Stent-assisted Coil Embolization For Basilar Artery Dissecting Aneurysm:Analysis Of Short-term Efficiency

Objective: To evaluate the safety and curative effect of stent-assisted coil embolization for basilar artery dissecting aneurysm(BADA),and to discuss the complications and prognosis.Methods: The clinical data of a total of 17 BADA patients,who were treated with stent-assisted coil embolization during the period from June 2012 to January 2017 at the First Teaching Hospital of Xinjinag Medical University,China,were retrospectively analyzed.The diagnosis was confirmed by MRI,CT angiography and DSA in all patients..Results: The patients were followed up for a mean of 7.3 months(3-9 months).Reexamination with DSA was performed in 14 patients,the results showed that improvement was obtained in 5 patients(35.7%)and stable disease was seen in 8 patients(57.2%),and recurrence occurred in one patient(7.1%).One patient refused to have angiography reexamination,and 2 patients died.After treatment,5 patients(29.4%)developed complications,among them 3 patients had pontine infarction(one patient died in 4 months after treatment;one patient suffered from hydrocephalus and had to receive ventricle-peritoneal cavity shunt treatment one month after stent-assisted coil embolization,the symptoms were remarkably improved in 5 months,and plain CT scan showed that the hydrocephalus was obviously improved;one patient had pontine and basal ganglia infarction and died of arrhythmia seven months after operation).During the follow-up period,modified Rankin Scale(mRS)score of 0-2 points were obtained in 10 patients(58.8%)and 3-6 points were obtained in 7 patients(41.2%).Conclusion: Stentassisted coil embolization can obstruct the false lumen and reconstruct the real lumen of basilar artery dissecting aneurysm.This technique is an effective therapy for BADA.
