RESUMO

Background: Minimally invasive repair of pectus excavatum involves placement of retrosternal support (Nuss) bars. Hardware removal has been rarely associated with life-threatening hemorrhage from the heart, aorta, internal mammary arteries, and/or lung. There is no accepted standard intraoperative monitoring technique used during removal. We hypothesized that the use of transesophageal echocardiography (TEE) during Nuss bar removal would enhance safety of the procedure and be cost-effective. Methods: IRB-approved retrospective review of patients who underwent Nuss bar removal with intraoperative TEE monitoring over a 4-year period, from March 2013 to May 2017, was completed. Bar removal procedures were performed supine, under general anesthesia. TEE images were monitored and any distortion of the cardiac silhouette, new pericardial effusion, and/or cardiac arrhythmias would be considered evidence of possible bar adherence, triggering possible conversion to sternotomy or thoracotomy. Results: In total, 87 consecutive patients, mean age of 20 years, were identified. Bars had been in place for a mean of 30 months. Average procedure time was 67 minutes. No patients experienced arrhythmias, cardiac injury, or significant hemorrhage during removal. TEE gave excellent visualization of the cardiac silhouette and pericardium in all cases. No patient required insertion of an arterial line, a postoperative chest X-ray, or overnight hospitalization. Patients were discharged from the recovery room an average of 89 minutes postprocedure. Conclusion: TEE offers a minimally invasive safe way to visualize the pericardium and its contents during Nuss bar removal. Significant cardiac/mediastinal injuries should be immediately visible. The use of TEE is cost-effective and allows safe discharge the day of surgery.
