Case Report: Hepatomesenteric Trunk

Abstract

The coeliac trunk and the superior mesenteric artery are the two ventral branches which are arising from abdominal aorta and supply blood to wide area at the supracolic compartment. An abdominal vascular variation of a 65 years old patient who is diagnosed with acute aortic dissection was encountered. While evaluating the anatomic structures on the angiographies, we observed that the branching pattern of the coeliac trunk was not presenting trifurcation nature and the common hepatic artery was arising from the superior mesenteric artery. This report of branching variation which was presented with its anatomic aspects may help clinician while planning and performing some invasive surgical or radiological procedures.

Öz

Truncus coeliacusve arteria mesenterica superior abdominal aortun, suprakolik kompartımanda geniş bir alanı kanlandıran, iki ventral dalıdır. Akut aort diseksiyonu teşhisi alan 65 yaşındaki bir hastada bu abdominal damarlarda varyasyona rastlandı. Anjiografide anatomik yapıların değerlendirilmesi esnasında truncus coeliacus’un trifurkasyon yapısını sergilemediği, arteria hepatica propria’nın arteria mesentericasuperior’dan çıktığı gözlendi. Truncus coeliacus’un anatomik yönü açısından, bu dallanma varyasyonu, klinisyenlere bazı girişimsel cerrahi veya radyolojik prosedürlerin planlanmasında ve uygulanmasında yardımcı olabilir.
