Abstract:
Bidirectional cavopulmonary anastomosis can be made either with conventional cardiopulmonary bypass, or with temporary veno-atrial shunt or without shunt. The purpose of the present report is the control of central venous pressure (CVP) while using a temporary shunt. Five patients underwent a creation of bidirectional Glenn with simultaneous recording of CVP. In the first patient no shunt was used and the CVP rose to 55 mm Hg. Although a temporary shunt was used between innominate vein and the right atrium in the second patient, it did not prevent the sudden increase of CVP which remained at 54 mm Hg.In the last three patients a roller pump was added to the shunt, lowering the CVP to 16-22 mm Hg. It appears that a shunt alone is not reliable for decompressing the superior vena cava during acute clamping and the addition of a pump is a simple way to reduce the CVP.
