Persistent type IV hypersensitivity after cyanoacrylate closure of the great saphenous vein
Journal of Vascular Surgery Cases and Innovative Techniques(2019)
摘要
The VenaSeal (Medtronic, Minneapolis, Minn) cyanoacrylate closure system is a nonthermal technique for ablating saphenous veins using a proprietary n-butyl cyanoacrylate. One possible side effect is an allergic reaction to cyanoacrylate. We report the case of a 49-year-old woman treated with cyanoacrylate closure who developed a persistent type IV hypersensitivity reaction. The patient elected to have the vein excised, and the histologic features were consistent with a type IV hypersensitivity reaction.
