The objective of this study was to determine if admission abdominal/pelvic CT on trauma patients can be used as a novel method to evaluate the inferior vena cava (IVC) anatomy and facilitate potential IVC filter placement. Consecutive trauma admission CT's were reviewed. The potential landing zone for filters was determined by the IVC mid portion between the renal and iliac veins. The IVC landmarks were described anatomically using the thoracic and lumbar vertebral bodies as reference points. The IVC diameter and anatomic anomalies which would affect filter placement were also evaluated from the CT. The records of 610 Trauma patients were reviewed. There were 518 (84.9%) that had an admission CT, forming the basis of the study. The CT for 500 of 518 (96.5%) was of sufficient quality to accurately evaluate the IVC. The third lumbar location of the IVC was a safe landing zone in 476 of 500 (95.2%). Anatomic anomalies were present in 47 of 500 (9.4%). We had the following three conclusions. The admission CT in over 96% of trauma patients can be used to determine the IVC filter landing zone. The third lumbar region of the IVC was a safe landing zone in over 95%. Anatomical anomalies affecting IVC filter placement were revealed in 9.4%.

The Successful Removal of Two Retrievable Inferior Vena Cava (IVC) Filters after 67 Days in a Patient with a Double IVC

et al. 2017

View full text Add to dashboard Cite

We herein present a case in which two retrievable inferior vena cava (IVC) filters, which were implanted to treat deep-vein thrombosis caused by the compression of a double IVC, were successfully removed on the 67th day after placement. The filters were individually placed in both the left and right IVCs. With a prevalence of only 0.2%, a double IVC is an extremely rare anatomical variation. The long-term effects of IVC filters are unknown, and the placement of a filter potentially introduces the risk of complications. Thus, if the patient’s clinical condition allows, the endovascular retrieval of the filter should be considered within a few months after implantation.

“…A missed duplicated IVC during filter placement may still allow for the development of a pulmonary embolus through the left cava. 2 An understanding of the normal embryology of the IVC can aid in recognizing the multiple anatomic variations. The IVC normally develops from a confluence of the three paired embryonic veins, namely the posterior cardinal, the subcardinal and the supracardinal veins.…”

“…Patients may present with pulmonary emboli despite previous placement of an IVC filter. 2 Anatomic variations may be identified at the time of venogram or visualized incidentally on CT. 10 It is important to identify these anomalies to prevent mistreatment of lower extremity DVT and to allow successful placement of caval filters. In addition, a duplicated IVC can present a challenge during aortic surgery secondary to an unexpected encounter during dissection of the infrarenal portion of the aorta.…”

An interesting anatomic variant of inferior vena cava duplication: case report and review of the literature

et al. 2013

View full text Add to dashboard Cite

Congenital anomalies of the inferior vena cava (IVC) occur in roughly 4% of the population. We report an interesting case of an atypical variant of duplicated IVC. A 20-year-old man presented with orthopedic injuries and intracranial hemorrhage following a motorcycle accident. He was taken to the fluoroscopy suite for IVC filter placement; duplication of the IVC was noted. The right and left iliac veins shared a normal confluence but two IVCs drained independently into renal veins before reuniting into a single structure. Both IVC filters were placed via a single puncture in the groin. We performed a search of the PubMed database using‘ inferior vena cava duplication’ and reviewed common anomalies of the IVC. Several variants of duplicated IVC exist; the most common of which is two distinct IVCs that arise from each iliac vein without a normal confluence. Our patient had a unique anomaly which allowed filter placements from a single puncture.
