Post-pneumonectomy patients undergoing cardiac surgery: A case series

Area of Science:

• Cardiothoracic Surgery
• Oncology
• Pulmonary Medicine

Background:

• Limited data exists on cardiac surgery outcomes for patients who have undergone pneumonectomy.
• This study retrospectively analyzed early and late outcomes in post-pneumonectomy patients undergoing cardiac surgery.
• Risk factors for adverse outcomes in this specific patient group were investigated.

Purpose of the Study:

• To evaluate the outcomes of on-pump cardiac surgery in patients with a history of pneumonectomy.
• To identify predictors of poor outcomes in this high-risk surgical population.
• To provide guidance for managing patients requiring cardiac surgery post-pneumonectomy.

Main Methods:

• Retrospective review of an institutional database from 1992 to 2018.
• Inclusion criteria: patients with prior pneumonectomy undergoing on-pump cardiac surgery via median sternotomy.
• Data collected included perioperative events, postoperative complications, and long-term survival.

Main Results:

• Sixteen post-pneumonectomy patients (all lung cancer) were analyzed, with ages ranging from 53-81.
• Major perioperative challenges included structural shifts, extensive adhesions, and calcification.
• Postoperative complications involved respiratory issues, infections, and acute kidney injury. Overall 5-year survival was 50%, with isolated CABG faring better (71%) than CABG+AVR (17%).

Conclusions:

• Cardiac surgery in post-pneumonectomy patients can achieve acceptable outcomes with careful planning.
• Simpler and shorter surgical procedures are associated with more favorable results in this cohort.
• This high-risk subgroup benefits from tailored surgical approaches to improve survival.
