Aim. To evaluate thrombus characteristics in patients with atrial fibrillation (AF) taking different direct oral anticoagulants (DOACs) using Thrombodynamics test.Materials and methods. Thrombodynamics test was performed in 100 patients with paroxysmal and permanent forms of AF taking different DOACs, dose choice was done in accordance with the instructions for drugs use. For analysis samples of fresh citrated platelet-free plasma were taken just before regular DOACs dose intake (trough concentration). Statistical data processing was carried out using R software packages.Results. All patients had no history of thrombosis or bleeding before inclusion in this study. All parameters of Thrombodynamics test taken at residual concentration of DOACs were in general within reference values, that is in the area of normal coagulation: spatial clot growth rate (V) – 26.56 (25.0; 29.2) μm/min, the time to the start of clot growth (Tlag) – 1.05 (0.85; 1.27) min, initial spatial clot growth rate (Vi) – 44.3±7.7 μm/min, stationary spatial clot growth rate (Vst) – 26.5 (24.9; 28.4) μm/min, clot size (CS) – 999.7 (912.9; 1084.7) μm, clot density (D) – 22883.1±3199.9 arb. units. D was appeared to be higher in women [22947.7 (21477.5; 22947.7) vs men [22124.8 (19722.8; 22124.8), p=0.035] and Tlag was significantly higher in patients with chronic heart failure [1.2 (1.0; 1.2) vs 1.0 (0.8; 1.0), p=0.008]. A correlation was found between level of creatinine and Tlag parameter, glomerular filtration rate (GFR) and clot density. With an increase in the level of creatinine in the blood and a decrease in GFR, respectively, there was an increase in Tlag parameter (p-value 0.038); with an increase in GFR, clot density decrease (p-value 0.005).Conclusion. All parameters of Thrombodynamics test on residual concentration of DOACs were within reference values that indicated optimal anticoagulant effect of all DOACs. The obtained data of normal coagulation at the residual concentration of the anticoagulant are consistent with the previously obtained data on the safety and effectiveness of DOACs using other methods. Further studies with clinical end points are needed to assess the clinical value of this method.
BACKGROUND: The problem of cervical elongation is becoming increasingly important due to the rising prevalence of pelvic organ prolapse. In Russia, descent and prolapse of pelvic organs account for 39% of all gynecological pathologies. AIM: This study aimed to compare the immediate and long-term results of surgical treatment for cervical elongation in combination with vaginal wall prolapse in patients of three clinical groups. MATERIALS AND METHODS: A total of 105 patients aged 30 to 55 years with a combination of cervical elongation and vaginal wall prolapse of degrees III were followed up. The patients were divided into three clinical groups based on the implemented surgical techniques, including group 1 (n=36) with Moscow surgery, group 2 (n=35) with modification of the Manchester surgery using synthetic implants, and group 3 (n=34) with Manchester surgery. The patients underwent a comprehensive clinical examination, surgical treatment, and follow-up in the early and long-term postoperative periods (1, 6, 12, 24, and 36 months). The efficacy of surgical treatment was assessed using a questionnaire. During dynamic monitoring, a gynecological examination with a Valsalva maneuver, and transperineal, and transvaginal echography were performed. RESULTS: During the first month after the surgery, patients noted irregular dragging pains in the perineum and/or inguinal region every second. A frequent urge to urinate was reported in 16.7%, 17.1%, and 17.6% of patients in groups 1, 2, and 3, respectively. A further survey revealed that the surgical treatment results were satisfactory, as it had a positive effect on the quality of life and mood and contributed to an increase in social and sexual activity. According to the physical examination, there were no signs of prolapse recurrence and mesh-associated complications. Erosion of the anterior vaginal wall over the polypropylene endoprosthesis was detected 6 months after the surgery in 3 (8.6%) patients of group 2. Genital prolapse recurrence was diagnosed after 1236 months in 7 (20.6%) patients of group 3. After 36 months, degree I prolapse of the posterior (n=1) and anterior (n=1) walls of the vagina was revealed in patients of groups 1 and 2, respectively.
BACKGROUND: According to several Russian researchers, the number of cesarean deliveries in different regions of Russia varies from 15.2% to 42%. The incidence of complications inconsistency of the uterine scar (isthmocele) after surgery is 10%15%. AIM: This study aimed to assess the efficiency and safety of robot-assisted surgery in the correction of isthmoceles after cesarean section in patients of reproductive age. MATERIALS AND METHODS: The study involved seven patients aged 2734 years with signs of isthmoceles after urgent or elective cesarean section 12 months to 6 years prior to hospitalization. A comprehensive dynamic examination (echography, magnetic resonance imaging, and office hysteroscopy), surgical treatment with the da Vinci Si robotic complex, and outpatient monitoring in the early and long-term period (1, 6, 12, 24, and 36 months) were performed. RESULTS: The patients were satisfied with the results of surgical treatment during outpatient monitoring due to the improved quality of life resulting from the reduction of pathological symptoms. The control echography (1, 6, and 12 months later) showed normal myometrial thickness (911 mm) and adequate blood flow in the metroplasty area in all patients. The niche was not visualized during office hysteroscopy 6-months after the metroplasty. Three patients became pregnant 1620 months after the reconstructive uteroplasty and ended with a timely operative delivery. Two patients were followed up for their pregnancies at 12 and 29 weeks of gestation, while two women continued taking oral contraceptives and planned their next pregnancy at least a year later. CONCLUSIONS: The use of the da Vinci Si robotic system for surgical correction of isthmoceles provides volumetric three-dimensional visualization of anatomical structures, reduces the duration of surgery and intraoperative blood loss, minimizes the number of intraoperative and postoperative complications, and contributes to accelerated postoperative rehabilitation of patients.
