Celiac artery compression syndrome was first described in 1965. Dunbar introduced the first surgically treated serial. There were several hypothesis about this syndrome. One of them is the proximal localization of the celiac artery, the other one is external compression of anatomically normal celiac artery by median arcuate ligament. A 36-years old female patient with a body mass index of 1.63 with episodes of postprandial abdominal pain, vomiting, nausea and with a weight loss of 6 kg. in the last year was presented. In the light of this datas, CT angiography was performed. CT results confirmed the diagnosis of Dunbar's syndrome. Laparascopic MAL division was performed to this patient by general surgery with an assisting cardiovascular surgeon.The patient was ambulated in the 8. postoperative hour and started oral feeding. The patient did not develop any clinical complications and was discharged from hospital on the 3rd postoperative day. Control CT angiography was performed at the 9th day follow up visit. Comparison of preoperative and postoperative CT angiography results revealed a significant calibration increase in the celiac trunk and it’s branches.Multislice CT angiography should be performed when establishing diagnosis due to the advantages of 3D imaging at MAL syndrome. After the diagnosis, best results and short postoperative process can be achieved in experienced laparoscopic surgery centers by cutting median arcuate ligament and removing tissue surrounding the celiac artery. We believe that the presence of a cardiovascular surgeon in the operation may be useful for repairing possible vascuar injuries.
