Blood flow and diameter effect in the navigation process of magnetic nanocarriers inside the carotid artery
(2022)Background and objective: Serious side effects are occurred during the cancer therapy. Magnetic driving of nanoparticles is a novel method for the elimination of these effects by supplying with anticancer drug or increase ... -
Blood flow velocity comparison in the eye capillaries and postcapillary venules between normal pregnant and non-pregnant women
(2020)Background: There is no consensus on how much and at what diameters the blood flow velocity changes in the female microcirculation during normal pregnancy. Methods: A non-contact, digital slit-lamp biomicroscopy system was ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
A computational fluid dynamics modelling of maternal-fetal heat exchange and blood flow in the umbilical cord
(2020)Human fetal thermoregulation, maternal-fetal heat exchange, and the role of the umbilical cord in these processes are not well understood. Ethical and technical limitations have restricted current knowledge to animal ... -
COVID-19 hemodynamic and thrombotic effect on the eye microcirculation after hospitalization: A quantitative case-control study
(2022)BACKGROUND OBJECTIVE: To quantify the hemodynamic and thrombotic effect of COVID-19 on the eye microcirculation of patients with thromboprophylaxis, shortly after hospital discharge. METHODS: This case-control study included ... -
Echo-Doppler measurements of portal vein and hepatic artery in asymptomatic patients with hepatitis B virus and healthy adults
(2006)Background and aim. The aim of this prospective study was to determine the range of various hemodynamic parameters of portal vein and hepatic artery with echo-Doppler imaging in asymptomatic carriers of hepatitis B virus ... -
The effect of carotid revascularization on the ophthalmic artery flow: Systematic review and meta-analysis
(2021)Introduction: High-grade internal carotid stenosis results in impaired flow dynamics in the ocular circulation that may lead to a rare clinical entity; ophthalmic ischemic syndrome (OIS). The aim of this study was to ... -
Endograft Specific Haemodynamics After Endovascular Aneurysm Repair: Flow Characteristics of Four Stent Graft Systems
(2019)Objectives: The implication of haemodynamics in the occurrence of complications after endovascular aneurysm repair (EVAR) has been raised in the literature. Different aortic stent graft configurations may lead to different ... -
Haemodynamic performance of AFX and Nellix endografts: A computational fluid dynamics study
(2018)OBJECTIVES The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated ... -
Hemodynamic profile of two aortic endografts accounting for their postimplantation position
(2017)Endovascular aneurysm repair (EVAR) is a clinically effective technique for treating anatomically eligible abdominal aortic aneurysms (AAAs), involving the deployment of an endograft (EG) that is designed to prevent blood ... -
Influence of hemodialysis on the mean blood flow velocity in the middle cerebral artery
(2005)Background: Several effects of hemodialysis, including hemoconcentration, alterations of hemostasis or hemorheology and endothelial activation, could potentially interfere with cerebral blood flow (CBF) regulation. These ... -

Suture Line Response of End-to-Side Anastomosis: A Stress Concentration Methodology
(2015)End-to-side vascular anastomosis has a considerable complexity regarding the suturing of the juncture line between the artery and the graft. The present study proposes a stress–concentration methodology for the prediction ... -
The value of computed tomography perfusion & transcranial Doppler in early diagnosis of cerebral vasospasm in aneurysmal & traumatic subarachnoid hemorrhage
(2018)Early detection and diagnosis of cerebral vasospasm in subarachnoid hemorrhage may be challenging both on clinical and radiographic grounds. In this respect we conducted a pilot study in order to assess the feasibility of ...
