При нарушении геометрии наблюдаются некоторые потери давления, определяемые типом и выраженностью патологии, а также местом ее расположения относительно точки бифуркации.</p></abstract><trans-abstract xml:lang="en"><p>By means of mathematical modeling of pressure losses in the internal carotid artery at the point of bifurcation of the common carotid artery it is established that in the absence of the violation of the geometry of the above arteries, pressure losses practically do not occur.
