Use in children of an additional umbrella for transcatheter occlusion of residual patency of the arterial duct following initial insertion of an umbrella device
Published online by Cambridge University Press: 19 August 2008
Summary
After an initial attempt to close arterial ducts by the transcatheter insertion of an umbrella device had left significant residual patency, further attempts at closure were made in 14 patients by the insertion of an additional umbrella device. The ages of the patients ranged from four to 11 years. Overall, 17 attempts were made to insert additional devices at intervals of between six to 26 months after the insertion of the first umbrella. Successful insertion of a device was achieved in two patients only at a third attempt. One patient required the insertion of a third umbrella to achieve complete occlusion of the patent duct. Complete closure of the residual patency was achieved in 13 of the 14 patients. The remaining patient has been scheduled for insertion of a third umbrella.
