Intravascular ultrasound study of the effect of beta-emitting (Co-55) stents on vascular remodeling and intimal proliferation
Original language description
The aim of this study was to evaluate vessel remodeling after implantation of high-activity (mean, 41.1 +/- 1.2 muCi) beta-emitting ((CO)-C-55) stents. Proton bombarding in cyclotron has brought the radioactivity. Intravascular ultrasound (IVUS) investigation has been completed in 10 patients. The angiographies performed at 6 months revealed restenosis > 50% in five cases (50%). IVUS analysis demonstrated an absence of remodeling behind the stent, with no changes in total vessel volume (TVV; 353.6 +/- 126.3 and 343.9. +/- 90.6 mm(3)) or plaque + media volume (PMV; 171.7 +/- 57.4 and 166.8 +/- 42.6 mm(3)). On the other hand, lumen volume (LV) within the stent decreased significantly from 181.9 +/- 80.2 to 154.6 +/- 45.2mm(3) (P < 0.02). This was due topresence of neointimal hyperplasia (NIH) at both extremities of implanted stents. No chronic recoil of the implanted stents was found. The analysis of edges (5 mm distally and proximally to the last stent struts) showed no significant ...

Intravaskulární echografická studie efektu beta-emitnujícího (55Co) stentu
Czech description
Byla provedena IVUS analýza "edge efektu" po implantaci radioaktivních stentů (majoritní zářič Co-55) zaktivovaných svazkem urychlených protonů z cyklotronu. Efektivní redukce neointimální hyperplasie je patrná v okolí tělesa stentu zatímco na krajích stentu dochází v 66% případů k restenózám díky intimální proliferaci.
