ABSTRACT
The preoperative transabdominal ultrasonics duplex scanning (UDS) of celiac artery was made in quiet breathing, in inspiration, in expiration, using vertical position in 180 patients. As well as the intra-abdominal UDS was made before the decompression of the celiac artery using the pulmonary ventilation during narcosis and relaxation. Peak systolic blood velocity, degree of stenosis, arterial pressure gradient in the celiac artery and volume blood velocity were hemodynamically significant in quiet breathing, in expiration and intraoperatively, reliably lower in inspiration in vertical position. It is important to use respiratory and orthostatic tests in diagnostics of compressive stenosis of the celiac artery. The data, which were obtained in quiet breathing using vertical position, should be taken into account in order to distinguish the compressive stenosis from atherosclerotic stenosis or other origin.

The authors have performed an analysis of main indicators of celiac duplex scanning in 180 patients with celiac compression syndrome before operation, during decompression and at the postoperative period. All the patients underwent surgical celiac trunk decompression. The indicators of the intraoperative celiac duplex scanning (stenosis degree, linear peak systolic circulation rate) of the celiac trunk shower hemodynamic reliable stenosis and were sufficiently different from preoperative findings. The stenosis degree and linear peak systolic circulation rate were less during intraoperative examination than before the operation. Intraoperative, duplex canning allowed compressive stenosis of the seliac trunk to be differentatied in some patients from intravasal one (atherosclerosis and arteritis), and its adequate decompression to be performed. When performing the celiac trunk decompression it is thought to be necessary to fulfill its intraoperative ultrasound duplex scanning before and after elimination of the compression.
