Interruption of the inferior vena cava and azygos continuation in a child with partial atrioventricular septal defect.

Congenital pathologies of the inferior vena cava are uncommon. Isolated congenital interruption of the inferior vena cava with azygos vein continuation could be considered part of the group of venous return anomalies. The major significance of this anomaly is its association with complex cardiac defects and the associated technical difficulties at the time of cardiac catheterization and abdominal surgery or interventional procedures. In our case, we describe a common atrium and partial atrioventricular septal defect in an 8-year-old girl with infrahepatic interruption of the inferior vena cava and azygos continuation without polysplenia. Magnetic resonance angiography and computed tomography, together with a clinical awareness of this pathology, can be used to diagnose this entity.

Iatrogenic vascular injury during to lumbar disc surgery.

We report two patients who sustained vascular injury while undergoing intervertebral disc surgery at the lumbar four and five level. Each patient suffered from massive bleeding and shock, urgent laparatomy was performed, and the vascular injuries were successfully primarily repaired. The experience prompted us to review reports in the literature since 1965 of vascular complications associated with surgical excision of hernia disc via a posterior approach. From our analysis, we highlight the clinical features and management, emphasising that rapid diagnosis and immediate intervention can result in a favourable outcome, as in our patients.
