[Clinical and morphological comparisons in extravasal stenosis of the celiac trunk].

The results of clinico-morphological examinations of 155 patients (of them 118 operated on) with extravasal stenosis of the celiac trunk due to the squeezing of the celiac plexus by the median arcuate ligament, cruses of the diaphragm, and neurofibrous tissue are presented. All the patients had the symptoms typical of "abdominal angina". The tissues taking part in the squeezing of the celiac trunk: the sympathetic ganglion (27 patients), nerve trunks (66 patients), and the surrounding connective tissue (48 patients) were all characterized by inflammatory and sclerotic alterations. Alterations in the form of manifestations of the peptic and duodenal ulcer were found in 18.7% of the patients and various variants of chronic gastritis in 95.4%. Morphological investigations of the liver condition (78 patients) revealed changes in this organ (increased content of lipofuscin, sclerosis, protein and fatty dystrophy, infiltration). The clinical manifestations and morphological alterations are caused by the blood flow disturbance in the celiac trunk due to its stenosis.
