The superior vena cava (SVC) is a main source of non-pulmonary vein (PV) ectopies that initiate atrial fibrillation (AF). While there is some local variability in the use of inferior vena cava filters and there has been some evolution in the indications for filter placement over time, inferior vena cava filters remain. In 2003, the first retrievable inferior vena cava filter (rIVCF) was approved for patients at risk for VTE with short-term contraindication to anticoagulation. NEXT Methods: This is a prospective, cross-sectional study which included adult multi-trauma patients (>18 years) who were admitted to the emergency department (ED) and underwent a thoraco-abdominal CT from 2017 through 2018.

The inferior vena cava runs parallel to the abdominal aorta on the right side. Your superior vena cava, your second biggest vein, brings oxygen-poor blood from your upper body to your heart. The superior vena cava is a thin-walled, low pressure vessel which makes it vulnerable to compression. We present a case for which the . Hooks were added to the filters to decrease the incidence of filter migration, but this has shown to increase inferior vena cava perforation rates significantly. Its location is in the superior and middle mediastina. CT enables to determine tumor size, identify relations with adjacent organs, and search for metastases [4]. Right atrium 3. The case we present in this paper shows typical findings of this entity (Fig. Organisms 1. Hypotension is a common side effect of general anesthesia induction, and when severe, it is related to adverse outcomes. There is a syndrome of the upper and inferior vena cava due to a circulatory disorder in the superior vena cava. 11 ): an interruption of the infrarenal inferior vena cava and its continuation as the azygos vein. It collects blood from veins serving the tissues inferior to the heart and returns this blood to the right atrium of the heart. In older fetuses the attached border of the diaphragm splits into several layers at its junction with the inferior vena cava. The IVC starts in the lower back where the right and left common iliac veins (two major leg veins) have joined together. Inferior Vena Cava (IVC) The IVC's job is to drain all the blood from the lower half of the body including the feet, legs, thighs, pelvis, and abdomen. A doctor uses a thin catheter that is inserted into your neck or groin to put the filter in place . Esenther G.
