Item Ultrasound features of the endometrium in women with abnormal uterine bleeding on the background of extragenital pathology(2023) Гаркавенко, Карина Володимирівна; Лазуренко, Вікторія Валентинівна; Абдуллаєв, Різван Ягубович; Васильєва, І.А.; Карпенко, Володимир Геннадійович; Пасієшвілі, Нана Мерабівна; Garkavenko, Karyna; Lazurenko, Viktoriia; Abdullaiev, Rizvan; Vasylieva, I.; Karpenko, Volodymyr; Pasiieshvili, N.The article presents the results of dopplerometry of the uterine vessels in 45 women aged 40-55 years with abnormal uterine bleeding (AUB) – in 25 of them against the background of the metabolic syndrome (MS), which made up the main group and in 20 without MS (comparative group). The control group consisted of 20 women with a normal menstrual cycle. All women with AUB underwent ultrasound of the uterus and appendages on the day of treatment, and women in the control group – on the 5-8th day of the menstrual cycle. Ultrasound in patients with AUB against the background of MS revealed a threefold increase in the thickness and 1.6 times in the volume of the endometrium compared with the control group (p<0.05). The presence of polypoid formations in the uterine cavity was detected in 7 (35%) patients with AUB, in 3 (15%) women with AUB against the background of MS. It was found that in women with AUB, compared with women in the control group, the indices of resistance (P<0.05) and pulsation (P<0.001) significantly decreased in the radial and basal arteries. In women with AUB against the background of MS, the thickness (P<0.05) and volume (P<0.001) of the endometrium significantly increased. The results of the study show that the metabolic syndrome is one of the factors in the development of endometrial hyperplasia, which is the cause of abnormal uterine bleeding. Doppler ultrasound in these women reveals a significant decrease in vascular resistance.Item Evaluation of hemodynamics in vertebral arteries in case of herniated cervical intervertebral discs using functional tests(2023) Абдуллаєв, Різван Ягубович; Вороньжев, Ігор Олександрович; Абдуллаєв, Руслан Різванович; Коломійченко, Юрій Анатолійович; Abdullaiev, Rizvan; Voronzhev, Igor; Abdullaiev, Ruslan; Kolomiichenko, YuriiBackground. Degenerative changes of the vertebral-motor segment occupy an important place among the causes of cervicogenic headache, neck pain with radiation to the shoulder and arm, noise in the head, dizziness. The same symptoms are often found in vertebral artery syndrome, which is a set of disorders of vertebral-basilar dynamics. Dopplerography makes it possible to obtain quantitative parameters of blood flow in the vertebral arteries, thereby assessing the level of pathological changes in blood flow. Purpose. Dopplerographic assessment of blood flow parameters in vertebral arteries in patients with herniated cervical intervertebral discs using functional tests. Materials and methods. An analysis of the results of dopplerography of the vertebral arteries in 42 young patients with herniated cervical intervertebral discs was carried out. Peak systolic velocity (Vs), end-diastolic velocity (Vd), indices of peripheral resistance (RI) and pulsatility (PI), minute volume of blood flow (HOK – Vvol) in the second segment of the VA at the C2-C3 level were determined at functional tests. Results. With a left-sided hernia, the value of Vs in the left VA during contralateral head rotation was 34.1 ± 2.9 cm/s, RI – 0.71 ± 0.03, PI – 1.04 ± 0.06, HOC – 85 ± 9 ml/min, and in the comparison group – 45.3 ± 3.8 cm/s, 0.59 ± 0.02, 0.85 ± 0.04, 118±13 ml/min, respectively. In patients with a right-sided hernia, Vs in the right VA during contralateral head rotation was 32.6 ± 3.2 cm/s, RI – 0.72 ± 0.03, PI – 1.03 ± 0.06, COC – 83 ± 8 ml/min, and in the comparison group – 44.8 ± 4.1 cm/s, 0.60 ± 0.02, 0.87 ± 0.04, 117 ± 12 ml/min, respectively. The difference between Doppler blood flow parameters obtained during contralateral head rotation in patients with disc herniation and the comparison group (persons without disc herniation) was significant (P < 0.05). Conclusion.Hemodynamically significant disruption of blood flow in the vertebral artery occurs when the paramedian and posterolateral hernia is localized on the side of the same name during head rotation to the opposite side. These violations consist in a significant decrease in systolic speed and minute volume of blood flow, in an increase in indices of resistance and pulsatility compared to persons without disc herniation.Item Characteristics of late post-infarction cardiac remodeling(2023) Abdullaiev, Rizvan; Kapustnyk, Valeriy; Markovskiy, Volodymyr; Kulikova, F.; Kyrychenko, A.; Tomakh, N.; Абдуллаєв, Різван Ягубович; Капустник, Валерій Андрійович; Марковський, Володимир Дмитрович; Кулікова, Ф.Й.; Кириченко, А.Г.; Томах, Н.В.The article presents the results of echocardiography in assessing cardiac remodeling in 79 patients 12 months after acute myocardial infarction (MI). 42 (53.2%) patients had Q-positive (Q+), 37(46.8%) Q-negative (Q-) myocardial infarction. After 12 months, chronic heart failure (ChHF) was detected in 32 patients, of which 23 (54.8%) as a result of Q(+), and 9 (24.3%) Q(-) infarction. In patients who underwent Q (+) MI with ChHF in the late post-infarction period, the values of left ventricular end-diastolic dimension (EDD), end-sistolic dimension (ESD), left atrial dimension (LAD), local contractility index (LCI), sphericity index (SI), left ventricular myocardial mass index (LV MMI, g/m2 ) were significantly (P<0.05, P<0.01) higher than in patients with Q ( -) MI and without ChHF. The average value of such EchoCG parameters as ejection fraction (EF, %), degree of shortening of the anteroposterior dimension of the left ventricle (ΔS, %) and the ratio of the total wall thickness and LV EDD (2H/D index) in patients with Q (-) MI was higher than in the group of patients with Q (+) and without ChHF.
