Back­ground. Inter­est of blood flow and ankle bra­chi­al pres­sure index (ABPI) to eval­u­ate ­result of iliac angio­plas­ty.
Meth­ods. ABPI and blood flow rates were meas­ured ­before and after angio­plas­ty in 22 lower extrem­ities of 16 ­patients with iliac sten­o­sis. Blood flow rates were deter­mined by means of a nucle­ar mag­net­ic res­o­nance (NMR) flow ­me­ter.
­Results. The day after angio­plas­ty, flow and pres­sure were increas­ing sig­nif­i­cant­ly, where­as a month later, only blood flow was increas­ing sig­nif­i­cant­ly. In a group of ­patients with near-nor­mal ABPI ­before angio­plas­ty (ABPI ≥ 0.8), there was, on the day fol­low­ing the angio­plas­ty, a sig­nif­i­cant ­increase in ABPI and pul­sa­tile blood flow rates; flow rates ­increased con­sid­er­ably a month after the oper­a­tion where­as ABPI stay ­stable. In a group of ­patients with clear­ly abnor­mal ABPI ­before angio­plas­ty ( ABPI <0.80), there was a sig­nif­i­cant ­increase in ABPI and blood flow rates the day after angio­plas­ty and again a month later.
Con­clu­sions. Flow there­fore seems to vary inde­pen­dent­ly of pres­sure. The pos­sible use of flow meas­ure­ment to ­detect reste­nos­es is yet to be stud­ied.
