Variations in the Number and Drainage Levels of Retroaortic Left Renal Veins

Objective: To determine the prevalence of inferior vena cava (IVC) anomalies in Thai patients who underwent contrast-enhanced computed tomography (CT) of the abdomen. Materials and Methods: Two radiologists retrospectively and independently reviewed the contrast-enhanced abdominal CT examinations in 1,429 Thai patients between August 1, 2018 and January 25, 2019 who met the inclusion criteria. Patients were included, if (a) their CT showed well visualized IVC, renal veins, and right ureter that were not obliterated by tumor, cyst, fluid collection, or intraperitoneal free fluid, (b) they had not undergone previous abdominal surgery that altered anatomical configuration of the IVC, renal veins, and right ureter. The presence of all IVC anomalies were recorded. Results: Among the 1,429 studied patients, 678 were male (47.4%) and 751 were female (52.6%). The prevalence of IVC anomalies was 3.5%. Five types of IVC anomalies were presented. The most common was circumaortic left renal vein in 24 patients or 48.0% of all IVC anomalies and 1.7% of the study population, followed by retroaortic left renal vein in 15 patients or 30.0 % of all IVC anomalies and 1.0% of the study population. Other IVC anomalies included double IVC, left IVC, and retrocaval ureter at 0.5%, 0.2%, and 0.1% of the study population, respectively. Conclusion: The prevalence of IVC anomalies in the present study differed from the previous studies conducted in other countries, which may be attributable to differences in race and ethnicity. Awareness of these anomalies is essential when evaluating routine CT examinations in asymptomatic patients. Their presence should be carefully noted in radiology reports to avoid anomaly-related complications.

ABSTRACT Serum somatomedin (SM) activity, measured as sulphation factor on chick embryo cartilage, and growth hormone (GH) levels were measured in peripheral, hepatic and renal veins of 23 patients with alcoholic cirrhosis. SM activity (mean ± sem) was 0.65 ± 0.05 U/ml in peripheral vein, 0.59 ± 0.04 U/ml in hepatic vein, and 0.74 ± 0.07 U/ml in renal vein. Mean GH levels were respectively 2.8, 2.5 and 3.1 ng/ml. Compared to peripheral vein, SM increase in renal vein was 19% (P < 0.05). Serum SM activity was significantly lower in 13 patients with alcoholic hepatitis associated with cirrhosis than in other 10 patients (P < 0.02 in hepatic blood and P < 0.05 in peripheral blood). The decrease of SM activity seems related to cytolysis and hepato-cellular insufficiency. At last, in patients with alcoholic hepatitis, SM activity was lower in the hepatic vein than in the peripheral vein (P < 0.05). The cause of this difference remains under discussion, no SM inhibitors being found in the serum samples used in this study.

Ovarian Vein Thrombosis

A clinical case of thrombosis of the right ovarian vein in the postpartum period - an extremely rare pathology in which acute appendicitis is often suspected due to the identity of the symptoms of the diseases. Performed laparoscopy, during which a large fragment of a thrombosed vein was excised. Conclusion. Extensive right ovarian vein thrombosis with a normal hemostasiogram could not only not be resolved by anticoagulants, but also potentially spread to the renal veins and inferior vena cava, increasing the risk of pulmonary embolism. Key words: vein dissection, laparoscopy, postpartum period, ovarian vein thrombosis

Arteries And Veins

AbstractThe aim of this study was to describe origin, localisation and variations of renal arteries and veins in the rabbit. The study was carried out on 40 adult European rabbits. We prepared corrosion casts of the rabbit arterial and venous system. Spofacryl was used as the casting medium. In 75% of cases the origin of arteriae renales was located at the level of the third lumbar vertebra and in remaining 25% of cases arteria renalis dextra branched off at the level of the second lumbar vertebra. In 10% of cases we observed that the number of arteria renalis sinistra was doubled. We recorded also in one case the presence of arteria renalis accessoria for ren dexter. In 10% of cases we observed that the number of vena renalis sinistra was doubled. In 5% of cases two venae renales sinistrae arose from the kidney and subsequently, about 1 cm from opening to vena cava caudalis, they united to form a single vein. In 5% of cases two venae renales sinistrae arose from the kidney and subsequently, approximately 1 cm away from hilus renalis, they united. The obtained variations of the number of renal arteries were partially homologous to the human, but variations of renal veins were localized on the other side as in human.
