Glomerulonephritis and nephrotic syndrome complicated by renal vein thrombosis and pulmonary emboli: report of two cases.

Two patients with membranous glomerulonephritis and nephrotic syndrome developed renal vein thrombosis and pulmonary emboli. Renal disease appears to be the initiating event in this syndrome complex. While intravenous urography and radionuclide venography are useful, inferior venacavography followed by pulmonary angiography are the definitive diagnostic procedures. Follow-up cavography is indicated to monitor progress of anticoagulant therapy in clot dissolution or recurrence.
