to transcranial Doppler ultrasonography was observed in 115 (98.2 %) patients. Stent-assisted angioplasty was performed in three patients with vasospasm refractory to medical therapy using stent-retriever pRESET (Phenox, Germany).Results. The clinical efficacy of stent-assisted angioplasty with decreasing in speed indicators according to transcranial Doppler ultrasonography and neurological symptoms was achieved in all patients. No complications were observed.Conclusion. Stent-assisted angioplasty of cerebral arteries using stent retriever technologies is an additional option for the treatment symptomatic vasospasm in the acute period of subarachnoid hemorrhage.
