영아기 심실중격결손 봉합술의 임상적 고찰

Clinical Analysis of Patch Repair of Ventricular Septal Defect in Infant

단순 심실중격결손증은 선천성 심질환중 흔한 질환이지만 어린 나이 혹은 저체중환아에서 시행하는 경우 경험에 따라 만족스럽지 못한 경우도 있어 영아기에 수술을 시행한 단순 심실중격결손증 환자들의 수술 결과를 조사하였다. 1996년부터 2000년까지 첩포봉합술을 시행한 45명을 대상으로 체중 5 kg을 기준으로 수술의 결과를 분석하였다. 수술사망은 없었으며 두 군간의 합병증 발생에 있어 유의한 차이는 없었다. 수술 수기로 사용된 단순 연속봉합법은 전례에서 적용할 수 있었으며 증상이 있는 심실 중격결손증은 체중이 5kg이하의 환아에서도 시기에 관계 없이 안전하게 시행할 수 있었다.

Background: Simple ventricular septal defect(VSD) is the most common congenital heart disease. Although closure of VSD is currently associated with a relatively low risk, experience with younger and smaller infants has been variably less satisfactory. We assessed the results of surgical closure of VSD in infant. Materials and Methods: Between 1996 and 2000, 45 non-restrictive VSD patients underwent patch repair and retrospective analysis was done. Patients were divided into two groups based on weight: group I infants weighed 5kg or less(n=16), and group II infants weighed more than 5kg(n=29). Both groups had similar variation in sex, VSD location, aortic cross clamp time and total bypass time. But combined diseases (ASD, PDA, MR) were more in group I. We closed VSD with patch and used simple continuous suture method in all patients. Results: There were no operative mortality, no reoperation for hemodynamically significant residual shunt and no surgically induced complete heart block. As a complication, pneumonia(group I: 2 cases, group II: 2 cases), transient seizure(group II: 2), wound infection(group I: 1, group II: 1), urinary tract infection(group I: 1) and chylopericardium(group I: 1) developed, and there was no significant difference between two groups(p>0.05). Conclusion: Early primary closure with simple continuous suture method was applicable in all patients with non-restrictive VSD without any serious complications.
