Nonoperative retrieval of Gianturco coils from abdominal aorta.

Since the original description by Gianturco et al. [1], the stainless steel coil has been widely used in interventional radiology for embolization of medium and large arteries for a variety of indications [2, 3]. Misplacement of a coil in an undesired site is a rare but potentially serious complication , possibly requi ri ng operative removal [4, 5]. I recently encountered this complication in two patients. In one patient, during a preoperative embolization of a left renal tumor, a coil displaced into the abdominal aorta and was successfully retrieved by using a biliary stone removal set (Cook, Inc. , Bloomington, Ind.). In a second patient, a coil was similarly retrieved from the common iliac artery. The technique used in the first patient is described in detail. It is simple and may be a useful addition to the armamentanium of interventional radiologists.
