To report a case of type IV hypersensitivity reaction following cyanoacrylate closure of the great saphenous vein and to discuss the implications of cyanoacrylate extravasation, particularly its potential to cause significant postoperative complications.
Key Findings:
Cyanoacrylate extravasation can lead to encapsulated mass formation related to type IV hypersensitivity, indicating a need for careful monitoring.
Histological analysis revealed a predominance of CD4+ T cells and M2 macrophages, indicating a T4H response, which is crucial for understanding the immune mechanism.
Surgical intervention resulted in complete wound healing, demonstrating the effectiveness of surgical management in this case.
Interpretation:
The findings suggest that large encapsulated masses due to cyanoacrylate are rare, emphasizing the need for awareness of T4H reactions in patients undergoing cyanoacrylate procedures and their potential complications.
Limitations:
The case is singular and may not represent the broader population, limiting generalizability.
No immunomodulatory treatments were tested in this case, which could provide insights into alternative management strategies.
Conclusion:
Surgical therapy was effective in resolving the hypersensitivity reaction, but further research into immunomodulatory treatments, such as calcineurin inhibitors or TNF-α inhibitors, could reduce the need for surgical interventions.
