Unraveling of a Gianturco coil during reocclusion of a patent ductus arteriosus.

The Gianturco spring coil has been employed in the settling of the small arterial duct and for reocclusion of residual shunts; the ability to manipulate the coil is advantageous for optimal results. This case study reports an associated complication of unraveling of the coil. Careful attention to coil appearance during manipulation and the use of 0.038-inch coils may reduce this risk.
