Inferior mesenteric artery aneurysm revealed by massif rectal bleeding, case report

Abstract

Introduction Inferior mesenteric aneurysms are rare, usually asymptomatic. Their diagnostic is challenging based on clinical examination, ultrasonography, and abdominal CT scan; surgery remains the gold standard of treatment. Case report In this paper, we will report a clinical case of 62 years old man admitted to the emergency department for massif rectal bleeding due to inferior mesenteric aneurysm fistulization in the transversal colon one month after a left colectomy; the treatment was surgical consisted of a Ligation. Conclusion IMA aneurysm is a rare condition, usually asymptomatic, and it might be revealed by various symptoms, including massif rectal bleeding.

Endovascular management of colic artery pseudoaneurysm: A case report of successful intervention in a 59-year-old male with abdominal hematoma

“…The etiology of IMAPs can range from disease states, inflammation, infection, trauma, or iatrogenic injury [3] . Atherosclerosis, and similar causes of vessel wall degeneration, have been noted to be the most common causes of VAPAs [3 , 8 , 10] . Vasculitides such as Takayasu's disease, polyarteritis nodosa, and Behcet's disease have also been reported as possible causes [9 , 10] .…”

Vasculitides such as Takayasu's disease, polyarteritis nodosa, and Behcet's disease have also been reported as possible causes [9 , 10] . The direct cause of IMAP in our patient is unknown but may be due, in part, to atherosclerosis from a history of hyperlipidemia or perhaps due to any trauma that occurred from the patient's previous exploratory laparotomy.…”

“…The direct cause of IMAP in our patient is unknown but may be due, in part, to atherosclerosis from a history of hyperlipidemia or perhaps due to any trauma that occurred from the patient's previous exploratory laparotomy. Diagnosis of VAPAs can be made using abdominal ultrasound, however, contrast-enhanced CT angiography may provide the best visualization of morphology [8] , [9] , [10] . Between 20% and 50% of IMAP can present as ruptures [9] .…”

“… 18 , 20 , 21 , 22 Massive gastrointestinal bleeding secondary to bowel fistulization has also been reported. 23 , 24 The mortality associated with symptomatic IMA aneurysms is unknown given the rarity of these aneurysms and because most reports do not describe prolonged follow-up.…”
