This article reports on a patient who was examined 5.5 years after both gsvs were treated with cyanoacrylate closure (venaseal) for chronic venous insufficiency cyanoacrylate closure, and a segment of great saphenous vein was excised for histopathologic analysis.Findings were typical of a foreign body reaction.The patient agreed to have a segment of the left gsv, previously treated with 1.4 ml of cyanoacrylate, excised for histopathologic analysis.Under local anaesthesia, a segment of the treated left gsv was surgically excised from the midthigh region.The results of the histopathologic analysis showed that the treated gsv was still occluded, contained polymer remnants, and had characteristics typical of a foreign body reaction.Small areas of neovascularization or recanalization were identified with sma staining; however, the fibrotic or occlusive process clearly dominated in this cyanoacrylate-treated segment.The presence of multinucleated giant cells and granulomatous inflammation in this case is consistent with the prolonged course of a foreign body reaction.Implantation of a foreign material provokes a staged response from surrounding tissues and includes inflammation, wound healing, and foreign body reaction.The response transitions through acute inflammation into a foreign body reaction that continues as long as the implanted material stays in the tissue.
