Description of event according to initial reporter: a cook celect filter was then placed for our sheath.The sheath was then backed up to uncover the filter, and the filter was deployed under direct flouroscopic visualization.However,it would not release.Ultimately the filter was moved from the ivc into the right iliac vein, and due to the mal-deployment of the filter and the inability for it to release from the push rod of the cook celect delivery system, the decision was made to leave it in the right iliac vein.It should be noted that prior to this the patient became increasingly anxious and uncomfortable, and due to the patient's morbid obesity and concern for adequate airway control with increasing doses of conscious sedation, we elected to convert the case to general endotracheal anesthesia, and as such the anesthesia service intubated the patient while we paused to get this completed.Once this was done, we re-engaged into the procedure.The sheath in the groin was used to help disassemble the push shaft assembly of the cook celect device from the actual ivc filter, which was ultimately deployed in the distal external iliac vein.Thereafter a wire was readvanced up into the inferior vena cava, and the inner dilator of the sheath was used to allow the sheath to re-access the ivc.Power injection venography was then performed of the vena cava and iliac system, with findings and interpretation noted above.Intravascular ultrasound was reintroduced to evaluate the iliac and ivc to make sure that there was no evidence of injury to those structures after repositioning of the previous filter.Thereafter, a new cook celect ivc filter was placed, and this was placed in the correct position just below the renal vein confluence.Patient outcome: patient was awoken and extubated in the operating room and sent to recovery in stable condition.
