Background. The aim of ­this ­study was to ­answer the ques­tion if the in ­situ tech­nique in infra­in­gui­nal arte­ri­al recon­struc­tion is bet­ter ­than the non ­reversed one in ­long-­term fol­low-up.
Methods. Patients ­were includ­ed in a pros­pec­tive ­study at oper­a­tion. 387 infra­in­gui­nal arte­ri­al recon­struc­tions in 367 ­patients per­formed ­from 10-88 to 12-98 ­were ret­ro­spec­tive­ly ana­lysed.
Results. 280 non-­reversed and 107 in ­situ ­bypass pro­ce­dures ­were per­formed. Primary paten­cy ­rates at 60 ­months ­were 63.3% for non-­reversed and 57.9% for in ­situ ­grafts (p=n.s.). Primary assist­ed paten­cy ­rates ­were 81.8% and 84.5% respec­tive­ly (p=n.s.). Limb sal­vage ­rate was not dif­fer­ent in ­either ­group. The 30-day mor­tal­ity was 1.9% in the in ­situ ­group and 0.7% in the non-­reversed ­group (p=n.s.).
Conclusions. There is no dif­fer­ence in out­come ­between in ­situ and non-­reversed ­vein graft­ing. Absence of sta­tis­ti­cal dif­fer­ence ­between the two pro­ce­dures may be main­ly due to the rou­tine use of angios­cop­ic qual­ity con­trol.
