Renal Vein Thrombosis Treatment & Management

Medical Care
- Treatment of nephrotic syndrome: Measures may include steroids and immune-suppression therapy. Treatment of underlying renal cell cancer includes surgery for early-stage disease.
- Symptomatic treatment includes diuretics and angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) to decrease proteinuria from nephrotic syndrome. If a combination of ACEIs and ARBs lowers protein excretion more than either alone, they should be used together. Decreasing protein loss in the urine decreases hypercoagulability.
- Anticoagulation with warfarin has been recommended in some studies for prophylaxis against pulmonary embolism. Treat hypercholesterolemia according to accepted national guidelines (ie, using appropriate low-density lipoprotein targets for primary or secondary prevention).
- A recent study by Bianchi suggests that atorvastatin decreases the rate of progression of kidney disease, proteinuria, and hypercholesterolemia.[7]
Surgical Care
- Surgical treatment for renal vein thrombosis (RVT) is rarely used today.
- Surgery may be necessary for renal vein thrombosis (RVT) of renal cell cancer, particularly for cure of malignancy.
- Hypernephroma or renal cell cancer is unique in that intraluminal tumor extends into the renal vein and inferior vena cava (IVC) and sometimes extends into the right atrium. In such cases, radical nephrectomy and removal of the tumor from the IVC and right atrium affords the chance of cure. This is not distant metastasis; rather, this is tumor extension within the renal vein and IVC.
Consultations
- Consult a nephrologist and interventional radiologist (only when medical therapy does not prevent pulmonary emboli).
- A surgeon (urologist) can assist in the staging and potential surgery for renal cell carcinoma (early-stage disease).
- A combined team that consists of a urologist, vascular surgeon, cardiac surgeon, transplant surgeon, or a combination thereof works together in complex cases of renal cancer with extension into renal vein, IVC, and right atrium.
Diet
- Many nephrologists recommend normal protein intake for patients with nephrotic syndrome.
- Protein restriction may be used with benefit in patients who are nephrotic who do not spill massive amounts of protein (approximately 10 g or more over 24 h) or in those who have chronic renal failure.[10]
