Objective To investigate the CT signs of small intracranial aneurysm and the application value of multi-slice spiral CT angiography (MSCTA) before and after clipping surgery and in follow-up.Methods MSCTA imaging data of 81 patients with highly suspected small intracranial aneurysms from March 2013 to March 2015 were analyzed retrospectively.The confirmed patients underwent clipping surgery of small intracranial aneurysms.The imaging findings before and after clipping surgery were analyzed and compared with those by DSA and what observed during surgery.Results The relative accuracy,sensitivity and specificity of MSCTA over DSA and surgical diagnosis were 93.83％,93.75％ and 94.12％respectively,and MSCTA gained high relative consistency over DSA and surgical diagnosis (Kappa=0.825).The accuracy of MSCTA for diagnosing small intracranial aneurysm was not significantly different from those by DSA and surgical diagnosis.MSCT plain scan mainly showed subarachnoid or intracranial hemorrhage,and found 71 rhomboic or saccular aneurysms in 60 patients before operation.Totally 64 patients went through clipping surgery,60 ones had satisfactory results in the reexamination by MSCTA 2 weeks after surgery,and there were no abnormality found in 36 patients in 6 to 12-month follow-up.Conclusion MSCTA can provide abundant information for clipping surgery of small intracranial aneurysms,and can be used as the preferred imaging method for postoperative evaluation and follow-up.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.
