Migration of Nonfibered Packing Coils Used to Treat Peripheral Pseudoaneurysms: Report of 3 Cases
This report describes 3 cases of peripheral pseudoaneurysm embolization with the use of Penumbra packing coils in which coils migrated into the lumens of adjacent viscera: 2 into the duodenum and 1 into the vagina. The coils passed spontaneously in 2 cases and required endoscopic removal in the third. There were no immediate or delayed bleeding or infectious complications following migration. The majority of previously reported coil migration cases have occurred following treatment of pseudoaneurysms adjacent to air-filled structures, and this observation is an important consideration during pretreatment planning.
