Background and pur­pose. Extension of indi­ca­tions for fem­o­rof­e­mo­ral cross­over ­bypass to ­patients ­with occlu­sive ­lesions of the ­donor ­iliac ­axis suit­able for PTA.
Methods. We eval­u­at­ed 10 ­patients under­go­ing fem­o­rof­e­mo­ral cross­over ­bypass ­after PTA of the ­donor ­iliac ­artery ­between March 1988 and March 1999: 3 at ­stage 2B ­with dis­abling claud­i­ca­tion; 3 ­with rest­ing ­pain; 4 ­with troph­ic ­lesions. The ­mean age of ­patients was 67 ­years. All ­patients under­went ultra­so­nog­ra­phy and dig­i­tal arter­i­og­ra­phy (DSA). Extra-ana­tom­ic revas­cu­lar­iza­tion was sug­gest­ed in 9 ­patients who pre­sent­ed a gen­er­al­ly ­high sur­gi­cal ­risk, and in 1 ­patient ­owing to ­local tech­ni­cal dif­fi­cul­ties. The ­mean ­ankle/arm pres­sure ­index was 0.72 in the ­donor ­limb (min 0.65-max 0.81) and 0.29 (min 0.23-max 0.42) in the recip­i­ent ­limb. Eight ste­nos­es of the com­mon ­iliac ­artery (80%) and 2 (20%) of the exter­nal ­artery ­were treat­ed ­using PTA; an endo­lu­mi­nal ­stent was posi­tioned in 8 cas­es. Mean fol­low-up: 56 ­months.
Results. No imme­di­ate com­pli­ca­tion was report­ed ­after endo­vas­cu­lar treat­ment; the ­mean ­ankle/arm pres­sure ­index of the ­donor ­iliac ­axis ­rose to 0.88 ­after PTA and to 0.54 in the recip­i­ent ­limb ­after ­bypass. Walking dis­tance ­improved in 3 cas­es, and rest­ing ­pain dis­ap­peared in 2 ­patients; troph­ic ­lesions ­healed in ­three ­patients. Two (20%) ­major ampu­ta­tions ­were ­required at 18 and 22 ­months in dia­bet­ic ­patients.
Conclusions. Femorofemoral cross­over ­bypass rep­re­sents a val­id alter­na­tive in ­high-­risk ­patients. By increas­ing ­inflow, PTA of the ­donor ­iliac ­axis guar­an­tees ­graft paten­cy and ­good leg per­fu­sion.
