Objective: The objective of this study was to evaluate complications of Greenfield (Boston Scientific, Marlborough, Mass) stainless steel inferior vena cava (IVC) filters on follow-up computed tomography (CT) imaging and to elucidate associated risk factors.
Methods: Ninety-three patients with CT studies obtained for other reasons after Greenfield IVC filter placement (2007-2014) were retrospectively studied. Greenfield filters were placed permanently in those with venous thromboembolism and an expected lifelong contraindication to anticoagulation or life expectancy <6 months.
Objective: The objective of our study was to report the technique, complications, and clinical outcomes of interventional radiology-operated cholecystoscopy with stone removal for the management of symptomatic cholelithiasis.
Materials And Methods: Ten (77%) men and three (23%) women (mean age, 65 years) with symptomatic cholelithiasis underwent cholecystostomy followed by interventional radiology-operated cholecystoscopy with stone removal. Major comorbidities precluding cholecystectomy included prior cardiac, pulmonary, or abdominal surgery; cirrhosis; sepsis with hyponatremia; seizure disorder; developmental delay; and cholecystoduodenal fistula.
Aortoenteric fistulae are life-threatening conditions characterized by abnormal communications between the aorta and gastrointestinal tract. Aortoenteric fistulae may be characterized by the triad of bleeding, abdominal pain, or a pulsatile abdominal mass. Although hemorrhage is the most common presentation, it does not always occur; thus, patients may present with nonspecific symptoms.

Materials And Methods: Single-center retrospective review of 35 patients who had an IVCF placed following organ transplantation. Patient demographics, IVCF indication, and eligibility for retrieval were reviewed.
Purpose: To identify risk factors for strut perforation following Celect inferior vena cava (IVC) filter (IVCF) placement and to use finite element modeling to predict the mechanical impact of long-dwelling filters.
Materials And Methods: Ninety-one patients with three computed tomography (CT) studies were evaluated following Celect IVCF placement (2007-2013). Three-dimensional finite element models of the Celect IVCF were developed to simulate mechanical deformation of the IVCF encountered in vivo.
Purpose: To evaluate and compare the rates of complications on follow-up computed tomography (CT) studies of patients with Celect, Günther Tulip, and Greenfield inferior vena cava (IVC) filters.
Materials And Methods: Retrospective review of CT studies obtained 0-1,987 days after infrarenal placement of an IVC filter identified 255 Celect, 160 Tulip, and 50 Greenfield filters. Follow-up CT studies were independently evaluated by two observers for IVC perforation, contact with adjacent organs, and filter fracture.
