A Possible Allergic Reaction Case to Thrombin Injected into Pseudoaneurysm After Radiofrequency Ablation

Patient: Female, 82 Final Diagnosis: Possible allergy to thrombin Symptoms: Palpitation Medication: Bovine thrombin Clinical Procedure: Radiofrequency ablation Specialty: Cardiac Surgery OBJECTIVE: Unusual clinical course BACKGROUND: Radiofrequency ablation is a minimally invasive treatment for arrhythmias, including frequent ventricular premature. As a complication of radiofrequency ablation, pseudoaneurysm can be treated conservatively or by ultrasound-guided thrombin injection. CASE REPORT: We report a case that a possible allergic reaction to thrombin injected into pseudoaneurysm after radiofrequency ablation. CONCLUSIONS: We hope that the report of successful management of the allergic reaction in this case may be of help to other doctors; we also emphasize the importance of checking the patient’s history of allergies to thrombin when considering treating pseudoaneurysm with thrombin injection.
