title: [The hydrodynamic evaluation of some types of aortocoronary bypass].
abstract: Liquid flow in cylindrical and converging transplants for aortocoronary bypass, in intricately branching vascular systems were experimentally studied by polarization optic method using "jumping" aortocoronary shunts and different flow regimens, sites and severity of vascular stenosis. Hydrodynamic advantages of conic shunts in comparison with cylindrical ones were revealed, the rest shunting conditions being equal. It was found that when "jumping" shunts are used the distal portion of the coronary artery which is shunted the first should not be dilated by more than 50%. The end anastomosis should be formed with the artery more significant for myocardial blood supply.
