Selective intra-arterial cold saline infusion combined with intravascular reperfusion for acute ischemic stroke with large artery occlusion: a preliminary safety and feasibility study / 国际脑血管病杂志

Objective To preliminarily investigate the safety and feasibility of intra-arterial cold saline infusion combined with intravascular reperfusion for acute ischemic stroke with large artery occlusion. Methods From March 2016 to March 2018, consecutive acute ischemic stroke patients with large artery occlusion within 8 h after onset admitted to the Department of Neurology, the People's Hospital of Longhua District, Shenzhen and recanalized successfully after endovascular treatment were enrolled. After recanalization, cold saline was infused through the guiding catheter via the ipsilateral guilty vessel (10 ℃, 33 ml/min for 30 min). Results A total of 20 patients were enrolled, including 15 males. Their median age was 67 years (interquartile range, 53-80 years). Fifteen patients were treated with thrombolysis. A median onset-to-needle time was 300 min (interquartile range, 260-360 min). During the infusion of cold saline, the lowest rectal temperature was only decreased 0. 1 ℃, but within 5 min after completion of perfusion, it returned to the temperature before perfusion. Complications associated with intra-arterial hypothermia were not observed. The median National Institutes of Health Stroke Scale score was significantly decreased from 21 (interquartile range 15-55) before needle to 15 (interquartile range 10-16; Z = -4. 549, P < 0. 001) at discharge. Conclusion Selective intra-arterial cold saline infusion combined with intravascular reperfusion for acute ischemic stroke with large artery occlusion is safe and feasible.

Application of selective intra-arterial brain hypothermia in acute ischemic stroke / 国际脑血管病杂志

Therapeutic hypothermia has been shown to improve neurological outcomes after global ischaemia/hypoxia in patients who have had cardiac arrest. Therapeutic hypothermia is one of the most extensively studied and influential therapeutic strategies of acute ischemic stroke. Previous studies of therapeutic hypothermia mainly focused on whole-body cooling. However, delayed induction and systemic complications have limited the clinical application of whole-body cooling. As a selective cerebral hypothermia, the selective intra-arterial brain hypothermia treatment has the characteristics of rapid and even induction of hypothermia, and less affecting the core body temperature. Therefore, it has become a promising treatment modality. This article reviews the application of selective intra-arterial brain hypothermia in acute ischemic stroke and its advantages and limitations in order to provide reference for further experimental studies and future clinical trials.

Cerebral protective effect of intracarotid propofol in patients undergoing resection of cerebral gliomas / 中华麻醉学杂志

Objective To investigate the cerebral protective effect of intracarotid infusion of propofol in patients undergoing resection of cerebral gliomas. Methods Sixty ASA Ⅰ- Ⅲ patients with cerebral glioma aged 40-64 yr weighing 48-73 kg were enrolled in this study. Forty patients undergoing resection of glioma under general anesthesia were randomly divided into 2 groups ( n = 20 each): intracarotid propofol group (group IA ) and intravenous propofol group (group Ⅳ). Twenty patients undergoing biopsy of glioma under local infiltration anesthesia with 2% lidocaine 15-20 md served as control group (group C). In IA and Ⅳ groups anesthesia was induced with TCI of propofol and remifentanil. Tracheal intubation was facilitated with rocuronium 0.6 mg/kg. The patients were mechanically ventilated. PErCO2 was maintained at 35-45 mm Hg. Anesthesia was maintained with TCI of propofol and remifentanil and intermittent iv boluses of rocuronium. In group IA internal carotid artery was cannulated after induction of anesthesia and propofol was administered by TCI via carotid artery while remifentanil was administered by TCI via peripheral vein. BIS was maintained at 40-60 during operation. ECG, MAP, HR, SpO2, PETCO2 and BIS were continuously monitored. MAP and HR were recorded before induction of anesthesia (T1) ,during skin incision (T2 ), at the end of operation (T3), during extubation ( T4 ). The glioma specimens were obtained for microscopic examination and determination of aquaporin 1 and aquaporin 4 ( AQP1, AQP4) expression by immunohistochemistry. Results MAP and HR were significantly decreased at T2 and T3 as compared with the baseline at T1 in group Ⅳ ( P ＜ 0.05), while there was no significant change in MAP and HR after induction of anesthesia in group IA ( P ＞ 0.05). The expression of AQP1 and AQP4 was down-regulated in IA and Ⅳ groups compared with group C (P ＜0.05). The propofol consumption during anesthesia was significantly less in group IA than in group Ⅳ (P ＜0.05). There was no significant diffe-rence in AQP1 and AQP4 expression, the amount of remifentanil and recuronium consumed and duration of operation betweenIA and Ⅳ groups ( P ＞ 0.05). Concltsion Intracarotid propofol can decrease the amount of propofol needed for maintenance of anesthesia as compared with intravenous administration and attenuate brain edema,indicating cerebral protective effect.

