title: Right submammarian thoracotomy in female patients with atrial septal defects and anomalous pulmonary venous connections. Comparison between the transpectoral and subpectoral approaches.
abstract: A right submammarian incision with anterior thoracotomy was performed in 89 female patients to repair simple and complex forms of atrial septal defects. Patients' ages ranged from 8 to 38 years (mean 21.5 years). Seventy-seven had secundum-type atrial septal defects, one had the primum type, and 11 had an associated partial anomalous pulmonary venous connection. The patients were divided into two groups: 57 patients in group A, in whom, after a breast flap was elevated, a transpectoral approach was used to enter the chest; 32 patients in group B, in whom the pectoral muscle was not divided and a subpectoral approach was used. Aortic cannulation was accomplished without difficulty in all 89 patients. There were no early or late deaths in either group. Follow-up ranged from 24 to 108 months (mean 63.7 months) and included 86 patients, who were free of symptoms. In group A, however, among 54 patients examined, the volume of the right breast and pectoral muscle was smaller than the left in four patients (7.4%), and 21 (38.8%) had persistent right periareolar numbness. In 32 patients evaluated in group B, no difference was noted in the size of the breasts, and persistent numbness was present in four patients (12.5%). In summary, atrial septal defects or anomalous pulmonary venous connections can be safely repaired through a right submammarian thoracotomy in female patients. The subpectoral approach offers better results because breast asymmetry and paresthesias are significantly less prevalent (p less than 0.01).
