  • Minimal Right Vertical Infra-axillary Incision for Subarterial Ventricular Septal Defect Closure in Children

    ObjectiveTo summarize clinical results and experience of subarterial ventricular septal defect (sVSD) closure through a minimal right vertical infra-axillary incision in children, and evaluate the feasibility of this technique. MethodsClinical data of 27 sVSD patients who underwent surgical repair through a minimal right vertical infra-axillary incision from March 2009 to January of 2013 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 20 male and 7 female patients with their age of 1.1-11.0 (4.4±2.8) years and body weight of 7.6-28.0 (14.6±5.3) kg. After induction of anesthesia, the patients were placed in a 90 degree left lateral position. The incision was performed along right midaxillary line vertically between the superior border of the third rib and inferior border of the fifth rib. The thoracic cavity was entered through the fourth intercostal space. The pericardium was opened 2 cm anterior to the phrenic nerve and suspended to elevate the heart and great vessels by the pericardial traction sutures. Cardiopulmonary bypass (CPB) was established after cannulation of the ascending aorta, superior vena cava and inferior vena cava. Closure of sVSD was performed through longitudinal pulmonary incision. After procedures under CPB finished, the aortic cannula was removed and the pericardium was closed with interrupted sutures. The thoracic drainage tube was placed through the sixth intercostal space. All the patients were followed up 3, 6 and/or 12 months after surgery. Satisfactory degree of the patients and their relatives were evaluated. Chest X-ray, electrocardiography and echocardiography were examined. ResultsSurgical repair of sVSD was performed in all the patients through this incision without any difficulty, incision prolongation or conversion to another incision. There was no in-hospital death, reexploration for bleeding, postoperative atelectasis, pulmonary infection, pleural effusion, impairment of central nervous system, phrenic nerve damage, poor wound healing, wound infection or pericardial effusion. Incision length was 4.4-7.0 (5.07±0.66) cm. Echocardiography before discharge showed no residual shunt in all the patients. All the patients were followed up 3, 6 and/or 12 months at the outpatient department or via the phone. During follow-up, there was no late death, residual shunt or chest asymmetry. The short incision under the armpit was obscured and provided favorable cosmetic results. All the patients and their relatives were satisfied with the cosmetic results. ConclusionRepair of sVSD through a minimal right vertical infra-axillary incision is feasible and safe for children. The advantages of this technique are favorable for children with sVSD.

  • Mid-term follow-up of perventricular device closure of subarterial ventricular septal defect

    ObjectiveTo evaluate the mid-term safety, efficacy and feasibility of perventricular device closure for subarterial ventricular septal defect.MethodsClinical data of 97 patients diagnosed with subarterial ventricular septal defect through echocardiography in West China Hospital from September 2013 to December 2015 were retrospectively analyzed. There were 66 males and 31 females aged 3 (1.8, 5.9) years. All the patients underwent perventricular device closure under the guidance of transesophageal echocardiography using eccentric occlusion device. Possible complications such as residual shunt, valvular regurgitation, atrioventricular conduction block and arrhythmias were recorded during the 1-year, 3-year and 5-year follow-up.ResultsAll the patients received perventricular device closure successfully except that 1 patient underwent open surgical repair under cardiopulmonary bypass 3 months later because of the migration of device. So the rate of complete closure was 99.0%. No residual shunt, moderate or severe valvular regurgitation, atrioventricular conduction block or arrhythmias were observed 5 years later.ConclusionTreating subarterial ventricular septal defect through perventricular device closure exhibits remarkable mid-term efficacy, safety and feasibility with high success rate.
