We are writing to inform the readers and editors of the Archives that we have discovered errors in our article titled “Prevalence of Fracture and Fragment Embolization of Bard Retrievable Vena Cava Filters and Clinical Implications Including Cardiac Perforation and Tamponade.”1 The 189 patients described in the published study were identified from general surgery and interventional radiology logs and were a subset of all patients who underwent implantation of vena cava filters between 2004 and 2009.1 Despite requesting complete patient lists from each division, a log of radiology patients who received the Bard G2 filter (Bard Peripheral Vascular) at York Hospital between January 2007 and January 2009 was not made available to investigators, and therefore these patients were not included in the fluoroscopy study. A copy error in Figure 2 incorrectly stated that 83 patients agreed to fluoroscopy. The correct number is 80, as reported in the text, abstract, and statistical calculations of the article. In Table 2, 4 different physicians implanted filters, which went on to fracture, with 10 of these devices implanted by the same physician. While these issues do not have significant bearing on the results reported in our study and do not change our conclusions, we thought that they should be disclosed.
