Bt. Hwang et al., Comparison of the one-and-a-half-year results of closure of patent ductus arteriosus by transcatheter coils placement with surgical ligation, ANGIOLOGY, 51(9), 2000, pp. 757-763
Patent ductus arteriosus (PDA) is a common type of congenital cardiovascula
r lesion. It usually needs surgical ligation in a full-term baby after 1 ye
ar of age. Transcatheter implantation of coils was introduced for the closu
re of small- to moderate-sized PDA in 1992. From November 1995 to November
1998, the authors closed the PDA in 153 patients by transcatheter implantat
ion of coils and by surgical ligation in 10 patients. One hundred fourteen
of them were studied for more than 11/2 years. The regular followup studies
, including physical examination; electrocardiography; and pulsed, continuo
us-wave, and color Doppler flow mapping, were performed on day one and day
2, and 1 week, 1 month, 3 months, 6 months, and 1 year after the procedure.
The results of the closure of PDA by surgical ligation or coil placement w
ere compared and analyzed in all the patients.
