Catheter-induced anaphylaxis and determination of the causative catheter in a patient undergoing neuroendovascular surgery: a case report

Abstract

Abstract Background Anaphylaxis caused by a catheter itself used for endovascular surgery is rare, and a method for detection of a causative catheter has not been established. We report a case of catheter-induced anaphylaxis in which the causative catheter was successfully detected. Case presentation A 47-year-old male underwent neuroendovascular surgery. During surgery, blood pressure suddenly dropped and the level of tryptase indicated the occurrence of anaphylaxis. There were 24 candidate agents for the cause of anaphylaxis including 8 catheters. We performed the basophil activation test by directly mixing the catheter with blood. One catheter coated with a hyaluronic acid product showed a positive reaction, and we confirmed the result by a modified skin test using an elution solution of the catheter. Later, we successfully completed the neuroendovascular surgery without the catheter. Conclusions The methods used in this case can be useful for the detection of the causative agent in catheter-induced anaphylaxis.
