title: A complication of the Greenfield filter: fracture and distal migration of two struts--a case report.
abstract: This is a case report of a 41-year-old woman who required surgical removal of a Greenfield filter 7 months after placement. The filter developed several complications. Two struts were noted to be completely separated from the filter and lodged in the infrarenal vena cava. The filter had migrated to a resting position in the right renal, vein with two struts perforating the renal vein and inferior vena caval junction. The perforating struts were intraperitoneal and were found to impinge on the right ureter with seromuscular involvement of the second portion of the duodenum. No free perforation was noted at the time of exploration.
