      Prevalence of inferior vena cava anomalies and their significance and impact in clinical practice.
      The authors investigated the difference in prevalence of inferior vena cava (IVC) anomalies in patients diagnosed with deep venous thrombosis (DVT) vs. those who had computed tomography (CT) scans for diagnostic purposes, and a control group who had CT scans for health screening purposes. The study concluded that the occurrence of IVC anomalies was 1.8% in the control group and 6.3% in the DVT group. Duplication and left sided IVC were the most prevalent in the control group and hypoplasia was the predominant anomaly in the DVT group. Their recommendations focused on evaluating patients, especially young patients with iliofemoral DVTs, for IVC anomalies.
