Isolated renal vein and inferior vena cava thrombus following blunt trauma abdomen. A rare case scenario()

OBJECTIVE: Renal vein thrombosis in adults occurs as a result of various etiologies such as nephrotic syndrome, renal cell cancer, hypercoagulable state and trauma. Renovascular injury happens in 3% to 4% of patients with blunt abdominal trauma and usually occurs in association with significant injury to the abdominal viscera or skeleton. METHOD: A 40-year-old female suffered from blunt abdominal trauma following a road traffic accident while she was travelling as a pillion rider on a two-wheeler vehicle. RESULT: The patient was diagnosed with left renal vein and inferior vena cava thrombus without any associated renal parenchymal or injuries to other organs. She was managed conservatively with anticoagulants and regular monitoring. Follow up imaging after 3 months showed complete resolution of thrombus. CONCLUSION: Traumatic renal vein or inferior vena cava injury usually occurs in combination with renal arterial or parenchymal injury. Isolated major venous injury is rare.
