Purpose To determine with spiral computed tomography (CT) the incidence and caval location of left renal vein (LRV) variants that may affect inferior vena cava (IVC) filter placement, spermatic vein embolization, and adrenal or renal venous sampling. Materials and Methods Contrast material-enhanced ...
Thereafter, drainage is variable, depending on the location. The upper esophagus drains to the superior vena cava, the midesophagus drains to the azygous veins, and the distal esophagus drains to the portal vein. Portal hypertension leads to dilation of the deep intrinsic veins, eventually ...

This cohort study determines if inferior vena cava filter insertion in trauma patients affects overall mortality.
4 Placing the device in an unsuitable location, device failure, and an enlarged vena cava (diameter > 28 mm) are risks of embolization.3 The U.S. Food and Drug Administration recommends that physicians are responsible for removing the filter when no longer needed in a timely...
(B) Venogram showing an inferior vena cava filter (IVCF) placed below the renal arteries. The filter is then inserted according to the instructions for use. Confirmation of complete IVCF deployment, placement in the intended location, and correct orientation are important. Operator errors include ...
