With vascular compliance, the RI was dependent on vascular resistance and increased with increasing resistance. The higher the compliance, the more the RI was affected by resistance. gladiator brown suede caged sandalsWebA low RI should be investigated with an angiogram or surgical reexploration. An RI of greater than 0.9 is common in the early posttransplant period, due to increased hepatic artery resistance from allograft edema related to IR injury, and this should normalize in a few days as the edema resolves.
