OBJECTIVES: Off-pump bilateral bidirectional Glenn (b-BDG) poses a surgical challenge and may add complexity to the postoperative
outcome especially regarding uniformity of the anastomosis and central pulmonary artery growth. Herein, we report early- and mid-term
outcomes after off-pump b-BDG without using superior vena cava decompression techniques.
METHODS: Ninety-seven consecutive patients, between 2009 and 2014, were included in this prospective study. All patients had complete
pre- and postoperative clinical and detailed neurological assessments. Diagnosis and follow-up were done by echocardiography and
cardiac catheterization for assessment of pulmonary artery anatomically and haemodynamically. Median follow-up period was 3.5 years.
Perioperative variables, clinical outcome, morbidity, mortality and follow-up data were recorded.
RESULTS: Hypoplastic right ventricle was present in 52 cases (53.6%) and hypoplastic left ventricle was present in 45 cases (46.4%). Mean
superior vena cava pressure on clamping was 21.49 ± 3.04 mmHg. Mean total clamping time was 23.11 ± 3.44 min. Mean oxygen saturation
increased from preoperative 69.22 ± 6.01% to 83.66 ± 3.97% after b-BDG construction (P-value |
