Intraoperative ultrasonography in ＂cave-in＂ 360° circumferential decompression for thoracic spinal stenosis

Chinese Medical Journal 2011年第23期124卷 3879-3885页

作者： wang yong-qiang liu xiao-guang jiang liang jiang ling wei feng yu miao liu zhong-jun Department of Orthopaedics Peking University Third Hospital Beijing 100191 China

The surgical outcomes of decompression for thoracic spinal stenosis （TSS） are unfavorable. The purpose of this study was to determine the efficacy of intraoperative ultrasonography during ＂cave-in＂ 360~ circumferential decompression surgery in patients with TSS. Methods Thirteen patients with TSS underwent ＂cave-in＂ 360° circumferential decompression surgery between May 2010 and November 2010. Intraoperative ultrasonography was used after removal of the posterior wall of thoracic spinal canal to assess the morphologic restoration of the spinal cord and the anterior surface of the spinal canal. In seven patients, ultrasonography was used again after circumferential decompression to compare the cross-sectional area of the spinal cord before and after circumferential decompression. Results The average period of follow-up was （12±2） months （range 9-15 months）. The Japanese Orthopedic Association score was significantly higher at the final follow-up （8.5±2.1, range 3-10） than preoperatively （5.2±1.1, range 3-7; P 〈0.01）. The cross-sectional area of the spinal cord was （30.8±6.6） mm2 before and （53.6±19.1） mm2 after circumferential decompression （P 〈0.01）. For five patients with TSS caused by thoracic disc herniation, the levels of circumferential decompression performed corresponded to those expected preoperatively. In contrast, for eight patients with TSS caused by ossification of the posterior longitudinal ligament, on average 1.6±0.9 fewer levels of circumferential decompression were performed than expected preoperatively. Conclusions ＂Cave-in＂ 360° circumferential decompression is an effective therapeutic option for TSS. Intraoperative ultrasonographic evaluation may reduce the levels of circumferential decompression and ensure sufficient decomoression, and increase the efficacy of this surqical technique.

The process of development and calibration for the first Moon-based ex- treme ultraviolet （EUV） camera to observe Earth＇s plasmasphere is introduced and the design, test and calibration results are presented. The EUV camera is composed of a multilayer film mirror, a thin film filter, a photon-counting imaging detector, a mech- anism that can adjust the direction in two dimensions, a protective cover, an electronic unit and a thermal control unit. The center wavelength of the EUV camera is 30.2 nm with a bandwidth of 4.6nm. The field of view is 14.7° with an angular resolution of 0.08°, and the sensitivity of the camera is 0.11 count s-1 Rayleigh-1. The geomet- ric calibration, the absolute photometric calibration and the relative photometric cal- ibration are carried out under different temperatures before launch to obtain a matrix that can correct geometric distortion and a matrix for relative photometric correction, which are used for in-orbit correction of the images to ensure their accuracy.
