Methods:Clinical data of 7 patients with severe complications after LC from August 2007 to April 2009 were analyzed retrospectively. The clinical data was got from biliary department of West China Hospital. Results: Two cases of secondary common bile duct stone with acute suppurative cholangitis got cured by endoscopic sphincterotomy. Three cases of severe bile duct injury after LC had stricture of the hilar bile duct, and all of the cases were performed RouxenY hepaticojejunostomy with the diameter of stoma 2.03.0 centimeters. One case of strangulating intestinal obstruction was cured through jejunum endtoend anastomosis after cutting off the necrotic jejunum. All of the above 6 patients recovered well. Following up for 820 months, all lived well. One patient got pulmonary embolism after LC and dead of respiratory failure after active rescue. Conclusion: Carefully making operation and distinguishing the relationship of hepatic bile duct and common bile duct and the duct of gallbladder are the key points to prevent sever complications during LC. Reasonable and feasible treatment is the ensurement of increasing the living quality of the patients with sever complications after LC. And the surgeons of biliary department must have a correct attitude toward LC and should concern think highly during LC and should not pursue speed blindly. In necessary, the operation of LC should be turned into open cholecystectomy.
Objective To investigate the prognostic value of troponin I ( cTNI) , brain natriuretic peptide ( BNP) and D-dimer in acute pulmonary embolism ( APE) .Methods The plasma levels of cTNI, BNP, and D-dimer were measured in 98 consecutive patients with APE at the time of admission. The relationship between these parameters and mortality were evaluated. Results APE was diagnosed in 98 consecutive patients during January 2009 to December 2010, in which 49 were males and 49 were females. 14 ( 14. 3% ) patients died at the end of follow-up. The patients with positive cTNI tests had more rapid heart rates, higher rate of syncope, cardiogenic shock and mortality than the patients with normal serumcTNI. However the age and blood pressure were lower in the patients with abnormal serum cTNI ( P lt; 0. 05) . A receiver-operating characteristic curve analysis identified BNP≥226. 5 ng/L was the best cut-off value ( AUC 0. 829, 95% CI 0. 715-0. 942) with the negative predictive value of 97. 1% for death. The mortality of the patients whose serum D-dimer level ranging from 500 to 2499 ng/mL, 2500 to 4999 ng/mL, and ≥5000 ng/mL was 7. 8% , 12% , and 41. 2% , respectively ( P = 0. 009) . Upon multivariate analysis, cardiogenic shock ( OR=2. 931, 95% CI 0. 828-12. 521, P =0.000) , cTNI≥0. 3 ng/mL ( OR=1. 441, 95% CI 0. 712-4. 098, P = 0. 0043) , BNP gt; 226. 5 ng/L ( OR = 1. 750, 95% CI 0. 690-6. 452, P = 0. 011) and D-dimer≥5000 ng/mL( OR = 1. 275, 95% CI 0. 762-2. 801, P = 0. 034) were independent predictors of death. Conclusions Combined monitoring of cTNI, BNP or D-dimer levels is helpful for prognosis prediction and treatment decision for APE patients.
ObjectiveTo investigate diagnostic and prognostic value of pulmonary embolism severity index (PESI), troponin I (cTnI) and brain natriuretic peptide (BNP) in patients with acute pulmonary embolism (APE). MethodsA total of 96 patients confirmed with APE were collected from January 2010 to January 2013, and 50 cases of non-APE controls were also selected in the same period. According to the PESI scores, patients were divided into low-risk, mid-risk, and highrisk group. According to the results of cTnI and BNP, patients were divided into positive group and negative group. Then, we evaluated the diagnostic and prognostic value of the PESI score, cTnI and BNP for patients with APE. ResultsFor the APE patients, the higher the risk was, the higher the constituent ratio of massive and sub-massive APE was (P<0.01). In the cTnI positive group, massive and sub-massive APE accounted for 82.9%, and in the cTnI negative group, non-massive APE was up to 81.9%; in the BNP positive group, massive and sub-massive APE accounted for 73.3%, and in the BNP negative group, non-massive APE was up to 86.3%. The patients with positive cTnI and BNP had a higher rate of right ventricular dysfunction, cardiogenic shock and mortality than the negative group (P<0.01). ConclusionThe combined detection of cTnI, BNP and PESI score is important in the diagnosis and risk stratification in APE patients.
