Insights

Transient cortical blindness after cerebral angiography is rare but linked to higher contrast agent doses and posterior circulation injections. Identifying these risk factors is crucial for patient safety.

Area of Science:

  • Neurology
  • Radiology
  • Ophthalmology

Background:

  • Transient cortical blindness is a rare but significant complication following cerebral angiography.
  • Identifying risk factors for this complication is clinically important for patient management and safety.

Purpose of the Study:

  • To identify independent predictive factors for transient cortical blindness after cerebral angiography.

Main Methods:

  • A multicenter cohort study involving 5,126 patients who underwent cerebral angiography.
  • Analysis of patient baseline characteristics and procedure-related factors using multivariate logistic regression.

Main Results:

  • Eighteen patients (0.35%) experienced transient cortical blindness.
  • Higher contrast agent dose and injection into the posterior circulation were identified as independent predictive factors (P < 0.05).
  • No significant differences were found regarding gender, age, smoking, diabetes, or hypertension.

Conclusions:

  • Increased contrast agent dose and posterior circulation contrast injection are potential independent risk factors for transient cortical blindness post-cerebral angiography.
  • These findings can inform strategies to mitigate the risk of this complication.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Transient 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.
