Delayed Death Due to Saddle Pulmonary Thromboembolus in Child With Nephrotic Syndrome Induced by Focal Segmental Glomerulosclerosis.

While the characteristic features of nephrotic syndrome (ie, proteinuria, hypoalbuminemia, peripheral edema, and hyperlipidemia) are well known, the association of nephrotic syndrome and the risk of thromboembolic events is not as often appreciated and may be overlooked. This report describes a 10-year-old boy with focal segmental glomerulosclerosis who died following a saddle pulmonary thromboembolus, with near-complete occlusion of the left and right pulmonary arteries. The gross appearance of the thrombus suggested organization and histologic changes within the wall of the pulmonary artery indicated a period of at least 3 or more hours to a few days since the event occurred.
