Use of 3DFT-CISS sequences and virtual MR endoscopy for the neuroendoscopic treatment of unilateral hydrocephalus: case illustration.

Objective: Intraventricular virtual MR endoscopic imaging of the foramen of Monro region by using three-dimensional Fourier transformation constructive interference in steady state (3DFT-CISS) magnetic resonance imaging in a patient with a unilateral congenital obstruction of the foramen of Monro by a transparent membranous septum was performed to enhance the orientation, achieve a better understanding of the pathology, and plan the surgical intervention in an endoscopic approach to the lateral ventricles.

Methods: 3DFT-CISS sequences and virtual MR endoscopic imaging were performed in a patient before and after endoscopic fenestration procedures, to communicate the lateral ventricle to the third ventricle for the treatment of unilateral ventricular enlargement.

Results: Preoperative 3DFT-CISS imaging demonstrated unilateral membranous septa in the localization of the left foramen of Monro which were not observed with routine T2-weighted imaging.

Using the magnetic resonance three-dimensional volume rendering for tissues technique in the planning of craniotomy flaps with linear scalp incision.

Preoperative three-dimensional images with surface venous anatomy may be used in the planning of a linear scalp incision and the opening site of the dura mater for protection of surface veins during surgical dissection, and to find the splitting site of the brain according to the lesion. In 45 patients who had a brain tumor, linear scalp incision planning was done by regarding the three-dimensional images derived from post-contrast time-of-flight (TOF) sequence raw data. The findings of correspondence and the quality of routine contrast-enhanced magnetic resonance imaging (MRI) and three-dimensional volume rendering for tissues (VRT) images were analyzed separately with the surgical findings according to a visual grading system.

A model of unilateral frontal focal cerebral venous occlusion in the rat.

Objective: The aim of this experimental study was to create a new focal venous infarction model in rats.

Method: 20-male Sprague-Dawley rats were used in this experiment. Unilateral frontal strip craniectomy was done in front of the coronal suture.

The borders of the odontoid process of C2 in adults and in children including the estimation of odontoid/body ratio.

The odontoid process of C2 projects upward from the superior roof of the body of C2. There is a confusion about the inferior border of the odontoid. The aims of this clinical study were to describe the inferior border of the odontoid process based on the remnant of dentocentral synchondrosis in adults, and the estimation of the odontoid/body ratio in pediatric and adult ages.

Reconstruction of burr hole by using autologous button-shaped graft harvested from inner table of craniotomy flap: technique and clinical result.

Patients who underwent craniotomy occasionally complain about the postoperative cosmetic appearance at the site of burr holes on the scalp. This problem occurs as a result of depletion of the skin into the unreconstructed burr holes. Some materials have been developed for reconstruction of craniotomy burr holes.
