Migration of an inferior vena cava (IVC) filter to the heart after placement is an extremely rare complication. The case of a 42-year-old man who presented with ventricular arrhythmia and tricuspid valve regurgitation, and underwent open heart surgery to extract an IVC filter from the right ventricle 12 days after infrarenal IVC filter placement, is reported.

Background: Isolated subsegmental pulmonary embolism (issPE) is a commonly encountered diagnosis. Although the International Classification of Diseases (ICD)-10 codes are used for research, their validity for identifying issPE is unknown. Moreover, issPE diagnosis is challenging, and the findings from radiology reports may conflict with those from expert radiologists.

Inferior vena cava (IVC) filters are vital in preventing pulmonary embolism (PE) by trapping large blood clots, especially in patients unsuitable for anticoagulation. In this study, the accuracy of two common simplifying assumptions in numerical studies of IVC filters-the rigid wall assumption and the laminar flow model-is examined, contrasting them with more realistic hyperelastic wall and turbulent flow models. Using fluid-structure interaction (FSI) and computational fluid dynamics (CFD) techniques, the investigation focuses on three hemodynamic parameters: time-averaged wall shear stress (TAWSS), oscillatory shear index (OSI), and relative residence time (RRT).

Background: Pregnancy-associated venous thromboembolism (PA-VTE) seriously threatens maternal health. We aimed to investigate the clinical characteristics, risk factors, treatments, and pregnancy outcomes to better prevent and treat PA-VTE.
Methods: PA-VTE patients were selected from 171,898 women who were registered in the Department of Obstetrics of Fujian Maternity and Child Health Hospital from January 2014 to August 2023 and delivered to calculate the incidence.

A 50-year-old female presented with a 10-day history of progressive swelling and pain in the left lower extremity, ultimately diagnosed with deep vein thrombosis (DVT) and May-Thurner Syndrome (MTS). Initial ultrasound indicated thrombosis involving the left external iliac, femoral, and popliteal veins, among others. Blood tests revealed normocytic anemia, but thrombophilia screening and other blood markers were normal.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.
