Bidirectional Glenn procedure with and without cardiopulmonary bypass: Short term results

Early outcomes after the on pump bidirectional Glenn procedure: A single center experience

OBJECTIVE

Bidirectional Glenn procedure is a staged palliative procedure for patients with the univentricular hearts or complex congenital heart disease. We in our study, attempted to evaluate the preoperative characteristics, operative data and the early postoperative outcomes in the patients who underwent Bidirectional Glenn procedure at our center.

METHODS

In our single center retrospective experience, 115 patients underwent Bidirectional Glenn procedure from January 2015 to December 2019.

RESULTS

The mean age of the patients was 6.55 ± 6.5 years (range from 9 months to 48 years) and a median of 5 years. The most common anatomic diagnosis was double outlet right ventricle (n = 49, 42.6%). The primary diagnosis and the additional cardiac anamolies were not associated with the adverse outcomes. The increased cardiopulmonary bypass and operative time affect the postoperative outcomes. The median oxygen saturation in the patients postoperatively was 82%. The median postoperative stay was 8 days. The early postoperative complications were seen in 29 patients (25.2%). There were 12 early deaths (10.4%) in our study. The late age of presentation and poor preoperative nutrition, increased the risk of the postoperative morbidity and mortality.

CONCLUSION

Bidirectional Glenn procedure is an effective procedure to improve efficacy of the gas exchange and reduce volume overload on the single ventricle at early as well as late stages. However, the late age of presentation increases the risk of the postoperative outcomes.
