BACKGROUND: Limited data have reported the outcomes of percutaneous closure of patent ductus arteriosus (PDA) in patients with unilateral absence of pulmonary artery (UAPA). This study aimed to evaluate the symptomatology, diagnosis and therapy, especially the transcatheter closure of PDA in patients with PDA associated with UAPA.
MATERIALS AND METHODS: Patients diagnosed with PDA and UAPA were retrospectively enrolled from August 2010 through January 2016. Clinical data, treatment and follow-up information were evaluated.
RESULTS: Thirteen patients (6 males and 7 females) were diagnosed with PDA associated with UAPA. Percutaneous closure was successfully conducted in 6 patients successfully. The median age was 7 years (7 months to 37 years). The mean diameter of the PDA and occluders were 4.7 ± 1.8mm (2-7mm) and 11.3 ± 3.9mm (6-14mm), respectively. The mean pulmonary artery pressure was 41.5 ± 13.5mmHg (25-62mmHg). The diameter of PDA has no relationship with the degree of pulmonary artery pressure (r = 0.239, P = 0.648). In 4 patients, systolic pulmonary arterial pressure decreased significantly after closure with 69.0 ± 10.7 versus 48.0 ± 11.3mmHg (P = 0.146), and also the mean pulmonary arterial pressure was 54.5 ± 5.7 mm Hg versus 30.5 ± 3.9mmHg (P = 0.04). In all, 1 patient had a trace residual shunt, which disappeared within 24 hours.
CONCLUSIONS: In appropriate patients with PDA associated with UAPA, transcatheter closure of PDA has the potential to improve the pulmonary artery hypertension. Further follow-up is required to monitor the long-term outcomes.
