Key result
Snare loop technique successfully retrieves trapped or broken PTCA guidewires in two cases.
The snare loop technique is a viable percutaneous method for retrieving broken or unwound PTCA guidewires.
May facilitate percutaneous retrieval of damaged PTCA guidewires; hypothesis-generating and should not change practice without further data.
Two cases are described of percutaneous removal of trapped, broken steerable PTCA guidewire. One case described breakage of a guidewire inside the ascending aorta leaving a free end, which is retrieved using the snare loop technique. The second case described retrieval of an intact yet unwound wire through the guiding catheter using a snare loop wire.

Linley E. Watson (1987) studied this question. The snare loop technique successfully enabled the percutaneous retrieval of trapped, broken, or unwound steerable PTCA guidewires in two reported cases.
