Abstract：

Objective To explore the therapeutic effect of preoperative external hunbar drainage in Hunt and Hess grade Ⅰ～Ⅲ patients with subarachnoid hemorrhage ( SAH ) undergoing early surgery for intracranial aneurysms. Method The 101 cases of grade Ⅰ～Ⅲ patients according to the classification of Hunt and Hess with early surgical treatment were devided into preoperative external lumbar drainage group(47 cases) and postoperative external lumbar drainage group(54 cases).Outcome of patients with different external drainage of cerebrospinal fluid was analyzed. Results There was no case of aneurysm rebleeding could be associated with preoperative spinal drain placement. Tne incidences of intraoperative aneurysm rapture in preoperative external lumbar drainage group was 8. 5%,which was lower than 11. 1% in postoperative external lumbar drainage group. The incidences of symptomatic cerebral vasospasm and chronic hydrocephalus in preoperative external lumbar drainage group were 12. 8% and 12.8% ,which were lower than 20. 4% and 14. 8% in postoperative external lumbar drainage group. There all were not significant differences between the two groups. Conclusions Preoperative external lumbar drainage wont increase a risk of rebleeding for grade Ⅰ～Ⅲ patients with aneurysmal SAH undergoing early surg ery. Furthermore, it can decrease the incidences of symptomatic cerebral vasospasm and chronic hydrocephalus,which is a safe and useful method of removing bloody cerebrospinal fluid.     

Outcomes of early physiotherapy in patients with cerebral aneurysms treated by surgical clipping or endovascular embolization

Early physiotherapy was given to 124 patients with ruptured or unruptured cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients were divided into four groups according to their Hunt and Hess grade at admission and aneurysm treatment modality: Group 1,Hunt and Hess grade≤II and surgical clipping;Group 2,Hunt and Hess grade≤II and endovascular embolization;Group 3,Hunt and Hess grade≥III and surgical clipping;Group 4,Hunt and Hess grade≥III and endovascular embolization.Level of consciousness was evaluated using the Glasgow Coma Scale,functional status using the Glasgow Outcome Scale,level of the mobility using the Mobility Scale for acute stroke patients,and independence in activities of daily living using the Barthel Index.After early physiotherapy,the level of consciousness and functional status improved significantly in Groups 1,3,and 4;mobility improved significantly in all groups;and independence in activities of daily living improved significantly in Groups 1 and 3.At discharge, Groups 1 and 2 had better functional status than Groups 3 and 4.Level of consciousness,functional status,mobility and independence in activities of daily living improved after early physiotherapy. These findings suggest that early physiotherapy improved the prognosis of patients with cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients with a worse clinical status at presentation had a poorer functional status at discharge.The outcome of physiotherapy was not affected by whether surgical clipping or endovascular embolization was chosen for treatment of the aneurysm.

Abstract：

Objective To study the risk factors of intraprocedural re-rupture (IPR) of ruptured intracranial aneurysms, and the emergency management on this event and its efficacy. Methods The clinical data of 236 patients with ruptured intracranial aneurysms, admitted to our hospital from 2005 to 2009 and treated with embolization, were retrospectively analyzed; non-conditional logistic regression analysis was performed to analyze the risk factors of IPR of ruptured intracranial aneurysms. And the emergency management of IPR and its efficacy were concluded in 16 patients with IPR. Results The risk factors of IPR of ruptured intracranial aneurysms included small aneurysms with a diameter smaller than or equaling to 3.0 mm (OR=6.353, 95% CI: 1.266-31.894, P=0.025), aneurysms at distal part of Al and M1 segment of the anterior cerebral artery or middle cerebral artery (OR=35.449, 95% CI:3.053-411.642, P=0.004), atherosclerosis (OR=5.961, 95% CI: 1.215-29.260, P=0.028), mild vasospasm (OR=13.048, 95% CI: 1.220-139.574, P=0.034) and severe vasospasm (OR=14.826, 95% CI:1.871-117.488, P=0.011). Immediate reversal of heparin anticoagulation with protamine sulfate and rapid completion of coiling were performed in 16 patients (6.78%) occurred IPR. Emergent external ventricular drainage was performed in 12 patients having above Hunt-Hess grade Ⅲ:6 patients died; 1 was under persistent vegetative state and 9 fully recovered. Conclusion Small aneurysms, atherosclerosis,cerebral vasospasm and aneurysms at the distal part of Al or M1 segment may easily lead to IPR of ruptured intracranial aneurysms. Rapid completion of coiling combined with immediate reversal of heparin anticoagulation, and emergent external ventricular drainage performed in severe patients are confirmed to be the keys, which can decrease the death rate and improve the prognosis.

