Objective To evaluate the mid- and long-term radiological outcomes of cerebral aneurysms with GDCs embolization.Methods One hundred and sixty-two patients with 173 aneurysms embolized with GDCs underwent angiographic follow-up from 1 to 54 months post-operatively and were retrospectively reviewed. Three neuro-radiologists reviewed each angiogram and made a comparison between initial and follow-up angiograms. Morphological outcomes were evaluated as follows: unchanged; progressive thrombosis; and re-opening or re-growth. Results Of 173 aneurysms with GDC embolization, 142 aneutysms had total or nearly total occlusion, 23 subtotal occlusion and 8 partial occlusion shown on initial angiograms. The incidence of re-opening was 17.1% (13/76) in less than 3 months, and 6.2% (6/97) between 3 and 6 months postoperatively. Four aneurysms showed recurrency(2.3%) on second follow-up angiography in one year after procedure and one-year cumulative recurrent rate was 13.3% of 56 aneurysms with the third follow-up angiography in the post-operation period of 12 to 54 months, four showed a little enlargement and the cmnulative recurrent rate so far was 20.2% (35/173). Conclusions The direct and main causes for aneurysmal recurrence are incomplete and loosening packing. The first angiographic follow-up is recommended to be performed at 3 months or earlier after the procedure, especially in aneurysms with initial incomplete occlusion. Re-treatment with balloon- or stent-assisted coil embolization is recommended in re-opening aneurysms. (J Intervent Radiol,2005,14:472-479)

Objective To investigate the impact of diabetes on coronary artery bypass grafting (CABG)in peroperative patients. Methods Clinical data of 692 CABG patients were collected retrospectively from Sep. 2006 to Jul. 2010. The CABG patients were divided into diabetic group (n = 276) and nondiabetic group (n = 416) according to with the status of diabetes or not before operation. Blood glucose was dynamicaly monitored and treated with insulin to control blood glucose in perioperativeperiod. The postoperative effect,perioperative complication and inhospital case fatality and their relationship with diabetes were analyzed using univariate analysis. Results No significant differences were found regarding the incision complications (5. 8%vs. 4. 3 % , P > 0. 05). The volume of blood transfusion was (890. 7 ± 520. 6) ml in the diabetes group, which was not significantly different from that of (825. 2 ±518. 4)mlin the non-diabetes group (P>0. 05). No significant difference was found on cardiac arrhythmia (13.0% vs. 13. 5%),renal function insufficient (5. 1% vs. 2.4%)and case fatality (2. 9% and 1. 9%) between the diabetes and non-diabetes group (Ps >0. 05). In the diabetes group and non-diabetes group, the duration of IABP (3.7 ± 1. 6) d vs (3.5 ± 1.6)d, use of ventilator (2. 6 ± 1.9)d vs. (2. 4±1.5)d were not sigfnificantly different (Ps >0.05). The length of hospital stay and cost were (22. 0 ±8. 8)d and (8. 11 ±2. 40) thousand RMB in the diabetes group, which were significantly higher than that of (20. 6 ±7. 6)d and (7. 63 ±2. 20) thousand RMB in the non-diabeties group (t =2. 22 and 2. 71 ,Ps <0.05) . Conclusion There are no significant differences in the operative case fatality and complications between patients with diabetes and without nondiabetes. However,diabetes increases hospital stay and expense.

Objective To present our single-center experience in treating traumatic direct carotidcavemous fistulas (TDCCFs)by using detachable balloon,coil and Willis covered stent via arterial route.Methods During the last five years,transarterial endovascular treatment by using detachable balloon,coil and Willis covered stent was performed in fifty-one consecutive patients of traumatic direct carotid-cavernous fistulas.with a total of 54 TDCCFs.The detachable balloon was the material of first choice,while Willis covered stents and coils were regarded as the back-up materials.A clinical and angiographic follow-up for 348 months (mean 20.8 months) was conducted to evaluate the arterial patency and the stability of embolization.The clinical data were retrospectively analyzed.Results By using the detachable balloon alone via transarterial route.85%TDCCFs were successfully treated with good preservation of ICA.A total of 98% TDCCFs in this study were successfully treated by using detachable balloon,coil and/or Willis coveted stent,the fistulas became occluded,and ICAs were preserved except one patient.Forty TDCCFs were treated with detachable balloons alone,two TDCCFs with the Willis covered stent alone,and one DCCF with coils alone.Eight TDCCFs were treated with detachable balloons together with Willis covered stent.Of these eight TDCCFs,two were treated with a single session,three were treated with detachable halloons in combination with coils,and one had to receive Willis covered stent.Second and third times of endovascular treatment were needed in 12 TDCCFs.The TDCCF-rel(at)ed symptoms were gradually relived or improved within 1 day to 6 months after treatment,except for five patients who suffered from ipsilateral moderate visual loss or cranial nerve deficit.No perioperative complications.such as vessel rupture,distal embolization or new neurologic deficits,occurred.During the follow-up period lasting for six months,neither delayed neurologic or vascular complications nor recurrence of the lesions developed.Conclusion Via the transarterial route,using detachable balloon to occlude the fistula and at the same time to preserve ICA remains the optimal treatment for TDCCFs.When the standard treatment fails.various coils and the Willis covered stents can be used as an effective alternative or remedial tool in the treatment of TDCCFs,which can preserve ICA.Willis covered stent deployment seems to be an effective,safe,feasible and economical endovasculal treatment for TDCCF,but more clinical studies are needed before we can further clarify its specifications and indications.

BACKGROUNDAcute renal failure following coronary artery bypass grafting (CABG) surgery is associated with high morbidity and mortality. Approximately half of all patients who develop acute kidney injury (AKI) subsequently develop acute renal failure (ARF). The purpose of the study was to compare early transient changes in renal function within the first post-operative week following CABG in patients that were either off-pump or on-pump.
METHODSEight hundred and forty-nine consecutive patients with isolated CABG in a single institution between January 1990 and August 2006 were retrospectively analyzed, including 518 off-pump and 331 on-pump patients. A multivariate Logistic regression model was constructed to identify risk factors for the development of AKI.
RESULTSSixty-one off-pump patients and 63 on-pump patients developed AKI. Risk factors for the development of post-operative AKI included an ejection fraction > or =50% or < or =30%, a pulse pressure > or =60 mmHg, peripheral vascular disease, diabetes, emergent procedure, triple-vessel disease, body mass index, peri-operative and post-operative. intra-aortic balloon pumping, NYHA class III and IV, and cardiopulmonary bypass. An ejection fraction > or =50% and peri-operative and post-operative intra-aortic balloon pumping were protective (OR <1). Peak serum creatinine for post-operative AKI was noted 12 hours and 24 hours in the off-pump and on-pump patients, respectively. Serum creatinine kinetics revealed rapid recovery in the 24th to 48th hour (off-pump) and the 48th to 72nd hour (on-pump).
CONCLUSIONRenal protection strategies are indicated from general anesthesia induction until 48 and 72 hours post-operatively in off-pump and on-pump patients, respectively.
