Objective To evaluate the clinical efficacy of endovascular embolization with detachable balloon, based on the characteristics of traumatic carotid-cavernous fistulae (TCCF), in treating TCCF. Methods The clinical data of 188 patients with TCCF, who had received endovascular embolization with detachable balloon via femoral artery access, were retrospectively analyzed. The risk factors for recurrence were statistically analyzed. Results Of the total 188 patients, complete cure after the first balloon embolization was obtained in 160, certain improvement of clinical symptoms was achieved in 22, and balloon embolization failed in 6, for whom other surgical options had to be carried out. Complications occurred in three patients. Recurrence was seen in 23 patients within the period from one day to 5 years after the treatment, and the recurrent lesion was successfully cured in all patients. Univariate analysis and chi square test or correction chi square test indicated that factors affecting postoperative recurrence were the use of multiple balloons for embolization and the presence of residual fistula after operation (P<0.05), while patient’s sex, age, duration of disease showed no statistically significant correlation with the recurrence (P>0.05). Multivariate logistic regression analysis revealed that the independent factors affecting recurrence included the number of used balloon≥2 (OR=7.80, 95%CI:2.28-26.73,P=0.001) and postoperative residual fistula that was observed immediately after the embolization (OR=10.46, 95%CI:2.99-36.50,P=0.000). Conclusion For the treatment of TCCF, transcatheter embolization with detachable balloon is minimally-invasive, safe and reliable with fewer complications, therefore, this technique should be regarded as the therapy of first choice. The use of multiple balloons and the presence of residual fistula observed immediately after the embolization procedure are the risk factors for recurrence. Other possible risk factors are still to be furtherstudied.

Objective A new mechanical thrombectomy instrument with preliminary clinical application were introduced. Methods Four cases (3 men and one woman; 61-71 years of age, mean age 66) consisting six legs with subacute or chronic occlusion of the femoropopliteal arteries having a course of 75 days to 10 months, were included in this study. All patients were treated with Straub Rotarex System (Straub Rotarex, patent pending. Straub medical, Wangs, Switzerland). Among them 2 cases were caused by atherosclerosis, 1 by emboli and 1 by diabetes mellitus. The lengths of the occluded segments were 3.8-56 cm. Results The thrombi were removed, and the arteries were undergone recanalization. The blood loss was low, amounting to 5-180 ml. Distal emboli formation in 3 legs were treated successfully by thrombsuction or thrombolysis. Conclusion Straub Rotarex System is a new safe and effective mechanical thrombectomy instrument.

ObjectiveTo explore efficacy,durability and possible impacts on life quality of carotid occlusion treatment to carotid cavernous fistula (CCF) patients.MethodsCCF patients since 2001 were retrospectively analyzed,the clinical features,2 weeks post procedure mRS score and ratio of carotid occlusion were recorded.Headache impact test (HIT-6) and Short form health survey(SF-36) were used to assess impact of sequelae in patients' daily life,by phone call,questionnaire and clinic recheck.Results Total 96 cases were studied composed of 81 direct CCF and 15 dural AVF.Thirty-two direct CCF cases underwent carotid occlusion during procedure and many ophthalmologic signs but visual impairment got recovery after 2 weeks,the mRS score less than 2 were revealed.The one year post operation HIT-6 score more than 50 was more likely found in carotid occlusion cases comparing with those preserved carotid artery while the 3 year SF-36 scores of carotid occlusion cases revealed inferior to those with patent artery,especially in body pain,general health and vitality subscales.ConclusionCarotid occlusion seems to be a feasible,effective and durable alternative for CCF treatment,but which could play a negative role on quality of patients' life in the long run.

Background and purpose: Epithelial ovarian carcinoma is the most malignant tumor in female reproductive system because of its resistance to chemotherapy. Fructose-1, 6-bisphosphatase (FBP1) is a rate-limiting enzyme in gluconeogenesis used to catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate and inorganic phosphate, thereby inhibiting the effect of glycolysis in tumor cells. This study aimed to investigate the association between the expression of FBP1 and chemosensitivity. Methods: The expression level of FBP1 in ovarian cancer patients was measured by immunohistochemistry. Results: According to the results of immunohistochemistry in 209 ovarian carcinoma specimens, the percentage of positive FBP1 expression was about 49.3% (103/209). Loss of FBP1 was a negative factor of survival (42.6 months vs 62.1 months, P=0.003). Besides, patients who were sensitive to chemotherapy displayed significantly higher scores of FBP1 expression than patients who were resistant to therapy (P=0.007). Conclusion: The rate-limiting enzyme FBP1 in gluconeogenesis can be used as a biomarker for predicting the chemoresistance and prognosis of ovarian cancer patients.

Objective To explore the safety and efficacy of the Wingspan stenting of basilar artery atherosclerosis stenosis though the analysis of single center massive clinical data. Methods Ninety one consecutive patients received Wingspan stenting because of basilar artery stenosis in our center from July 2007 to April 2013. The patients were classified into three groups:early term (n=30), middle term (n=30), and late term (n=31) according to the operation time in our center. The basic clinical data and the factors which may affect the ischemic events were retrospectively analysed, t test and Chi?Square test were used to analyze the factors related to the periprocedural ischemic complications. Results All of patients were stented successfully and the technical success rate was 100%(91/91). The mean stenosis was reduced from (82.2 ± 5.8)% to (15.9 ± 5.7)%; strokes or death happened in 13 cases within 30 days, including perforator stroke in 8 patients(8.8%, 8/91), thrombosis in 4 patients(4.4%, 4/91), subarachnoid hemo rrhage in 1 patient(1.1%, 1/91), 2 patients with disabling or fatal strokes. Lesions involving in the middle segment of basal artery (P=0.049), long?segment disease (P=0.002), severe stenosis (P=0.001) may be a risk factor affecting perioperative ischemic stroke, and the surgeons' surgical technique was not risk factors for ischemic complications (P=1.000). Seventy seven patients (84.6%, 77/91) had the clinical follow?up and the mean follow?up period was (31.3±15.1) months. Four patients suffered from posterior circulation strokes during the clinical follow?up , one of them (1.3%, 1/77) had disabling stroke, another 3 patients (3.9%, 3/77) suffered from TIA. The 2?year accumulate probability of stroke (any stroke or death within 30 days and stroke in the territory of the qualifying artery beyond 30 days)was 16%(95%CI, 8.2%to 23.8%). Forty six patients had the imaging follow?up and the mean follow?up period was(9.5±8.3)months, 6 patients(13.0%,6/46) had in?stent restenosis (ISR) and 2/6 patient had the symptomatic ISR. Conclusions The stroke or death rate of symptomatic basilar atherosclerosis Wingspan stenting within 30 days is high, but the disabling or fatal stroke rate is low. The middle segment of basilar artery involved, the long stenosis, the severe atherosclerosis may be the factors related to the periprocedural ischemic strokes. The incidence of disabling or fatal strokes was low following Wingspan stenting.
