Incidence of fibroblastic sleeve and of catheter-related venous thrombosis in peripherally inserted central catheters: A prospective study on oncological and hematological patients.

Fibroblastic sleeve is a frequent (29.9%) but asymptomatic finding in oncological and hematological patients with peripherally inserted central catheter, and-in the vast majority of cases-it occurs within 2 weeks after insertion. If compared to fibroblastic sleeve, asymptomatic catheter-related thrombosis is less frequent (5.51%); symptomatic catheter-related thrombosis is rare (<1%).
