Radiological evidence of anatomical variation of the inferior vena cava: Report of two cases

摘要: The inferior vena cava (IVC) is a retroperitoneal key structure whose location and integrity must be checked in every scan. A number of studies are reported the literature concerning congenital variations cava. Anatomical this main venous trunk relatively infrequent clinical findings during surgery or diagnostic procedures patients without symptoms such as an aberrant drainage abdominal pain. Among other imaging techniques, computerized tomography non-invasive, effective technique for diagnosing diseases space and, particularly, detecting anomalies vessels, aorta IVC, asymptomatic patients. We present two cases IVC variation incidental finding studied by means CT scan gradation kidney carcinoma pancreatic cancer respectively. Two different configurations system (agenesis with hypertrophy azygos vein double respectively) were found our cases. embryological development discussed, bearing mind that knowledge important order to avoid major surgical complications.
