Abstract：
Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. The surgical approach to TOF continues to evolve, with many centers now favoring early repair for TOF. This study aimed to determine the prevalence of postsurgical complications such as pulmonary insufficiency, residual pulmonary stenosis, and interventricular communication. Methodology We conducted a cross-sectional, observational study with a descriptive and analytic focus involving 61 patients who were operated on for TOF. Results In total, 39 (63.9%) patients had a regular TOF and 22 (36.1%) had an irregular TOF. In our study, 32 (56.14%) patients had a pulmonary insufficiency, of whom 20 had a minimal pulmonary insufficiency (62.5% of pulmonary insufficiency cases), and 79.4% of patients with right ventricular outflow tract enlargement had pulmonary insufficiency (p < 0.005). Among patients who did not have a right ventricular outflow tract enlargement, three cases of pulmonary insufficiency were identified with a prevalence of 16.6%. Six (10.52%) patients had residual pulmonary stenosis. In addition, two (3.2%) cases of minimal residual ventricular septal defects were identified in this study. Conclusions Postoperative complications of TOF treatment are frequent and require medical care throughout the lifetime of patients.
摘要：
背景法洛四联症(TOF)是最常见的紫蓝色先天性心脏病。TOF的手术方法继续发展，许多中心现在都支持TOF的早期修复。这项研究旨在确定手术后并发症的发生率，如肺功能不全。残余肺动脉狭窄,和室间通讯.方法学我们进行了横断面研究，以描述性和分析为重点的观察性研究涉及61例接受TOF手术的患者。结果总计,39例（63.9%）患者有常规TOF，22例（36.1%）患者有不规则TOF。在我们的研究中,32例(56.14%)患者出现肺功能不全,其中20人患有轻微的肺功能不全（占肺功能不全病例的62.5%），右室流出道扩大患者中79.4%有肺功能不全(p<0.005)。在没有右心室流出道扩大的患者中，发现3例肺功能不全,患病率为16.6%.6例（10.52％）患者有残余的肺动脉狭窄。此外,本研究发现2例(3.2%)微小残留室间隔缺损.结论TOF治疗术后并发症频发，需要患者终生的医疗护理。
