Preoperative design of surgical approach on stem cell transplantation via stereotactic surgery / 中华神经医学杂志

ABSTRACT

Objective To evaluate the influence and significance of preoperative design of surgical approach on stem cell transplantation via stereotactic surgery. Methods Six patients with stroke in the basal ganglia region were selected. The transplantation target and transcranial approach point were designed by magnetic resonance examination before stem cell transplantation via stereotacfic surgery to guarantee that the line connecting the transplantation target and transcranial approach point could avoid the important functional areas, the ventricular system and the softening focus. Postoperative magnetic resonance examination was performed to observe whether the practical target and surgical approach coincided with the preoperative design or not. Results The practical transplantation target was coincided with the designed transplantation target, distributed around the softening focus without implanted cells in the softening focus. Surgical approach was coincided with the preoperative design and it successfully avoided the important brain functional area, ventricular system and softening focus.Conelnsion The preoperative design of surgical approach can not only ensure the cells being exactly transplanted into the reservation target and guarantee the curative effect, but also promise the surgical approach successfully avoiding the important brain functional area, ventricular system and softening focus and reduce the operative injury.
