OBJECTIVES: To analyze the risk factors for postoperative deep vein thrombosis (DVT) in neurosurgical patients to provide the basis for the prevention of postoperative DVT. METHODS: A total of 141 patients underwent neurosurgery were enrolled. Thrombelastography (TEG) test was performed before and at the end of surgery. According to whether there was DVT formation after operation, the patients were divided into a thrombosis group and a non-thrombosis group. -test and rank sum test were used to compare the general clinical characteristics of the 2 groups, such as age, gender, intraoperative blood loss, -dimer, intraoperative crystal input, colloid input, blood product transfusion, operation duration, length of postoperative hospitalization. The application of chi-square test and rank-sum test were used to compared TEG main test indicators such as R and K values between the 2 groups. Logistic regression was used to analyze the possible risk factors for postoperative DVT in neurosurgical patients. RESULTS: There were significant differences in postoperative TEG index R, clotting factor function, intraoperative blood loss, hypertension or not, length of postoperative hospital stay, and postoperative absolute bed time (all <0.05). Logistic regression analysis showed hypercoagulability, more intraoperative blood loss and longer postoperative absolute bed time were risk factors for DVT formation after craniotomy. CONCLUSIONS Hypercoagulability in postoperative TEG test of patients is an important risk factor for the formation of postoperative DVT after neurosurgery, which can predict the occurrence of postoperative DVT to some extent.

OBJECTIVETo investigate the incidence, case fatality and risk factors of acute cerebral arterial thrombosis complicated by multiple organ dysfunction syndrome (MODS).

METHODSA retrospective study was conducted in 830 patients with acute cerebral arterial thrombosis, among whom 89 also developed MODS.

RESULTSThe incidence of MODS in these patients was 10.7% with case fatality of 58.4%. The presence of concurrent infection and increased number of organ involved both resulted in higher case fatality. The preceding health status, number of failing organs and score of neurologic impairment were the main fetal factors according to logistic regression analysis.

CONCLUSIONMODS usually occurs in two weeks after the onset of acute cerebral arterial thrombosis. Prevention of MODS involves rigorous treatment of the compromised organs and comprehensive systemic therapy in addition to the management of the primary diseases.

BACKGROUND: The purpose of the current study was to investigate the incidence of preoperative deep vein thrombosis (DVT) after hip fractures in Korea. METHODS: In this prospective study, we enrolled 152 Korean geriatric patients who had suffered hip fractures due to a simple fall and were hospitalized between January 2013 and December 2013. There were 52 male and 100 female patients, and their mean age was 78.2 years. There were 96 trochanteric fractures and 56 femoral neck fractures. All patients were examined for DVT: 26 by ultrasonography and 126 by computed tomography venography. The patients having DVT underwent inferior vena cava filter insertion before the surgical intervention. RESULTS: Preoperatively, none of the patients had any signs or symptoms of DVT; however, 4 patients were identified as having asymptomatic DVT. The overall incidence of DVT was 2.6% (4/152). The mean time to arrival at emergency room after injury was 32.6 hours. Mean time elapsed to undergo surgery after hospitalization was 24.9 hours. The average time to hospitalization after injury was 237 hours for patients with DVT versus 27.5 hours for patients without DVT. DVT developed within 72 hours in two of the 137 patients (1.4%) and after 72 hours in two of the remaining 15 patients (13.3%) hospitalized. CONCLUSIONS: While the preoperative incidence of DVT after hip fractures was relatively low (2.6%) in the Korean geriatric population, we confirmed that getting no treatment within 72 hours after injury increased the incidence of DVT. Thus, we conclude from this study that a workup for DVT should be considered in cases where admission or surgery has been delayed for more than 72 hours after injury.

