Right postero-lateral thoracotomy for atrial septal defect closure; a comparative analysis with median sternotomy

Introduction In a low risk procedure like ASD closure Right Posterolateral thoracotomy approach aims at the cosmetic results as compared to median sternotomy. This paper illustrates our approach for a standardised Right Posterolateral thoracotomy in ostium secundum ASD repair and the analysis of the outcome. Methods Right Posterolateral thoracotomy (RPLT) was offered as a cosmetic alternative for atrial septal defect (ASD) closure in children, and selected adult patients below 30 years with lean body build. A retrospective study comparing these patients with median sternotomy approach during the same period (2000–2003) was performed. Exclusion criteria included preoperative diagnosis of complex ASD, obesity and chest wall deformity. Common variables were considered for analysis. Results There were 96 patients (66 females and 30 males) with an average age of 13yrs (range 3 to 27 years) in RPLT group and 225 patients (95 females and 130 males) with average age of 36 years (range 2 to 46 years) in sternotomy group. Extra corporeal time was 32 minutes (28 to 45) and aortic cross clamp time was 14 minutes (8 to 36) in RPLT while the values were 46 minutes (37 to 90) and 22 minutes (18 to 36) in Median sternotomy approach. Blood loss in postoperative period was 160 ml (20 ml to 400 ml) in thoracotomy group compared to 210 ml (40ml to 600 ml) in sternotomy group. There was no mortality or recurrence after repair of ASD during the follow-up. Significant postoperative morbidity was persisting pain and shoulder movement restriction in 12 patients. The scar was cosmetic in RPLT. Conclusion In selected patients with lean body build Right posterolateral thoracotomy is suitable for ostium secundum atrial septal defect closure. The final appearance has definite cosmetic advantage over sternotomy. Presented at the 50^th Annual Meeting of IACTS, New Delhi, Feb., 2004.
