Transcatheter retrieval of an Amplatzer Vascular Plug.

INTRODUCTION: An Amplatzer Vascular Plug (AVP), which was designed as a permanent occluding device derived from the Amplatzer Septal Occluder and Amplatzer Duct Occluder, is a useful embolic device that can be precisely deployed in medium to large vessels with high resistance to migration. However, migration of these Amplatzer devices has been reported as a relatively rare but major complication. CASE REPORT: A 59-year-old woman was referred for the treatment of advanced pancreatic body cancer; after systemic chemotherapy, distal pancreatectomy with en bloc celiac axis resection (DP-CAR) was planned as curative treatment. Therefore, preoperative embolisation of the common hepatic artery (CHA) for arterial redistribution was performed. Although a 6-mm AVP II was deployed at the mid-portion of the CHA, the AVP migrated to the proper hepatic artery. Although migrated AVP retrieval using a goose neck snare was attempted, it was impossible to retrieve it into the 5-F guiding sheath. Therefore, the AVP was delivered to the splenic artery, which was planned to be resected in DP-CAR. Finally, a 10-mm AVP II was redeployed at the proximal portion of the CHA, and complete occlusion was achieved.
CONCLUSIONS: When AVP retrieval is not possible, delivery to the other arteries having lesser influence might be an alternate technique.
