1.Acute pulmonary embolism: the clinical conundrum.
Chinese Medical Journal 2012;125(2):352-366
Despite important advances in the diagnosis and treatment of acute pulmonary embolism (APE), assessment of risk and appropriate management of patients remains a difficult task in clinical practice. In addition to hemodynamic instability and critically clinical condition, acute right ventricular dysfunction (RVD) is a major determinant of in-hospital outcomes. The purpose of this review is to discuss the results of these recent developments. Some outcome evaluation, clinical assessment, and therapeutic implications are also included.

BACKGROUNDPulmonary-vein isolation (PVI) is currently used for the treatment of chronic and paroxysmal atrial fibrillation and a major risk of PVI is thromboembolism. The purpose of this study was to observe embolic event rate in patients with persistent or paroxysmal atrial fibrillation (AF) undergone PVI.
METHODSCircumferential PVI (CPVI) was performed in 64 consecutive patients with persistent AF (42 men, aged (60.0 +/- 9.1) years) and in 84 consecutive patients with paroxysmal AF (53 men, aged (61.4 +/- 9.3) years). Warfarin was administrated in all patients before ablation for at least 3 weeks ((5.2 +/- 2.6) weeks) and continued for at least 3 months post ablation with international normalized ratio (INR) of 2.0 - 3.0. During CPVI, intravenous heparin was given at a dose of 5000 - 8000 U or 75 - 100 U/kg, followed by 1000 U or 12 U/kg per hour.
RESULTSIn patients with persistent AF, 1 patient developed embolic event during ablation and 3 patients developed embolic events after ablation. In contrast, no thromboembolic event was observed in patients with paroxysmal AF (4/64 vs 0/84, P = 0. 033).
CONCLUSIONThromboembolic event rate related to CPVI is significantly higher in patients with persistent AF than that in patients with paroxysmal AF.

BACKGROUND:
The Previous study has indicated that the incidence of venous thromboembolism (VTE) after lung cancer surgery is not uncommon. The aim of this study is to analyze the risk factors of postoperative VTE in lung cancer patients and provide a clinical basis for further prevention and treatment of VTE.
METHODS:
This study was a single-center study. From July 2016 to December 2017, all patients with lung cancer who underwent surgery in our department were enrolled into this study. Except routine preoperative examinations, lower extremity Doppler ultrasound was performed in all patients before and after surgery to determine whether there was any newly developed deep venous thrombosis (DVT). Patients did not receive any prophylactic anticoagulant therapy before and after surgery. Patients were then divided into VTE group and control group according to whether VTE occurred after operation. Baseline data, surgical related data (surgery type, surgical procedure, etc.) and tumor pathological data (pathological type, vascular infiltration, pathological staging, etc.) were compared between the two groups.
RESULTS:
According to the inclusion criteria, a total of 339 patients undergoing lung cancer surgery were analyzed. There were 166 males and 173 females with an age range of 23-86 years. A total of 39 patients developed VTE after surgery, the incidence rate of postoperative VTE was 11.5%. Comparing the age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA), smoking status, underlying diseases, etc, there were no significant differences in other indicators except for significant differences in age; comparison between preoperative blood routine, blood biochemistry, coagulation, tumor markers, lung function, lower extremity venous ultrasound, preoperative carcinoembryonic antigen (CEA) levels, preoperative D-dimer levels, there were significant differences in lung function and lower extremity intermuscular vein expansion ratio. There were no significant differences in other indexes between the two groups. The duration of surgery, surgical procedure, bleeding volume, pathological type, pathological stage, vascular invasion, were compared between the two groups. There were statistical differences in surgical methods (thoracic vs thoracoscopic) and bleeding volume. There were no significant differences in other indicators. Univariate analysis showed that age, preoperative CEA level, preoperative D-dimer level, poor pulmonary function, lower extremity intermuscular vein dilation ratio, thoracotomy rate, length of surgery, and amount of bleeding were significantly risk factors (P<0.05). There were no significant correlations between pathological stage and pathological type and VTE. Multivariate logistic regression analysis showed that forced expiratory volume in one second (FEV1), surgical approach, and lower extremity intermuscular vein dilatation were independent risk factors for postoperative VTE in patients with lung cancer (P<0.05).
CONCLUSIONS
The results of this study suggest that FEV1, surgical procedures, and lower extremity intermuscular vein dilation are independent risk factors for postoperative VTE in patients with lung cancer.

OBJECTIVES:
To screen the risk factors for predicting venous thromboembolism (VTE) risk after hip fracture in the elderly, to establish a prediction model based on these factors, and to analyze its prediction efficacy.
METHODS:
A total of 52 hip fracture patients over 60 years old with VTE admitted to the Department of Orthopaedic Trauma, Xiangya Hospital, Central South University from March 2017 to April 2019 were selected as a thrombus group, and another 52 hip fracture patients over 60 years old without VTE were selected as a control group. The differences of hospitalization data and examination results between the 2 groups were compared. Logistic regression model was used to explore the influence of risk factors on VTE risk after hip fracture in the elderly and construct the prediction model based on these factors. The receiver operating characteristic curve was used to analyze the predictive effectiveness of model, Hosmer-lemeshow goodness of fit test was used to evaluate the fitting degree of prediction model.
RESULTS:
Univariate analysis showed that injury-admission interval, Caprini score, WBC count, platelet count, neutrophil count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammatory index (SII), and fibrinogen in the thrombus group were higher than those in the control group (all
CONCLUSIONS
SII, Caprini score, and injury-admission interval are independent predictors of VTE after hip fracture in the elderly. The prediction model based on these 3 factors has a good efficacy on the prediction of VTE risk, and could provide important reference for the prevention, management, and treatment of VTE after hip fracture in the elderly.