Efficacy and Safety of Hepatic Arterial Infusion of Fluorouracil with Leucovorin as Salvage Treatment for Refractory Liver Metastases from Colorectal Cancer

BACKGROUND/AIMS: Limited options remain for patients with metastatic colorectal cancer (CRC) after failure of standard systemic chemotherapy. Readministration of chemotherapeutic agents by hepatic arterial infusion (HAI) has the rationale of providing higher concentrations of chemotherapeutic agents to hepatic metastases. The present study was conducted to evaluate the efficacy and safety of HAI of fluorouracil with leucovorin (HAI 5-FU/LV) for patients with liver metastases from CRC. METHODS: Fourteen patients with liver metastases from CRC who received HAI 5-FU/LV after failure of systemic chemotherapy containing fluorouracil and leucovorin were identified and their medical records were reviewed. RESULTS: Of 10 patients evaluable for response, one partial response, six stable disease, and three progressive disease were reported. Additionally, the overall response and disease control rates were 7% and 50%, respectively. The median time to progression was 4.3 months (range, 2.9 to 5.6), to hepatic progression was 5.8 months (range, 4.7 to 6.9), and to extrahepatic progression was 5.8 months (range, 2.3 to 9.2). No grade 3/4 hematologic toxicities occurred and one case of abdominal pain and two cases of oral mucositis were the only grade 3 nonhematologic toxicities. Catheter-related complications occurred in three patients: one thrombosis, one infection, and one displacement. CONCLUSIONS: HAI 5-FU/LV was well tolerated and showed modest efficacy for patients with liver metastases from refractory CRC. Readministration of previously used chemotherapeutic agents via the hepatic artery could be an effective salvage option and warrants further investigation in a prospective trial.

Comparison the therapeutic effect of intra-arterial thrombolysis and intravenous thrombolysis for acute ischemic cerebral infarction within 6 hours of onset: A meta-analysis / 中国脑血管病杂志

Objective: To evaluate the efficacy and safety of intra-arterial thrombolysis and intravenous thrombolysis in the treatment of acute ischemic cerebral infarction through a meta-analysis. Methods: The literatures of the randomized controlled trials of using urokinase or recombinant tissue plasminogen activator for intra-arterial thrombolysis and intravenous thrombolysis in the treatment of acute ischemic cerebral infarction from January 1 ,2000 to August 5,2010 were reviewed. The primary outcome measures were the proportions of neurological improvement (basic cure + excellent results) in the intra-arterial thrombolysis and intravenous thrombolysis groups. The secondary outcome measures were the European Stroke Scale (ESS) scores after the treatment and the proportion of symptomatic intracranial hemorrhage. The meta-analysis software, RevMan 4. 2 was applied for pooling the data of all the findings. Two reviewers extracted the data independently. Results: A total of 11 articles either from foreign or domestic sources and 723 patients with acute cerebral infarction were included, in which 305 patients underwent intra-arterial thrombolysis and 418 underwent intravenous thrombolysis. Circled digit oneThe total improvement rate of the intra-arterial thrombolysis was 70. 92% and that of intravenous thrombolysis was 61. 29%. There was significant difference between them (χ2 =4. 895,P 0. 7 ). There was no significant difference in thrombolytic modes in the risk of complicating intracranial hemorrhage between the two groups (OR = 1. 12, 95% CI:0. 63 - 2.01,P = 0.69). Conclusion: The efficacy of intra-arterial thrombolysis for acute cerebral infarction is superior to that of intravenous thrombolysis, and both the incidences of symptomatic intracranial hemorrhage is comparable. A large, high-quality randomized controlled trial is need for further verification.

Pulmonary artery perfusion with cold modified Low- Potassium Dextran solution reduces lung injury in combined aortic and mitral valve replacement / 中国医师杂志

Objective This study was to evaluate the protective effect of pulmonary perfusion with cold modified low- potassium dextran (LPD) solution on lung function after cardiopulmonary bypass in combined aortic and mitral valve replacement. Method Twenty-four consecutive adult patients with combined aortic and mitral valve disease were divided into a control group ( n =14) and a perfused group ( n = 10). Cold modified LPD solution was infused to the main pulmonary artery in the protective group. PaO_2/FiO_2 were monitored at six different time points; preoperation, 0 hour, 1 hours, 2 hours, 6 hours and 12 hours after the termination of CPB. Concentrations of interleukin-6 and interleukin-10 in plasma were measured at four different time points; preoperation, 0 hour, 6 hours, and 12 hours after the termination of CPB. Result PaO_2/FiO_2 in the perfused group were increased more than that in the control group. The IL-6 and IL-10 increased in both groups after operations( P <0. 05). Patients of the perfused group showed significantly reduced IL-6 expression, compared with the control group ( P <0. 001), but the rising extents of IL-10 in the perfused group were higher than that in the control group ( P <0.001). Conclusion Pulmonary artery perfusion with cold modified LPD solution during cardiopulmonary bypass relieved lung injury in combined aortic and mitral valve replacement.
