Riassunto
Le procedure di radiologia interventistica a guida fluoroscopica studiano la vascolarizzazione e le potenziali patologie ad essa connesse utilizzando le radiazioni ionizzanti per guidare piccoli strumenti, quali i cateteri, attraverso i vasi sanguigni. La tecnica fluoroscopica è diventata parte integrante della pratica radiologica sin dall’inizio del XX secolo. Inizialmente le procedure di fluoroscopia erano, per la maggior parte, di tipo diagnostico, miravano cioè solo a identificare un problema clinico, e comportavano rischi relativamente piccoli per i pazienti e il personale coin volto. Tuttavia, negli ultimi 20 anni, la percentuale di procedure terapeutiche è aumentata progressivamente [1]. Si è assistito negli ultimi decenni a un crescente ampliamento delle possibilità procedurali nell’ambito dell’interventistica fluoroscopica, anche grazie allo sviluppo di sempre nuove tecnologie. Trattamenti quali vertebroplastiche, ablazioni a radiofrequenza, chemioterapie intra-arteriose, endoprotesi aortiche e rivascolarizzazioni arteriose periferiche costituiscono oggi parte integrante della pratica clinica in numerosi centri a livello mondiale per i trattamenti in ambito vascolare e oncologico. Di fronte alla crescita della richiesta di prestazioni interventistiche, la ricerca industriale ha implementato progressivamente la strumentazione, introducendo sistemi a basso profilo (quali catereri, palloncini e guide) specifici per ciascun distretto vascolare e non. Tale strumentazione consente oggi il trattamento di strutture sempre più periferiche e di piccolo calibro, a fronte di una minore incidenza di complicanze e di un maggior successo procedurale.