Objective To evaluate the safety, efficacy and feasibility of endovascular interventional therapeutic techniques for ruptured hemorrhagic intracranial aneurysms in highland in Tibet. Methods Retrospectively analyzed the therapeutic effects of endovascular interventional treatment for ruptured hemorrhagic intracranial aneurysms in 8 cases in highland in Tibet 8 cases were performed DSA for accurate diagnosis and individualized endovascular interventional treatment were undergone according to the feature of the aneurysms; coiling in 5 cases, coiling with assistance of stent in 2 and pure stenting in 1. Results Among the 8 cases complete embolization was gained in 6 and hypo - complete embolization in 1. DSA review during procedure showed the image of aneurysm disappeared in 7 cases and retention of contrast agent inside the aneurysm in the case which was purely stented. Contralateral hemiplegia of limbs which muscle strength was 0 grade occurred in 1 case with wide - necked aneurysm treated by coiling with stent assistance after procedure. After the intensive treatment of antiplatelet, anticoagulation and to improve microcirculation, the muscle strength recovered to Ⅴ grade in the lower limb and near Ⅴ grade in the upper limb. After procedure except 1 case whose Hunt & Hess grade was in Ⅵ and GCS was 4 improved Hunt & Hess grade to Ⅲ and GCS to 4 because of secondary severe hydrocephalus, the other cases were all well recovered. During 1 to 5 months following - up of outpatient no re - hemorrhagic or ischemic event occurred. Conclusions Endovascular interventional treatment is safe, mini- invasive, effective and feasible for ruptured hemorrhagic intracranial aneurysms in highland in Tibet, but the peri - operative management was highland characteristic.     

Is type I alpha 2 collagen gene responsible for intracranial aneurysm in Northeast China?

In this study, we investigated whether a single nucleotide polymorphism (rs42524 G > C) in the type Ⅰ alpha 2 collagen gene was associated with sporadic ruptured intracranial aneurysm or its clinical characteristics in patients from Northeast China. Genotyping of the rs42524 G > C polymorphism was carried out using a polymerase chain reaction-restriction fragment length polymorphism assay. The data showed that the frequency of the rs42524 GC + CC genotype was significantly higher than the GG genotype among intracranial aneurysm patients whose Hunt and Hess grading scale was > 3. In addition, the rs42524 G > C genotype was found to have a statistically significant association with intracranial aneurysm risk. These findings indicate that the type Ⅰ alpha 2 collagen gene gene may be involved in a predisposition to intracranial aneurysm in the Northeast Chinese population. Crucially, the rs42524 C allele may be an important risk factor for increased severity of the condition in patients with ruptured intracranial aneurysms.

Abstract：

Objective To study the clinical characteristics and microsurgical skills of intracranial mirror-image aneurysm. Methods The clinical data and post-operative outcomes of 17 patients with 36 intracranial mirror-image aneurysms who underwent microsurgical operation were analyzed retrospectively. Results Thirty-five aneurysms were clipped directly and 1 did not give any treatment. One-time surgery was performed in 9 patients and 20 aneurysms were clipped. Two-stage operation was performed in the other 7 patients: 7 aneurysms were clipped in the first surgery and 7 in the second one. One patient received aneurysm clipping only in one side of the brain. CTA was performed again on 11 patients, noting that residual aneurysm neck of the 2 aneurysms existed in 23 clipped aneurysms, that the other aneurysms disappeared, and that the parent arteries were clear. GOS indicated that good surgical outcomes were achieved in 12 patients, light disability in 4 and severe disability in 1.Conclusion The surgical outcomes of intracranial mirror-image aneurysm performed microsurgical operation are predominance. Criminal aneurysms should be determined correctly and clipped firstly; and according to the sites and grades of the aneurysms and the patient's condition, good outcomes can be achieved by choosing one-time operation or two-stage operation.

