COBBANA Trial

Comparison of Hemostatic effect and handling properties of Fibrillar collagen (Lyostypt®) versus Oxidized regenerated cellulose (Surgicel®) in suture hole bleeding of peripheral arterial bypass anastomosis using PTFE graft prosthesis.

Primary endpoint: Time to hemostasis.

Time to hemostasis using Lyostypt® was significantly faster compared to oxidized regenerated cellulose. Over 80% of cases suture hole bleeding stopped in less than 3 minutes using Lyostypt®, when using oxidized regenerated cellulose more then 80% of cases needed more than 5 minutes to achieve hemostasis.

Secondary endpoint: Intraoperative efficacy rating.

Lyostypt® show better adherence to bleeding site, in case repositioning was needed it was easy and possible in all cases. Only one fleece was necessary to control bleeding, showing the cost-effectiveness of Lysotypt®.
