Patient allegedly received an implant on (b)(6)2007 via the right internal jugular vein for prophylaxis against pulmonary embolism (pe).Patient is alleging tilt, vena cava perforation, organ perforation, and ivc filter clotted.Report from ct (computed tomography): "there is an inferior vena cava filter present.Multiple support legs have eroded through the lumen of the inferior vena cava into the adjacent soft tissues.One of these legs as focally eroded into the lumen of the abdominal aorta, the tip projects approximately 4 mm intervals lobe and is surrounded by a small volume of hyperdense material, likely to represent chronic thrombus.There is approximately 22 degrees posterior tilt of the inferior vena cava filter relative to the inferior vena cava.The abdominal aorta is normal in caliber without evidence of aneurysmal dilatation.As stated above, there is focal perforation of inferior vena cava filter leg into the lumen of the abdominal aorta, the perforation is located just above the aortic bifurcation to the right of the midline.".

The following fields were updated per additional information received: a2, a4, b1, b5, b6, d1, d4, g5, h4, h6.H6 device code(s): appropriate term/code not available (3191) was selected for the alleged device perforation and tilt.Investigation: investigation is reopened due to additional information provided.The reported allegations have been further investigated based on the information provided to date.The following allegations have been investigated: vena cava (vc)/organ/aorta perforation, filter thrombus, tilt.Filter interacts with ivc wall, e.G.Penetration/perforation/embedment.This may be either symptomatic or asymptomatic.Potential causes may include improper deployment; and (or) excessive force or manipulations near an in-situ filter (e.G., a surgical or endovascular procedure in the vicinity of a filter).Potential adverse events that may occur include, but are not limited to, the following: trauma to adjacent structures, vascular trauma, vena cava perforation, vena cava penetration.Ivc occlusion/ thrombosis, new dvt, ivc stenosis as a reported complication, is a known risk in relation to filter implant and is well documented in the clinical literature and in clinical practice guidelines.This is supported by the clinical evidence report established to assess available clinical data to identify and evaluate the clinical safety and performance of the cook vena cava filters.Potential adverse events that may occur include, but are not limited to, the following: vena cava occlusion or thrombosis, vena cava stenosis, deep vein thrombosis.Filter tilt has been reported.Potential causes may include filter placement in ivcs with diameters larger than those specified in these instructions for use; improper deployment; manipulations near an implanted filter (e.G., a surgical or endovascular procedure in the vicinity of a filter); and (or) a failed retrieval attempt.Excessive filter tilt may contribute to difficult or failed retrieval; vena cava wall penetration/perforation; and (or) result in loss of filter efficiency.Potential adverse events that may occur include, but are not limited to, the following: unacceptable filter tilt.10 devices in lot.No relevant notes on work order.The product is manufactured and inspected according to specifications.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that the filter did not perform as intended, e.G.Intended for the prevention of recurrent pulmonary embolism (pe) via placement in the vena cava.Cook will reopen its investigation if further information is received warranting supplementation in accordance with 21 c.F.R.803.56.This report includes information known at this time.A follow-up medwatch report will be submitted if additional relevant information become available.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, or that any cook device caused or contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
