RESUMEN
Objective:To evaluate the safety and efficacy of intra-arterial tirofiban infusion during endovascular reperfusion therapy in patients with acute cardiogenic cerebral embolism.Methods:Clinical data of 72 patients with acute cardiogenic cerebral embolism caused by large artery occlusion were retrospectively analyzed in Department of Neurology, Strategic Support Force Medical Center from August 2015 to August 2020.Among those, 52 patients were treated with intra-arterial tirofiban, the other 20 patients were treated with control medication. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality were evaluated and compared in two groups.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in tirofiban group was higher than that in control group (92.3% vs. 75.0%), but the difference was not statistically significant ( P=0.104). At 90 days after operation, the rate of patients with good prognosis (mRS≤2) in tirofiban group (61.5%) was significantly higher than that in control group (35.0%) ( P<0.05). The incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusion:Intra-arterial tirofiban infusion in patients with acute cardiogenic cerebral embolism is effective and feasible, which improves the prognosis without increasing the risk of intracranial bleeding complications.
RESUMEN
Objective : The objective of this study was to assess the safety and efficacy of left atrial appendage (LAA) amputation during cardiovascular surgery. Methods : Fifty-seven patients underwent LAA amputation using a stapler from 2016 to 2017. The presence of remnant LAA was estimated by transesophageal echocardiography (TEE). Results : All LAA amputations were performed with the heart beating, without collapse. Additional amputation for remnant LAA was required in 14 patients. Sutures were needed to control bleeding in 7 patients. There was one case in which the coronary artery ended up being clamped with the LAA. The average duration for LAA amputation was 6.1±3.2 (1.5-15.2) min. There were 25 cases with postoperative atrial fibrillation (POAF), one case of cerebral infarction without POAF and one case of re-exploration for bleeding. Three patients died during hospitalization. Conclusion : LAA amputation using a stapler does not require cardiac arrest, and rarely requires an extended operation time. However, sufficient caution is required as there is the possibility that the coronary artery is obstructed and that remnant LAA is present.

Objective To explore the efficacy and safety of Solitaire stents and the multi-mode vascular recanalization in the treatment of acute cerebral infarction. Methods Twenty-two patients with acute cerebral infarction, who were treated by Solitaire stents and the multi-mode vascular recanalization (research group) in our hospital from November 2014 to February 2017, were included in this study. Among them, 16 cases were combined with balloon dilation after arterial thrombosis, 4 cases were given stent implantation (3 cases were given Solitair stent and 1 case was given Apollo stent), and 2 cases were given arterial catheter directed thrombolysis. Eighteen patients with acute cerebral infarction who were treated only by Solitaire stent artery occlusion from October 2011 to October 2014 were used as control group. Data of the onset to the vagina vasorum time, the onset to the recanalization time, the revascularization of interventional therapy, the NIHSS scores at admission and discharge, mRS score after 90-day treatment, incidence rate and the mortality were compared between two groups. Results There were no significant differences in the durations from onset to the vagina vasorum and from the onset to the recanalization between the two groups. The recanalization was better in research group than that of control group (P<0.05). There were no significant differences in scores of NIHSS at hospital discharge and admission between two groups. The near-term treatment efficacy was similar in two groups. However, mRS score was significantly lower in the research group than that in control group after 90-day treatment (P<0.05). There were no significant differences in the symptomatic intracranial hemorrhage, high perfusion encephalopathy, the incidence rate and the mortality rate of the complications related to the operation between two groups of patients. Conclusion Solitaire stents and the multi-mode vascular recanalization can significantly improve the revascularization, the further clinical prognosis and the quality of survival in patients with acute cerebral infarction, which are safe and efficacy without increasing incidence rate and mortality rate of complications.

