[The significance of respiratory and orthostatic tests in duplex scanning in diagnostics of celiac artery compression syndrome].

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.

[Intraoperative ultrasound duplex scanning in the diagnosis and assessment of results of surgical treatment of patients with celiac compression syndrome].

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.
