In order to obtain representative results all consecutive treatment procedures had to be submitted by the participating trial centers.<h4>Material and methods</h4>This was a prospective, nonrandomized multicenter study design. All patients suffering from intermittent claudication (IC, Fontaine stage II) or critical limb ischemia (CLI, Fontaine stages III and IV) were included. Trial centers with less than 5 cases reported within the 3‑month trial period or centers that could not ensure the submission of all tGefasschirurgie : Zeitschrift fur vaskulare und endovaskulare Chirurgie : Organ der Deutschen und der Osterreichischen Gesellschaft fur Gefasschirurgie unter Mitarbeit der Schweizerischen Gesellschaft fur Gefasschirurgie17-27https://www.ebi.ac.uk/biostudies/studies/S-EPMC5306226biostudies-literaturePercutaneous endovascular treatment of infrainguinal PAOD: Results of the PSI register study in 74 German vascular centers.PMC5306226Dus ESNaundorf MKuffner HReimer PSixt SSchmidt GRumenapf GStorck MRemig JOssig UTigges WPClassen SGeier BNoppeney THeidemann FLange TThom KDHuberts UGhoi ROberhuber APetridis CLauff VKBaumhakel MBlajan EGunkel WOrend KHKrupski-Berdien GWenk MBalzer KMKiechle VBurger TWalter DNitschmann KHaustein KKindermann MDebus ESLesser TWenk HHammermuller TWilde JBreuer PEder SWeidenhagen RBanafsche RKuhnert MVoshage GHatzl JBrune UGrabedunkel JHoffmann JKleemann MPflugradt ATeßarek JSiggelkow MWeis-Muller BDahl PWiedner MHofmann MSchaefer TDelgado JPLiewald FSchelzig HJacobs MStautner EDill HRichter PLommel DKronert TGrundmann RTFahrenkemper TWagenbreth KDGahlen JGortz HBehrendt CAOckert DMFeidicker BBohner HWalluscheck KPSeifert SRiepe GSchofer JKrahl MCoster ASchneider MBarbera LKolka PQuellmalz UHader OPSI CollaboratorsBrunkwall JForkel JWittstock FTStehr ANoldeke STeebken OEfalsePercutaneous endovascular treatment of infrainguinal PAOD: Results of the PSI register study in 74 German vascular centers.<h4>Background</h4>The percutaneous infrainguinal stent (PSI) register study aimed to collate all percutaneous endovascular procedures for infrainguinal peripheral arterial occlusive disease (PAOD) conducted in 74 German vascular centers between September and November 2015 (3 months).
