Pseudohyperkalaemia is an uncommon and frequently unrecognised biochemical abnormality. It occurs as a consequence of aggregation and lysis of platelets in vitro. As a result, potassium is released, which causes an elevated serum concentration. We present the case of a 21-year-old man with a traumatic splenic injury necessitating laparotomy and splenectomy. Following surgery he developed hyperkalaemia. Further investigations diagnosed pseudohyperkalaemia, one of the causes of which is thrombocytosis secondary to splenectomy.
假性高钾血症是一种罕见且常未被识别的生化异常。它是体外血小板聚集和溶解的结果。由此，钾被释放出来，导致血清浓度升高。我们报告一例21岁男性患者，因外伤性脾损伤而行剖腹探查术和脾切除术。术后他出现了高钾血症。进一步检查诊断为假性高钾血症，其原因之一是脾切除术后血小板增多症。
