Celiac artery compression syndrome denotes the presence of external celiac artery compression and abdominal symptoms including abdominal pain, nausea and weight loss etc. Recently, we experienced one case of celiac artery compression syndrome comfirmed by abdominal arteriogram. A 29-year-old man presented with prolonged recurrent epigastric pain, nausea, vomiting and epigastric systolic brui for 8 years. On physical examination, laboratory studies and upper gastrointestinal studies with gastroduodenoscopy, ultrasonography and computerized tomography, there was no specific abnorma l finding related to symptoms of the patient. However, abdominal arteriogram revealed smooth narro wing of the celiac artery close to its origin with dominant splenic flow and arterial aneurysm abou 12mm in size at the gastroduodenal artery. We operated the patient with decompression method including division of the constricting median arcuate ligament and neural fibrous tissues surrounding the celiac artery. However, symptoms of the patient were not relieved. On the 9th day after the operation, transfemoral intraluminal angioplasty at the remaining compressed celiac artery was peformed. After the angioplasty, the symptoms of the patient were improved. (Kor J Gastroentero 1999;33:142 - 147)
