Abstract
OBJECTIVES:: BACKGROUND:: METHODS:: RESULTS:: Functional collateral perfusion was found in 40 of the 89 patients (45%). Angiographic signs of collaterals (Rentrop ≥ 1) were present in 15 of the 89 patients. Of the 40 patients with the functional collateral perfusion 11 patients (28%) had Rentrop ≥1; of the 49 patients without functional collaterals there were 4 patients with Rentrop ≥1 (8%) (P = 0.02). There were no significant differences in baseline clinical characteristics or in other angiographic characteristics. CONCLUSIONS
