title: Celiac artery compression syndromes.
abstract: Compression of the visceral arteries can produce true mesenteric ischemia, but the syndrome is rare. The syndrome is caused by unfavorable anatomic relationships at the aortic hiatus among the CA, the SMA, and overlying structures, particularly the diaphragmatic crura. These anatomic relationships, in contrast to the syndrome they sometimes produce, are relatively common, which makes the detection of CA compression only a prerequisite to the diagnosis of the clinical entity. The diagnosis of CA compression syndrome ultimately depends on the relentless elimination of other possible causes for abdominal pain and on the knowledge that this curious syndrome does indeed exist. If properly diagnosed, the CA compression syndrome can be corrected with a safe, relatively simple surgical procedure. Past treatment series reflect too little appreciation for the extensiveness of a true, chronic CA injury. Revascularization of the CA, in addition to release of compression, should therefore be performed with greater frequency in the future. The young patients who are successfully diagnosed and treated for this unusual syndrome are frequently entirely relieved of long-standing, debilitating pain, and, like other patients with chronic mesenteric ischemia, they typically enjoy dramatic improvement in the quality of their lives. Thus, with the prospect of these patients in mind, a clinician should accept the opinion that the syndrome "does not exist" only after careful consideration of the entire literature.
