Case reportRupture of the spleen or splenic vessels (splenic emergency syndrome) in late pregnancy: A report of two autopsy cases
Introduction
Insidious spontaneous rupture of the spleen or splenic vessels in pregnancy is a rare event and the pathogenetic factors are still largely unknown. The event carries a high maternal and fetal mortality rate and the clinical picture has been named “splenic emergency syndrome”, terminology that well describes such cases [1], [2]. In fact, brisk intraperitoneal bleeding often causes an abrupt onset of shock, leading to sudden, unexpected death [3], [4]. These cases therefore come under the observation of the forensic pathologist because the precise cause of death can only be determined by autopsy [1], [5]. The forensic pathologist must evaluate any traumatic cause, even of a mild nature, especially in the context of familial violence. Quite often, medical negligence may be hypothesized, due to failure to diagnose or to inappropriate medical care [6]. We report two cases of death of young women in the third trimester of pregnancy, caused by rupture of an aneurysm of the splenic artery in one case and by splenic hemorrhage in the other. A review of the literature on similar cases emphasizes the morphological changes of the splenic arteries that may be correlated with these events [1], [3], [4], [5], [7], [8], [9].

Clinical summary
A 26-year-old woman, primigravida in the 40.5th week of pregnancy, suffered sudden malaise while at home, without loss of consciousness. Due to rapid, progressive deterioration of her condition, the patient was admitted to the local hospital two hours from the onset of the symptoms. She arrived in a state of hypovolemic shock. Intensive care procedures were performed, blood and plasma substitutes were transfused and ultrasound scans were urgently accomplished. No fetal movements were noted, but
Discussion
The cases we describe demonstrate classic “splenic emergency syndrome” occurring in the third trimester of pregnancy, during labor or postpartum. The events most frequently reported in literature giving rise to this dramatic picture are rupture of a splenic artery aneurysm (SAA) and, more rarely, cases of “spontaneous” rupture of the spleen.
Aneurysm of the splanchnic arteries is an uncommon form of vascular disease but has a considerable clinical importance owing to its tendency to rupture. SAA
