Interposition with a vascular prosthesis or patch closure using autologous pericardium has been applied for superior vena cava (SVC) reconstruction during surgery for thoracic malignancies such as thymic epithelial tumors or lymphadenopathy that invade the SVC. We herein report a novel and simple method for repair of the SVC using a left brachiocephalic vein flap. This procedure is useful to re...

OBJECTIVES To document the incidence, timing, degree, and associations of systemic hypoperfusion in the preterm infant and to explore the temporal relation between low systemic blood flow and the development of intraventricular haemorrhage (IVH). STUDY DESIGN 126 babies born before 30 weeks' gestation (mean 27 weeks, mean body weight 991 g) were studied with Doppler echocardiography and cereb...

Introduction. For patients with terminal heart failure, heart transplantation (HTX) has become an established therapy. Before transplantation there are many repeated measurements with a pulmonary artery catheter (PAC) via the superior vena cava (SVC) necessary. After transplantation, endomyocardial biopsy (EMB) is recommended for routine surveillance of heart transplant rejection again through ...

This paper presents a laboratory model for a shunt static var compensator (SVC). Such shunt static var compensator (SVC) is useful in the control of power distribution feeders. The type of the SVC considered in this investigation is the famous thyristor-controlled reactor (TCR) configuration. LABVIEW software has been used as a practical platform to control the operation of the SVC thyristors. ...

DESIGN Observational study. SETTING Tertiary University Hospital. PARTICIPANTS/PATIENTS Patients, aged 6 days to 19 years, who underwent contrast enhancement computerized tomography imaging of the thorax (CT-thorax). MAIN OUTCOME MEASURES We measured three lengths consisting of length A in axial plane at the level of the lower border of the 6th C-spine from the skin to RIJV at its mid lum...

Clinical, hemodynamic, and angiocardiographic findings on eight long-term (more than 3 years) survivors of anastomosis of the superior vena cava (SVC) to the right pulmonary artery (RPA) are described. All patients had severe cyanotic congenital heart disease with decreased pulmonary blood flow. Postoperative cardiac catheterization and angiocardiography defined the physiology of the shunt. SVC...

This paper addresses the efficient adaptation of encrypted scalable video content (H.264/SVC). RTP-based in-network adaptation schemes on a media aware network element (MANE) in an IPTV and VoD scenario are considered. Two basic alternatives to implement encryption and adaptation of H.264/SVC content are investigated: (i) full, format-independent encryption making use of Secure RTP (SRTP); (ii)...

The initiation of focal atrial tachycardia (AT) from the superior vena cava (SVC) remains unclear. In 3 patients (2 females, 1 male; aged 57, 66 and 50 years, respectively) with focal AT arising from different parts of the SVC, the AT occurred spontaneously, rather than being induced by electrical stimulation. The cycle length of the tachycardia was highly variable, ranging between 190 and 300 ...

The scalable extension to the H.264/AVC has been established as a scalable video coding (SVC) standard, and JPEG2000 is a state of the act still image coding standard. The most distinctive difference between SVC and JPEG2000 is, in terms of spatialfrequency transformation, that SVC is based on the Discrete Cosine Transform (DCT) and JPEG2000 is based on Discrete Wavelet Transform (DWT). JPEG200...
