en General گزارش مورد case report <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong>Introduction:</strong> Knowledge of the unpaired abdominal vasculature is important for uncomplicated operations. The absent celiac trunk has previously been reported; however, developmental alterations can result in a variety of branching patterns of the downstream arteries from the abdominal aorta.<strong><br> Case Presentation: </strong>A 53-year-old female patient with lymphoma underwent abdominopelvic computed tomography (CT) for staging. She had a history of postprandial off-and-on abdominal pain since her youth. CT scan revealed an absent celiac trunk with common hepatic and splenic arteries directly originating from the abdominal aorta. Compression of the median arcuate ligament had narrowed and angulated the 2 branches.<br> <strong>Conclusions:</strong> When the celiac trunk is absent, its main branches may separately arise from the abdominal aorta. Also, due to the displacement of these branches, their path and diameter can vary from the normal.</span></span></div> Abdominal Aorta,Common Hepatic Artery,Trifurcation,Celiac Trunk 0 0 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-229&slc_lang=en&sid=1 Mersad Mehrnahad mersad.mehr@gmail.com 10031947532846005221 10031947532846005221 Yes Department of Radiology, Qom University of Medical Sciences, Qom, Iran Mohammad Hasanian 10031947532846005222 10031947532846005222 No Department of Radiology, Arak University of Medical Sciences, Arak, Iran Mohammad Mosahar Mehrnahad 10031947532846005223 10031947532846005223 No School of Medicine, Yazd University of Medical Sciences, Yazd , Iran
