Abstract Ensuring the transport of oxygenated blood to the brain is one of the priorities of the human body. In the literature, there are many models of cerebral circulation with different levels of complexity used to assess pathological conditions,

Arterial walls are a multilayer structures with nonlinear material characteristics. Furthermore, residual stresses exist in unloaded state (zero-pressure condition) and they affect arterial behavior. To investigate these phenomena a number of theoret

Most of the existing models of cardiovascular system do not take into account the leakage of blood through a number of small vessels branching the main arterial trunks and called perforators. Therefore, the aim of this study is to investigate their i

We comment on the paper by Juniewicz et al (2005 Physiol. Meas. 26 1039–48) which addresses problems in application of the Marmarou model for analyzing intracranial pressure changes during and after the infusion test, as well as the clinical releva

According to international guidelines, patients with Peripheral Artery Disease (PAD) are burdened with high cardiovascular risk. One of the simplest, non-invasive methods for PAD detection is the ankle-brachial index (ABI) measurement. The ABI is cal

The aim of this study is to highlight properties of an ankle-brachial index (ABI) using a specially designed numerical simulator of pulse wave. The ABI test is used by many practitioners to detect some vascular diseases. The 19-elements, linerised 1D

Background and Purpose— Intracranial bleeding is linked to hemodynamic stress factors, such as hypertension. However, there are no studies that tested the breaking pressure of normal large cerebral arteries in humans. Methods— The brains of 10 ca

The aim of this paper is to investigate the role of residual stresses in cerebral arteries, particularly in the Common Carotid Artery (CCA). Numerical simulations were based on experimental data described in the literature. Finite Element Method (FEM

Although flows of fluids in curved channels belong to a classical problem of fluid dynamics, most publications are restricted to investigations of flows in tube coils, or in single bends. This paper presents experimental and numerical (CFD) results c

The main goal of the present study is to examine compensatory parameters of intracranial space in giant hydrocephalus. We also assess the early and late outcome and analyse complications in shunted cases.Nine cases of giant hydrocephalus characterise
