RESUMO
Objective To evaluate the result of staged arteriovenous shunts for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO). MethodsData of 176 cases undergoing this procedure were retrospectively reviewed. ResultsIn this group, 147 cases (83 5%) were followed up with a median of 9 8 years. Pain and/or claudication disappeared in 86 out of 90 cases (95 5%) treated by low positioned shunt one week postoperatively, with a limb salvage rate of 100%. Among 57 cases treated by high positioned shunts of the lower limbs, pain and claudication disappeared in 43 cases (75 4%) 2~3 weeks postoperatively. Postoperative amputation has to be performed in 5 cases with a limb salvation rate of 91%. ConclusionsThe clinical result of this staged arteriovenous shunts is satisfactory for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO).
