Incidence and Clinical Impact of Endovenous Glue-Induced Hypersensitivity Among Patients Who Underwent Endovenous Cyanoacrylate Ablation Procedures: A Registry-Based Cohort Study

Abstract

Background: The characteristics of endovenous glue-induced hypersensitivity (EGIH) remain unclear.

Objective: To assess the clinical impacts on patients with EGIH after endovenous cyanoacrylate-glue ablation (CA).

Materials and methods: A prospectively designed endovenous CA-specific registry was created, and a total of 335 limbs from 173 patients who underwent endovenous CA were enrolled for a cohort study.

Results: Symptomatic EGIH was observed in 55 (31.8%) patients. Beyond the target vein area, systemic side effects were noted in 5.8% of the treated patients after CA. The median onset time was 13 postoperative days (range: 1-35 days). The median duration was 7 days, but about 10.9% of the affected patients experienced symptoms lasting longer than 4 weeks. In the EGIH and non-EGIH groups, significant improvements in venous clinical severity score and Chronic Venous Insufficiency Quality of Life Questionnaire-14 scores were observed 3 months postoperatively. The development of EGIH did not affect the postoperative patient-reported satisfaction scores ( p = .524).

Conclusion: EGIH is observed in a substantial proportion of patients. The side effects do not affect the clinical outcomes and patient-reported outcome measures. Further studies are required on the detailed pathogenesis and definition of EGIH.
