2025年1月24日 · Inferior vena cava filter, or just IVC filter, is an endovascular device that is typically placed in the infrarenal inferior vena cava (IVC) to prevent pulmonary embolism in selected patients. This procedure is most often performed by interventional radiologists under fluoroscopic guidance.

Positioning the tip of a central venous catheter (CVC) within the superior vena cava (SVC) at or just above the level of the carina is generally considered acceptable for most short-term uses, such as fluid administration or monitoring of central venous pressure. Ideally the distal end of a CVC should be orientated vertically within the SVC.

2024年6月12日 · The inferior vena cava (IVC) (plural: inferior venae cavae) is one of the great vessels that drains venous blood from the lower limbs, pelvis and abdomen into the right atrium of the heart. The inferior vena cava is formed by the confluence of the two common iliac veins at the L5 vertebral level.

The most common CXR-detectable complications are pneumothorax, malposition (looping, inferior vena cava (IVC) positioning of the tip, wrong thoracic vein positioning), or, less often, vascular perforation, with the catheter located inside the thorax (Figure 3, …

2013年2月18日 · The chest x-ray is the most frequently requested radiologic examination. In fact every radiologst should be an expert in chest film reading. The interpretation of a chest film requires the understanding of basic principles. In this article we will focus on: Normal anatomy and variants. Systematic approach to the chest film using an inside-out ...

Widened mediastinum is defined as mediastinum with a measured width greater than 6 cm on an upright posterior–anterior chest radiograph (CXR) or 8 cm on supine anterior–posterior chest film [1]. Multiple etiologies can be identified including traumatic and nontraumatic causes; most of them require an urgent management to improve patients' survival.

2018年12月1日 · Inplantable cardioverter-defibrillators (ICD's) that are capable of defibrillating the heart to prevent cardiac arrest. Pacemakers can have leads, that pace: Right atrium - tip of lead is located in atrial appendage. Right ventrical - tip in apex.

2019年7月30日 · Inferior vena cava (IVC) filters are commonly used in patients at risk for life-threatening pulmonary embolism. Since the Mobin-Uddin filter was introduced in 1967, numerous other IVC filters have been developed.

CXR is often the initial imaging screening test to identify and evaluate such devices, and thus plays a crucial role. It can provide easy confirmation of optimal device placement and help in early detection of potentially grave complications related to abnormal placement before these are manifested clinically.

2013年11月5日 · In this review we will discuss the normal and abnormal position of tubes and lines on a neonatal chest x-ray. Umbilical artery catheterization provides direct access to the arterial system and allows accurate measurement of arterial blood pressure, blood sampling and intravascular access for fluids and medications.
