The clamshell approach for the surgical treatment of complex cardiopulmonary pathology in infants and children

BACKGROUND: The surgical approach to children with complex cardiovascular and pulmonary anomalies is still controversial. Staged operations through multiple incisions are often performed in this setting. OBJECTIVE: The different applications and clinical advantages of a bilateral thoracosternotomy approach to complex cardiothoracic disease requiring surgical repair were reviewed retrospectively. METHODS: Between January 1993 and June 1995, 33 patients, aged between 2 months and 17 years (mean 7.8 +/- 5.3) underwent surgical treatment of complex cardiovascular or pulmonary disease using a clamshell approach. Twenty-one patients (64%) had undergone 1-5 previous surgical procedures (mean 2.5 +/- 1.0/patient). The technique involved supine position placement, submammary incision, access to the pleural space bilaterally through the fourth intercostal space and transverse division of the sternal body. RESULTS: Four groups of patients were operated on via this approach: (1) patients undergoing lobar, lung or heart-lung transplantation (40%); (2) patients undergoing repair of tetralogy of Fallot/pulmonary atresia (36%); (3) patients with previously corrected miscellaneous procedures (12%), including completion of Fontan, one-stage repair of left main bronchial stenosis and atrial septal defect, one-stage repair of partial anomalous pulmonary venous connection and aortic coarctation, and repair of congenital pulmonary venous stenosis. There were two early (< 30 days) deaths, giving a perioperative mortality of 6% for the entire series. Complications included postoperative hemorrhage in 4 patients (12%), prolonged ventilation time due to mechanical failure in 4 (12%). There were no wound infections. Analysis of complications by group showed the lung transplant group to be more affected (18% of patients experienced complications). Except for 2 infants undergoing complete unifocalization and presently awaiting completion of repair of tetralogy of Fallot/pulmonary atresia, in the remaining 31 (94%) a definitive surgical treatment could be performed in one-stage. CONCLUSIONS: The bilateral thoracosternotomy allows optimal exposure of all intrathoracic anatomic structures making one-stage surgical repair possible in a variety of complex cardiovascular and pulmonary anomalies. Early mortality and technique-related morbidity do not differ from those reported with the conventional approaches to the different disease conditions. A wider application of the clamshell approach for the management of complex intrathoracic pathology in infants and children is advocated.
