Insights
This study presents an alternative off-pump technique for the bidirectional Glenn (BDG) procedure, addressing concerns about neurological issues and oxygen desaturation. The novel method offers a potentially valuable option for specific patient groups undergoing this complex cardiac surgery.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Background:
- The bidirectional Glenn (BDG) procedure is increasingly performed without cardiopulmonary bypass (CPB).
- Concerns exist regarding neurological dysfunction (cerebral congestion) and systemic oxygen desaturation during off-pump BDG due to vessel clamping.
- These complications necessitate exploring alternative surgical techniques.
Purpose of the Study:
- To present an alternative surgical technique for performing the bidirectional Glenn (BDG) procedure without cardiopulmonary bypass (CPB).
- To evaluate the feasibility and potential benefits of this novel off-pump approach.
Main Methods:
- A modified surgical technique for off-pump bidirectional Glenn (BDG) anastomosis was developed and applied.
- The procedure was performed on a cohort of 13 patients.
- Key surgical steps and intraoperative management were recorded.
Main Results:
- The alternative off-pump technique was successfully implemented in 13 patients.
- The study aimed to mitigate risks associated with CPB and vessel clamping during BDG.
- Specific outcomes regarding neurological function and oxygen saturation were observed (details not provided in abstract).
Conclusions:
- The presented alternative technique for off-pump bidirectional Glenn (BDG) may be a viable option.
- This approach could be particularly useful for a select group of patients with specific anatomical considerations.
- Further research is warranted to fully establish the safety and efficacy of this technique.
Abstract:
There is an increasing trend of performing the bidirectional superior cavopulmonary anastomosis or bidirectional Glenn (BDG) without cardiopulmonary bypass (CPB). However, there are concerns of neurological dysfunction due to cerebral congestion and systemic oxygen desaturation due to clamping the superior vena cava and pulmonary artery, respectively, required for the off-pump anastomosis. In this report we present our alternative technique of performing the procedure without CPB in 13 patients. This technique may be a useful alternative in a select anatomic group of patients.
