A型主动脉夹层术后脑部并发症危险因素分析

Ohjective Retrospectively analyze the risk factors of neurological complications of 160 patients with type A aortic dissection who underwent surgical repalr using cerebral peffusion under deep hypothemia circulatory arrest and to sum the experience of cerebral protection. Methods From January 2004 to January 2006,160 patients with type A dissection underwent surgical repair with cerebral perfusion and DHCA. There were 106 male petients ond 54 female with age from 17 to 76 years old [mean, (56±13) years old]. Antegrade selective cerebral perfusion (SCP) through axillary artery was performad for 131 patients and retrograde cerebra l perfusion (RCP) from superior caval vein for 29 patients. Emergency surgery was perfomed in 83(51.8%) patients who were suf- fered from acute type A dissection, and the others were chronic elective surgery. All the factors underwent univariaare and multivariate analysis. Results Mean cardionpulmonary bypass (CPB) duration was (188± 57) minutes and mean cerebral perfusion time was (36±16) minuties. Sixteen patieats died in hospital and the in-hospital mortality was 10.0%. Deaths were due to multiple argan fail- ure in 9 patients, respiratory failure in 2, low cardiac output syndrome in 2, bloeding in 2, aeptic shock in 1. Postoperative respirato- ry dysfunction were observed in 22 (13.7%) parley. Postoperative renal failure happened in 20(12.5%) patients. Postoperative low cardiac output appeared in 8(5.0%) patients. Penmanent neurological deficits occurred in 8(5.0%) petients. The preopertive renal dysfunction (OR= 11.71, P=0.005), coronary artery disease (OR= 7.35, P =0.035), eet～ml vasenlar disease (OR= 13.39, P=0.021) and postoperative low cardinc ontput (OR=22.21, P=0.008) were found robe the relative risk factor. Tran- sient neurological deficts(TND) were noted in 32 patients. Over seventy years old (OR=1.17, P=0.042) was the independent risk predictors. Surgery procedures, CPB time, cross-clamp time, cerebral perfusion time, methods for cerebral perfusion, filtration used or not, the esophageal temperature and the bladder temperature and the hematocrit (HCT) during CA did not significantly influence the cerebral outcomes.Conclusion In our experience, cerebral perfusion duration within the limits of safe time and the methods of cerebral perfusion did not influence the neurological outcomes which depended on the severity of the underlying disease and on the function of end-organs. Protection of all the end-organs would be helpful to the cerebral protection.

Emergency percutaneous thoracic endovascular aortic repair for patients with traumatic thoracic aortic blunt injury: A single center experience

Purpose:To analyze the efficacy and outcome of percutaneous thoracic endovascular aortic repair(TEVAR)in patients with traumatic blunt aortic injury in our single-center.Methods:From January 2014 to December 2018,a total of 89 patients with traumatic blunt aortic injuries were treated with emergency TEVAR in our center.Their clinical data such as demographics,operative details and postprocedure outcomes were analyzed retrospectively in this study using SPSS 20 software.Continuous variables were expressed as mean and standard deviation or median and interquartile range.Categorical variables are expressed as the numbers and percentages of patients.Results:The median age of the patients was 37 years,and 76(85.4%)were males.All the patients were involved in violent accidents and combined with associated injuries.Two patients died while awaiting the operations and 87 patients underwent emergency percutaneous TEVAR,with a 100%technique success.The mean time interval from admission to operating room was(90.1±18.7)min,and the mean procedure time was(54.6±11.9)min.Eighty(92.0%)patients were operated on under local anesthesia,while other 7(8.0%)patients were under general anesthesia.Two cases underwent open repair of the femoral arteries because of the pseudoaneurysm formation of the access vessels.A total of 98 aortic covered stent grafts were deployed,of which 11 patients used two stent grafts(all in dissection cases).The length of the stent was(177.5±24.6)mm.The horizontal diameter of aorta arch at the proximal left subclavian artery ostium was(24.9±2.4)mm,the proximal diameter of the covered stent was(30.5±2.6)mm,and the oversize rate of proximal site was(22.7±4.0)%.The proximal landing zone length was(14.1±5.5)mm.The left subclavian artery ostium was completely covered in 5 patients and partially covered in 32 patients.No blood flow reconstruction was performed.The overall aortic-related mortality was 2.25%(2/89).Among 87 patients,the median follow-up time was 24 months.Postoperative computed tomography angiography scans demonstrated no residual pseudoaneurysm,hematoma or endoleak.One patient complained of mild left upper limb weakness during follow-up due to left subclavian artery occlusion.Neither late death,nor neurological or other complications occurred.Conclusion:Emergency percutaneous endovascular repair is a less invasive and effective approach for the treatment of traumatic blunt aortic injuries.Long-term results remain to be further followed.     

胫骨干骨折的手术治疗对策

目的：明确不同固定器械在胫骨干不同骨折类型固定中的特点，以指导临床应用。方法：68例胫骨干骨折，行加压钢板螺钉、交锁髓内钉、单侧外固定架固定后，作临床疗效分析。结果：加压钢板固定组42例，感染5例，骨不连1例，平均愈合时间3．8个月；交锁髓内钉固定组13例，无感染及骨不连，平均愈合时间5．4个月；单侧外固定架组13例，骨不连1例，踝关节背伸受限3例，平均愈合时间4．5个月。结论：胫骨骨折交锁髓内钉固定并发症少，功能恢复好，适用范围广，但要注意及时进行动力加压。加压钢板及外固定架固定应选择各自的最佳适应证，以达到理想的疗效。
