[A male patient with acute, reversible blindness].

Background: Intra-arterial thrombectomy (IAT) in occlusions of the posterior cerebral artery (PCA) is uncommon and not a proven therapeutic solution, but can be performed in individual cases.

Case Description: An 80 year old man visited the emergency room after experiencing acute blindness. This was caused by a new hemianopia for the left visual field due to an occlusion of the right PCA, on top of a pre-existing hemianopia for the right visual field.

Three-dimensional ultrasound imaging of fetal brain fissures in the growth restricted fetus.

Objectives: To examine differences in growth trajectories of fetal brain fissures in the growth restricted fetus (FGR) compared to controls.

Methods: We selected a subgroup of 227 women with a singleton pregnancy from the Rotterdam Periconceptional Cohort. Participants received three-dimensional ultrasound (3D-US) examinations of the fetal brain at 22, 26 and 32 weeks of gestational age (GA).

Prenatal influence of congenital heart defects on trajectories of cortical folding of the fetal brain using three-dimensional ultrasound.

Objective: The objective of the study is to investigate the prenatal influence of congenital heart defects (CHD) on trajectories of fetal cortical folding using three-dimensional ultrasound (3D US).

Method: We included 20 CHD fetuses and 193 controls for studying the fetal brain at 22, 26 and 32 weeks' gestational age (GA). The Sylvian, insula and parieto-occipital fissure (POF) depths were measured using 3D US, and reliability was evaluated.
