The "edge effect" after implantation of beta-emitting (55Co) stents with high initial activity.
Acta Medica (Hradec Kralove)
June 2004
The aim of this study was to evaluate the incidence and the cause of "edge restenosis" after implantation of high activity 41.1 microCi +/- 1.2 microCi = 1520 kBq +/- 44 kBq, beta-emitting (55Co) stents.

- The study evaluated how high-activity beta-emitting (55Co) stents remodel blood vessels after implantation using intravascular ultrasound (IVUS) in 10 patients.
- Results showed that while there was significant reduction in lumen volume within the stent due to neointimal hyperplasia, total vessel volume and plaque/media volume remained unchanged.
- However, edge restenosis occurred mainly from neointimal proliferation at the stent extremities, revealing that the stents are effective in reducing hyperplasia within the stent body but not at the edges.
