A Novel More Effective Glue-Sealant (Arterx) for Hemostasis at Vascular Suture Lines and Other SitesWilliam M. Stone, MDMayo ClinicScottsdale, Arizona
ArterXArterial Surgery • Bleeding a natural consequence • Higher morbidity/operative time • Higher costs • Prosthetics most troublesome (ePTFE)
ArterXIncreasingly Problematic • Increased use of anticoagulants • Higher complexity of arterial reconstructions
ArterXMultiple Attempts to Assist with Hemostasis • Fibrin sealant • Cyanoacrylate • Bovine collagen and thrombin • Polyethylene glycol polymer • Albumin cross-linked with gluteraldehyde
Ideal Agent • High hemostatic and bonding properties • Minimal tissue reactivity • Non-antigenic • Biodegradable • Easy to sterilize • Conform to tissues
ArterX • Glutaraldehyde based • Treated cross-linking agent • Minimizes inflammatory response • Elastic biocompatible gel • Covalently bonds to tissues • Highly conformable
ArterXPhase I • Multi-institutional European trial • Open arterial reconstructions with prosthetic materials
ArterX • Primary endpoint-immediate hemostasis • Secondary endpoint-hemostasis at • 1, 3, 5 and 10 minutes • Additional hemostatic measures
ArterX • “Prophylactic” application • Sealant “sets” in 60 seconds • Flow restored and anastomosis observed
ArterXN=32 • 56 prosthetic graft anastomoses • Mean age 66 years (range 46-86) 26 (81%) male 6 (19%) female
ArterXN=56 Subclavian 1 (1.7%) Aorta 10/56 (18%) Carotid 2 (3.5%) Popliteal 4 (7.1%) Iliac 7 (12.5%) Brachial 4 (7.1%) Tibial 4 (7.1%)
ArterX • All anticoagulated • All given aspirin post procedure 19 (33%) ePTFE 38 (67%) Dacron
ArterX Immediate hemostasis in 56/56 100%
ArterX • Pivotal Trial • Randomized, prospective, controlled • United States, multicenter
ArterX • ArterX vs Gelfoam Plus (control) • Vascular reconstructions with prosthetic grafts • Applied prophylactically at completion of anastomosis
ArterX • 217 patients randomized • 331 anastomoses • ArterX group 110 patients • (167 anastomoses) • Control group 107 patients • (164 anastomoses)
ArterXN=110 • Mean age 66.2 years • No statistical difference in comorbidities including use of anticoagulants 69 (62%) male 41 (38%) female
ArterX • Primary endpoint • Immediate hemostasis • Secondary endpoints • Hemostasis at 1, 3, 5 and 10 minutes
ArterXImmediate Hemostasis • ArterX 101/167 (60.5%) • Control 65/164 (39.6%)
