Abstract
Autoimmune diseases and thrombophilic disorders, notably antiphospholipid syndrome (APS) and protein S deficiency, present a formidable challenge in pregnancy, substantially increasing the risk of thromboembolic complications by up to 20%. Pulmonary thromboembolism (PTE), characterized by a significantly higher maternal mortality rate, is of particular concern. APS, defined by the presence of antiphospholipid antibodies, emerges as a pivotal risk factor for PTE during pregnancy, especially in women exhibiting triple negativity. Concurrently, protein S deficiency further amplifies vulnerability to thromboembolic events, establishing a high-risk scenario for pregnant individuals. In a case involving a 29-year-old pregnant woman with a history of generalized lupus erythematosus, triple-negative antiphospholipid syndrome, and protein S deficiency, sudden-onset dyspnea prompted thorough investigation. Despite her complex medical history, a multidisciplinary approach led to the accurate diagnosis and successful management of subsegmental pulmonary thromboembolism, ensuring the well-being of both mother and fetus. Effectively managing PTE during pregnancy demands a comprehensive, multidisciplinary approach involving collaboration among obstetricians, internists, rheumatologists, and hematologists. Accurate diagnosis, tailored anticoagulation strategies, and continuous monitoring stand as indispensable pillars for maternal and fetal well-being.

Abstract
Pulmonary thromboembolism (PTE) is a common complication in coronavirus disease 2019 (COVID-19) patients. Elevated D-dimer levels are observed even in the absence of PTE, reducing its discriminative ability as a screening test. It is unknown whether conventional D-dimer cut-off values, as used in the YEARS algorithm, apply to COVID-19 patients. This study aimed to determine the optimal D-dimer cut-off value to predict PTE in COVID-19 patients. All confirmed COVID-19 patients with a computed tomography pulmonary angiography (CTPA) performed ≤5 days after admission due to suspicion of PTE between March 2020 and February 2021, at Medisch Spectrum Twente, The Netherlands, were retrospectively analyzed. The association between PTE and D-dimer levels prior to CTPA, and other potential predictors, was analyzed using logistic regression analyses. The optimal cut-off value was identified using receiver operating characteristic (ROC) curve analyses. In 142 patients, PTE prevalence was 20.4%. The optimal cut-off value was 750 ng/mL (sensitivity 100%; specificity 19.5%; negative predictive value 100%; positive predictive value 24.2%). In total, 15 of 113 (13%) patients without PTE had a D-dimer level ≥500 and <750 ng/mL. In our population of patients hospitalized with COVID-19, a D-dimer level <750 ng/mL safely excluded PTE. Compared to the YEARS 500 ng/mL cut-off value, 13% fewer patients are in need of a CTPA, with similar sensitivity. Future research is required for external validation.

Abstract
Background A specific risk-stratification tool is needed to facilitate safe and cost-effective approaches to the prophylaxis of acute pulmonary thromboembolism (PTE) in lung cancer surgery patients. This study aimed to develop and validate a simple nomogram model for the prediction of PTE after lung cancer surgery using readily obtainable clinical characteristics. Methods A total of 14,427 consecutive adult patients who underwent lung cancer surgery between January 2015 and July 2018 in our institution were retrospectively reviewed. Included in the cohort were 136 patients who developed PTE and 544 non-PTE patients. The patients were randomly divided into the derivation group (70%, 95 PTE patients and 380 non-PTE patients) and the validation group (30%, 41 PTE patients and 164 non-PTE patients). A nomogram model was developed based on the results of multivariate logistic analysis in the derivation group. The cut-off values were defined using Youden's index. The prognostic accuracy was measured by area under the curve (AUC) values. Results In the derivation group, multivariate logistic analysis was carried out to evaluate the risk score. The risk assessment model contained five variables: age [95% confidence interval (CI): 1.008-1.083, P=0.016], body mass index (95% CI: 1.077-1.319, P=0.001), operation time (95% CI: 1.002-1.014, P=0.008), the serum level of cancer antigen 15-3 (CA15-3) before surgery (95% CI: 1.019-1.111, P=0.005), and the abnormal results of compression venous ultrasonography before surgery (95% CI: 2.819-18.838, P<0.001). All of them were independent risk factors of PTE. To simplify the risk assessment model, a nomogram model was established, which showed a good predictive performance in the derivation group (AUC 0.792, 95% CI: 0.734-0.853) and in the validation group (AUC 0.813, 95% CI: 0.737-0.890). Conclusions A high-performance nomogram was established on the risk factors for PTE in patients undergoing lung cancer surgery. The nomogram could be used to provide an individual risk assessment and guide prophylaxis decisions for patients. Further external validation of the model is needed in lung cancer surgery patients in other clinical centers.

