Abstract:
Objective Toexplorethepatencyofbridgevesselsinpatientsaftercoronaryarterytransplantation,andto providereferencefortheselectionofclinicalbridgevessels.Methods Dataof32patientsunderwentcoronaryangiography aftercoronaryarterybypassgraftingwereselectedandanalyzedretrospectively.Theoverallusageandpatencyofthegreat saphenousveingraft(SVG),theleftinternalmammaryartery(LIMA)andtheradialartery(RA)wereanalyzed.Thepatency ofthenearfuture(5years),themediumterm(5-10years)andlongterm(>10years)werecomparedbetweenthethreekinds ofbridgingvascularvessels.TheRAocclusionwasanalyzed. Results Thetotalnumberofbridgevesselsusedin 32 patientswas85,only1caseusedrightinternalmammaryartery(RIMA),theothersusedSVG,LIMAandRA,inwhich48, 23and13brancheswereusedrespectively.ThepatencyratesofSVG,LIMAandRAwere25%(12/48),73.91%(17/23)and 69.23(9/13)respectively.Therecentandmedium-termpatencyratesofallbridgevesselsshowedadecreasingtrend,in whichtherecentpatencyrateofSVGwassignificantlyhigherthanthatinLIMA,theintermediatepatencyratesofLIMAand SVGwerehigherthanthatofRA,andthelong-termpatencyrateofRAwassignificantlyhigherthanthatofLIMAandSVG.
