Intracardiac baffle with single patch technique was done in 9 patients in whom right superior pulmonary vein was draining at the junction of right atrium and SVC.
While warden procedure was done in one patient in which right superior pulmonary vein was draining into the upper part of SVC.
Superior vena cava (SVC) syndrome occurs due to mechanical obstruction of blood flow to the right atrium of the heart through SVC. This occurs mostly due to compression or invasion of SVC by mediastinal masses (e.g.
Multiple marginally enlarged lymph nodes were noted at pretracheal, right paratracheal, subcarinal region and at aortopulmonary window; but once again, the aetiology of SVC syndrome remained undiagnosed as no lymph node or mass was found to compress SVC. An additional small well-defined heterogeneously enhancing nodule (26x33 mm) was detected in right lobe of thyroid.
The voltage profile and stability have improved when the system has unturned SVC, compared to the system without SVC.
Analysis with the presence of FACTS devices will be done in three ways, Analysis in the presence of SVC, Analysis in the presence of TCSC and Analysis in the presence of TCSC and SVC.
In this state, the constant sizes will be considered for the 2 MVAr SVC. These sizes will be changed between 0 to 100 MVAr step by step.
In this paper the lead-lag controller is proposed using the generator speed fluctuation (Do), as a modulated signal to SVC.
The SVC is modeled by a suceptance as used for power flow calculations, but varying within limits depending on the control performed by the voltage regulator of the a SVC.
"We are very pleased to join the Cognizant family," said Frank Leal, co-founder and managing principal, SVC.
"The combination of our market-leading consulting capability in the entertainment segment and Cognizant's strengths as a top global services player will allow us to deliver superior services to our collective clients by providing them with a broader range of services.
This finding led us to suspect the absence of hepatic segment of the IVC and venous drainage of lower extremity is maintained via persistent left SVC.
Further injection from the right antebrachial vein showed the right atrial filling from SVC (Fig.
"Customers choose an SVC contract to reduce and control maintenance costs and reduce their risk," said David Augustine, director of Thermo King SVC.
"Because of the volume of units requiring support, we believed placing a service manager on-site at Central Refrigerated was in the best interest of both parties."
