IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
EnglishPurpose of review: This article critically analyzes the recent literature on microvascular head and neck reconstruction after (chemo)radiation [(C)RT], taking into consideration both the underlying pathogenetic mechanisms and their clinical consequences. Recent findings: Microvascular reconstruction has gradually become a mainstay in the management of head and neck cancer both in primary and salvage scenarios. However, limited data are available concerning the influence of previous radiotherapy/chemoradiation therapy (CRT) on free flap survival and surgical complications. Molecular studies show that the effects of radiotherapy/CRT may be essentially reduced to three components: inflammation, a prothrombotic state and fibrosis. From a clinical point of view, this is reflected in a moderate increase in free flaps failure and surgical complications. Nevertheless, free flaps continue to offer clear advantages even in such an unfavorable condition. Summary: Radiotherapy/CRT induce a less favorable tissue environment, potentially leading to a higher risk of complications. In this scenario, however, free tissue transfer still plays the role of favoring wound healing bringing well vascularized tissue to less vascularized microenvironments.
