Özet

Transient cortical blindness after coronary angiography or angioplasty is a rare complication. Patients with aortocoronary bypass grafts such as internal mammary artery have a seperate risk factor probably because of the direct contrast injection to the vertebral artery during the catheterisation of the internal mammary artery ostium. In most cases, computed tomography scan revealed typical, symmetrical contrast enhancement in both occipital lobes Nevertheless, transient cortical blindness can be seen after coronary angiography without contrast enhancement at computed tomography scan.
