Pilot Study to Asses the Function and Patency of Polyester-Coated Composite Bypasses From Autologous Varicose Veins

PROVENA
Start date: June 2005
Phase: N/A
Study type: Interventional

If patients need to undergo bypass surgery, either an autologous vein can be used as bypass or, if there are no suitable veins are available, a prosthetic graft can be implanted. Varicose veins normally are judged not to be suitable as bypass. The ProVena vein support, made from polyester, is considered to strengthen varicose veins so that they they become suitable as bypass. Thereby, the advantages of an autologous bypass and the stability of polyester material can be combined. Patients that take part in the trial recieve an autologus bypass with a varicose vein, coated with ProVena. They are followed up at 3 and 6 months after implantation of a ProVena-coated bypass via duplex-sonography to assess the graft patency.
