Lefevre, M. Hamon for the OCTOPLUS study group ICPS Massy, CHU “Cote de Nacre” Caen, La Roseraie Aubervilliers, CHU Henri Mondor Creteil, France, Brighton and Sussex UH Brighton, England
Aim of the study • This prospective multicentric randomized study was carried out to assess the potential advantages of Transradial (TRA) approach in Octogenarians for diagnostic and intervention procedures
Study Centers Participating centers: • ICPS, Institut hospitalier Jacques Cartier and Hopital Claude Galien, Massy and Quincy, France (Y. Louvard, C. Loubeyre, P. Garot, T. Lefevre, O. Tavolaro, P. Dumas) • CHU Cote de Nacre, Caen, France (M. Hamon, S. Rigattieri R. Sabatier, G. Grollier) • Hopital Europeen de Paris « La Roseraie », Aubervilliers, France (H. Benamer) • Brighton and Sussex University Hospital, Brighton, UK (D. Hildick-Smith)
Primary Endpoint Composite approach-related vascular complications leading to a discharge delay: Vascular surgery, any transfusion, Hb loss > 3g/ 100ml or Ht loss > 10%, acute leg or hand ischemia, false aneurysm, forearm compartment syndrome, other vascular complication leading to discharge delay
Secondary Endpoints Secondary endpoints: • Previously described approach-related vascular complicationsplus: hematoma > 3 cms in diameter, cholesterol embolism, TIA or stroke, radial artery occlusion • Coronary angiography and PTCA success rates, complications, procedural and X-Ray exposure times, contrast medium volume • Cost analysis: equipment use for diagnosis and intervention, complication related extra-costs (compression device, hospital stay, biological analysis, echo-doppler, transfusion, surgery…)
Inclusion / Exclusion criteria, Randomization • 377 Octogenarian patients randomized, after informed consent, to Radial or Femoral approach using a blinded allocation list for each center • Excepted: - double mammary coronary grafting - known occlusion of 2 femoral or arm arteries - previous approach failure • For coronary angiography and/or PCI, whatever the clinical presentation (including AMI) • Before: - femoral pulse evaluation - Hand blood supply evaluation
Statistics • Mean + SD • Percentage • Mean comparison with t-test • Percentage comparison with X² • Primer of biostatistics 3.01, Stanton A Glantz • Independent vascular complication predictive factors by multivariate logistic regression analysis

Predictors of vascular complications in octogenarians: multivariate analysis Twenty-eight data elements selected for analysis Predictors by univariate analysis: femoral approach (p<0.001) small size (p<0.005) female gender (p<0.009) thienopyridine treatment (p<0.09) thrombolysis within 24 hours (p<0.015). Predictors of the primary endpoint by multivariate analysis: femoral approach OR: 22.2 95% CI: 2.4-207.9 p=0.007 thrombolysis w/in 24 h OR: 19.5 95% CI: 2.2-172 p=0.007 patient height <158 cm* OR: 6.4 95% CI: 2.0-20.4 p=0.02 1st height quartile
Conclusion (1) • Combined end-point of all approach related vascular complications leading to prolonged hospital stay is significantly lower in Octogenarian randomized to Transradial approach for Coronary angiography and/or PCI compared to Transfemoral approach • Approach related vascular complications are more severe in Femoral randomized group and occur mainly in patients actually approached through Femoral artery (cross overs)
Conclusion (2) • Per-protocol analysis shows a higher occurrence rate of the combined end-point and significant blood loss in procedures performed through Femoral artery and a trend for a lower transfusion rate
Conclusion (3) • As in younger patients, for coronary angiography, in intention-to-treat analysis, procedural and X-Ray exposure times are slightly but significantly longer in the Transradial group without differences in contrast medium and equipment use • As in youger patients, for PCI, there is no difference in Procedural and X-Ray exposure times, contrast medium volume and equipment use
Conclusion (4) • Transradial approach is an effective way to reduce the rate of vascular complications related to coronary angiography and PCI in the high risk octogenarian population
