Intramural neovascularization and haemorrhages are major long‐term effects of intravascularγ‐radiation after stenting

Structural changes that might influence the structural integrity of the vessel in response to intravascular brachytherapy (IVB) and stenting were examined, focus being on the importance of neovascularization in rabbit stented arteries. Stents were implanted in the infrarenal aortas of rabbits, immediately followed by gamma IVB or a sham radiation procedure, and the arteries harvested at 6 months. Labelling for von Willebrand factor showed an increase in adventitial and medial neovascularization in irradiated versus control arteries group (5.04+/-0.89 versus 1.51+/-0.23 mm(-2), respectively; p=0.004). Moreover, intramedial haemorrhages (free hemosiderin deposition) and inflammation (macropha…

Infections et infarctus du myocarde : étude prospective multicentrique

Introduction Un lien epidemiologique a ete demontre entre les infections aigues et l’infarctus du myocarde (IDM). Toutefois, la pathogenese et le pronostic des IDM associees aux infections n’a pas fait l’objet d’etude de grande ampleur. Materiels et methodes Tous les patients consecutifs admis pour IDM avec un diagnostic d’infection aigue ont ete prospectivement identifies a partir des donnees d’un observatoire regional des IDM. Le diagnostic d’infection aigue etait a l’appreciation du clinicien. Le diagnostic d’IDM de type 1 (rupture ou erosion de plaque) ou de type 2 (fonctionnel sur desequilibre entre apports et besoins myocardiques en oxygene) etait systematiquement adjudique selon les …
