This also induces changes in flow leading to its failure. By this work the sites
which are prone to such changes are localized. The bypass models are developed
from transparent silicon rubber of elastic properties similar to arterial
tissues. Flow visualization is carried out by photoelasticity technique by using
dilute solution of vanadium pentoxide. This analysis carried out under pulsatile
flow conditions shows that the proximal stenotic region continues to contribute
to the alteration in flow in the hood region of the bypass. Thus making its
proximal and distal regions prone to flow-induced changes, which may lead to
its blockage over the long duration.</span
