title: Cardiac Arrest after Patent Blue V Injection for Sentinel Lymph Node Biopsy in Breast Cancer.
abstract: SUMMARY: BACKGROUND: Sentinel lymph node biopsy (SLNB) is a widely accepted method to determine lymph node status in for instance breast cancer, cervical cancer, or cutaneous melanomas. Although injection of blue dyes facilitates successful detection of sentinel nodes, they have also been shown to cause adverse reactions. CASE REPORT: A 62-year-old female patient was referred to the surgical department of the Atrium Medical Centre with a suspicious lesion located in the right breast, detected during population-based screening. Immediately after injection of patent blue V, the patient developed tachycardia on top of preexisting supraventricular tachycardia and showed an instant drop in blood pressure, after which cardiac arrest occurred. These clear symptoms of anaphylactic shock required prompt treatment, and the patient was treated accordingly. CONCLUSIONS: Anaphylactic shock after injection of patent blue V remains a serious adverse event and warrants awareness. Immediate action with ephedrine, antihistamines, and subsequently corticosteroids can stabilize the patient. Tc-99m, isosulphan blue, and methylene blue can alternatively be used for SLNB, although also not without side effects.
