Keyhole Approach Endoscopic Surgery versus Stereotactic Aspiration plus Urokinase in Treating Basal Ganglia Hypertensive Intracerebral Hemorrhage / 中国医学科学院学报

To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated. Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all 0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all >0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all >0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(=0.413). Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

Relationship of sphenoid intersinus septa with transsphenoidal resection of sellar area tumor / 中华神经医学杂志

Objective To study the relationship of sphenoidal intersinus septa with transsphenoidal resection of sellar area tumor. Methods The pre-operative MRI and CT images of the sphenoid intersinus septa and its importance in transsphenoidal resection of sellar area tumor were studied in 107 patients, admitted to our hospital from January 2008 to December 2010. The amounts, locations, anatomic specialties of the septa and its relationships with the floor of selle, the internal carotid artery canals and the tumors were analyzed to guide the operative procedures during the operation. Results Total removal of the tumors in seller region was obtained in 67 patients, subtotal removal in 21 and partial removal in 19. According to the MRI and CT images of the sphenoid intersinus septa, the location of the tumor and the carotid artery in 47 patients were quickly determined; complex sphenoid intersinus septa was noted in 11 patients, and the relation of sellar floor with the septa was quickly determined and the scope and direction of removal were determined too. Rupture of the internal carotid artery occurred in 1 patient, and damages of the cavernous sinuses occurred in 4. Conclusion Careful study of the pre-operative MRI or CT images of the sphenoidal intersinus septa and its relationship with the floor of seller, the internal carotid artery and the tumor will assure the transspenoidal surgery more precisely and safely, and the complication can be efficiently prevented and decreased.

Microsurgical treatment of multiple intracranial aneurysms / 中华神经医学杂志

Objective To explore the problems of microsurgical treatment of multiple intracranial aneurysms with regard to the indications,surgical timing,operative approaches and the prevention of complications, and improve their diagnoses and treatments. Methods We retrospectively reviewed the data of 33 patients with multiple intracranial aneurysms admitted to our hospital from Jan.2000 to Dec.2008 and their clinical manifestations,imaging features and microsurgical treatments were summarized. Results In the 33 cases of multiple intracranial aneurysms,the male-to-female sex ratio was 1:1.75 and the average age at onset of symptoms was 56.52.Twenty-four patients showed good postoperative prognosis(Glasgow Outcome Scale IV-V) with 2 deaths.Conclusion Individual treatment should be adopted in the treatment of differently localized multiple intracranial aneurysms with different sizes and clinical classifications,and the utilization of temporary blockade and ultrasound during the operation can improve the therapeutic effects and reduce the postoperative complication rates.

Stereotactic surgery in treating intracranial cystic lesions / 中华神经医学杂志

Objective To explore the methods, efficacy and advantages ofstereotactic surgery.Methods A retrospective analysis of 29 consecutive patients with 37 lesions (mean age, 34.6 years),received surgery between Dec 2002 and Nov 2009, was performed. Histological findings showed 11 craniopharyngiomas, 5 cystic gliomas, 3 metastases and 10 cerebral abscesses. Eighteen patients underwent cyst aspiration by the Ommaya reservoir system combined with 32P endocavitary irradiation;median irradiation doses were 800 μCi. One was treated with aspiration and then radiotherapy only. Ten patients with cerebral abscesses received cystic drainage (8 cases) and aspiration (2 cases). Results No operative bleeding and death were found in this experiment. Follow up was performed for a median of 10.6 months (range, 1-60 months) and 4 were out of contact. All patients with craniopharyngiomas remained stable without recurrence after treatment; complete resolution was achieved in all patients with cerebral abscess; in the other 8 patients with tumors(12 lesions), 5 were under control of the symptoms for an average of 14 months and 3 (2 with metastases and 1 with glioblastoma) did not get improvement after the treatment. Two patients with craniopharyngioma experienced a transient slightly worsening of hypothalamic functions, including transient diabetes insipidus, low fever and vomit. Conclusion Stereotactic technique has its advantages in treating patients with cerebral abscess, craniopharyngiomas,metastatic tumors and gliomas that were small size, while it does not that effective in the cystic metastases that are in large size and difficult to control in a short term.
