Persistent type IV hypersensitivity after cyanoacrylate closure of the great saphenous vein

J Vasc Surg Cases Innov Tech. 2019 Aug 7;5(3):372-374. doi: 10.1016/j.jvscit.2019.05.004. eCollection 2019 Sep.


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.
