Hyperviscosity-related ischemic stroke in TOF with marked secondary erythrocytosis successfully managed with therapeutic phlebotomy

2026-08-03

Abstract excerpt

<title>Abstract</title> <p>Background Ischemic stroke is an uncommon but potentially devastating complication of cyanotic congenital heart disease [1,2]. Chronic hypoxia in Tetralogy of Fallot can result in secondary polycythemia and hyperviscosity, predisposing patients to thrombotic events [2,3]. The role of therapeutic phlebotomy in this setting remains controversial and is generally reserved for selected pat...
