Summary
Transient cortical blindness is rare after coronary angiography. This case highlights a potential risk with iobitridol, a modern contrast agent, emphasizing the need for continued vigilance in diagnostic procedures.
Area of Science:
- Radiology
- Ophthalmology
- Cardiology
Background:
- Transient cortical blindness (TCB) is a rare complication following contrast media administration.
- While previously associated with older contrast agents during cerebral angiography, its occurrence with modern non-ionic, low-osmolality agents during coronary angiography is infrequently reported.
Observation:
- This report details a case of abrupt TCB in a patient undergoing diagnostic coronary angiography.
- The event occurred shortly after exposure to the contrast agent iobitridol.
Findings:
- This represents the first documented instance of TCB associated with the use of iobitridol in medical literature.
- The patient experienced a temporary visual deficit, consistent with transient cortical blindness.
Implications:
- Clinicians should be aware of the potential for TCB even with newer contrast agents like iobitridol.
- Further investigation may be warranted to fully understand the risk profile of iobitridol concerning neuro-ophthalmic complications.

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:26Cardiac Catheterization IV: Nursing Management
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
01:28Cardiac Catheterization I: Pre-Procedure Overview
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
