The angiographic patterns of the primary retroperitoneal tumors. The role of the lumbar arteries.

Abstract The lumbar and inferior intercostal arterial systems provide a major arterial supply of the retroperitoneal area, and abnormalities in their configuration, position, distribution, and size may indicate whether a mass is retroor intraperitoneal. In some instances, the histological nature of the mass may be predicted by the characteristics of its blood supply. Aortography with subsequent selective angiography to evaluate the feeding vessels and their branches is of value in the diagnosis of retroperitoneal masses.

Roentgen aspects of umbilical vascular catheterization in the newborn. The problem of catheter placement.

Radiographic examination represents the only method for the exact localization of intravascular catheters. There has been, however, no review of the technic of umbilical arterial and venous catheterization in newborn infants in the radiographic literature. Moreover, in the evaluation of films of infants with the respiratory distress syndrome, cardiac disorders, or abdominal abnormalities, the radiologist tends to concentrate on anatomical and physiological pathology and pays little attention to the localization or significance of catheters positioned below the diaphragm. Indeed, he may fail to consider the potential complications of the use of such catheters. Catheterization of the umbilical vein was utilized by Diamond et al. (1) in 1946 for the purpose of exchange transfusion in infants with erythroblastosis fetalis. Later, catheterization of the vein, as well as of the umbilical artery, was used for angiocardiography (3) and now is employed quite routinely for withdrawal of blood for gas analysis and f...

Perirenal Hematoma in Association with Renal Infarction in Sickle-Cell Trait!

Massive renal infarction with perirenal hematoma formation occurring in sickle-cell trait has not been previously reported. Various renal complications in patients with sickle-cell trait have been described by Harrow (5), Kay (6), and Vix (13), but no cases of extensive renal infarction were included. The present report describes infarction of the kidney and demonstrates the radiographic features of perirenal hematoma in the sickle-cell trait. The association of sickle-cell hemoglobinopathy and hematuria was first reported by Goodwin in 1950. Since then hematuria and renal papillary necrosis have been described in hemoglobin SA, SC, and SD disease (5, 6, 13). Gunnells and Grim (4), reporting hematuria in AD hemoglobinopathy, emphasized that hemoglobinopathies must be considered in cases of “essential” or “unexplained” hematuria. Case Report A 33-year-old Negro laborer was hospitalized with right upper quadrant abdominal pain of twelve hours duration. During the preceding two years the patient had experien...
