[On technique of surgical treatment of extravasal stenosis of the celiac plexus].

Under analysis were the results of intraoperative observations during surgical treatment of 243 patients with extravasal stenosis of the celiac trunk. Special attention was given to anatomical correlation of the celiac trunk, celiac plexus, median arcuate ligament and median crura of the diaphragm involved in the compression of the celiac trunk. For the development and substantiation of optimal methods of decompression of the celiac trunk 106 anatomical preparations were investigated. The variants of the anterior diaphragm arteries and of the celiac trunk vessels were revealed whose injuries can result in intraoperative bleedings. Different variants of the operative technique depending on the anatomical conditions are proposed.
