Abstract
Fibroblastic sleeve is a common pathophysiological phenomenon characterized by the formation of a mixed fibrous-collagen tissue encasing the outside of venous access devices. Although it nearly always presents asymptomatically, this catheter-related complication represents one of the leading culprits of venous catheters malfunction. Several techniques have been described for the management of dysfunctional catheters secondary to fibroblastic sleeve, including medical therapy, catheter exchange, balloon angioplasty, and percutaneous stripping. However, there is no common consensus for the treatment management in patients who present contraindications to surgical port removal. This report illustrates the case of a port catheter malfunction due to a fibroblastic sleeve in an oncological patient with a high risk of bleeding. This was effectively treated with a minimally invasive stripping technique using an off-label device for mechanical thrombectomy, namely the ClotTriever system (Inari Medical, Irvine, CA).
