In animal experiments we have shown that there is a critical narrowing beyond which the pressure required to transmit low viscosity (saline) or high viscosity (motor oil) rises rapidly (Morel et al. 1990; Linares et al. 1992). We have postulated that the high pressure of perfusion could cause mocosal damage at the maximal part of narrowing.
