目的:报道使用国产封堵器介入治疗嵴内型室间隔缺损(VSD)的体会。方法:嵴内型VSD患者15例,行介入封堵治疗,根据缺损上缘距主动脉右冠瓣距离分:≥0～<1mm(A组)、≥1～<2mm(B组)、≥2～≤3mm(C组),依此制定封堵策略,选择封堵器和封堵方式。结果:①15例患者封堵成功率100%,无并发症发生;②15例嵴内型VSD患者A组3例,B组8例,C组4例;③根据缺损口大小及分组分别使用零偏心型、偏心型、对称型封堵器均封堵成功;④改良猪尾导管在嵴内型VSD封堵术中效果显著。结论:国产封堵器介入封堵嵴内型VSD安全、有效、并发症少、费用低,可作为有封堵适应证VSD患者的首选。
OBJECTIVE: To report the experience of interventional treatment of intracortical ventricular septal defect (VSD) with domestic occluder. Methods: Fifteen patients with intracristal VSD were involved in the treatment of occlusion. According to the distance from the upper edge of the defect to the right coronary artery of the aorta: ≥0 ~ <1mm (group A), ≥1 ~ <2mm (group B), ≥ 2 ~ ≤ 3mm (C group), in accordance with the development of closure strategy, select the occluder and closure mode. Results: ① The successful rate of occlusion was 100% in 15 patients without complications; ② 15 patients in group A had 3 patients in group C, 8 patients in group B and 4 patients in group C; ③ According to the size of the defect and grouping, Type, eccentric, symmetric occluder are blocked successfully; ④ improved pig tail catheter in the ridge type VSD closure surgery was effective. CONCLUSION: The domestic occluder is safe and effective in blocking the intracranial crestal VSD. It has less complications and low cost and can be used as the first choice of patients with VSD with occluder indications.
