title: Femoral-femoral bypass. Non-invasive hemodynamic evaluation.
abstract: Seven patients who underwent femoral-femoral by pass between June 1980 and September 1982 underwent pre-operative angiography and pre and post-operative non-invasive evaluation to determine: (1) the hemodynamic effects created by the crossover graft, and (2) if angiographic findings would be predicative of post-operative results. The mean ankle/arm (a/a) index in the donor extremity changed from 0.82 +/- 0.20 to 0.70 +/- 0.27 (NS). The a/a index in the recipient extremity increased from 0.39 +/- 0.30 to 0.74 +/- (p less than 0.02). One patient developed a "steal" syndrome. There was no correlation between angiographic findings and post-operative changes. This study demonstrated a significant increase in recipient extremity ankle pressure and a clinically insignificant decrease in donor limb pressure.