Operative strategy of complex internal carotid artery- posterior communicating artery aneurysms Defensive effect on perioperative nerve injury

BACKGROUND: The two problems in treating intracranial aneurysm are the vascular reconstruction and brain protection, especially for complex internal carotid artery-posterior communicating artery (ICA-PComA) aneurysms. OBJECTIVE: To analyze the anatomic features and operative technique of complex ICA-PComA aneurysms, and investigate how to better protect the brain tissue. DESIGN: A retrospective case analysis. SETTING: Department of Neurosurgery, Dalian Central Hospital. PARTICIPANTS: Totally 154 inpatients with ICA-PComA aneurysms were selected from the Department of Neurosurgery, Dalian Central Hospital from January 1998 to December 2006, including 19 cases (12.3%) of complex ICA-PComA aneurysms, 8 males and 11 females, 38–67 years of age. Informed contents for surgery and observation were obtained from all the patients or their relatives. METHODS: The clinical manifestations, including initial symptoms and Hunt&Hess grading, were observed. Corresponding strategies were selected for different types of ICA-PComA aneurysms. The patients were followed up at 3 months postoperatively. According to the results of Glasgow scoring, the curative effects were classified as good (4–5 points), bad (2–3 points) and dead (1 point). The results at discharge were taken as early results, whereas the follow-up results as late results. MAIN OUTCOME MEASURES: Clinical manifestations and curative effects of the patients. RESULTS: All the 19 patients with ICA-PComA were involved in the analysis of results. For clinical manifestations, the initial symptoms were subarachnoid hemorrhage (n =15), paralysis of oculomotor nerve (n =3), and occasional attack (n =1); The Hunt&Hess grading was grade Ⅰ in 4 cases, grade Ⅱ in 6 cases, grade Ⅲ in 6 cases, grade Ⅳ in 2 cases, and grade Ⅴ in 1 case. The curative effects were that aneurysm breakage and bleeding occurred in 6 cases perioperatively, uncomplete clipping of aneurysm in 2 cases and constriction of parent artery in 1 case. The complications were nervous and ischemic ones. The early outcome was good in 12 cases and bad in 7 cases, no one died. The late outcome was good in 17 cases and bad in 2 cases. CONCLUSION: Complex ICA-PComA aneurysm is a particular aneurysm, thus different operative strategies should be adopted according to the conditions to improve the operative outcome and reduce ischemic and nervous injuries.

Risk factors and outcome in 100 patients with aneurysmal subarachnoid hemorrhage

OBJECTIVE: Clinical and surgical outcome of patients with subarachnoid hemorrhage (SAH) due to ruptured aneurysm were assessed in comparison to pre-operative data and risk factors such as previous medical history, clinical presenting condition, CT findings and site of bleeding. METHODS: We evaluated 100 consecutive patients with aneurysmal SAH. Gender, color, history of hypertension, smoking habit, site and size of aneurysm, admittance and before surgery Hunt Hess scale, need for cerebro-spinal fluid shunt, presence of complications during the surgical procedure, Glasgow Outcome Scale, presence of vasospasm and of rebleeding were assessed and these data matched to outcome. For statistical analysis, we applied the chi-squared test or Fisher's test using the pondered kappa coefficient. Kruskal-Wallis test was used for comparison of continue variables. Tendency of proportion was analyzed through Cochran-Armitage test. Significance level adopted was 5%. RESULTS: Patients studied were mainly white, female, without previous history of hypertension and non-smokers. Upon hospital admittance, grade 2 of Hunt-Hess scale was most frequently observed (34%), while grade 3 of Fisher scale was the most prevalent. Single aneurysms were most frequent at anterior circulation, between 12 and 24 mm. The most frequent Glasgow Outcome Scale observed was 5 (60%). Hunt Hess upon the moment of surgery and presence of complications during surgical procedure showed positive correlation with clinical outcome (p=0.00002 and p=0.001, respectively). Other variables were not significantly correlated to prognosis. Tendency of proportion was observed between Hunt-Hess scale and Fisher scale. CONCLUSION: Among variables such as epidemiological data, previous medical history and presenting conditions of patients with ruptured aneurysms, the Hunt-Hess scale upon the moment of surgery and the presence of surgical adversities are statistically related to degree of disability.
