ObjectiveTo analyze the therapeutic effects of open surgery and endovascular treatment for mesenteric venous thrombosis.MethodsThe clinical data of 22 patients with mesenteric venous thrombosis from March 2005 to January 2014 were analyzed retrospectively. One patient underwent open surgery including removal of necrotic small intestine and thrombectomy of superior mesenteric vein immediately admission to the hospital. Five cases were treated with simple anticoagulation and cured. Sixteen cases received thrombolytic therapy after primary anticoagulant therapy.ResultsOne case who underwent open surgery died of multiple organ failure at 72 h after the surgery. Five cases who received simple anticoagulant reached clinical relief finally. Sixteen patients who received thrombolytic therapy achieved recanalization totally or partially. Three cases died during follow-up (3 months to 7 years, average) of which 1 died of recurrence of acute superior mesenteric venous thrombosis, 1 died of myocardial infarction, and 1 died of stroke.ConclusionsFor patients with symptomatic mesenteric venous thrombosis, if there is no intestinal necrosis, there will be encouraging results by interventional thrombolytic therapy. And the treatment effect needs further experience accumulation in more cases.
Objective To analyze the clinical features of patients with acute pulmonary embolism ( APE) with normal blood pressure and right ventricular dysfunction. Methods 130 hospitalized patients with normotensive APE between January 2009 and January 2012 were retrospectively analyzed. The patients underwent transthoracic echocardiography to determine if they were complicated with RVD. The clinical features, risk factors, diagnosis, and treatment were analyzed and compared between the normotensive APE patients with or without RVD. Results 41 normotensive APE patients with RVD were as RVD group, and other 89 patients without RVD were as non-RVD group. The incidences of syncope ( 34.1% vs. 7.8% ) , tachycardia( 41.4% vs. 21.3% ) , P2 hyperthyroidism( 46.3% vs. 25.8% ) , jugular vein filling ( 12.1% vs. 1.1% ) , and cyanosis ( 26.8% vs. 8.9% ) were all significantly higher in the RVD group than those in the non-RVD group ( P lt; 0.05) . Computed tomography pulmonary angiography ( CTPA) revealed that the incidences of thromboembolism involving proximal pulmonary artery ( 58. 3% vs. 8. 3% ) and thromboembolism involving lobar pulmonary ( 77.8% vs.51.2% ) were also higher in the RVD group ( P lt; 0.001, P = 0.025 ) . In the RVD group, the patients were assigned to received thrombolysis plus anticoagulation therapy, or anticoagulation therapy alone. The clinical indicators ( heart rate, PaCO2 , AaDO2 , SPAP, TRPG) were all statistically improved after thrombolysis or anticoagulation treatment ( P lt;0.001) . But compared with the patients who underwent anticoagulation therapy alone, the cost of treatment and the incidence of minor bleeding were significantly higher, and the levels of AaDO2 , SPAP and TRPG were statistically lower in the patients with thrombolysis plus anticoagulation therapy. Conclusions For APE patients with central pulmonary embolism demonstrated by CTPA, syncope, and tachycardia, transthoracic echocardiograph should be performed as early as possible to confirm RVD diagnosis. For normotensive APE patients with RVD, anticoagulant treatment can achieve higher efficacy of costeffectiveness ratio.
Substantial progresses have been made in cerebral vascular diseases in 2017. By retrospectively analyzing the clinical researches which Chinese experts participated in or were in charge of, this article briefly summarizes the update of stroke epidemiology, explorations of stroke-related risk factors, early management of acute stroke, secondary prevention and prognosis of stroke. These researches include the problems about the dose of thrombolysis medicine, new type of antiplatelet and anticoagulant drugs, prognosis of intracranial hemorrhage and signs of intracranial hematoma enlargement, which have close connection with clinical work and are valuable in practice.
Objective To compare the efficacy of reteplase and ateplase in the treatment of acute massive pulmonary thromboembolism ( PTE) in emergency. Methods From January 2005 to December 2009,42 patients with acute massive PTE were treated by intravenous thrombolysis with reteplase or ateplase. The thrombolysis efficacy, bleeding incidence and mortality were measured. Results In the reteplase group, the emergency thrombolysis effective rate was 88. 9% among 18 patients. Mild bleeding occurred in 3 patients,moderate bleeding in 1 patient, and 2 cases died in hospital. In the ateplase group, the emergency thrombolysis effective rate was 75% among 24 patients. Mild bleeding occurred in 3 patients, moderate bleeding in 2 patients, and 3 cases died in hospital. The thrombolysis effective rate, bleeding incidence and mortality had no significant difference between the two groups. Conclusion Both the reteplase and ateplase thrombolysis therapy are safe and effective in the treatment of acute massive PTE, but reteplase thrombolysis therapy is more convenient in emergency.
ObjectiveTo systematically review the efficacy of early use of heparin for thrombolytic therapy in patients with acute myocardial infarction (AMI). MethodsThe Chinese databases involving VIP, CNKI, WanFang Data, CBM and foreign language databases including PubMed and The Cochrane Library (Issue 1, 2013) were electronically searched from inception to January 2013. Randomized controlled trials (RCTs) on early use of heparin in the treatment of AMI were included. Two reviewers assessed the quality of each trial and extracted data independently according to the Cochrane Handbook. RevMan5.2 software was used for statistical analysis. ResultsA total of 23 RCTs involving 2 697 patients were included. The results of meta-analysis showed that the heparin group was superior to the control group in increasing of the rate of coronary artery recanalization, decreasing the time of recanalization, reducing the rate of re-infarction and the death rate, and decreasing the time of ST-T fell for 50%, the time of enzyme peak showed and the time of chest pain relief. There had no significant difference observed in the incidence of adverse reaction between the two groups. ConclusionIt is effective to use heparin before thrombolytic therapy in AMI.

Objectives To study the relationship between matrix metalloproteinase-9 (MMP-9) and hemorrhagic transformation (HT) in ischemic stroke patients and provide evidence for the further clinical studies, thrombolytic therapy selection, and application of MMP inhibitors to clinical practice to extend the windows for thrombolytic therapy. Methods The studies on relationship between MMP-9 and hemorrhagic transformation in ischemic stroke were identified, in which HT was followed-up based on plasma level of MMP-9 or comparison of plasma level of MMP-9 was conducted based on HT or not, regardless of language of publication and type of design. MEDLINE (1966-Jan. 2006), EMBASE (1966-Apr. 2006), CNKI (1977-Feb.2006), and Wanfang database (1989-2005) were searched and the references lists of eligible studies were manually searched. Two reviewers independently evaluated the quality of studies and extracted data. The data were analyzed using the RevMan 4.2. and SPSS11.0 softwares. Results Six trials fulfilled the inclusion criteria, including 558 patients, 130 of them developed hemorrhagic transformation. The heterogeneity between studies was statistically significant; (Plt;0.0001). We didn’t pool the data of studies of plasma MMP-9 level. Most of the studies showed that the plasma MMP-9 level in HT or in a certain type of HT was higher than that in non-HT patients. The result of subgroup analysis showed that the plasma MMP-9 level was independently associated with HT, summary OR=14.45, 95%CI (4.90, 43.65). Conclusions The values of plasma MMP-9 in HT or in a certain type of HT are higher than that in non-HT. MMP-9 may independently be a risk of hemorrhagic transformation. The sample size of the included studies is small. So the conclusions need to be confirmed with further studies.
