摘要
Dunbar syndrome or celiac artery compression syndrome is an infrequently described clinical condition with poorly defined diagnostic criteria and an obscure pathophysiology. It is usually associated with an extrinsic compression upon the celiac axis near its takeoff from the aorta by fibrous diaphragmatic bands or sympathetic neural fibers. The authors report the case of a 70-year-old male patient presenting with nausea, epigastric pain, and weight loss. An aortography showed a compression of the celiac trunk. A preliminary attempt at percutaneous transluminal angioplasty and stenting proved unsuccessful. The patient became asymptomatic and his clinical condition improved after surgical release of the celiac trunk by partial section of the arcuate ligament of the diaphragm and with resection of the neural, fibrotic, and lymphatic tissues surrounding the aortic and visceral vessels. The purpose of this report is to discuss the indications and the therapeutic options of this syndrome. A s赤ndrome de Dunbar ou compress o do tronco cel赤aco 谷 uma condi o cl赤nica infrequente, com poucos crit谷rios para diagn車stico e com patofisiologia obscura. Est芍 usualmente associada 角 compress o extr赤nseca do tronco cel赤aco por banda fibrosas do diafragma e fibras neurais simp芍ticas, pr車ximo a sua emerg那ncia da aorta. Os autores relatam um caso de um paciente de 70 anos de idade com quadro de n芍useas, dor epig芍strica e perda de peso. Uma arteriografia mostrou compress o do tronco cel赤aco. Uma primeira tentativa de angioplastia com stent foi realizada em outro servi o, mas sem sucesso. Ap車s o tratamento cir迆rgico que consistiu de sec o parcial do ligamento arqueado do diafragma com ressec o dos tecidos fibr車ticos, neurais e linf芍ticos que circundavam a aorta e as art谷rias viscerais, o paciente obteve melhora cl赤nica e tornou-se assintom芍tico. O objetivo deste estudo 谷 discutir as indica es e op es terap那uticas desta s赤ndrome.