Over the past decade, there has been a substantial increase in the number of men who are treated with testosterone. Despite this increase in the use of testosterone, the risks of adverse cardiovascular events are unclear as meta-analyses have reported conflicting findings and no clinical studies have been large enough or long enough to adequately assess for cardiovascular risks. The goal of this paper is to review large prescription database studies of testosterone treatment and adverse cardiovascular events and mortality with the aim of providing some guidance for clinicians and researchers in this controversial area.

thrombosis in childhood cancers and other childhood diseases through the Korean Health Insurance Review and Assessment Service database.METHODS: Data were extracted from the Korean Health Insurance Review and Assessment Service database. Children and young adults from 1 month to 29 years of age were eligible, and 21,747 cases of VTE between January 2008 and December 2016 were identified.RESULTS: The VTE incidence was high in children younger than 1 year of age. After 1 year of age, its incidence decreased rapidly and gradually increased. The VTE incidence for children between 0 and 1 year of age was 10.23-fold higher than that for those between 1 and 5 years of age. Annual VTE incidence increased by year. The age-standardized annual incidence rates were 9.98 per 100,000 population in 2008 and 22.53 per 100,000 population in 2016. The age-standardized annual incidence rate increased 2.25-fold during the 8 years. The lower extremity was the most common site of venous thrombosis.CONCLUSION: The incidence of VTE in a population younger than 30 years was 13.11 per 100,000 persons in Korea. We found a bimodal age distribution of the VTE incidence with peaks at infancy and again after 16 years. The incidence of portal vein thrombosis was high in infants, and infection and malignancy were the most common comorbidities in patients with VTE.]]>

PURPOSE: Catheter direct thrombolysis (CDT) has been shown to be an effective treatment for deep venous thrombosis. The objective of the review is to improve safety and efficacy of the CDT by using ward based protocol, better able to predict complications and treatment outcome through monitoring of haemostatic parameters and clinical observation during thrombolysis procedure. MATERIALS AND METHODS: MEDLINE, EMBASE, CENTRAL and Web of Science were searched for all articles on deep venous thrombosis, thrombolysis and correlations of clinical events (bleeding, successful thrombolysis) during thrombolysis with hemostatic parameters to March 2016. The risk of bias in included studies was assessed by Cochrane Collaboration’s tool and Cochrane Risk of Bias Assessment Tool: for Non-Randomized Studies of Interventions. RESULTS: Twenty-four studies were included in the review and we found that improving safety and efficacy of CDT by using ward based protocol depending on eight factors; strict patient selection criteria, types of fibrinolytic drugs, mode of fibrinolytic drug injection, biochemical markers monitoring (fibrinogen, D-dimer, activated partial thromboplastin time, plasminogen activator inhibitor-1), timing of intervention, usage of intermittent pneumatic calf, ward monitoring and thrombolysis imaging assessment (intravascular ultrasound). These factors may help to improve safety and efficacy by reducing total thrombolytic drug dosage and at the same time ensure successful lysis. There is a marked lack of randomized controlled trials discussing the safety and efficacy of catheter direct thrombolysis. CONCLUSION: CDT can be performed safely and efficiently in clinical ward, providing that careful nursing, biochemical monitoring, proper selection and mode of infusion of fibrinolytic drugs, usage of Intermittent pneumatic calf and adequate thrombolysis imaging assessment are ensured.

Objective: To probe the incidence and risk factors for thrombosis in Chinese immune thrombocytopenia through a retrospective analysis of the inpatients referred to the Blood Disease Hospital, CAMS & PUMC. Methods: A retrospective survey of 3 225 patients with ITP from October 2005 to December 2017 was performed, the clinical data of the patients with thrombosis were collected to analyze the causes, diagnosis, treatment and prognosis. Results: A total of 46 patients experienced a thrombotic event with a prevalence of 1.43%(46/3 225 cases) with the median age of thrombosis as 54 years (26-83) years, the prevalence of thrombosis was 3.37% (40/1 187 cases) in>40 years old, which was significantly higher than 0.58% (6/1 030 cases) in those under 40 years old, in adults (P=0.00). There were 20 males and 26 females, there was no statistical difference in the incidence of thrombosis between males and females[1.53% (20/1 309) vs 1.36% (26/1 916), P=0.187]; The prevalence of arterial thrombosis was 1.12% (36/3 225) higher than venous thrombosis[0.22% (7/3 225), P=0.00]when 82.61%(38/46 cases) of patients with PLT<100×10(9)/L. Post-splenectomy are risk factors for thrombosis in ITP patients, P values was 0.022, There was no statistical difference in the presence or absence of thrombotic events whether received glucocorticoid or TPO/TPO-Ra treatment, the P values were 0.075 and 0.531, respectively. Conclusions: In Chinese population, ITP disease maybe with a higher risk of thrombosis, there was no positive correlation between thrombosis and platelet level; and had obvious age distribution characteristics. The history of tobacco, hypertension, diabetes and post-splenectomy are risk factors for thrombosis in ITP patients.

