Anatomic research of the subtemporal transpetrosalridge approach / 中华外科杂志

<p><b>OBJECTIVE</b>Subtemporal transpetrosal ridge approach (STA) was introduced to remove the petroclival meningiomas with the simple, safe and minimal invasive character. It is suggested to replace the combined approach to reduce the morbidity and mortality.</p><p><b>METHODS</b>Surgical anatomic study was done on 10 adult cadaver heads fixed in 10% formalin and 10 dry skulls. Ten cadaver heads were examined by bone-window CT scan pre and post-operation. The relationships of important anatomic structures and positions were measured and photographed.</p><p><b>RESULTS</b>For the STA, the important structures include Vein of Labbe, petrous bone and brain stem ventral space. The important data include the drilling space of the petrous ridge.</p><p><b>CONCLUSIONS</b>STA is an original approach to remove petroclival meningiomas. By drilling the petrous ridge, it allows the resecion of the tumor simple, safe and minimal invasive. It is suggested to replace the combined approach with STA to diminish the morbidity and mortality.</p>

The diagnosis and microsurgical treatment of solid cerebellar hemangioreticuloma / 中华外科杂志

<p><b>OBJECTIVE</b>To study the clinical features, neuroimaging presentations, diagnosis and differential diagnosis, and operative warning events of the solid cerebellar hemangioblastoma.</p><p><b>METHODS</b>The clinical data of 48 patients with solid cerebellar haemangioreticuloma were retrospectively analysed. Preoperative examinations included CT and MRI in all patients, DSA in 20, preoperative embolization of feeding arteries of tumor in 16, a preoperative ventriculoperitoneal shunt was placed in 5 cases. The lesion distribution of 48 patients was as follows: 14 lesions were situated in the left hemisphere of cerebellum with an extent into the cerebellopontine angle in 2 cases, 12 in right hemisphere of cerebellum, 8 in superior vermis, 7 in inferior vermis, 6 in left subtentorium, 1 in left cerebellar tonsil.</p><p><b>RESULTS</b>The tumors of 48 patients were totally removed. One patient occurred normal perfusion pressure breakthrough during surgery, and gastrointestinal hemorrhage on the second day after operation. Other patients all were intra- and postoperatively uneventful. Except for autoinfusion, no patients transfused heterogenous blood. There were no operative mortality and serious complications in this series.</p><p><b>CONCLUSIONS</b>The solid cerebellar hemangioblastoma was benign neoplasm. Abiding by properly operative techniques, the optimal results can be obtained.</p>
