Renal Vein Thrombosis: Follow-up
Updated: Sep 17, 2009
Follow-up
Further Inpatient Care
Further inpatient care is as needed for loss of renal function or for the treatment of pulmonary emboli.
Further Outpatient Care
Further outpatient care is as needed for loss of renal function or for the treatment of pulmonary emboli.
Inpatient & Outpatient Medications
- For nephrotic syndrome, see the Medical Care section. The primary abnormality in nephrotic syndrome is excessive urinary protein loss. Urinary protein is injurious to the renal tubules.
- For pulmonary emboli, see the Medical Care section.
- ACEIs and ARBs decrease urine protein through an effect on efferent arteriolar pressure. Titrate to as high a dose as tolerated. If protein loss decreases, hypercoagulability improves.
- Atorvastatin
- Cyclosporine has demonstrated benefit in early trials for treatment of membranous nephropathy. A cure of the underlying nephropathy reverses nephrotic syndrome and renal vein thrombosis (RVT).
Transfer
For thrombolytics or interventional radiology, transfer patients especially if a vena caval filter is necessary in the event of failure of medical therapy for recurrent thromboembolism. The vena cava filter in these cases has to be placed above the level of renal veins (suprarenal IVC filter). This is unique because, in all other forms of DVT and pulmonary embolism, IVC filters are placed in the infrarenal segment of the IVC. Either the interventional radiologist or the vascular surgeon can perform this.
Complications
- Recurrent thromboembolic phenomena
- Renal failure
- Metastasis from renal cell cancer
- Problems specific to etiologic cause (eg, graft failure after renal transplantation)
Prognosis
- Prognosis of any glomerular disease may be worsened by superimposition of acute renal vein thrombosis (RVT), but whether the slow development of chronic renal vein thrombosis (RVT) accelerates renal functional loss is uncertain.
- The negative prognosis of renal vein thrombosis (RVT) is related to pulmonary embolic events. If renal vein thrombosis (RVT) is secondary to cancer, it may signal dissemination of the malignancy.
- Graft survival after transplantation is adversely affected by renal vein thrombosis (RVT).
Miscellaneous
Medicolegal Pitfalls
- Missing renal vein thrombosis (RVT) as the source for pulmonary emboli is a medical/legal pitfall.
- When a patient presents with pulmonary embolism (PE) and no evidence of lower extremity deep vein thrombosis (DVT), the patient should be examined for renal vein thrombosis and renal cancer. Renal cell cancer (hypernephroma) is unique in that it may cause PE by 2 mechanisms. The first is an increased secretion of erythropoietin, which increases blood viscosity and hypercoagulability, causing DVT and PE. The other mechanism is tumor extension into the renal vein and IVC (tumor thrombus), which may break loose and cause PE.
- Avoid use of warfarin (Coumadin) for renal vein thrombosis (RVT) during pregnancy. Heparin should be used instead.
