Congenital absence of inferior vena cava

Ablación por radiofrecuencia de vía anómala en paciente con agenesia de la vena cava inferior

“…Las anormalidades congénitas de la VCI en particular, se estiman en 0,5% de la población, aunque posiblemente sea superior, dado el hecho de que este es un hallazgo en muchos casos incidental, al realizar estudios o procedimientos por otras causas, ya que puede pasar asintomática durante toda la vida 4,5 .…”

Most researchers believe that the vast majority of cases of IVC interruption are due to congenital anomalies [3,8], either a lack of development of venous channels or lack of persistence of anastomotic channels.…”

Mechanical and pharmacologic catheter-directed thrombolysis treatment of severe, symptomatic, bilateral deep vein thrombosis with congenital absence of the inferior vena cava
