Randomized Controlled Trial Clinical Trial[Role of diffusion tensor imaging in neuronavigation surgery of brain tumors involving pyramidal tracts].
To explore the role of diffusion tensor imaging (DTI) in neuronavigation surgery of brain tumors involving pyramidal tracts. ⋯ DTI allows individual estimation of large fiber tracts of brain. Furthermore, to integrate spatial three-dimensional information concerning the white matter tracts into traditional neuronavigation images during surgery, was valuable in presenting topographical character of involving (shift or erosive) pyramidal tracts and relationship with the margins of neighboring tumors. The mapping of large fiber tracts was a safe, efficient, reliable technique. DTI should be routinely used in neuronavigation surgery of brain tumor involving pyramidal tracts to plan the optimal trajectory and ensure total resection of the lesions during operation, as well as to decrease potential disability after operation and to shorten the length of hospitalization.

[Video-assisted thoracoscopic left sympathectomy for the treatment of congenital long QT syndrome].
To assess the feasibility, safety and effectiveness of video-assisted thoracoscopic sympathectomy (VATS) for the treatment of congenital long QT syndrome. ⋯ VATS is a safe as well as an effective technique for the treatment of congenital long QT syndromes.

[The relation and evaluation of the vertebral artery and the nerve root to posterior lateral mass screw fixation].
To determine the location of the vertebral artery foramens from C(3) to C(6) and their relationship to the point 1 mm medial to the center of the lateral mass and to identify the value of oblique radiograph for cervical lateral mass screw trajectory by a cadaveric study. ⋯ (1) There is no risk of damaging the vertebral artery if a screw is directed more than 15 degrees lateral to the sagittal plane at C(3 approximately 6) starting 1 mm medial to the center of the lateral mass. (2) Ideal screw tip position on oblique radiograph may not cross the line connecting the posterior borders of the intervertebral foramen on radiograph. If the screw tip is noted in the superior part of intervertebral foramen on the oblique radiograph, the screw may be identified as dangerous.

[Coronary artery bypass graft for patients with ascending aorta atherosclerosis].
The increasing number of aged patients with severe ascending aorta atherosclerosis who are undergoing coronary artery bypass graft (CABG) present high risk for ascending aortic cannulation, cross-clamping or partial occluding and proximal anastomosis. We reviewed the surgical experience in 22 patients of CABG with ascending aorta atherosclerosis and tried to find the way to minimize the complications. ⋯ CABG on beating heart with pedicel arterial grafts is the best approach to performing the surgery without touching the diseased ascending aorta. Ventricular fibrillation under mild hypothermia cardiopulmonary bypass and left ventricular suction were employed for quiet and bloodless field while distal anastomosis had no cross-clamping the ascending aorta. Also deep hypothermia and intermittently circulatory arrest offer quiet and bloodless field for the proximal anastomosis on ascending aorta without cross-clamping or partial-occluding. Distal sequential anastomosis and proximal "Y" type anastomosis are the effective approach to minimizing the proximal anastomosis on the ascending aorta.

[Ultrasound surveillance of cervical lymph node metastasis in thoracic esophageal carcinoma].
To improve the accuracy of preoperative evaluation of cervical lymph node metastasis in thoracic esophageal squamous carcinoma. ⋯ Neck ultrasonography for cervical lymphadenopathy is of high sensitivity and accuracy, which plays an important role in the preoperative evaluation and therapeutic decision-making.
