Inferior Vena Cava Thrombus Secondary to Ureteropelvic Junction Obstruction with Severe Hydronephrosis.

BACKGROUND

Benign external compression of the Inferior Vena Cava (IVC) with distal thrombus formation is seldomly described in the medical literature.

CASE PRESENTATIONS: We report a case of external IVC compression by a dilated right renal pelvis and hydronephrotic kidney secondary to longstanding Ureteropelvic Junction (UPJ) obstruction found in a 68-year-old male. Management included therapeutic anticoagulation, IVC filter placement, attempted thrombectomy by interventional radiology, and interval repeats imaging. This patient demonstrated complete resolution of the caval thrombus on repeat imaging 2 months following discharge. This case highlights the importance of interdisciplinary team coordination, a crucial component of patient's management and eventual treatment plan. It is reasonable to manage patients with IVC thrombus with anticoagulation alone.

CONCLUSION

In the modern era, angiointerventional techniques provide minimally invasive approaches to the management of vascular disorders and minimize morbidity.
