Ultrasonic Doppler Flowmetry

The aim: Of work is to determine changes in blood flow in the vessels of the anterior abdominal wall that occur after plastic surgeries in order to improve the results of operations and to develop new methods for the prevention of complications. Materials and methods: The study was conducted in 132 patients. Patients were divided into 2 groups: main group 64 and control group 68 patients. Main group has patients who underwent abdominoplasty in combination with liposuction; control group has patients who underwent abdominoplasty without liposuction. In both groups we make different simultaneous operations. Laser Doppler Flowmetry and Ultrasonic Doppler Flowmetry were performed to determine the blood flow indices in the flaps. Results: Liposuction volumes averaged 3.57 ± 0.74 liters of lipoaspirate. In the main group there were totaly 4 complications, in the control group complications developed in 9 patients. Comparing daily indicators between the two groups, no statistically significant difference in the dynamics of MI changes was found during the entire study period (p = 0.767). Increase in caliber of vessels, on average, from 1.55 ± 0.8 mm in the preoperative period to 1.68 ± 0.75 mm on the 14th day of the postoperative period was statistically significant (p < 0.05). Conclusions: The combination of abdominoplasty with liposuction and simultaneous operations does not lead to greater development of complications and allows to achieve good aesthetic results.

Doppler Flowmetry

Background: Prostanoids are used in the treatment of Raynaud’s phenomenon and acral perfusion disorders secondary to collagenosis. In subjective terms, intravenous administration of these agents produces success in more than 50% of patients. The therapeutic outcome of clinical administration of alprostadil or iloprost may vary from individual to individual. Patients and methods: The following variables were analysed in a cross-over study in 27 patients with collagenosis and Raynaud’s phenomenon: plasma viscosity and erythrocyte aggregation (rheological variables), partial pressure of oxygen and laser Doppler flowmetry in the finger region, and lymphocyte phenotyping and interleukin (IL) determinations (immunological variables). Results: Laser Doppler flowmetry revealed significant differences between patients with secondary Raynaud’s phenomenon and a control group of 25 healthy subjects. Laser Doppler readings did not change significantly as a result of the treatments. Therapy with iloprost produced a reduction in IL-1beta, L-selectin (CD 62 L) and IL-6. Conclusion: The change in immunological variables due to iloprost may explain the long-term effects of prostaglandins in the treatment of Raynaud’s phenomenon. From our results it is not possible to infer any preference for iloprost or alprostadil.

Abstract. Coronary artery disease (CAD) is the leading cause of morbidity and mortality in the industrialized countries. Assessment of symptomatic patients with suspected obstructive CAD is a common reason for a clinical visit. Noninvasive anatomical and functional imaging are established tools to rule-in and rule-out CAD, to assess the severity of disease and to determine the potential risk of future cardiovascular events. In this review, we discuss the updated Guidelines from the European Society of Cardiology on Chronic Coronary Syndromes and explore the different imaging modalities used in current clinical practice for the noninvasive assessment of CAD. The pros and cons of each method, especially comparing anatomical and functional testing, are presented. Furthermore we we address the practical clinical aspects in the selection of the optimal noninvasive tests according to clinical need.
