Rare Congenital Anomaly of the Inferior Vena Cava
Incidental finding during gynecological tumor surgery
A 56-year-old woman underwent explorative laparotomy at our center due to confirmed carcinosarcoma of the uterus. During surgery an anomaly of the inferior vena cava was seen. The right common iliac artery appeared to perforate the confluence of the iliac veins (Figure).
Anatomic anomalies of the inferior vena cava are rare congenital malformations, found in <1% of the population. They are usually discovered incidentally on imaging, vascular interventions, or retroperitoneal operations, or may be found in the event of acute thrombosis/embolism. Surgeons performing retroperitoneal interventions should be aware of the possibility of such anomalies. Referral to the vascular team is recommended, but specific treatment is usually required only if symptoms occur.