BACKGROUND:
Lung cancer is the first leading cause of morbidity and mortality among the malignant tumors, which has become a hot issue in current research. Clinically, lung cancer is divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) according to the pathological types. NSCLC includes adenocarcinoma, squamous cell carcinoma and other types of lung cancer, accounting for about 80% of all lung cancer. Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE), which is a recognized complication in lung cancer patients with higher morbidity and mortality. The aim of this study is to determine the incidence of DVT and reveal the risk factors for DVT in the postoperative patients with lung cancer.
METHODS:
We collected 83 postoperative patients with lung cancer admitted to the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital from December 2021 to December 2022. All these patients were examined by color Doppler ultrasound of lower extremity vein upon admission and after operation to analyze the incidence of DVT. In order to explore the possible risk factors for DVT in these patients, we further analyzed the correlations between DVT and their clinical features. At the same time, the changes of coagulation function and platelet were monitored to investigate the value of blood coagulation in the patients with DVT.
RESULTS:
DVT occurred in 25 patients after lung cancer operation, and the incidence rate of DVT was 30.1%. Further analysis found that the incidences of postoperative lower limb DVT were higher in lung cancer patients of stage III+IV or over 60 years of age (P=0.031, P=0.028). D-Dimer level in patients with thrombosis was significantly higher than that in non-thrombus patients on the 1st, the 3rd, and the 5th day after operation (P<0.05), and there was no significant difference in platelets and fibrinogen (FIB) (P>0.05).
CONCLUSIONS
The overall incidence of DVT in our center after lung cancer patients operation was 30.1%. Late-stage and older postpatients were more likely to develop DVT, and these patients with higher D-Dimer values should be considered the possibility of VTE events.

BACKGROUNDVenous thromboembolism is known to be an important social and health care problem because of its high incidence among patients who undergo surgery. Studies on the mechanical prophylaxis of thromboembolism after gynaecological pelvic surgery are few. The aim of our study was to evaluate the effect of mechanical thromboembolism prophylaxis after gynaecological pelvic surgery using a combination of graduated compression stockings (GCS) and intermittent pneumatic compression (IPC) or GCS alone.
METHODSThe study was performed on 108 patients who were randomly assigned to two groups. The first group received GCS before the operation and IPC during the operation (IPC + GCS group). The second group received GCS before the operation (GCS group). To analyze the effect of the preventive measures and the laboratory examination on the incidence of thrombosis and to compare the safety of these measures, the incidence of adverse reactions was assessed.
RESULTSThe morbidity associated with DVT was 4.8% (5/104) in the IPC + GCS group and 12.5% (14/112) in the GCS group. There were significant statistical differences between the two groups. There were no adverse effects in either group.
CONCLUSIONSThe therapeutic combination of GCS and IPC was more effective than GCS alone for thrombosis prevention in high-risk patients undergoing gynaecological pelvic surgery, and there were no adverse effects in either group.

PURPOSE: Venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism, is a serious and life-threatening complication in elderly (older than 65 years) patients undergoing hip fracture surgery (HFS). However, few have reported on the influences of VTE on postoperative rehabilitation in these patients. This study was performed to determine whether VTE affects clinical outcomes in patients who underwent HFS. MATERIALS AND METHODS: We retrospectively evaluated 330 HFSs in 325 consecutive patients, which were performed from January 2009 to June 2010. From chart review, we identified 15 patients with symptomatic VTE. We compared Geriatric depression scale, Modified Barthel index and Berg balance scale scores as well as 10 meter gait speed at discharge and hospital stay between a symptomatic VTE group and a non-VTE group. RESULTS: No significant difference in clinical outcomes at discharge between the two groups was found, although hospital stay was longer in patients with symptomatic VTE (p=0.012). CONCLUSION: East Asian patients have a low incidence of symptomatic VTE after HFS, and the clinical outcomes of patients with symptomatic VTE were similar to patients without VTE, although there was a longer rehabilitation period.

Permanent ischemic injury of the hand after radial artery cannulation is rare, but several cases of thromboembolism after the cannulation leading to amputation of affected limb or digits have been reported. A 48-yr-old man undergoing spine surgery showed normal modified Allen's test and had no preoperative vascular disease. We inserted 20-G radial artery catheter for the continuous monitoring of the blood flow and serial blood sampling. There was no specific event during the operation and the catheter was removed immediately after the operation. The signs and symptoms of the circulatory impairment of the radial artery developed four days after the operation and aggravated thereafter. Through the angiographic study, we found the total occlusion of the radial artery and some of its branches. After an emergent surgical exploration of the radial artery for removal of the thrombus and vein graft for the defect of the artery on the 8th postoperative day, the ischemic signs and symptoms disappeared and the radial pulse was restored.
