The bidirectional Glenn (BDG) shunt operation serves as temporary treatment of single-ventricle physiology before the eventual Fontan procedure. Some cases can be performed without the support of a cardiopulmonary bypass (CPB) machine. In this study, we present the surgical outcomes of off-pump BDG operations with the use of temporary veno-atrial shunt to decompress the superior vena cava (SVC) during clamping. | JOURNAL OF MEDICAL RESEARCH BIDIRECTIONAL GLENN OPERATION WITHOUT CARDIOPULMONARY BYPASS: OPERATIVE PROTOCOL AND EARLY RESULTS Nguyen Tran Thuy¹, Ngo Thi Hai Linh¹, Doan Quoc Hung² ¹Cardiovascular Center, E Hospital ²Hanoi Medical University The bidirectional Glenn (BDG) shunt operation serves as temporary treatment of single-ventricle physiology before the eventual Fontan procedure. Some cases can be performed without the support of a cardiopulmonary bypass (CPB) machine. In this study, we present the surgical outcomes of off-pump BDG operations with the use of temporary veno-atrial shunt to decompress the superior vena cava (SVC) during clamping. From June 2013 to June 2015, 23 patients underwent off-pump BDG operations at Cardiovascular Center, E Hospital. All patients were operated on using a venoatrial shunt to decompress the SVC. Satisfactory results with mean oxygen saturation increased from ± % to ± %. The superior vena cava (SVC) clamping time was 14 ± minutes (ranging from 12 to 21 minutes). No neurological complications or deaths occurred after the surgery and the postoperative period was uneventful. In conclusion, the use of venoatrial shunt to decompress SVC during the off-pump BDG operation is safe and produces good surgical outcomes. Its wider adoption can the deleterious effects associated with CPB. The operation is easily reproducible at low cost and overcome.

INTRODUCTION Bidirectional Glenn shunt operation is performed as the initial step in the treatment of functional single-ventricle physiology before the completion of the Fontan procedure. The purpose of this surgery is to provide balanced venous blood flow into two pulmonary arteries for oxygenation, as Corresponding author: Nguyen Tran Thuy, E Hospital Email: drtranthuyvd@ Received:09 May 2017 Accepted: 16 November 2017 JMR 111 E2 (2) - 2018 oppoed to .
