The use of an original device developed by the authors which was introduced in the blood flow in experiments in dogs has confirmed the presence of coiled blood flow in different parts of the aorta. The rate, direction and angle of coiling were calculated. The results obtained suggest that the fact of coiling the blood flow should be taken into account when constructing new models of artificial valves of the heart in order to decrease the energy value of the cardiac output, to prevent injury of the formed elements of blood and thrombogenesis.

Acute internal carotid artery occlusion (AICAO) can result in malignant cerebral edema and unfavorable patient outcomes. This study evaluated the utility of transcranial Doppler (TCD) in assessing contralateral flow compensation and predicting outcomes in patients with AICAO. We enrolled 51 patients within 6 h of symptom onset and conducted TCD examinations to evaluate collateral circulation.

To assess the utility of IVIM parameters in evaluating uterine fibroid blood flow compared to dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) derived blood flow. Sixteen premenopausal women with uterine fibroids were enrolled in this prospective study. Pelvic MRI scans were obtained for each subject, both with and without continuous intravenous infusion of oxytocin, known to decrease significantly uterine fibroid blood flow, to assess the changes in blood flow of uterine fibroids.

Objective: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest.
Methods: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Objective: To investigate the association between functional parameters of the microcirculation and the systemic cardiovascular system in a population of pregnant women at risk for gestational hypertension disorders.
Study Design: For this observational study, women at high cardiovascular risk according to maternal anthropometrics, obstetric and medical history, were recruited at random gestational age depending on time of referral to the outpatient clinic for high risk prenatal care at Ziekenhuis Oost Limburg, Genk Belgium. After birth, data of maternal and neonatal outcome were obtained from the hospital records: only women with normal pregnancy (n = 142) and with preeclampsia (n = 34) were included in this analysis.
