Objective To compare the therapeutic effect of one-stage direct revascularization and medicine therapy for the treatment of ischemic moyamoya disease. Methods From March 2002 to March 2008, 18 patients with ischemic moyamoyadisease (12 males and 6 females) were treated, aged 9 to 33 years old. Eighteen patients presented with ischemic stroke, including 11 cases of cerebral infarction and 7 cases of transient ischemic attack. According to Chinese ischemic cardiovascular diseases evaluation tools, 17 patients were classified as low risk ischemic stroke and 1 as modernte risk ischemic stroke. Different levels of occlusion branch of the intracranial carotid arteries and pathosis collaterals were identified by DSA. Fourteen patients and 4 patients were showed unilateral and bilateral hypoperfusion of cerebral blood flow by single photon emission computed tomography, respectively. Eleven patients received superficial temporal artery-middle cerebral artery anastomosis and 7 patients received medicine (anti-PLT agglutinin and calcium channel blocker). Results All incisions healed at stage I. There was no stroke events during perioperation. Anastomosis vessel vasospasm occurred in 2 patients 5 days after operation; and hyperperfusion syndrome in 1 patient 2 weeks afteroperation. All patients were followed up 13-32 months (mean 18 months). In 11 anastomosis patients, 6 underwent 6 stroke events within 12 months; in 7 medicine patients, 6 underwent 11 stroke events within 12 months; and showing a significant difference (P lt; 0.05). The stroke recurrence rate was 85.7% in medicine patients and 54.5% in anastomosis patients 12 months after therapy. DSA showed pathosis collaterals in 7 anastomosis patients and 6 medicine patients 6 months after therapy. After 12 months according to modified Rankin scale, the scores of anastomosis patients were 3 points in 1 case, 2 points in 6 cases and 0-1 point in 4 cases, and the scores of medicine patients were 2 points in 2 cases and 0-1 point in 5 cases; showing no significant difference (P gt; 0.05). Conclusion As long as onset of stroke occurred and ischemic moyamoya disease is diagnosed, one-stage direct revascularization should be performed, which can reduce the rate of stroke recurrence risk and slow down the progression of disease.
In recent years, the system of standardized resident training has been set up and improved gradually in our country.However, the medical specialist training system for neurosurgeons is still at the stage of exploration.It is important to cultivate and select the best neurologic surgery specialists in China.Mayo Clinic is one of the best teaching hospitals in the United States, which has been ranking the second in the United States for the recent 20 years.Analyzing the neurologic surgery specialist training program of the world's top hospital and learning from its advanced experiences are beneficial for the establishment of medical specialist training system and the production of the highest caliber neurosurgeons in the Department of Neurosurgery in West China Hospital of Sichuan University.The Department of Neurosurgery in West China Hospital of Sichuan University is advantageous in its advanced technology and equipment, sufficient operations, rich teaching resources and independent laboratories.Our goal is to establish strict accessing, management and assessment system, perfecting security and feedback system, focusing on the cultivation of humanistic spirit, building neurosurgery specialist personnel, and establishing a unique brand of West China in the field of teaching.
Objective To investigate the therapeutic effects of endovascular covered stent on vertebral dissecting aneurysm and carotid-cavernous fistula (CCF). Methods From March 2006 to May 2007, Jostent coronary stent grafts were used to treat 4 patients with vertebral dissecting aneurysm and 3 patients with CCF. The patients of vertebral dissecting aneurysmwere male and 37-57 years old, the lesion was located on the left vertebral artery in 3 patients and on the right vertebral artery in 1 patient, with the primary symptoms of sudden headache and vomiting; CT scan demonstrated subarachnoid hemorrhage; and the medical history varied from 2 days to 10 years. The patients of CCF were male and 35-51 years old, the lesion was located on the left carotid artery in 2 patients and on the right carotid artery in 1 patient, with the primary symptoms of headache, lateral exophthalmos, eyeball distending pain, conjunctive hyperemia and impaired eyesight; all 3 patients got head injury 2 days to 1 month before the appearance of symptoms and 1 of them had a history of severe nosebleed; and the medical history ranged from 1 week to 2 months. Results For the patients with vertebral dissecting aneurysm, complete obl iteration of aneurysms was achieved, the circulations of the vertebral artery, the adjacent posterior inferior cerebellar artery and the adjacent anterior inferior cerebellar artery were smooth, no compl ications relative to operation occurred, and no recurrence of symptoms and intracranial rehaemorrhagia were observed during the follow-up period of 8 months-2 years. For the patients with CCF, the fistula were completely obl iterated, the circulation of carotid artery was smooth, the exophthalmus and conjunctiva hyperemia were improved obviously 3 days after operation, the eyesight of patient was improved at different levels over the follow-up period of 1-3 months. Conclusion Endovascular covered stent is a new and useful tool for the treatment of vertebral dissecting aneurysm and CCF .
目的 探讨显微手术治疗破裂大脑中动脉动脉瘤（MCAA）的适应证、术前评估及手术技巧。 方法 回顾性分析2008年1月－2011年1月经翼点入路行显微外科手术治疗的65例破裂MCAA患者的临床资料。其中男40例，女25例；年龄22～78岁，平均46.8岁。术前Hunt-Hess分级：Ⅰ级15例，Ⅱ级25例，Ⅲ级13例，Ⅳ级10例，Ⅴ级2例。动脉瘤直径＜5 mm 10个，5～15 mm 36个，15～25 mm 15个，＞25 mm 4个，平均7.8 mm。其中56例动脉瘤位于大脑中动脉分叉部，5例位于大脑中动脉的M1段，4例位于分叉后M2段。 结果 手术夹闭动脉瘤60例，余5例行动脉瘤夹闭加包裹术。患者术后获随访3～36个月，平均16个月，均无动脉瘤复发或再出血发生。按格拉斯哥预后评分（GOS）结果评定：恢复良好58例（GOS 4～5分），差5例（GOS 2～3分），死亡2例（GOS 1分）。 结论 充分的术前评估，合适的手术入路选择，以及手术技巧的灵活应用是显微外科手术成功治疗破裂MCAA的保证。
Objective To study the methods and techniques of the treatment forextensive suprasellar pituitary adenona and repairing hole.Methods From Feb. 2001 to Mar. 2003, 9 patients with exrensive suporasellar pituitary adenoma underwent resection via suprabital keyhole with endoscope-assisted microneurosurgery. Then the remaining tumor was removed with neuroendoscope via Ⅰand Ⅱ space of optic chiasma. The small bone flap was fixed with Ti clamp. Results After the tumor was removed with microneurosurgery, the remaining tumor was still found with endoscope in 7 cases. Remaining tumor was totally removed in 6 cases, almost removed in 3 cases. The vision improvement was found in 7 cases one week after surgery. In the other 2 cases, the vision remained unchanged. Follow-up was conducted in 6 cases for 6 to 22 months. Neuroradiological recovery of MRI with no recurrence of tumor was observed. No complication of incision was present. Conclusion Enough intra and extra-cranial space can be provided to operate via orbital roof approach to sellar tumors. Endoscope-assisted microneurosurgery can increase the total-resection and successful rate treatment for extensive suprasellar pituitary adenoma, reduce the possibility of complication, and pretect the function of brain from being injured. Fixation of small bone flap with Ti clamp is safe, easy and reliable.
