特殊类型动脉导管未闭的介入治疗(附30例报告)

Transcatheter closure of special types of patent ductus arteriosus

目的:探讨特殊类型动脉导管未闭(patentductusarteriosus,PDA)介入治疗的方法。方法:应用蘑菇伞封堵器(patentductusarteriosusoccluder,PDAO)介入封堵特殊类型的PDA30例。结果:30例中巨大PDA5例[最窄径平均12.4±1.7mm(10.1～16.3mm)],细小PDA15例(最窄径平均2.10±0.42mm),外科手术后再通的PDA6例(最窄径平均3.20±0.34mm),伴重度肺动脉压增高的PDA3例[(平均肺动脉压88±7mmHg(75～97mmHg)],合并严重脊柱侧弯畸形1例。对5种不同类型的PDA根据其不同特点,采取不同的方法均成功封堵。结论:对于特殊类型动脉导管未闭选择恰当的方法可成功封堵。

Objective： To discuss the method of the transcatheter closure of special types of patent ductus arteriosus （PDA）. Methods：30 patients special types of PDA accepted transcatheter closure using patent ductus arteriosus occluder （PDAO）. Results： Among the 30 cases,5 were with large PDA （The mean PDA of minimal diameters was12.4 ± 1.7 mm （ranged 10.1 to 16.3 mm）, 15 were with small PDA （The mean PDA of minimal diameters was 2.1 ± 0.42 mm）,6 were with recanalization after surgical closure （The mean PDA minimal diameter was 3.20± 0.34 mm）,3 were with severe pulmonary hypertension [The mean pulmonary pressure was 88 ± 7 mmHg （75-97 mmHg）]and 1 was with severe scoliosis. Different ways were taken successfuly in the closure of 5 special types of PDA. Conclusion：Special types of PDA may be closed successfully by choosing a proper device.
