Inferior vena cava filters have been placed in patients for decades for protection against pulmonary embolism. The widespread use of filters has dramatically increased owing at least in part to the approval of retrievable vena cava filters. Retrievable filters have the potential to protect against pulmonary embolism and then be retrieved once no longer needed to avoid potential long-term complications. There are several retrievable vena cava filters available for use. This article discusses the different filter designs as well as the published data on these available filters. When selecting a filter for use, it is important to consider the potential short-term complications and the filters' window for retrieval. Understanding potential long-term complications is also critical, as these devices are approved for permanent placement and many filters are not retrieved. Finally, this article will address research into new designs that may be the future of vena cava filtration.

Catheter-related thrombosis (CRT) is a frequent and potentially serious complication associated with the widespread use of intravascular devices such as central venous catheters, including peripherally inserted central catheters and implantable port systems, pacemakers or implantable cardioverter-defibrillators. Although CRT management has been informed by guidelines extrapolated from lower extremity deep vein thrombosis (DVT), unique challenges remain due to the distinct anatomical, pathophysiological, and clinical characteristics of upper extremity DVT. Risk factors for CRT are multifactorial, encompassing patient-related characteristics such as cancer, prior venous thromboembolism, and infection, as well as catheter-specific factors like device type, lumens, and insertion site.

The three-vessel view (3VV) is a standardized transverse scanning plane used in fetal cardiac ultrasound screening to measure the absolute and relative diameters of the pulmonary artery (PA), ascending aorta (Ao), and superior vena cava, as required. The PA/Ao ratio is used to support the diagnosis of congenital heart disease (CHD). However, vascular diameters are measured manually by examiners, which causes intra- and interobserver variability in clinical practice.

A 28-year-old male presented to his physician with a chief complaint of fever and cough. Contrastenhanced computed tomography revealed a 17×16×8 cm heterogeneous tumor in the anterior mediastinum, as well as right heart and inferior vena cava compression due to the tumor. He was referred to our hospital for close examination and treatment.

Traditional mouse models for deep vein thrombosis (DVT), frequently utilized in research focused on cancer-associated thrombosis (CAT), reliably induce thrombus formation by obstructing blood flow (BF) in the inferior vena cava (IVC), which does not occur in humans. Therefore, to develop a new DVT model for CAT studies, we implanted an ameroid constrictor (AC), a hygroscopic casein C-shape device, around the IVC and aorta of immunocompromised mice. We evaluated the thrombus 3 and 8 days post-AC implantation and compared it with the traditional model 2 days post-vena cava ligation.

Objective: Radiographic findings to identify central venous catheter misplacement in the arteries, which can cause lethal complications, have not been fully evaluated, and its training is difficult because it is rare. The purpose of this study is to clarify radiographic findings for differentiating central venous and misplaced arterial lines using virtual chest radiographs and elucidate their usefulness in training radiologists.
Methods: This retrospective study included 150 patients (mean age, 67 [SD, ±12] years; 97 men) who underwent colon cancer surgery between January 2018 and December 2020.
