Background: Pulmonary embolism (PE) from deep venous thrombosis (DVT) can be a fatal postoperative complication. Preventive measures for venous thromboembolism (VTE) was evaluated in this hospital.
Materials And Methods: Preoperative DVT screening following surgery under general anesthesia in 2009-2016 was examined, and then, 217 patients diagnosed with DVT by preoperative leg-ultrasound (US) between 2014 and 2016 were retrospectively analyzed.
Results: There were 24,826 operations under general anesthesia in the study period. Preoperative leg-US was performed in 5345 (21.5%) patients, and 648 (12.1% of patients, 2.6% of total operations) were diagnosed with DVT. In 2014-2016, 217 patients, which is 11.7% of patients undergoing leg-US, were diagnosed with DVT. DVT was found in the proximal veins (upper popliteal vein) in 86 (39.6%) patients. A total of 143 (62%) patients were considered to have organized thrombi, no patient developed pulmonary embolism, and 133 (58%) patients were discharged without follow-up examination for DVT. Ninety-six patients were evaluated for changes on leg-US, with no difference in the results with and without anticoagulant use. On multivariate logistic regression analysis, anticoagulants appeared effective for non-organized thrombi, higher D-dimer levels (≥10 μg/mL), or orthopedic surgery.
Conclusion: Preoperative screening for DVT did not appear useful, and treatment of asymptomatic DVT was not always necessary.

"May-Thurner syndrome as an underlying cause of unilateral left-sided deep vein thrombosis in a young healthy female: A case report".
Radiol Case Rep
March 2025
Department of Radiology, Rafidia Surgical Hospital, Nablus, Palestine.
May-Thurner syndrome (MTS), iliac vein compression syndrome, also called Cockett syndrome, is a vascular disease caused by the compression of the left common iliac vein (LCIV) by the right common iliac artery (RCIA) against the lumbar vertebrae. This anatomical defect can lead to venous stasis especially in the left lower limb, and this increases the risk of deep venous thrombosis (DVT). Because routine screening is not standard practice, MTS frequently remains asymptomatic, and its prevalence is probably underestimated.

Deep vein thrombosis (DVT) in patients undergoing endoscopic endonasal surgery remains underexplored, despite its potential impact on postoperative recovery. This study aimed to develop and validate a predictive nomogram for assessing the risk of lower-limb DVT in such patients without chemoprophylaxis. A retrospective analysis was conducted on 935 patients with postoperative lower-limb vein ultrasonography.

It has been documented that D-dimer levels have potential utility as a measure of tumor activity in diffuse large B-cell lymphoma (DLBCL), however whether it can be used as a predictive marker of treatment outcome has not been established. This study means to retrospectively evaluate the role of D-dimer in prediction of treatment efficacy in patients with DLBCL. 151 patients with newly diagnosed DLBCL were enrolled.

Objective: To investigate coagulation disorders and thrombotic complications in the early stage after burn, and to evaluate the predictive reliability of D-dimer for deep vein thrombosis (DVT) diagnosis in major burn patients.
Methods: This retrospective study was performed in the Department of Burns, Southwest Hospital, and included 288 adult major burn patients (≥40 % TBSA) without prophylactic anticoagulant therapy. All patients received routine screening assays of coagulation indicators and Doppler ultrasound scan (DUS) during the 28 days post-burn regardless of the clinical symptoms of DVT.

School of Medicine; College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia.
Background: Thromboembolic events are a common cause of morbidity and mortality in patients with cancer. While direct-acting oral anticoagulants (DOACs) have been established as the preferred agents of anticoagulation in most patients with cancer, data in resource-limited settings is limited.
Aims: The study aims to assess the comparative efficacy and safety of warfarin and rivaroxaban for cancer-associated thrombosis (CAT) in a resource-limited setting.
