Back­ground. Cereb­ro­vas­cular dis­ease and cer­vical ­artery dis­eases are poten­tially treat­able con­di­tions ­that are asso­ciated ­with an ­increased inci­dence of ­stroke ­after car­diac sur­gery. ­This pros­pec­tive ­study was ­designed to deter­mine the prev­a­lence of cereb­ro­vas­cular dis­eases in the ­high ­risk pop­u­la­tion of cereb­ro­vas­cular ­event ­including ­some ­young ­patients in ­Japan and estab­lish the ­strategy for car­diac sur­gery of ­patients ­with cereb­ro­vas­cular dis­ease.
­Methods. 100 (71 ­male, 29 ­female) of 126 con­sec­u­tive ­patients under­going car­diac sur­gery ­under car­di­o­pul­mo­nary ­bypass ­were ­screened for the pres­ence of cereb­ro­vas­cular dis­ease by ­intra-arte­rial angio­gram.
­Results. In ­seven ­patients angio­graphic eval­u­a­tion dis­closed ­some evi­dence of cereb­ro­vas­cular dis­ease for 50% or ­greater sten­osis or cere­bral aneu­rysm. Pre­op­er­a­tive 99mTc-Hex­a­methyl pro­py­lene ­amino ­oxime (99mTc-­HMPAO) ­single emis­sion com­puted tomog­raphy (­SPECT) ­with com­bi­na­tion of bal­loon arte­rial occlu­sion ­test pro­vided ­detailed infor­ma­tion of cere­bral ­ischemic tol­er­ance and reli­able deci­sion ­making for sur­gical ­repair of cereb­ro­vas­cular dis­ease. No ­deaths ­were ­recorded and a ­small ­stroke in one ­patient.
Con­clu­sions. We con­cluded ­that cereb­ro­vas­cular ­screening in ­patients ­with car­di­o­vas­cular dis­ease may be ­requested in a ­high ­risk pop­u­la­tion of cereb­ro­vas­cular ­events.
