Spontaneous inferior vena cava thrombosis

Case contributed by Dr Chris O'Donnell


Pain and swelling in left leg for 3 days. Has Protein C and S deficiency, on long term Warfarin.

Patient Data

Age: 55
Gender: Male

Filling defect in common femoral and iliac veins with absent blood flow on duplex interrogation.


CT scan to determine extent of thrombosis and exclude a pelvic mass

Filling defect indicative of thrombus extends from the expanded left femoral and iliac veins into the IVC terminating just below the renal veins.  Note oedema in the pelvic fat due to venous congestion.

Case Discussion

In the absence of neoplasm, extension of leg vein thrombosis into the IVC is unusual, in most cases terminating at or below the iliac veins.
