Thrombosis (DVT), Pulmonary Embolism (PE).
Key Clinical Message : Congenital absence of Inferior
Vena cava is a rare anomaly . As the case for other congenital anomalies
, it should be suspected at all ages in any patient who presents with
recurrent complications of venous stagnation such as PE and recurrent
DVTs . Key Clinical findings are : recurrent DVT and/or PE , Stigmata of
Venous engorgement as a result of development/enlargement of collateral
veins . Background : Congenital absence of Inferior Vena Cava (
CAIVC ) is a rare anomaly in which the lower-body venous return is
impaired . There is usually engorgement of other veins especially Azygos
and Hemiazygos systems .Ethical Clearance : A full Informed consent was
taken from the patient . Permission was taken from the patient for
publication .Case summary : a 47 year-old man presented who was
successful treated for PE . Later discovered to have left sided venous
engorgement in the abdomen and left lower limb . He was later discovered
to have congenital absence of inferior vena cava and was prepared for
further investigations including venography and coagulation profile .
