Video-assisted thoracic surgery thymectomy for myasthenia gravis

Video-assisted thoracic surgery thymectomy was employed in the management of myasthenia gravis in a series of 20 patients. As the technique evolved, the authors preferred a right-sided approach, and the technical details of the process are discussed. At a mean follow-up of 30 months, clinical results are comparable to published series of other approaches. It is hoped that the superior cosmesis associated with this less-invasive approach leads to earlier thymectomy in management of this disease.     

Cerebrospinal fluid fistula: detection with MR cisternography

PURPOSE: Our goal was to assess the role of MR cisternography in the examination of patients with suspected CSF rhinorrhea. METHODS: MR cisternography was performed as a heavily T2-weighted fast spin-echo study with fat suppression and video reversal of the images in 37 patients over a 3-year interval. Twenty-four of the patients subsequently had exploratory surgery for fistula. Statistical analysis of the surgical results was compared with the findings at MR cisternography. RESULTS: MR cisternography showed significant correlation with surgical findings, with sensitivity, specificity, and accuracy of 0.87, 0.57, and 0.78, respectively. CONCLUSION: MR cisternography proved to be an accurate diagnostic imaging technique in the evaluation of suspected CSF rhinorrhea.
