Superior mesenteric artery branch – jejunal artery aneurysm☆

Abstract

Visceral artery aneurysm (VAA) is a relatively uncommon disorder and it shows some vague symptoms. Therefore, the clinical diagnosis is difficult and these aneurysms are discovered and diagnosed only after rupture in many cases. This case report describes the history of a woman who had a superior mesenteric artery (SMA) branch aneurysm. A 62-year-old woman presented with fatigue and moderate to severe epigastric and mid-back pain. A computed tomography of the abdomen and pelvis demonstrated a partially thrombosed aneurysm (38×40 mm) rising from the jejunal branch of the SMA. The aneurysm which contains mural thrombus is resected, and a saphenous vein graft interposition is performed between the ends of the same jejuno-jejunal artery. The patient's recovery was unremarkable, and she was discharged on postoperative day 7. Rapid diagnosis, localization, and surgical or endovascular interventions are necessary to avoid devastating consequences in VAAs. Saphenous vein graft interposition is a good choice for surgical intervention for patients not suitable for endovascular treatment.

Rupture of an Aneurysm of a Small Branch of the Superior Mesenteric Artery: A Case Report

“…Therefore, complications of this small aneurysm affect the treatment strategy. Kurdal et al also reported rupture of the aneurysm of the jejunal branch of the superior mesenteric artery, similar to our case [ 4 ]. The second branch of SMA that is likely to be the jejunal branch was involved in our case.…”

“…Various treatment procedures have been reported for the treatment of SMAA with intestinal ischemia or rupture. Surgery is usually performed, according to the recent studies [ 4 ]. Multiple surgical techniques have been described including ligation and bypass with autologous graft, thrombectomy and fixation of an intimal flap.…”

Ruptured ileocolic artery aneurysm: An unusual cause of hemoperitoneum

“…[34] The most common causes of aneurysm are atherosclerosis, angiodysplasias, arteritis and infection. [35] However, in our case, arteritis seems to be responsible because of raised leukocytes and C-reactive protein as well as mesenteric enhancement on the CT scan. These aneurysms are usually asymptomatic but rupture, thrombosis and distal embolization have been reported frequently.…”

“…These aneurysms are usually asymptomatic but rupture, thrombosis and distal embolization have been reported frequently. [3–5] These complications can be life threatening; as the incidence of spontaneous rupture reaches up to 50%. [6] Due to the presence of good collateral circulation these aneurysms are often amenable to ligation.…”

Ruptured jejunal artery aneurysm

“…Therefore, it is not uncommon that the aneurysm is only discovered after rupture, with hypovolaemic shock, leading to an increased mortality 9. The initial diagnosis in an emergent situation depends on the suspicion.…”
