CANEO, Luiz Fernando et al. Senning operation with autologous tissue for atrial septum augmentation or pulmonary venous pathway enlargement. Rev Bras Cir Cardiovasc [online]. 1999, vol.14, n.4, pp. 298-302. ISSN 0102-7638. http://dx.doi.org/10.1590/S0102-76381999000400004.
One of the main theoretical advantages of the original Senning Operation is the ability to avoid either biologic or synthetic patches for atrial septum augmentation or to enlarge pulmonary venous pathways. To accomplish this we have performed the Senning procedure with some modifications that allow the operation to be completed without the use of heterologous tissue. Twelve children, aged 5 months to 4 years (mean age: 20 months) with transposition of great arteries who had previous balloon atrial septostomy were submitted to the Senning procedure. The following associated lesions were diagnosed: ventricular septal defect in 1 patient, valvular pulmonary stenosis in 1 and auricular juxtaposition in 1. The modified technique used for atrial septum augmentation was the use of open inverted left auricula in 5 cases, inverted auricula in 2 and in situ autologous pericardium for venous pathway enlargement in 5. The hospitalization was 10 to 24 days (mean = 15 days) and the post-operative period was 7 to 22 days (mean = 12 days). There were no in-hospital or late deaths during a mean follow-up period of 23 months (range 8 to 34 months). All patients had a good clinical outcome and their follow-up echocardiographic examinations showed no evidence of venous pathway obstruction. This modified Senning Operation can be performed without either biologic or synthetic patches for atrial septum augmentation or to enlarge pulmonary venous pathway. The use of autologous in situ tissues with potential for growth, retains the main theoretical advantage of the original technique.
