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.

An analysis of retrospective data has shown that 34 (14.4%) out of 236 patients with aneurysm of the abdominal aorta and iliac arteries and in 62 (5.1%) out of 1214 patients with occlusion or stenosis of these vessels mainly had cancer of the lungs (52%) and stomach (17.7%) with almost similar incidence in both groups. Colorectal cancer (8.3%) and cancer of other organs of the abdominal cavity were detected more rarely. Aneurysmatic (12 patients) and occlusive-stenosing (17 patients) lesions of the aorto-iliac segment were noted in 29 (0.4%) among 6834 patients with lung cancer or organs of the abdominal cavity. There were three subgroups of patients: (1) first cancer was diagnosed, and then aneurysm, stenosis or occlusion of these arteries (12-12.5%); (2) diseases of the arteries and cancer were diagnosed simultaneously (60-62.5%) and (3) first lesions of the arteries and later cancer (24-25%). Two-stage operative interventions for these diseases were made in 30 (31.2%) patients.

A prospective study included 106 patients with celiac trunk compression syndrome (CTCS). Duplex scanning of the celiac trunk and superior mesenteric artery and echocardiography were performed during their examination. The investigation revealed primary mitral valve prolapse (PMVP) in 78 (74%) patients. Operations of decompression of the celiac trunk were made on 101 patients. After operation the symptoms (neurovegetative included) were found to disappear. No authentic distinctions were revealed in the clinical semiology and postoperative course of patients with CTCS and with a combination of CTCS and PMVP.

Nineteen patients with chronic obstructive disease of the lungs and 15 patients with chronic non-obstructive bronchitis of the dust etiology were examined for the purpose of investigating the rheological blood properties and of their interrelation with pulmonary hypertension. The hemorheological properties were evaluated by spontaneous aggregation of erythrocytes and thrombocytes. The control group comprised 8 healthy subjects. The results denoted that the rheological blood properties are to a great extent impaired in patients with dust bronchitis. The rheological blood properties worsened as hypertension of the small blood-circulation circle was increasing; it preceded the development of pulmonary hypertension in patients with chronic obstructive disease of the lungs. The aggregation changes appear to be primarily related with the functional state of thrombocytes in patients with chronic non-obstructive bronchitis; a concurrently higher aggregation of thrombocytes and erythrocytes was observed in patients with chronic obstructive disease of the lungs. The obtained data can be useful for designing a medicamental correction scheme of rheological impairments as a trend within the treatment of affected hemodynamics in the small blood-circulation circle in patients with duct bronchitis.

To examine feasibility of usage of phase IV hemodynamic alterations in the course of Valsalva's test in patients with bronchial asthma for detection of latent insufficiency of the right heart and pulmonary hypertension, 24 patients with mild bronchial asthma and 8 healthy individuals were subjected to Doppler echocardiography. The results indicate that this method is simple, well tolerated, can assess functional reserves of the lesser circulation. It can be used both for primary diagnosis and follow-up.
