Summary
Transient cortical blindness is a rare complication following coronary angiography. This case highlights a potential neurotoxic effect of X-ray contrast media, with symptoms resolving quickly.
Area of Science:
- Cardiology
- Neurology
- Ophthalmology
Background:
- Coronary angiography is standard for diagnosing ischemic heart disease, with high procedure volumes.
- Cerebral complications like stroke are rare after coronary procedures.
- Transient cortical blindness is an uncommon complication, typically associated with cerebral angiography.
Observation:
- A 32-year-old man with ventricular arrhythmias and reduced ejection fraction underwent coronary angiography.
- The patient experienced transient cortical blindness immediately post-procedure.
- No arterial lesions were identified, and neurological/ophthalmological exams were normal.
Findings:
- Transient cortical blindness occurred directly after coronary angiography.
- The event is potentially linked to the neurotoxic effects of X-ray contrast media.
- Complete visual recovery was observed within hours.
Implications:
- This case underscores the rare but possible neurotoxicity of contrast agents used in coronary angiography.
- Prompt recognition and monitoring are crucial for managing this adverse event.
- Further research may clarify the mechanisms and risk factors for contrast-induced neurotoxicity.

01:26Transient Ischemic Attack l: Introduction
18
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...

01:30Acute Coronary Syndrome I: Introduction
2.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

2.0K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
