“…2 The reported incidence was .07%-8.7%, including IVC duplication, left-sided IVC, a-/hypo-plasia, webs, and mega cava. 3 Congenital absence of the IVC, also described as IVC agenesis or interruption at a certain segment (infrahepatic, infrarenal, or suprarenal), has an overall prevalence of .6% and higher (range 5%-9.5%) in patients with DVT. 4 Certain cases of IVC agenesis have been accompanied with other congenital abnormalities such as cardiovascular defect, situs viscerus inversus, polysplenia, asplenia, and others.…”

Venous Thromboembolism in a Patient with Interrupted Inferior Vena Cava and Compressed Azygos Continuation: A Case Report and Review of Literature

We report an unusual case of a 40-year-old male patient who experienced painful swelling of the left lower limb that persisted for 1 week. Imaging modalities not only confirmed the diagnosis of acute iliofemoral venous thrombosis and pulmonary embolism (PE), but also an incidental finding of interrupted inferior vena cava (IVC). This congenital anomaly is uncommon but rarely associated with venous thromboembolism (VTE). The azygos continuation was compressed by the descending aorta against the 11th thoracic vertebrae, which was identified as the cause of VTE. He was treated successfully with anticoagulation and compression therapy. The patient was discharged with lifelong oral Rivaroxaban and remained asymptomatic. In the literature, only 9 cases of interrupted IVC-associated PE were identified but none was due to significant venous compression.

Background: Duplicate inferior vena cava (IVC) is an uncommon congenital malformation, but should be treated carefully under the circumstances of deep venous thrombosis (DVT). However, there is a paucity of clinical guidance on this situation. Methods: Duplicate IVC was diagnosed based on the imaging examination that revealed the dual IVC. Deep venous thrombosis was diagnosed by Compression Doppler ultrasonography of both lower extremities with the high-elevated D-dimer. Retrievable IVC filters were implanted to prevent massive and fatal pulmonary embolism. Appropriate anticoagulation therapy was also performed. Results: Two retrievable filters were successfully implanted and retrieved in two patients with deep venous thrombosis and duplicate inferior vena cava, respectively. During further follow-up, no adverse event was reported. Conclusion: Comprehensive imaging examination might contribute to the diagnosis of duplicate IVC, especially when individual conditions were limited. The position above the confluence of bilateral IVCs might be an appropriate suprarenal retrievable filter insertion location. To deal with different types of dual IVC anatomy, different strategies should be taken into consideration.

“…Due to a complex embryogenesis process, congenital anomalies of the IVC and its tributaries are not uncommon, with a reported prevalence of 0.3% to 10.14% of the population and a total of 14 observed variations; knowledge of these clinical entities may avoid severe consequences during retroperitoneal surgical procedures (especially laparoscopic procedures) [ 16 , 17 ].…”

Inferior Vena Cava Ultrasonography for Volume Status Evaluation: An Intriguing Promise Never Fulfilled

The correct determination of volume status is a fundamental component of clinical evaluation as both hypovolaemia (with hypoperfusion) and hypervolaemia (with fluid overload) increase morbidity and mortality in critically ill patients. As inferior vena cava (IVC) accounts for two-thirds of systemic venous return, it has been proposed as a marker of volaemic status by indirect assessment of central venous pressure or fluid responsiveness. Although ultrasonographic evaluation of IVC is relatively easy to perform, correct interpretation of the results may not be that simple and multiple pitfalls hamper its wider application in the clinical setting. In the present review, the basic elements of the pathophysiology of IVC behaviour, potential applications and limitations of its evaluation are discussed.
