Rupture of mesenteric artery branch aneurysm

Ruptured ileocolic artery aneurysm: an unusual cause of hemoperitoneum

Ruptured aneurysm of a branch of ileocolic artery is a rare finding and is an unusual cause of haemoperitoneum. Rapid diagnosis, and surgical or endovascular intervention are necessary to avoid devastating consequences and high mortality rates following an emergency operation after rupture. Resection is a good choice for surgical intervention for some aneurysms that are not suitable for endovascular repair. This report describes the case of a middle-aged man with a ruptured superior mesenteric artery branch aneurysm and his subsequent surgical management.

Spontaneous hemoperitoneum from a ruptured mesenteric branch arterial aneurysm: report of a case

We report a case of spontaneous intraperitoneal hemorrhage from a ruptured mesenteric branch artery aneurysm in a patient presenting with syncope. A 54-year-old woman was brought to our emergency department as a medical code, following two syncopal episodes. Computed tomography, carried out to rule out aortic aneurysmal disease, revealed hemoperitoneum without evidence of solid organ injury. Emergency exploratory laparotomy revealed a large jejunal mesenteric hematoma accompanying a ruptured mesenteric branch artery aneurysm with active extravasation. We ligated and excised the lesion and diagnosis was confirmed on final pathologic examination. We report this case because general surgeons should be aware of these vascular lesions and the basic guidelines for treatment.
