Spring coil retraction in coil occlusion of persistent ductus arteriosus

Spring coil retraction in coil occlusion of persistent ductus arteriosus.

AIMS To present the short and intermediate term results of coil occlusion of persistent ductus arteriosus and the results of radiographic measurements of spring coils implanted to treat patent ducts. PATIENTS 22 children underwent coil occlusion. Their ages ranged from 2 years 9 months to 12 years 10 months (mean (SD) age, 6.5 (3.6) years). The duct diameter ranged from 1.0 to 3.5 mm at the n...

Closure of Small Patent Ductus Arteriosus by Occluding Detachable Coil

Open-Coil Retraction Spring

Sliding mechanic has become a popular method for space closure with developments in preadjusted edgewise appliance. Furthermore, various space closing auxiliaries have been developed and evaluated extensively for their clinical efficiency. Their effectiveness enhanced with optimum force magnitude and low-load deflection rate (LDR)/force decay. With the advent of NiTi springs in orthodontics, LD...

CASE REPORT Recanalisation after coil embolisation of persistent ductus arteriosus

A 5 year old girl underwent recanalisation after coil embolisation of a persistent ductus arteriosus. Recanalisation is uncommon after coil embolisation and may be related to shrinkage of the coil, a change in its position, and ductal shape. (Heart 1998;79:308–310)
