A 60s woman was diagnosed with cecal cancer with multiple liver metastases(final pathology was T4aN1M1[H1])and underwent ileocecal resection and D3 dissection. She did not wish for postoperative chemotherapy and surgical treatment of liver metastases. One and a half years after surgery, she developed extremity edema of lower legs and hypoalbuminemia, and she gained 20 kg. Contrast-enhanced CT showed stenosis of the inferior vena cava due to liver metastases, which was markedly improved the symptoms by placement of an inferior vena cava stent. Inferior vena cava stent placement is a minimally invasive treatment and can be an option as it can be expected to improve quality of life in some cases.

Ultrasonographic assessment of the diameters of various veins and their indices are among the most applied diagnostic tools for evaluating fluid responsiveness in clinical practice. Despite their widespread use, there is no definitive answer on which is preferable. Our study aimed to investigate the diagnostic accuracy of different venous diameters and their indices to assess fluid responsiveness.

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: Renal cell carcinoma tends to invade venous structures, frequently extending beyond the inferior vena cava and into the heart itself, such as into the right atrium or right ventricle. Resection of tumor burden, particularly tumor thrombus, often requires cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA), which is not feasible for all patients.
Methods: Described in this study is a novel, minimally invasive endovascular approach involving endovascular thrombectomy as a viable approach in these select patients.

The purpose of this article is to overview the clinical significance of left supraclavicular adenopathy and review the etiology of inferior vena cava (IVC) thrombosis, starting from a presentation of a rare case of renal cell carcinoma (RCCs) with Xp11.2 translocation involving TFE3 gene fusion. This article also aims to review the literature to understand the characteristics of this rare type of renal tumor.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.
Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.
