A 23-year-old Saudi female presented with nephrotic syndrome. On renal
biopsy she had primary focal and segmental glomerulosclerosis which w
as resistant to steroids. Two years later she presented with absent le
ft arm pulses and on investigation a diagnosis of left ventricular thr
ombosis and thromboembolism of left brachial artery was made, Low anti
thrombin III, high fibrinogen levels and diuretic therapy were the pos
sible causative factors for hypercoagulable state. On anticoagulation
therapy initiated with heparin and continued with warfarin for 8 weeks
there was complete dissolution of intraventricular and improvement of
left brachial artery thrombosis. An early diagnosis and treatment of
this potentially serious complication of nephrotic syndrome are stress
ed.
