Coexistence of multiple anomalies in the celiac‐mesenteric arterial system

Abstract

The origins and distribution of arteries of the celiac-mesenteric system were examined by dissection of 52 formalin-fixed human cadavers. Seventy-five percent of the cadavers exhibited the classic Michels' Type I hepatolienogastric pattern; 25% had different branching patterns. Multiple anomalies of the celiac-mesenteric arterial system were observed in one Caucasian female cadaver: a short lienogastric trunk; a common hepatic artery arising directly from the abdominal aorta; an anomalous course of the hepatic arteries; an accessory left hepatic artery arising from the left and right gastric arterial anastomosis along the lesser curvature of the stomach; a double cystic artery; a common inferior phrenic trunk arising from the celiac trunk; and an aberrant arterial channel connecting the proximal segments of the splenic and gastroduodenal arteries. A patent ductus venosus and an anomalous formation of the portal vein by the confluence of the splenic and superior and inferior mesenteric veins was also observed. Although single anomalies of the celiac-mesenteric arterial system are common, complex combinations, such as were observed in the present case, represent a significant deviation from the normal developmental pattern. There seems to be no report in the literature of such a combination of anomalies coexisting in one individual. The developmental and clinical significance of these anomalous vessels is discussed.

Implication of the presence of a variant hepatic artery during the Whipple procedure

“…Its prevalence ranges from 25-45% (1)(2)(3)(4). The most frequent arterial variant is the aberrant right hepatic artery arising from the superior mesenteric artery (SMA) followed by aberrant left hepatic artery originated from the left gastric artery (1).…”

Variations in the Branching Pattern of the Celiac Trunk in a Kenyan Population

“…Knowledge of this variable anatomy may be useful in planning and executing radiological interventions such as celiacography (Glück et al, 1983) and chemoembolisation of hepatic tumors (Aigner & Gailhofer, 2005). Although the pattern of branching displays ethnic variations (Saeed et al, 2003), there is paucity of data on the branching pattern among Kenyans.…”

Pediatric Presentation of a Celiaco-mesenteric Trunk in Association with a Pelvic Bilateral Renal Ectopia: an Undescribed Association

“…Many anatomical variants have been reported by Lipshutz in 1917, who firstly described a celiacomesenteric trunk (CMT) [4]. Among variants of celiac trunk, the CMT is the least frequent with an incidence of 1-2.8% [6,7]. In literature, this vascular malformation is reported in association with other anomalies affecting the common hepatic, the left gastric and the splenic arteries [8,9].…”
