Background. Clear evi­dence of cere­bral ­blood cir­cu­la­tion ­has ­not ­been ­shown ­after axil­lo-axil­lary ­bypass sur­gery in ­patients ­with sub­cla­vian ­steal syn­drome.
Methods. We inves­ti­gat­ed ­the cere­bral cir­cu­la­tion ­and ­blood ­flow in 3 ­patients receiv­ing axil­lo-axil­lary ­bypass by RI angio­gra­phy ­using 99mTc-dl hex­a­meth­yl pro­py­lene ­amine ­oxime (99mTc-­HMPAO). Two ­patients ­had ver­te­bral bas­i­lar cere­bral symp­toms ­which ­were relat­ed to ­decreased cere­bral ­blood ­flow evi­denced by 99mTc-­HMPAO.
Results. After ­the cor­rec­tion, cere­bral symp­toms dis­ap­peared ­and ­improved cere­bral ­blood cir­cu­la­tion detect­ed by 99mTc-­HMPAO-­SPECT.
Conclusions. We con­clud­ed ­that axil­lo-axil­lary ­bypass ­was a fair­ly effec­tive pro­ce­dure to ­improve cere­bral ­blood cir­cu­la­tion evi­denced by 99mTc-­HMPAO-­SPECT.
