The serum fraction of platelet-rich fibrin (hyperacute serum) has been shown to improve cartilage cell proliferation in in vitro osteoarthritic knee joint models. We hypothesize that hyperacute serum may be a potential regenerative therapeutic for osteoarthritic knees. In this study, the cytokine milieu at the synovial fluid of osteoarthritic knee joints exposed to hyperacute serum intraarticular injections was investigated.

It has been demonstrated that hyperacute serum is the most proliferative among plasma products, so we investigated how the cytokine milieu of osteoarthritic knee joint reacts to hyperacute serum treatment in vitro. Cartilage, subchondral bone, and synovial membrane explanted from osteoarthritic knees were stimulated by interleukin-1 beta (IL-1β) and the concentration of 39 biomarkers was measured in the co-culture supernatant after hyperacute serum treatment.

Stent fractures in the IA have not been assessed in larger cohorts. In this retrospective study, we examined the frequency and risk factors of IA stent fractures.

Authors present the diagnostics, treatment and follow-up of two patients as examples from their largest series in the literature. A 74-year-old male patient with a history of hyperlipidemia, hypertension, nicotine abuse and lower limb claudication was admitted because of acute upper limb claudication and dizziness.

Methods: A total of 147 patients (153 stenoses, 6 recurrent) (71 female; 121 left) with significant diameter stenosis (>70% in symptomatic, n = 46; >85% in asymptomatic, n = 101 patients) of pCCA treated between 1994 and 2006 were retrospectively reviewed. With the exception of one, all procedures were performed using a transfemoral approach.
