Anatomical context of Vena Cava, Superior

• The connecting site was the superior vena cava (SVC) in 39 veins (59.1%), right atrial-SVC junction in 6 (9.1%), right atrium in 8 (12.1%), inferior vena cava in 1 (1.5%) and the coronary sinus in 2 (3.0%) [15].
• The superior vena cava (SVC) and thoracic inferior vena cava (IVC) were replaced in 46 dogs with autologous vein, knitted Dacron, glutaraldehyde-fixed porcine pericardium, unsupported polytetrafluorethylene (PTFE), and externally stented PTFE [16].
• Single cardiomyocytes, isolated from the canine pulmonary veins (PV) and superior vena cava (SVC) using digestive enzymes, were examined by immunoconfocal microscopy using antisera against connexin43 (Cx43), Cx40, and other cell markers [17].
• The brachiocephalic, azygos, pulmonary and splenic veins and the superior vena cava and the supradiaphragmatic portion (segment A) and the infrarenal portion (segment D) of the inferior vena cava responded little to clonidine [18].
• Collateral development was secondary to a long segment idiopathic venous occlusion involving bilateral subclavian and brachiocephalic veins as well as vena cava superior [19].

Associations of Vena Cava, Superior with chemical compounds

• Bipolar electrodes were used to record from the atria and thoracic veins, including the vein of Marshall, four PVs, and the superior vena cava [20].
• OBJECTIVES: To examine the hemodynamic effects of milrinone given prophylactically to very preterm infants at high risk of low superior vena cava (SVC) flow and to investigate the preliminary efficacy and safety of an optimal dose [21].
• Doses of 15-40 mug/kg injected into the superior vena cava or the right atrium produced depression of the reflex responses in extensor and flexor alpha motoneurons after latent periods of 1-3 sec, while gamma activity was initially accelerated [22].
• Infants (n = 42) with low superior vena cava (SVC) flow (<41 mL/kg/min) in the first 12 hours were randomly assigned to receive 10 mL/kg normal saline solution, followed by 10 microg/kg/minute of dobutamine or dopamine [23].
• In the collateral system, the three agonists exhibited approximately 3-fold differences in their relative activities when administered by rapid injection into the superior vena cava, with PGD2 greater than PGF2 alpha greater than histamine [24].

Gene context of Vena Cava, Superior

• PURPOSE: To identify prognostic or treatment factors influencing the response of superior vena cava obstruction (SVCO), time to SVCO recurrence, and overall survival of SCLC patients with SVCO at presentation; and to assess the role of retreatment in patients with SVCO at recurrent or persistent disease [25].
• Recurrence of thymoma presenting as a superior vena cava syndrome [26].
