[Microsurgical anatomy of sellar region in cadavers using a photographic technique with fluorescein].
The microsurgical anatomy of sellar regions in 20 cadavers with a 12 hours maximum post mortem was studied. Fluorescein was used as contrast for vascular anatomy examination. The use of fresh specimen and fluorescein had the objective of avoiding any distortion of normal anatomy. The drug was diluted with water or, in order to have more consistency, in gel for ultrasonography. Contrast injection was made into the internal carotid artery and photographs were taken with three different kinds of lighting: 1) only with Wood's lamp; 2) Wood's lamp and normal white light; 3) only with white light. Lighting only with Wood's lamp showed more contrast. After measurement, data often showed discrepancies with other authors' data. The photographic technique with fluorescein is simple and accessible; the drug showed high quality as a vascular contrast for neuroanatomic research.
