在临床上具有特征性杂音的动脉导管未闭诊断不困难且手术治疗效果良好,但约占5％的病例因合并有较明显的肺动脉高压,而杂音不典型,术前常被诊断为其他先天性心脏病,若此类患者在手术前能作出明确的诊断,虽有肺动脉高压而不伴有逆向分流,或仅有轻度的逆向分流者进行手术治疗仍能获得良好的效果。本文对58例动脉导管未闭的患者中经外科手术及/或心导管术检查证实诊断的21例病例进行临床分析,对不典型杂音动脉导管未闭的诊断问题加以讨论。
Patent ductus arteriosus with clinically characteristic noises is not difficult to diagnose and has good surgical outcomes. However, about 5% of patients have pulmonary hypertension complicated with atypical murmur and are often diagnosed as other congenital diseases before surgery If you have a definite diagnosis of a heart attack before surgery, you can still get good results even if you have pulmonary hypertension without reverse shunting, or if you have only mild adverse shunting. In this paper, 58 cases of patients with patent ductus arteriosus confirmed by surgical and / or cardiac catheterization in 21 cases of clinical analysis of the diagnosis of atypical cusp ductus arteriosus to be discussed.
