- Immediate Reactions to Fluorescein and Indocyanine Green in Retinal Angiography: Review of Literature and Proposal for Patient’s EvaluationPublication . Meira, Jorge; Marques, Maria Luís; Falcão-Reis, Fernando; Gomes, Eva; Carneiro, ÂngelaIntroduction: Contrast rapid sequence angiography with fluorescein or indocyanine green (ICG) is a diagnostic procedure commonly used in ophthalmology. Adverse reactions to fluorescein and ICG are rare and may be classified as toxic, of hypersensitivity and non-specific. The evaluation and management of a patient with an adverse reaction is a challenge for the majority of ophthalmologists, as is the assessment of risk factors that may contraindicate the procedure. Purpose: We aim to review the concepts underlying adverse reactions to fluorescein and ICG, especially those of hypersensitivity, and present a proposal or the evaluation of the patients in need to perform retinal angiography and for the treatment of immediate reactions to fluorescein and ICG. Methods: The available literature was examined using PubMed-Medline, and using the MeSH terms "fluorescein", "Indocyanine green", "ophthalmic dyes", "retinal angiography", "adverse reactions", and "allergic reaction". Conclusion: This review may help ophthalmologists to identify patients with higher risk of a hypersensitivity reaction and give them tools to recognize patients with suspected hypersensitivity that may benefit from an allergy study.
- Recurrent neck swelling after iodinated contrast media administrationPublication . Cunha, Inês Machado; Maganinho, Pedro; Marques, Maria Luís; Amorim, João Pinheiro; Gomes, EvaA 74-year-old male with an abdominal aortic aneurism reported 2 episodes of neck swelling 16 hours after an abdominal CT with iodinated contrast media that reappeared in a subsequent CT, although the use of pre-medication. The tests used to exclude the hypersensitivity hypothesis where negative and once a new CT where needed we decided to do it with close monitoring. We performed a facial picture and cervical ultrasound exam before and 24 hours after the exam. The neck swelling and the ultrasound findings 24 hours after the CT made the diagnosis of contrast induced sialoadenitis possible. Contrast induced sialadentis is an uncommon adverse reaction to iodinated contrast media. As it presents with neck swelling it is important to exclude a hypersensitivity reaction because it's further limitations and make a differential diagnosis.
