This multicenter, prospective KODRA registry subgroup analysis evaluated whether obesity influences DRA outcomes, including cannulation performance and DRA-related complications. Methods: 4,638 patients planned for palpation-guided distal radial artery puncture were grouped by BMI. Obese patients (BMI ≥25 kg/m2; n=2,205) were compared with non-obese patients (n=2,433). Results: Distal radial cannulation success was similar between groups, with no significant differences in crossover rate or DRA complications. Cannulation time was longer in the obese group. Conclusions: Obesity was not associated with success rate, crossover, or DRA complications in this analysis; only cannulation time differed.",{"@graph":69,"@context":114},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/impact-of-obesity-on-palpation-guided-distal-radial-access-for-coronary-procedures-subgroup-analysis-of-the-multicenter-prospective-kodra-registry/457900/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/impact-of-obesity-on-palpation-guided-distal-radial-access-for-coronary-procedures-subgroup-analysis-of-the-multicenter-prospective-kodra-registry/457900.png","ImageObject",300,407,{"name":92,"@type":93},"dabgoudw","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-09-30",true,{"@type":102,"interactionType":103,"userInteractionCount":44},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108],{"name":109,"@type":110,"acceptedAnswer":111},"What
