Analysis Of The Effect Of Solitaire AB Stent In The Treatment Of Acute Basilar Artery Occlusion

Objective: To investigate the efficacy,safety and prognostic factors of neurological function on Solitaire AB stent.Methods: All 10 cases were collected from the Department of Neurology,the First People’s Hospital of Huaihua city and the People’s Hospital of Hunan province during the period of 2017.9.30-2018.12.01.This study is a retrospective analysis of the clinical data and imaging data about solitaire AB stent in treatment of acute basilar artery occlusion.The age,sex,time of onset,admission,and the National Institute of Health stroke scale(NIHSS)score,admission to puncture time,puncture to recanalization time,preoperative The posterior circulation functional area was evaluated using the Alberta Stroke Program Early CT Score(PC-ASPECT);the case was typed by TOAST classification;the cerebral infarction was used immediately after thrombolysis.Thrombolysis in cerebral infarction(TICI)evaluated the recanalization of blood vessels.Relevant complications were recorded,including: symptomatic intracranial hemorrhage(defined as any type of intracranial hemorrhage with an increase in NIHSS score ≥ 4 points),cerebral palsy,and pulmonary infection.The prognosis was evaluated to 90 days after surgery using a modified Rankin scale(mRS).Result: After recanalization with the solitaire AB stent,the recanalization rate(TICI 2b-3)was as high as 80%.The reason for theunopened 2 cases was that the thrombus hardness was high.After repeated trials,the patient could not be re-admitted,and the patient’s condition was evaluated.There is a risk of rupture of the blood vessels.After treatment with antiplatelet aggregation,lipid-lowering,nutritional nerves and rehabilitation therapy,4 patients(40%)achieved a good prognosis(mRS ≤ 2).The mortality rate of this study was 40%(4/10),including 2 cases of large-area cerebral infarction;1 case of intracranial hemorrhage;1 case of death caused by pulmonary infection,no adverse events such as pseudoaneurysm,arterial dissection,hematoma at puncture site.There was a significant correlation between preoperative pc-aspect score and clinical prognosis(p<0.05),which was negatively correlated.The preoperative NIHSS score,onset to recanalization time were not significantly associated with clinical prognosis(p>0.05).Conclusions:(1)The recanalization rate of solitaire AB stent in the treatment of acute basilar artery is increased,indicating that the technology has a certain effect;(2)Compared with the extremely high mortality of acute basilar artery occlusion,shows that the treatment of acute basilar artery occlusion with solitaire AB stent can reduce mortality and improve patient outcome,but still requires large sample validation.(3)Preoperative use of pc-aspect score is an independent influencing factor for patient prognosis.
