Aim. The aim of this paper is to ­assess the fea­sibil­ity and effi­ca­cy of ­fibrin in induc­ing neo­vas­cu­lar­iza­tion as an angio­gen­ic sub­stance and/or car­ri­er for vas­cu­lar endo­the­lial ­growth fac­tor (VEGF) in ­patients with limb ische­mia.
Meth­ods. Twen­ty-three ­patients with limb ische­mia and ­referred for below the knee ampu­ta­tions were ran­dom­ized for treat­ment: group 1, 7 ­patients ­received only a ­saline injec­tion; group 2, 9 ­received intra­mus­cu­lar injec­tion of ­fibrin and group 3, 7 ­received the ­fibrin com­po­si­tion with defe­rox­a­mine and added VEGF165. The ­fibrin mesh­work was intro­duced into the pop­li­teal area of the dis­eased limbs using a dual ­syringe ­system (1 con­tained throm­bin solu­tion [1 mg, 5000 U] and 1 con­tained fibrino­gen [1 mg, Bax­ter ­Hyland Immu­no] solu­tion). In group 3, Defe­rox­a­mine (100 µg) and 500 µg of VEGF165 were added to the fibrino­gen solu­tion.
­Results. In the con­trol group 5 ­patients had under­gone below the knee ampu­ta­tion at the 3-6 month fol­low-up. Only 1 ­patient from Group 2 had below the knee ampu­ta­tion 5 ­months fol­low­ing ­Fibrin only admin­is­tra­tion. Clin­i­cal improve­ment was noted in all 8 ­patients fol­low­ing ­fibrin admin­is­tra­tion and in all 7 ­patients inject­ed with the ­fibrin mesh­work, defe­rox­a­mine and VEGF com­bi­na­tion.
Con­clu­sion. IM injec­tion of ­fibrin is safe and ­appears to be an effi­cient meth­od to treat limb ische­mia. These find­ings indi­cate that use of ­fibrin may be a novel and sim­ple meth­od for induc­ing ther­a­peu­tic angio­gen­e­sis.
