IntroductionThe prevalence of life-threatening complications (LTCs) related to the minimally invasive repair of pectus excavatum (MIRPE) is unknown and underreported. The aim of this study is to contribute to the real prevalence of these rare but dramatic complications and show what went wrong in order to prevent it in the future.Case presentationA 15-year-old boy affected by pectus excavatum with severe asymmetric deformity of the chest wall was evaluated for elective corrective surgery. Preoperative computed tomography showed a Haller index of 5.7 and a correction index of 0.40. MIRPE was performed under right video-assisted thoracoscopy. Cardiac arrhythmias occurred after placement of the bar introducer. The introducer was removed, and massive bleeding was noted. Emergency Clamshell thoracotomy was performed, and cardiac surgeon was alerted immediately. A first pulmonary wound was found and controlled. Two cardiac lacerations were found: on the interventricular wall and on the right atrium. Under cardiopulmonary bypass, cardiac lacerations were sutured and other three pulmonary wounds were repaired. An urgent fasciotomy was performed for compartmental syndrome of the right lower art after femoral cannulation. Pulmonary distress occurred; the patient was admitted on ECMO (ExtraCorporeal Membrane Oxygenation) in intensive care unit. Right lower lobectomy was carried out on the fifth postoperative day due to massive pulmonary bleeding requiring temporary tracheostomy. The patient was discharged to rehabilitation after 3 months with no brain injuries, minor hearing loss, and tracheostomy.ConclusionWe want to maintain the high alertness required for this procedure. Reporting these scaring complications contributes to the real prevalence of LTCs. We suggest the use of bilateral thoracoscopy and crane elevator in severe sternal defects. We also suggest to have a cardiac surgeon available in the hospital owing to cardiac perforation.
