[The "umbrella closure" of the ductus arteriosus]

The technical details of the method are outlined, and the Norwegian experience reported: From September 1988 to January 1994 we attempted to close open ducts with the Rashkind technique in 26 patients. Two ducts were too small to accept the device, and in one case the implanted device could not be released. This patient was referred to surgery. In the remaining 23 patients the device was left in place. The mean X-ray fluoroscopy time was 15 minutes. No complications occurred. In eight patients (35%) a residual shunt could be detected by ultrasonic Doppler technique, but in seven of them haemodynamical significance was lacking. The umbrella method is a good alternative to traditional treatment.
