Posterior lateral choroidal artery in antero-posterior angiographic projection

Opacification of the lateral posterior choroidal artery in antero-posterior projections was analysed in 282 left-sided brachial angiograms. In 40.5% of cases the artery was sufficiently opacified to evaluate its course. The authors report the time intervals for filling of the artery in normal angiograms. The pattern described may serve as a basis for the evaluation of the displacement of the lateral posterior choroidal artery by midline tumours.
