Temporary cortical blindness following angiography

Abstract

✓ Temporary cortical blindness as a complication of posterior angiography is reported in 11 patients and compared with 30 similar cases previously reported. Theoretical considerations of etiology implicate transitory alterations of the blood-brain barrier in the striate cortex.

Cortical Blindness, Transient and Otherwise, Associated with Detachable Coil Embolization of Intracranial Aneurysms

“…Transient cortical blindness is a rare but known complication after administration of angiographic contrast agent, 3 which has been reported in 0.3%-1% of patients undergoing vertebral angiography. 4,5 The prevalence could be higher in patients with vasculopathy, even with carotid artery injections, 6 or with older techniques.…”

Transient cortical blindness after thoracic endovascular aneurysm repair

“…It has been reported in several types of diagnostic procedures using contrast, including aortography, coronary angiography, and imaging of all of supraaortic vessels. [1][2][3][4] In cerebral and vertebral angiography, TCB has been demonstrated to occur at a rate of 0.3% to 1.0%. 2,[5][6][7] This rate is much lower for other types of angiography.…”

“…[1][2][3][4] In cerebral and vertebral angiography, TCB has been demonstrated to occur at a rate of 0.3% to 1.0%. 2,[5][6][7] This rate is much lower for other types of angiography. 8,9 Diagnosis of TCB is made by clinical examination and imaging evaluation to rule out other pathologies.…”

Bilateral Occipital Infarcts in a Hemodialysis Patient

“…The computerized tomographic scan findings of bilateral occipital infarcts confirmed the diagnosis. Cortical blindness as a complication of hemodialysis has been reported in the pediatric age group [4] and also has been reported following cardiac arrest [5] and vertebral angiography [6].…”
