Superior mesenteric artery syndrome in a patient with celiacomesenteric trunk

Abstract

Superior mesenteric artery (SMA) syndrome is an uncommon entity leading to compression of the duodenum between the aorta and the SMA. Normally the coeliac trunk and the superior mesenteric arteries have distinct origins from the abdominal aorta. The celiacomesenteric trunk (CMT) is the least frequently reported anatomic variation of all abdominal vascular anomalies. CMT denotes a common trunk of origin of the coeliac and superior mesenteric arteries. The coexistence of these anomalies has never been reported in the literature. We present a case of a 59-year-old man presenting with duodenal obstruction due to SMA syndrome with CMT. The aortomesenteric angle was 13 degrees and SMA-aorta distance was 8 mm. Patient underwent a gastrojejunostomy. After an uneventful recovery, the patient has been symptom free for 1-year follow-up.

Diagnostic and Surgical Implications of Non-occlusive Mesenteric Ischemic Ileus Associated With Common Celiacomesenteric Trunk: A Case Report and Literature Review

“…The SMA syndrome is a duodenal obstruction secondary to acute angulation of the SMA-compressing part of the small intestine [ 25 ]. A 15-year-old who presented with colicky abdominal pain and bilious emesis was found to have a CT finding of partial duodenal obstruction by an acute angulation of a CMT concerning the abdominal aorta.…”

Co-Existence of An Unusual Branching Pattern of Celiacomesenteric Trunk With Complete Common Mesentery in a 48-Year-Old Man: A Case Report

“…Anatomical variations involving a common origin of celiac trunk and SMA has first been described by Adachi (1928) and was named the celiacomesenteric trunk (CMT) (Ataka et al, 2021). The prevalence of this variation has been reported to range between 1% and 2% of all anomalies involving the celiac axis (Deshpande et al, 2021; Tur Martínez et al, 2020). Although, extremely rare, this variant is well defined and known (Bhatnagar et al, 2013).…”
