Objective To explore the near-term therapeutic effect and long-term result of stereotactie surgery in treatment of moderate hypertensive intraeerebral hemorrhage and discuss related problems of the surgery.Methods 60 cases of moderate hypertensive intracerebral hemorrhage were divided into two groups at random.30 cases treated by stereotactie surgery,the others treated by nonsurgical method, the near-term rebleeding rate, mortality rate and longterm living quality of the two groups were analyzed and compared.Results There were no statistical differences in rebleeding rate and mortality rate between the two groups( all P >0.05 ).The long-term result indicated that there was statistical difference in GOS grades between the two groups( P <0.05).The surgical group had better result than nonsurgical group.Conclusion The patients suffered for moderate hypertensive intracerebral hemorrhage treated by stereotsefic surgery had better long-term therapeutic effect than those treated by nonsurgical method.

Objective To compare the clinical efficacy of transdorsal-to-plantar (TDP) or transplantar-to-dorsal (TPD) retrograde endovascular angioplasty in treating below-the-knee arterial occlusion diseases, and to compare it with conventional anterograde endovascular angioplasty. Methods A total of 96 patients with below-the-knee arterial occlusion diseases (112 diseased lower extremities in total), who were admitted to authors’ hospital during the period from Oct. 2009 to July 2011 to receive conventional anterograde endovascular angioplasty, were enrolled in this study. The clinical data were retrospectively analyzed. Among the 112 diseased lower extremities, conventional anterograde endovascular angioplasty failed in 27, and TDP or TPD retrograde endovascular angioplasty had to be carried out. A total of 71 patients (85 diseased lower limbs) were successfully treated with conventional anterograde endovascular angioplasty (routine group), while 20 patients (22 diseased lower limbs) were successfully treated with retrograde endovascular angioplasty (retrograde group). The preoperative ankle-brachial index(ABI), the coronary angiography-based thrombolysis in myocardial infarction (TIMI) flow score, the dorsal or plantar arterial pulse score, the postoperative limb salvage rate and target vessel patency rate were calculated, and the results were compared between the two groups. Results The technical success rate in the retrograde group and the routine group was 75.9% and 74.0%respectively (P>0.05). Preoperative ABI value of the retrograde group and the routine group was 0.55± 0.21 and 0.56±0.14 respectively, after the treatment which increased to 0.93±0.19 and 0.89±0.18 respectively (P>0.05). Preoperative TIMI score of the retrograde group and the routine group was 0.1 ±0.5 and 0.8 ±0.8 respectively, which significantly increased to 2.5±0.6 and 1.8±0.8 respectively (P<0.000 1). In the retrograde group, the blood flow perfusion of the distal foot tissue was improved. The primary target vessel patency rate at 12 months and 24 months after the treatment in the retrograde group and the routine group were 63.6%(14/22), 45.5%(10/22) and 52.9%(45/85), 37.6%(32/85) respectively (P>0.05). Twenty-four months after endovascular angioplasty Kaplan-Meier analysis indicated that the limb salvage rate of the retrograde group and the routine group was 95.5%and 96.5%respectively (P>0.05). Conclusion Compared with conventional anterograde endovascular angioplasty for the treatment of below-the-knee arterial occlusion diseases, retrograde endovascular angioplasty via TDP or TPD path can immediately improve the blood flow with obvious improvement of ABI score, primary target vessel patency rate as well as the limb salvage rate. Therefore, retrograde endovascular angioplasty should be regarded as an effective supplementary technique when anterograde angioplasty fails.

Objective To report our experiences in the treatment of recurrent intracranial aneurysms with re-coiling or covered stents.Methods A total of 291 patients with 305 intracranial aneurysms were treated with detachable coils.and 41(28.9%)of 142 patients with aneurysms in the intemal carotid artery had a recurrent aneurysm during the follow-up period.For this study,31 recurrent aneurysms in 31 patients who had angiograms within 6 months following retreatment with detachable coils(group A,n=20)or covered stents(group B.n=11)were analysed.Aneurysms were categorised as complete or incomplete occlusion via angiographic assessment and graded as full recovery,improvement,no change or deterioration via clinical assessment.Data regarding technical success,initial and final angiographic results,final clinical outcome were collected and analysed postoperatively.Results Coil embolisation and covered stent placement.were technically successful in all recurrent aneurysms.The initial angiographic results showed complete occlusion in 11 patients(55%)in group A and in eight(72.7%)in group B(P=0.452),and the final angiographic results exhibited complete occlusion in 10 patients(50%)in group A and in 11(100%)in group B(P=0.005).There were no significant differences in technique success or final clinical outcome between the two groups.Conclusions Recurrent aneurysms after coiling can be successfully treated and occluded with re-coiling or covered stent placement.However,covered stents seem to be more effective than re-coiling with regard to complete occlusion of recurrent aneurysms.
