Objective: Cyanoacrylate closure (CAC) is a minimally invasive technique for the treatment of varicose veins. A recent paper reported serious adverse events (AEs) associated with this use. This triggered an urgent survey to determine the incidence of AEs in Japan.

Methods: The CAC-AE survey was sent to all 1,030 institutions authorized for CAC treatments. Cases performed between January 2020 and October 2023 were surveyed. Data on serious AEs and mortality were collected.

Results: There were 623 surveys returned. There were 16 cases of proximal deep vein thrombosis, 3 cases of pulmonary embolism (PE), and 0 cases of stroke. Deep vein occlusion due to cyanoacrylate extension was observed in 1 case. Vein resection due to infection was observed in 4 cases. There were 299 cases of localized phlebitis and/or allergic reactions requiring steroid administration. Systemic allergic reactions requiring steroid administration were observed in 66 cases. There was no anaphylaxis associated with cyanoacrylate. There was one postoperative death from PE.

Conclusion: This report’s intent is to provide real world data on serious AEs following CAC from Japan given current concern over these events. An extensive report investigation of individual complications with analysis including causality will be provided following a full investigation separately.
