Abstract
Objective: To investigate the efficacy and safety of mechanical thrombectory with a tri-axial system of the solitaire AB stent through a Navien delivery catheter to treatment acute vertebrobasilar artery occlusion. Methods: The clinical data of 16 consecutive patients with acute ischemic stroke of vertebrobasilar artery occlusion treated with the Solitaire AB device from March 2016 to March 2018 in Department of Neurosurgery, the First Affiliated Hospital, Medical College of Shihezi University, were extracted and then retrospectively analyzed.Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after operation 1 weeks, measured by National Institute of Health stroke scale (NIHSS) score were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after operation. Results: There were 10 male and 6 female patients with a median age of 59 years (ranging from 45 to 78 years).Fourteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath mean time were 8.5 hours.The NIHSS score at 7 days was 13±7, which was significantly decreased compared to the admission NIHSS score 24±4 (P=0.000).No symptomatic intracranial hemorrhage case was found after operation.At 90 days, 8 patients achieved good outcome (mRS 0 to 2), one patient died (mRS 6),two patients moderately seriously disabled (mRS 4).Three patients resulted in moderate outcome (mRS 3).In 3 cases of death,2 patients died due to failure in recanalization,another patient died of severe pulmonary infection. Conclusion: The results suggest that this technique of a tri-axial system used of the Solitaire AB stent through a Navien delivery catheter can effectively retrieve clots from the occlusive artery and improves functional outcome in patients with acute ischemic stroke of vertebrobasilar artery.
