Contrast-Induced Encephalopathy: A Case Series Analysis.
Background: Contrast-induced encephalopathy (CIE) is a rare adverse event linked to intravascular use of iodine-containing contrast media. The prevalence of CIE could increase in the future due to growing numbers of endovascular procedures. We provide insights from a case series of 7 patients.
Methods: Cases from 3 centers were collected based on existing academic collaborations, and key factors were extracted to illustrate development and management of CIE.
Results: In our retrospective case-series analysis of 7 cases from 3 countries, affected patients had an equal distribution of sex (4 women, 3 men) and a median age of 75 (IQR 63-77). Common risk factors included hypertension (5/7), hyperlipidemia (5/7), previous stroke (3/7), and type 2 diabetes (3/7). CIE developed in 3 cases after endovascular thrombectomy (EVT) for stroke, in 2 cases after aneurysm treatment, in 1 case after cardiac catheterization, and in 1 case after diagnostic computed tomography (CT) angiography without an endovascular procedure. The median procedure time was 48 min (IQR 40-81). All patients received non-ionic, low-osmolar contrast agents with volumes ranging from 100-300 ml. Symptom onset was close to contrast administration, with stroke-like neurological deficits being most common (4/7). Prednisolone was the most frequently used medication to treat the symptoms (4/7). Symptom resolution occurred in 4 out of 7 patients within two to several days, and 1 patient died, but without clear connection to CIE.
Conclusion: CIE is a rare and possibly underrecognized condition, but fortunately, with a favorable outcome in most cases.
期刊介绍:
The journal has a clinical foundation and has been utilized most by clinical neurologists for improving the practice of neurology. While the focus is on neurology in India, the journal publishes manuscripts of high value from all parts of the world. Journal publishes reviews of various types, original articles, short communications, interesting images and case reports. The journal respects the scientific submission of its authors and believes in following an expeditious double-blind peer review process and endeavors to complete the review process within scheduled time frame. A significant effort from the author and the journal perhaps enables to strike an equilibrium to meet the professional expectations of the peers in the world of scientific publication. AIAN believes in safeguarding the privacy rights of human subjects. In order to comply with it, the journal instructs all authors when uploading the manuscript to also add the ethical clearance (human/animals)/ informed consent of subject in the manuscript. This applies to the study/case report that involves animal/human subjects/human specimens e.g. extracted tooth part/soft tissue for biopsy/in vitro analysis.
