We present a 43-year-old patient with paroxysmal supraventricular tachycardia. In the process of catheter ablation, we found interruption of the inferior vena cava with azygos continuation with incomplete situs inversus. In this patient, we adopted the lower approach via the anomalous inferior vena cava and azygos continuation to achieve stability of radiofrequency catheter for right posterosep...

The eustachian valve directs oxygen-rich blood from the inferior vena cava toward the foramen ovale and away from the tricuspid valve during fetal development. Ordinarily, it does not prevent reflux of right atrial blood back into the inferior vena cava because it does not function as a true valve. Here we describe an unusual adult patient with severe tricuspid valve regurgitation in whom the e...

105 Rev Esp Med Nucl. 2007;26(2):105-6 FIG. 1.—Unenhanced-multiplanar CT reconstruction images. 1A, horseshoe kidneys, the isthmus is lying anterior to the inferior vena cava and aorta; a Greenfield’s intracaval filter is seen in the inferior vena cava and an atherosclerotic plaque in the abdominal aorta. B, C, and D; both ureters were seen along their course until the ureterovesical junction. A C

Nutcracker syndrome is a condition where there is compression of the left renal vein between the aorta and the superior mesenteric artery causing symptoms. Here, we describe the case of a female patient who had symptoms secondary to the compression of a left inferior vena cava between the aorta and the superior mesenteric artery causing a nutcracker syndrome. We will review the etiology, embryo...
