Celiac artery stenosis may be caused by atherosclerotic degeneration or by compression exerted by the arched ligament of the diaphragm.
Celiac artery compression syndrome (angina abdominis) is abdominal or epigastric pain triggered by meals.
Symptoms may resolve after surgical resection of the arched ligament.
Improvements observed after surgery may be due to the concurrent destruction of the celiac ganglion rather than to the severance of the arched ligament.
Arterial flow in the celiac tract should be measured using continuous wave Doppler.
The signal should be measured during held inspiration because during expiration, an increase in the compression of the celiac tripod by the arched ligament may increase flow velocity.
