[Evaluation of sternal deformity after pediatric minimally invasive cardiac surgery].
Sternal shape is one of the most important esthetic factors of the chest appearance after pediatric minimally invasive cardiac surgery (pMICS) as well as length of skin wound. We evaluated the grade of postoperative sternal deformity in 20 patients who underwent total repair of pediatric congenital heart disease [atrial septal defect (ASD): 17, ventricular septal defect (VSD): 2, partial anomalous pulmonary venous connection (PAPVC): 1] with minimal skin incision and lower partial median sternotomy. The sternum was closed with stainless wire in 3 patients, with absorbable polydioxanone (PDS) cord in 5 patients, with combined use of reabsorbable radiolucent poly (L-lactate) acid sternal pin and absorbable PDS cord in 12 patients. The evaluation of postoperative sternal deformity was made according to the vertebral index (VI) and frontosagittal index (FSI) in 3 groups with each sternal closure method. VI and FSI of the 3 groups showed no significant difference. Sternal deformity in the group with sternal closure with PDS cord group was more severe than that in other 2 groups. The combined use of sternal pin with PDS cord offered the most sufficient fixative strength for sternal closure.
