Abstract Inferior vena cava agenesis is a rare condition and is often misdiagnosed. This anomaly is asymptomatic in the majority of cases and is usually diagnosed during imaging tests carried out for other purposes. The most frequent manifestation is deep vein thrombosis (DVT) in lower limbs and anticoagulation therapy is the most frequent treatment option. https://www.roneverhart.com/2-1-2-x-1-4-x-36-Smooth-Saddle-Threshold-NGP-410-36/
