RESUMEN
Objective To study the endovascular management of intradural hemorrhage spontaneous vertebral artery dissection (SVAD) with guglielmi detachable coils (GDCs) and mechanical coils,and explore its therapeutic effect.Methods Four patients with defined intradural hemorrhage SVAD by DSA,admitted to our hospital from January 2008 to December 2011,were chosen in our study;SVAD in 4 patients located in the proximate posterior inferior cerebellar artery.Endovascular management was adopted by evaluating their medical imaging and clinical data.The aneurysms were filled with GDCs,and the parent arteries were performed embolism with mechanical coils.Results No patient died; no aneurysms ruptured and no other severity complications happened during operation.Postoperative angiography showed complete occlusion of SVAD in 4 cases.No rehemorrhagia or ischemia happened during the 6-36 months of follow up.Conclusion Endovascular intervention with GDCs and mechanical coils is a safe and efficacious method for intradural hemorrhage SVAD,which can not only decrease the ratio ofrebleeding,but decrease the surgery cost as well.
RESUMEN
Objective To evaluate the diagnostic evaluation of isotropic scanning and Lung Care soft- ware in solitary pulmonary nodules,and to improve the diagnostic accuracy.Methods 52 patients suffered from SPN were included in our study.Two experts in CT analyzed the films.First,they read the axial images and made diagnosis.Then isotropic scanning and lung care software approaches were used on 16 spiral CT and another analysis were made again.The results were compared with pathological diagnosis respectively. Results Spiculated sign,lobulated sign,vessel convergence were found more on isotropic scanning approach, that had significant difference with axial images analysis(P
