Model of saccular aneurysm of the bifurcation node of the artery

Modified Kirchhoff conditions in the simple one-dimensional model of the branching artery developed by the authors, allow to describe an anomaly of its bifurcation node, congenital or acquired due to trauma or disease of the vessel wall. The pathology of the blood flow through the damaged node and the methods of determining the aneurysm parameters from data measured at the peripheral parts of the circulatory system by solving inverse problems are discussed.
