Decompression of superior vena cava during bidirectional Glenn shunt: A simple but risky technique

Systemic-to-pulmonary venous shunt in superior vena cava obstruction.

Superior vena cava obstruction is associated with multiple venous collaterals. There is an unusual pathway involving pulmonary venous collaterals in which systemic veins drain directly into the left heart, resulting in a right-to-left shunt. We report here a rare case of systemic to pulmonary venous shunt on both hemithoraces in superior vena cava obstruction associated with Budd-Chiari syndrom...

Development of pulmonary arteriovenous shunt after superior vena cava-right pulmonary artery (Glenn) anastomosis. Report of four cases.

Four patients with cyanotic congenital heart disease who had previously undergone superior vena cava-right pulmonary artery (Glenn) anastomosis developed pulmonary arteriovenous malformations that resulted in significant intrapulmonary right-to-left shunting. This abnormality was documented by selective angiography, oximetry, and contrast echocardiogrphy. It may be a major cause of late clinica...

Is interrupted inferior vena cava a risk factor in cases of bilateral bidirectional Glenn?

INTRODUCTION Bilateral superior vena cava-to-pulmonary artery anastomoses are technically challenging. Bilateral superior vena cavae (SVCs) have been thought to be a risk factor for poor outcome in children needing single-ventricle palliation. METHODS The files of forty children who underwent bilateral cavopulmonary anastomoses (CPAs) were reviewed. RESULTS Forty patients (31 male, 9 female...

Askin Tumor Presenting as Superior Vena Cava Syndrome

[Bidirectional Glenn shunt without cardiopulmonary bypass].

From April 2002 to March 2005, 18 patients having undergone bidirectional Glenn shunt (BDG) without cardiopulmonary bypass (CPB) [off-pump BDG] were retrospectively reviewed. During BDG anastomosis, a temporary bypass was established between superior vena cava (15) or innominate vein (3) and main pulmonary artery (16) or right atrium (2). Hemodynamics and oxygenation were maintained well throug...
