“…These acute splenic sequestration events are associated with a rapidly enlarging spleen and result in anaemia, thrombocytopenia, and occasionally hypovolemic shock ( Aquino, Norvell & Buchanan, 1997; Geola, Kukreja & Schade, 1978; Orringer et al , 1991 ; Michel, Hernandez & Buchanan, 1992). Splenic infarction results from occlusion of splenic vessels; it can occur spontaneously or after a precipitating event such as exposure to high altitude ( Aquino, Norvell & Buchanan, 1997; Orringer et al , 1991 ; Sears & Udden, 1985). Clinical characteristics of splenic infarction include sudden onset of mild to moderate splenic enlargement, left upper quadrant pain, and wedge‐shaped defects on liver spleen scan ( Aquino, Norvell & Buchanan, 1997; Orringer et al , 1991 ).…”
