Disease relevance of Venae Cavae

• The aim of this study was to determine the temporal changes and the location of VEGF and bFGF expression in a rat model of venous thrombus resolution.Design and Methods: Thrombi were induced in the inferior venae cavae of rats by creating a stenosis to reduce blood flow by 80% to 90% [1].

High impact information on Venae Cavae

• There was production of plasma lipid choline by the upper- and lower-body regions drained by the venae cavae [2].
• Significant differences were observed in vena cava with diameters greater than 22 mm where capture rate was 76% as opposed to 86% in venae cavae less than 22 mm (p = 0.01) [3].
• The venae cavae were ligated, and the right ventricle was cannulated through the pulmonic valve to collect coronary sinus effluent for measurement of coronary outflow O2 tension, adenosine, and inosine [4].
• Fifteen homemade retrievable coils with thermal shape memory (TSM) nitinol wire cores were acutely deployed in the abdominal aortae or inferior venae cavae of four pigs (part II) [5].
• Blood samples for endotoxin measurement were drawn simultaneously from the superior and inferior venae cavae before heparin administration, 5 and 50 minutes after the onset of bypass, 5 minutes after aortic declamping, at the end of bypass, and 1, 2, and 20 hours after the end of cardiopulmonary bypass [6].

Anatomical context of Venae Cavae

• However, the presence of ANP-containing specific granules in the venae cavae and the pulmonary veins may suggest participation of these veins in the production and secretion of the hormone [7].
• Endothelial cells lining guinea pig inferior venae cavae change shape when exposed to histamine, bradykinin, A23187 or platelet-activating factor (PAF) in vitro [8].
• In order to investigate superoxide production by pulmonary macrophages in the rat, a route was created by ligating both the inferior and superior venae cavae and resecting the aorta after cannulation through the inferior vena cava into the right atrium of the heart [9].

Associations of Venae Cavae with chemical compounds

• Small latex balloons were introduced into the venae cavae of rats in whom aortocaval fistulae had been surgically created 3 weeks earlier [10].
• After median sternotomy, intravenous heparin was administered (3 mg. per kilogram) before the aorta and the superior and inferior venae cavae were cannulated for bypass [11].
• The results of this investigation show that the vagus has a powerful action on the venae cavae resembling that on the atria and mediated by acetylcholine [12].
• In Exp. 1, six gilts (BW 53 kg) with catheters in their venae cavae were used in a 5x5+1 Latin square design to determine the amount of infused urea needed to mimic the plasma urea concentration of pigs fed a 25% CP diet [13].
• The blood supply to the cranial venae cavae on both sides and to the heart was studied macroscopically in 40 adult laboratory shrews (Suncus murinus) of both sexes injected either with Neoprene latex into the abdominal aorta (25 animals) or with Mercox into the left ventricle (15 animals) [14].

Gene context of Venae Cavae

• The location and orientation of the valves, the atrial chambers, venae cavae, and pulmonary hili were found to be the most critical information [15].
• To assess the effect of vasopressin (VP) on systemic capacity (SC), blood was drained from the venae cavae to an oxygenator and returned to the aorta at a constant rate so that changes in SC could be measured as the inverse of changes in oxygenator volume in 17 anesthetized pigs [16].

Analytical, diagnostic and therapeutic context of Venae Cavae

• Two cases of the double inferior venae cavae (IVC) were found during the student dissection practice in 1997 in Gifu University School of Medicine. On the first case (70-year-old male), the calibers of the right and left IVC were 15 mm and 13 mm, respectively [17].
• It shows that locating the inferior vena cava between the superior venae cavae may lead to better-balanced lung perfusion [18].
