Comparative Study On Treatment Of Perimembrane Ventricular Septal Defects By The Chest Small Incision Closure Of VSD And By Traditional Surgery

Objective To analysis and discuss the advantages of device closure via a small lower sternal incision of perimembrane VSD and the clinical application value, constantly summarize the clinical experiences. Methods between September2011and February2013. we collected40patients who underwent closure via a small lower sternal incision, another40patients who underwent the conventional surgical repair of perimembrane VSD, aged12months to32years (15.5±3.5years) age with a body weight of10.8to58kg (24.2±7.5kg), the size of perimembrane VSD is2-14mm (5.6±0.5mm).Assessing the superiority and feasibility of closure via a small lower sternal incision by comparing with each other. Results the small incision group was successful in all patients, except for1patient who required immediate surgical conversion after the operation failed (97.5%); the surgical group:all patients are successful in40patients except one patient died of acute infection. the success rate of device closure is similar to the surgical repair.however, there are many significant differences in complications, the determination results of platelet aggregation rate and other related factors. In a follow-up period of3to12months there was no new complications in the small incision group, but, surgical group appeare lots of new complications. Conclusions though the success rate of device closure is similar to the surgical repair, decreasing recovery time, its complications, trauma to the vessels and other relevant factors, it is one of ideal means for the treatment of ventricular septal defect.At present, this technique is feasible, its clinical application value is quite high and the patients are easy to accept it. Certainly, strict anticoagulant therapy and long-term follow-up after surgery is also necessary to confirm the validity of this new technique.
