Objective To investigate the effect of hyperglycemia at admission in patients with acute ischemic stroke on endovascular treatment outcome.Methods From May 2012 to December 2016,200 consecutive patients with acute ischemic stroke (excluding patients with diabetes mellitus) underwent endovascular mechanical thrombectomy at the Department of Neurosurgery,the First People's Hospital of Changzhou were enrolled retrospectively.They were divided into either a hyperglycemia group (hyperglycemia was defined as glucose ＞7.8 nmol/L at admission,n =57) or a non-hyperglycemia group (n =143) according to the blood glucose levels at admission.The neurological function of the patients was evaluated by the National Institutes of Health Stroke Scale (NIHSS) at admission and discharge.The modified thrombolysis in cerebral infarction (mTICI) grade was used to evaluate the degree of recanalization.The modified Rankin scale (mRS) was used to evaluate the prognosis of the patients at 90 d after procedure.The general information of the patients were analyzed,including sex,age,past history,hospitalization time,onset to recanalization time (ORT),TOAST classification of cerebral infarction,and recanalization.The endovascular treatment outcomes of both groups were compared.Results (1) There were no significant differences in TOAST classification,age,hypertension history,atrial fibrillation history,stroke history,coronary heart disease history,ORT,NIHSS at admission between the patients of the two groups (all P ＞ 0.05).(2) There were no significant differences in days of hospitalization,mTICI grade,and number of thrombectomy between the patients of the two groups (P ＞0.05).(3) The discharge mortality and incidence of in-hospital neurological deterioration in the patients of the hyperglycemia group were 28.1％ (16/57) and 31.6％ (18/57) respectively,while those in the non-hyperglycemia group were 14.7％ (21/143) and 18.2％ (26/143) respectively.There were significant differences between the two groups (P =0.028 and 0.039 respectively).Conclusion Hyperglycemia at admission may have adverse effects on the prognosis in patients after receiving mechanical thrombectomy.

Objective To investigate the preliminary experience of mechanical thrombectomy with a tri-axial system of the Solitaire AB stent through a Neuro delivery catheter to treat intracranial large artery occlusion. Methods A tri-axial system was used to deliver the Solitaire AB stent through a Neuro delivery catheter to provide intracranial aspiration in close proximity to the stent. This technique was used in 1 case of acute middle cerebral artery occlusion and 1 case of acute basilar artery occlusion. Results Successful revascularization was achieved in these 2 cases. Thrombolysis in cerebral infarction (TICI)score was 3. The clot length of acute middle cerebral artery occlusion was 3 cm and the modified Rankin Scale (mRS)score of this case was 3 at 90 days follow-up. Another patient with acute bilateral vertebral occlusion was revealed successful recanalization by angiography. Conclusion The results suggest that this technique of a tri-axial system used of the Solitaire stent through a Neuro delivery catheter can effectively retrieve clots from the occlusive artery and minimize the chance of antegrade blood flow dislodging the thrombus.

Complex intracranial aneurysms refer to huge aneurysm, wide-necked aneurysm, fusiform aneurysm, microaneurysm, dissecting aneurysm and pseudoaneurysm.Endovascular interventional therapy is one of the safe and effective methods for intracranial aneurysms. However, the treatment is still limited by the morphology and is challenged by the recurrence for most of the complex intracranial aneurysms. The article reviews the treatment progress of complex intracranial aneurysms.