Abstract
BACKGROUND AND AIMS The risk of pulmonary thromboembolism (PTE) in patients with exacerbated chronic obstructive pulmonary disease (e-COPD) is higher than in non-COPD states. This study aimed to evaluate the prevalence and the parameters that are critical for finding the incidence of PTE in patients with e-COPD. METHODS This cross-sectional study was performed on 68 consecutive patients with the e-COPD, referred to the Pulmonary Disease Department at the Shariati Hospital in Tehran between 2013 and 2014. In addition to collecting data on the history of disease and physical examination, arterial blood sampling, spirometry, electrocardiography and echocardiography were performed for all patients. All patients underwent the computed the tomography pulmonary angiography (CT-PA) as a method of choice for diagnosing PTE. RESULTS Out of 68 cases (7.4%), five were had CT angiography findings suggesting PTE. These patients were all male and had a higher mean age (79 vs. 65 years), lower mean systolic blood pressure (88.36 vs. 118.33 mmHg), and a higher mean heart rate (133.12 vs 90.33 beats/min), compared to e-COPD patients without PTE. Arterial blood gas analysis in patients with PTE demonstrated a lower HC03 (2.33 vs. 9.44 mEq/l) and PC02 (44.35 vs. 51.43 mmHg) levels. The mean LVEF was lower in patients with PTE (34.14 ±4.49% vs. 46.94 ± 8.27%). CONCLUSION The prevalence of PTE in our series of patients with e-COPD was 7.4%. According to the study results, male gender, advanced age, hypotension, tachycardia, and respiratory alkalosis are factors indicating possible PTE among patients with e-COPD.

Abstract
OBJECTIVE To determine the incidence of deep vein thrombosis (DVT)in patients undergoing spinal surgeries receiving prophylactic doses of Deltaparin in a single center in central Iran. METHOD This cross-sectional study was conducted in Shariatee hospital of Isfahan during a 12-month period. We included all the patients undergoing elective spinal surgeries in our center during the study period who received prophylactic dosages of subcutaneous Dalteparin (5000unit daily) thefirst postoperative day. Those with absolute contraindications of anticoagulation therapy were not included in the study. Patients were followed for 3 months clinically and the incidence of DVT was recorded. DVT was suspected clinically and was confirmed by color Doppler sonography. RESULTS Overall we included 120 patients with mean age of 44.8 ± 12.6years among whom there were 54 (45%) men and 66 (55%) women. Lumbar discectomy (32.9%)and laminectomy (20.2%)were the most common performed procedures. DVT was detected in 1 (0.83%) patient in postoperative period. None of the patients developed pulmonary embolism and none hemorrhagic adverse event was recorded. The patient was treated with therapeutic unfractionated heparin and was discharged with warfarin. CONCLUSION Our results shows the efficacy of LMWH (Dalteparin) in reducing the incidence of DVT to 0.83%. These results also show the safety of Dalteparin in spine surgery because of lack of bleeding complication.

Abstract
OBJECTIVES The purpose of this study was to determine whether dual-energy computed tomography (DECT) angiography could differentiate pulmonary thromboembolism (PTE) from pulmonary artery sarcoma (PAS). METHODS We prospectively enrolled 19 patients that had a filling defect in the main pulmonary artery on DECT. Six patients who had PAS and underwent DECT were retrospectively enrolled for comparison. Pathological results or follow-up CT after anticoagulation therapy were used to make the final diagnosis. Two investigators measured the following parameters at the filling defect in the main pulmonary artery: CT attenuation density [Hounsfield units (HU)], iodine-related HU (IHU) and iodine concentration (IC, mg/ml). RESULTS From a total of 25 patients (M:F = 10:15; mean age, 65 years old), 19 were categorised into the PTE group and six were categorised into the PAS group. The mean HU values were not significantly different between the PTE and PAS groups (45.5 ± 15.9 vs 47.1 ± 9.2 HU; P = 0.776). However, the mean IHU and IC values of the lesions were significantly different between the PTE and PAS groups (10.6 ± 7.2 vs 27.9 ± 9.1 HU; P = 0.004, and 0.61 ± 0.39 vs 1.49 ± 0.57; P = 0.001). CONCLUSIONS DECT angiography using a quantitative analytic methodology can be used to differentiate PTE and PAS. KEY POINTS • DECT can be useful for differentiation of PAS and PTE. • With quantitative analysis, DECT offers tissue characterisation by detecting lesion parameter increases. • The patients without predisposing factors for PTE can be candidates for DECT.

Abstract
PURPOSE It has been known for years that deep vein thrombi (DVT) start to develop during total joint arthroplasty. Previously, we reported effective prevention of venous stasis by transcutaneous electrical nerve stimulation (TENS). It is hypothesized that TENS might be a thromboprophylactic tool for the limb undergoing surgery. The purpose of this study is to clarify the clinical efficacy and safety of TENS in patients during total knee arthroplasty (TKA). METHODS Ninety patients undergoing primary TKA were involved and randomly allocated to the TENS or control group. In the TENS group, electrical stimulation of the common fibular nerve, which produced a brisk dorsiflexion of the ankle, was performed for the operated leg during surgery. In the control group, no electrical stimulation was applied. Serum D-dimer and soluble fibrin monomer complex (SFMC) levels were measured before surgery, immediately after surgery, and post-operative day (POD) 1. Ultrasonography was performed on POD 1. RESULTS Immediately after surgery, D-dimer and SFMC levels of each group were significantly lower in the TENS group compared with control (p < 0.05). The incidence of DVT was 11 % (five cases) in the TENS group while 31 % (14 cases) in control (p = 0.02). There were no adverse effects related to TENS. CONCLUSIONS TENS during TKA showed significant effects on preventing DVT. Sustaining muscle pump activation during surgery prevented not only venous stasis, but also hypercoagulability of blood. Intraoperative TENS is a safe and novel strategy against early post-operative thromboembolism, which is difficult to be completed through existing prophylaxis after total joint arthroplasty. LEVEL OF EVIDENCE Randomized controlled trial, Level I.