RESUMEN
Objective To explore the correlations of diffusion-weighted imaging (DWI) types and the degree of neurologic impairment in acute ischemic stroke patients with atrial fibrillation.Methods DWI images and National Institutes of Health Stroke Scale(NIHSS) of 186 patients with acute ischemic stroke patients with atrial fibrillation were collected retrospectively.The correlation of DWI features and NIHSS was analyzed.Results On DWI,all acute ischemic stroke patients with atrial fibrillation presented high signal intensity.Single cortex-subcortical infarction mostly appeared in the anterior circulation(94,50.5%);Multi-infarction commonly occurred in the posterior circulation(18,13.0%);The neurological deficit scores of subcortical-cortex infarction in the left anterior circulation(16.75±7.10) were higher than that in the right side(13.50±5.70)(P<0.05).The neurological deficit scores of cortex-subcortical infarction in the posterior circulation (6.38±2.03) were significantly lower than that in the multi-infarction (16.77±8.90) (P<0.05).Conclusion DWI types are valuable for etiological diagnosis in ischemic stroke.Combination with NIHSS score could provide a basis for clinical individual treatment programs selection and prognostic evaluation.
RESUMEN
Objective To evaluate the effect and safety of intravenous (IV) thrombolysis, intra-arterial (IA) thrombolysis and mechanical adjuvant intra- arterial thrombolysis (IA + MA) in treating cardiogenic cerebral embolism. Methods A total of 66 patients with cardiogenic cerebral embolism were randomly divided into IV group (n = 25), IA group (n = 18), IA + MA group (n = 23). The artery recanalization rate, NIHSS score, GCS score, BI excellent rate, symptomatic intracranial hemorrhage rate and mortality after different thrombolytic therapies were determined. The results were compared between each other among the three groups. Results In all three groups both the post-treatment NIHSS score and GCS score were significantly improved when compared with pre-treatment ones (P < 0.05). In IA + MA group the artery recanalization rate was 78.3%(18/23) and the BI excellent rate was 40%(10/25), which were significantly higher than those in IV group (P < 0.05). The symptomatic intracranial hemorrhage rate in IA group was 5.6%(1/18), which was strikingly lower than that in IV group (32%, 8/25). Analysis of the causes showed that the artery recanalization rate in patients with valvular heart disease or cardiac myxoma was rather lower, but the intracranial hemorrhage rate and mortality in these patients were much higher. Conclusion Thrombolytic therapy can improve neurological deficit in cardiogenic cerebral embolism, and the therapeutic effect of mechanical adjuvant intra- arterial thrombolysis is definitely better.

@#Objective To investigate the levels of CD62P expression on patients with acute thrombotic cerebral infarction （ATCI） or acute cardiogenic cerebral embolism (ACCE). Methods The levels of CD62P expression were detected with flow cytometry (FCM) in the blood of 35 patients with ATCI, 30 patients with ACCE, and 33 healthy controls. Results Comparing with the controls, the levels of CD62P expression on patients did not increase both in the ATCI group and the ACCE group. (F=1.12, F=1.59；P>0.05). Furthermore, there wasn't significant difference in the expressions of CD62P between the ATCI group and the ACCE group. Conclusion The expressions of CD62P do not increase on the patients with ATCI and ACCE, although it is one of the markers of platelets activation.
RESUMEN
Objective To study the etiology,clinical features and prognosis of cardiogenic cerebral embolism.Methods Cardiogenic cerebral embolism patients in the ward of Department of Cerebral vessels from April 2007 to December 2007 were registered prospectively,and then the clinical data of the patients after 3 months follow-up were analyzed.Results 72 patients were included,49 patients had atrial fibrillation.At the end of the 3 month-follow-up,15 patients were dead,the total mortality was 20.8%.25 patients must depend on others to live on.Conclusion Atrial fibrillation was the most common etiology of cardiogenic cerebral embolism.Internal carotid artery systerm was easier to form embolism than vertebrobasilar systerm.Compared with vertebrobasilar systerm,internal carotid artery systerm was much worse on nerve function impairment and prognosis.Positive measures must be taken to prevent and treat primary cardiopathy,and reduce the rate of cardiogenic cerebral embolism.
