[Arterial thrombosis in the course of nephrotic syndrome. Report of three cases].

Vascular thrombosis remains severe complication in patients with nephrotic syndrome. Both venous and arterial thrombosis are observed. We report three new cases of arterial thrombosis in patients with nephrotic syndrome. The role of acquired hemostasis disorders, inducing hypercoagulability, is predominant. Extramembranous glomerulonephritis remains the most frequent cause of nephrotic syndrome, complicated by vascular thrombosis. Treatment is based on anticoagulation and corticosteroid therapy. Search for proteinuria should be part of the etiology work-up in all patients with vascular thrombosis of undetermined origin.
