Reconstructive surgery for a fusiform common celiomesenteric trunk aneurysm and coexistent abdominal aortic aneurysm: Report of a case

Abstract

A celiomesenteric trunk (CMT) accounts for fewer than 1% of all visceral artery anomalies. Aneurysms involving a CMT are exceptionally rare: our search of the literature found only eight cases reported. We treated a 73-year-old man with both a fusiform CMT aneurysm and an abdominal aortic aneurysm (AAA). The celiac artery and superior mesenteric artery were reconstructed by performing a retrograde prosthetic-graft bypass originating from the right limb of the bifurcated aortic graft used to repair the AAA. To our knowledge, this is the first report of successful surgical treatment of a CMT aneurysm and coexistent AAA.

Successful treatment of a visceral artery aneurysm with a celiacomesenteric trunk: Report of a case

“…If the ventral longitudinal anastomosis persists, variations in celiac and mesenteric anatomy can occur, and a celiacomesenteric trunk may develop. [1][2][3] In our case the left gastric artery was not detected, but splenic and common hepatic arteries arose from a celiacomesenteric trunk, which was classifi ed as either type I or III of the four branching patterns in the celiacomesenteric trunk according to Higashi et al (Fig. 1B).…”

“…When the anastomosis does not form at all, a celiacomesenteric trunk develops. [1][2][3] Celiacomesenteric anomalies are rare, and account for less than 1% of all abnormal abdominal visceral arteries. 4 Visceral artery aneurysms are also rare, with an incidence of just 0.01%-0.2% in routine autopsies.…”

Celiomesenteric trunk with concurrent aneurysm: Report of a case

“…Ten cases, including the current case, have been reported in the English literature. [1][2][3][4][5][6][7][8] This report is the fi rst of a perfect evaluation of such an aneurysm using MDCT angiography. Abdominal visceral artery aneurysms can be caused by medial degeneration, trauma, surgery, infl ammation, infection, arteritis, collagen vascular disease, fi bromuscular dysplasia, or congenital anomalies.…”

“…Only a few cases have previously been reported. [1][2][3][4][5][6][7][8] This report presents the case of an aneurysm accompanied by a celiomesenteric anomaly as seen on 64-row multidetector computed tomography (MDCT) angiography in a patient with a medical history of hypoglycemia, hunger, and palpitation, without abdominal pain or discomfort. Reconstructed images obtained on MDCT with CT angiography are illustrated with correlative digital subtraction angiographic images.…”

A rare case of segmental arterial mediolysis

“…In the reparative phase, the medial defects in the lesion are repaired, filled with granulation tissues and finally fibrous tissue replaces the injured sites [4]. The process of injury and repair results in arterial wall lesions that can lead to dissection, aneurysm formation, stenosis or hemorrhage caused by rupture of the artery [3,5].…”
