Five cases of acute adenohypophysial necrosis were detected among 33 patients who underwent major cardiac operation and died within 10 days. This finding indicates an increased incidence of pituitary necrosis in heart surgery patients compared with unselected autopsy material. Histologically, the lesions which closely resemble those associated most frequently with obstetric shock, elevated intracranial pressure and diabetes mellitus, are coagulative infarcts, due to suppression of adenohypophysial blood flow. The cause of circulatory arrest to the adenohypophysis remains obscure.
在33例接受心脏大手术并于10天内死亡的患者中，检测到5例急性腺垂体坏死。这一发现表明，与未经筛选的尸检材料相比，心脏手术患者垂体坏死的发生率有所增加。从组织学上看，这些病变与产科休克、颅内压升高和糖尿病最常相关的病变极为相似，是由于腺垂体血流受抑制而导致的凝固性梗死。腺垂体循环停止的原因尚不清楚。