ObjectiveTo evaluate the predictive value of the high-sensitivity cardiac troponin I (hs-cTnI) in patients with acute pulmonary embolism (APE). MethodsIn a retrospective cohort study,272 consecutive patients with APE were reviewed and the 30-days death and in-hospital adverse events were evaluated. The patients were classified according to hs-cTnI value into a high hs-cTnI group and a low hs-cTnI group. The simple pulmonary embolism severity index (sPESI) was used for clinical risk determination. The adverse event was defined as intravenous thrombolytic therapy,noninvasive ventilator support to maintain oxygen saturation >90% and suffered with severe complications. The correlations of hs-cTnI with sPESI score,30-days adverse events and mortality were analyzed. The Kaplan-Meier curves and the log-rank test were used to compare time-to-event survival. Stepwise multivariate logistic regression analysis models were used to determine the incremental prognostic value of sPESI score and hs-cTnI. ResultsThe incidence of 30-day death (6.1%),renal failure (14.6%),bleeding (13.4%) and thrombolytic therapy (7.9%) were higher in the high hs-cTnI group than those in the low hs-cTnI group (P values were 0.009,<0.001,0.018 and 0.003,respectively). The patients with sPESI ≥1 and low hs-cTnI had greater free adverse events survival (P=0.005). hs-cTnI provided incremental predictive value for in-hospital adverse events,beyond the sPESI score (P<0.001). Conclusionhs-cTnI has excellent negative predictive value of APE prognosis,especially when used combined with sPESI score.
Objective To describe the clinical profiles of cardiac arrest due to fatal pulmonary embolism (FPE), and review the literature on FPE diagnosis and treatment. Methods The clinical profiles of two cases with cardiac arrest for FPE were presented. A systematic search of Medline (1950 - 2014) and EMbase (1980-2014) was conducted to identify studies that investigated the use of thrombolytic medications to treat cardiac arrest for FPE. Results The fatal event of two patients occurred after surgery. Both of them survived with cardiopulmonary resuscitation and administration of thrombolysis and anticoagulation, but one of them had major bleeding during anticoagulation. Six articles were found involving 72473 cases of cardiac arrest due to pulmonary embolism (PE) or unstable massive PE. The thrombolytic agents were recombinant tissue plasminogen activator or streptokinase, but the administration and dose of thrombolytic agents were unclear. Overall, administration of thrombolytics can shorten the time to return of spontaneous circulation and improve the survival rate. There was, however, an increased risk of bleeding events following administration of thrombolytics. Conclusions Because of the high mortality of cardiac arrest for FPE, the clinician should correctly identify patients with a high likelihood of FPE. Early use of thrombolytics is very important and can potentially improve patient outcomes.
ObjectiveTo investigate the difference in fibrinogen and D-dimer (D-D) level among pulmonary embolism patients with different risk stratification. MethodsSixty pulmonary embolism patients admitted during January 2013 and January 2014 in our hospital were retrospectively analyzed.The general clinical data were gathered, and the patients were divided into a high-risk group (n=19), a moderate-risk group (n=21), and a low-risk group (n=20) according to the 2008 ESC Guidelines on the diagnosis and management of acute pulmonary embolism.Fourteen patients admitted simultaneously with dyspnea and chest pain without pulmonary embolism were randomly recruited as a control group.The plasma levels of fibrinogen and D-D were detected and compared between these groups. ResultsIn the pulmonary embolism patients, there were no significant statistical differences in general data between the patients with different risk degree.With the risk degree increased, the level of fibrinogen decreased and the level of D-D increased (P < 0.05).Compared with the pulmonary embolism patients, the level of fibrinogen was higher and the level of D-D was lower in the control group(P < 0.05).The level of fibrinogen was negatively correlated with the level of D-D with a correlation coefficient of-0.805. ConclusionsElevated fibrinogen is one of high risk factors of the pulmonary embolism. With the occurrence of pulmonary embolism, the level of fibrinogen becomes lower, suggesting the potential of fibrinogen as a indicator for pulmonary embolism diagnosis and risk stratification.
ObjectiveTo investigate therapeutic strategy of acute pulmonary embolism. MethodsClinical data of 48 patients with acute pulmonary embolism who were treated in Affiliated Hospital of North Sichuan Medical College form January 2009 to May 2014 were analyzed retrospectively. ResultsOf the 48 cases, 14 cases of low risk (low risk group) were treated with anticoagulation, 24 cases of middle risk (middle risk group) were treated with anticoagulation and systematic thrombolysis or interventional therapy (local thrombolysis after thrombus fragmentation or thrombolytic catheter placement in pulmonary artery), 10 cases of high risk (high risk group) were treated with anticoagulation and interventional therapy. In low risk group, 12 cases (85.7%) were cured and 2 cases (14.3%) were markedly effective, and total effective rate was 100%. In middle risk group, 16 cases (66.7%) were cured and 8 cases (33.3%) were markedly effective, and total effective rate was 100%. In high risk group, 1 case died, 3 cases were cured, 2 cases were markedly effective, and 4 cases were better, and the total effective ratio was 9/10. All cases suffered from no complication such as hemorrhage of cerebral and digestive system. Forty-eight cases were followed up for 3-12 months, with a median time of 8 months. During the follow-up period, there was no complication occurred such as dyspnea, pulmonary embolism, placement change of filter net, and thrombosis. ConclusionsCorresponding therapeutic strategy would be taken according to risk stratification of the acute pulmonary embolism.
