Overview

Renal vein thrombosis (RVT) is the formation of a clot or thrombus obstructing the renal vein.

Classification

Acute Chronic

Unilateral bilateral

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

  • Malignancy
  • Nephrotic syndrome
  • Trauma (kidney biopsy)
  • Oral contraceptive pills
  • Hypovolemia
  • Inherited coagulopathy

Uncommon Causes

Epidemiology and Demographics

Prevalence of renal vein thrombosis in nephrotic syndrome is 5 to 60% [3] .Membranous nephropathy is responsible for 20 to 60 % of the cases which makes it the most common cause of renal vain thrombosis. Other etiologies like minimal change disease, membranoproliferative glomerulonephritis, and focal segmental glomerulosclerosis cause 10 to 50 % of the cases.

Diagnosis

Symptoms

Back or flank pain may be present. Hematuria may be present.

Imaging

CT Scan

CT angiography can be used in diagnosis.[4]

Treatment

Surgery to remove the clot is possible, but rarely performed.

Anticoagulation therapy can have some benefits.[5]
