Microsurgericai anatomy and value for clinical application of choroidal fissure

Objective To explore the microanatomical feature of choroidal fissure and the value for clinical application of transchoroidal approach. Methods Twelve adult cadaveric wet brains were dissected under microscope with magnification ranging from 4 to 10 times, the microanatomical feature of the choroidal fissure was observed and described. The approach to the third vertricle, the region of corpus pineale and ambient cistern from the lateral ventricle through choroidal fissure were observed. Results In the body of the lateral ventricle, the choroid plexus was located in the medial part of the floor. The choroidal fissure was a C-shaped natural cleft between the thalamus and the fornix, being white translucent membranes. The cavity of the third vertricle was reached through the body of choroidal fissure, the region of corpus pineale via the antrum and ambient cistern via pars temporalis. Conclusions The transchoroidal approach which follows a natural route is of advantages of less injury and wider exposure. An understanding of the choroidal fissure is fundamental for using of the transchoroidal approach.