OBJECTIVESTo investigate the different effects of closed suction drainage and non-drainage for total knee arthroplasty(TKA) and to provide reference information for the choice of clinical treatment.

METHODSRandomized controlled trials (RCTs) of closed suction drainage versus non-drainage for TKA were collected from the Cochrane Library, PubMed, EMBase, Springer, CBM, CNKI, VIP and WANFANG database. Methodological quality of the RCTs was independently assessed using the Consolidated Standards of Reporting Trials (CONSORT) checklist. Data analysis was performed by RevMan Version 5.1.6 based on the methods recommended by the Cochrane Collaboration.

RESULTSTwenty-one RCTs without bias were finally enrolled, and 1920 enrolled knees were identified into drainage group (979 knees) and non-drainage group (941 knees). A lower incidence of soft tissue ecchymosis was demonstrated in the closed suction drainage group (OR = 0.30, 95%CI: 0.24 - 0.49); however, compared with the non-drainage group, more loss of blood (MD = 320.03, 95%CI: 235.31 - 404.76) and more need of homologous blood transfusion (OR = 1.83, 95%CI: 1.26 - 3.29) were found in the closed suction drainage group. In addition, there were no significant differences of postoperative infection (OR = 0.53, 95%CI: 0.22 - 1.32), deep venous thrombosis (OR = 1.00, 95%CI: 0.46 - 2.18), and the joint range of motion (MD = -0.04, 95%CI: -1.11 - 1.02) between the two groups.

CONCLUSIONBased on the current evidence, no obvious advantage is demonstrated for closed suction drainage, in comparison with non-drainage for TKA.

OBJECTIVETo identify the risk factors of deep venous thrombosis (DVT) in hospitalized patients with acute stroke, under a perspective case-control study.

METHODS488 cases with stroke, identified by CT or MRI and admitted to the department of neurology and neurosurgery in Beijing Chaoyang Hospital between December 2001 and December 2002 were consecutively studied. There were 328 male and 160 female patients (95.5% Hans) with a mean age of 65 +/- 11 years, ranging 22 - 93 years. The procedure of study would include: (1) General condition, possible risk factors, symptoms of DVT physical check-up to every eligible patient on first day of admission but the plasma concentrations of D-dimer (ELISA), thrombomodulin, antithrombin-III and blood routine examination were measured on the next morning. (2) The ultrasonography (US) was used for detecting both lower extremities at 7 - 10 days after the onset of stroke, and D-dimer and AT-III tests were repeated on the same or next day that the US was taken. (3) The ultrasound examination was repeated after a week in patients with high suspicion of DVT. (4) The therapy of stroke was recorded before the end of the study. Data of stoke patients with DVT was compared with those without DVT to identify the DVT risk factors. The effect of each variable on DVT was assessed by logistic regression analysis.

RESULTSThe prevalence of DVT was 21.7% among the patients. In multivariate analysis, age >/= 65 years old (OR = 1.655, 95% CI: 1.005 - 2.725), being male (OR = 1.993, 95% CI: 1.221 - 3.253), bedridden (OR = 3.275, 95% CI: 1.653 - 6.486) and DVT assessment scores >/= 2 (OR = 5.019, 95% CI: 2.685 - 9.381) were independently associated with DVT in all the stroke patients. Being male (OR = 2.828, 95% CI: 1.242 - 6.438), white blood cell count > 10.0 x 10(9)/L (OR = 2.032, 95% CI: 0.897 - 4.602) and DVT assessment scores >/= 2 (OR = 8.809, 95% CI: 3.081 - 25.188) were the independent risk factors of DVT in hemorrhagic stroke group. Age >/= 65 years old (OR = 2.167, 95% CI: 1.072 - 4.381), bedridden (OR = 3.008, 95% CI: 1.435 - 6.307) and DVT assessment scores >/= 2 (OR = 2.600, 95% CI: 1.077 - 6.278) were the independent risk factors of DVT in ischemic stroke group.

CONCLUSIONPatients hospitalized with acute stroke were under high risk of DVT. Data suggested that old age, female, bedridden and high DVT assessment scores >/= 2 were independent risk factors for DVT in acute stroke patients that called for supervision and prophylaxis on DVT.