ObjectiveTo explore the early predictive value of Wells score and D-dimer for acute pulmonary embolism. MethodsEighty-two cases with acute pulmonary embolism comfirmed by computed tomography pulmonary angiography and (or) lung ventilation/perfusion scan were retrospectively studied from October 2013 to October 2014 in our hospital. Another 82 cases without acute pulmonary embolism in the chest pain center simultaneously were selected as control group. The data on admission were analyzed including Wells score, D-dimer, pH, PCO2, PO2, P(A-a)O2, brain natriuretic peptide, troponin I of two groups of patients. Relevant variables were selected by multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was made by sensitivity as the ordinate and 1 minus specificity as abscissa. The area under ROC curve (AUC) for relevant variables was calculated and the variable with higher AUC was selected. The best threshold, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were achieved from the ROC curves. ResultsThe multivariate logistic regression analysis showed that Wells score (OR=8.114, 95%CI 1.894-34.761, P=0.005) and D-dimer (OR=1.009, 95%CI 1.001-1.017, P=0.021) could predict APE early. The AUC, sensitivity, specificity, PPV, NPV of Wells score for the early prediction of patients with acute pulmonary embolism were 0.990, 50.0%, 100.0%, 100.0%, 66.7%, respectively. The AUC, sensitivity, specificity, PPV, NPV of D-dimer for the early prediction of patients with acute pulmonary embolism were 0.986, 95.1%, 97.6%, 97.5%, 95.2%, respectively. ConclusionWells score and D-dimer have high predictive value in patients with acute pulmonary embolism, and can be used in preliminary screening of acute pulmonary embolism in the emergency department.
ObjectiveTo explore the diagnostic value of the bedside echocardiogram for different risk stratification of patients with suspected pulmonary embolism. MethodsPatients with suspected pulmonary embolism in the emergency department of the Second Afflicted Hospital Xi'an Jiaotong University between July 2013 to December 2015 were included. According the Wells scores, they were divided into a low risk group (0-2 points), a intermediate risk group (3-6 points) and a high risk group (>6 points). All patients were underwent the bedside echocardiogram diagnosis, and the diagnostic value of the echocardiography for pulmonary embolism, the characteristics of different risk stratification of patients were analyzed by SPSS 18.0 software. Results115 patients with suspected pulmonary embolism were included, of which 20 were in the low risk group, 73 were in the medium risk group, and 22 were in the high risk group. The incidence of pulmonary embolism among the three groups was significantly different (high-risk vs. medium risk vs. low-risk: 90.9% vs. 76.7% vs. 15.0%, P<0.05), and the higher Wells scores gets, the greater possibility of having the pulmonary embolism. For the intermediate-risk group, the incidence of pulmonary embolism was significantly higher in patients with positive ultrasonic results than those with the negative ultrasonic results (87.3% vs. 44.4%, P<0.05). The predication of the ultrasonic positive and the negative in the low and high risk groups had no statistical differences (P>0.05). The result of echocardiogram showed that the right ventricular end-diastolic diameter, right ventricular end-diastolic transverse diameter, right atrial end-diastolic transverse diameter, RV/LV, RA/LA in the high risk group and the intermediate risk group were significantly higher than those in the low risk group (all P values <0.05). The right ventricular anterior wall activity in the low risk group was higher than that in the high risk group (P<0.05), but this difference was not found between the high risk group and the intermediate risk group. ConclusionBedside echocardiogram can be used as the diagnosis and differential diagnosis methods of suspected pulmonary embolism, and it has relatively higher diagnostic value for intermediate to high risk patients predicted by the Wells scores than low risk ones.
Objective To explore the clinical manifestations, computed tomography features, management and prognosis of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Methods The clinical data of patients with Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism admitted to Dongnan Hospital of Xiamen University from January 2012 to January 2017 were retrospectively analyzed. Results There were 8 patients who had Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Fever occurred in all patients, respiratory symptoms were noted in 5 patients, abdominal pain occurred in 2 patients, endophthalmitis coexisted in 1 patient, and diabetes mellitus coexisted in 7 patients, with no chest pain or hemoptysis. In biochemical indexes, procalcitonin increased most obviously. Microbiological studies revealed Klebsiella pneumoniae in 8 patients. Chest CT showed peripheral nodules with or without cavities, peripheral wedge-shaped opacities, a feeding vessel sign, pleural effusion, and infiltrative shadow. One patient finally deteriorated to acute respiratory failure, and died due to acute respiratory distress syndrome and/or septic shock. There was one case of spontaneous discharge. A total of 6 patients were improved and cured. Conclusions The clinical manifestation of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism is unspecific and misdiagnosis rate is relatively high. The major characteristics of chest CT scan include peripheral nodules with or without cavities, peripheral wedge-shaped opacities and a feeding vessel sign. Diagnosis and differential diagnosis can be made based on these features combined with clinical data and primary disease (liver abscess).
