Overview
Renal vein thrombosis (RVT) is the formation of a clot or thrombus obstructing the renal vein.
Pathophysiology
A hypercoagulable state or mechanical compression of the renal vein is often present in those patients with renal vein thrombosis. This can be due to malignancy or it can be due to the nephrotic syndrome. In nephrotic syndrome there is an excessive urinary protein loss which is in turn associated with decreased antithrombin III. It is unclear why the renal vein is susceptible to thrombosis in patients with nephrotic syndrome.
Causes
Common Causes
- Nephritic syndrome (defined as >3 g/d protein loss in the urine
- Hypoalbuminemia
- Hypercholesterolemia
- Edema
Uncommon Causes
- Antiphospholipid antibody syndrome
- Behçet's syndrome
- Hypercoagulable states
- Kidney transplant
- Renal cell carcinoma [1] [2]
Epidemiology and Demographics
Among patients with nephrotic syndrome, the incidence of real vein thrombosis is quite variable. Some reports place the incidence at 5% while others place it at 62%.
Diagnosis
Symptoms
Back or flank pain may be present. Hematuria may be present.
Imaging
CT Scan
CT angiography can be used in diagnosis.[3]
Treatment
Surgery to remove the clot is possible, but rarely performed.
Anticoagulation therapy can have some benefits.[4]
