abdominal apoplexy

ab·dom·i·nal ap·o·plex·y

mesenteric hemorrhage, thrombosis, or embolus involving the mesenteric or abdominal blood vessels.

abdominal apoplexy

(1) A hoary term for intra- or retroperitoneal haemorrhage secondary to intestinal infarction or a ruptured aortic aneurysm, resulting in acute haemoperitoneum. Small amounts of blood in the peritoneum produce hyperosmolar irritation when RBCs lyse; when a visceral artery ruptures (splenic artery more often than hepatic) the irritation becomes clinically important, causing acute ‘peritonitis’, abdominal pain, decreased bowel sounds, increased WBCs.
(2) Mesenteric infarction (or other massive "event" affecting the vascular supply of the mesenteric vascular system).

abdominal apoplexy

Obstruction to the blood flow and bleeding into an abdominal organ, such as the INTESTINE, or bleeding into the PERITONEAL CAVITY.

Abdominal apoplexy, or idiopathic spontaneous intraperitoneal hemorrhage (ISIH), is rare and often fatal.
Traditionally, abdominal apoplexy refers to spontaneous hemorrhage arising from one of the smaller abdominal arteries or veins, after hemorrhage from a grossly apparent aortic aneurysm or aortic dissection is excluded.
In addition to the above disorders, rare cases of abdominal apoplexy have been attributed to arterial dissections involving splanchnic vessels such as the gastroduodenal, hepatic, superior mesenteric, gastric, and splenic arteries (1).
These two cases demonstrate the continued therapeutic and diagnostic challenges associated with the clinical management of patients with abdominal apoplexy.
Both cases also demonstrate our currently imperfect understanding of abdominal apoplexy, and further research is certainly required.

Abdominal apoplexy is an uncommon disorder, typically due to atheromatous vascular disease, inflammatory processes such as pancreatitis eroding into large blood vessels or vasculitis.
Abdominal apoplexy is an uncommon disorder most typically due to atheromatous disease.
The presentation of an elevated lipase in the setting of abdominal pain is not specific for pancreatitis and can be associated with abdominal apoplexy.
