Complications of Endovascular Polymers Associated With Vascular Introducer Sheaths and Metallic Coils in 3 Patients, With Literature Review

Abstract

Hydrophilic coating may dislodge and induce a prominent foreign-body granulomatous response or microabscesses. Although the culprit radial artery sheath is now rarely used, embolization coils containing polymers are commonly deployed in clinical practice and may be a source of recurrent inflammatory lesions.
