目的:介绍一种自制的Matas试验架,探讨其临床应用效果。方法:介绍Matas试验架的制作和使用方法。并对10例颈动脉体瘤、4例巨大海绵窦动脉瘤、5例外伤性颈内动脉海绵窦瘘患者进行颈动脉压迫耐受训练。通过数字减影血管造影(DSA)和经颅多普勒(TCD)检查,了解大脑动脉及Willis环侧支循环的建立和代偿情况。结果:DSA和TCD显示大脑动脉及Willis环侧支循环的建立和代偿情况良好。19例患者均实施手术治疗和介入治疗,无一例发生并发症。结论:使用自制Matas试验架来进行颈动脉压迫训练,以其定位准确、压迫可靠、稳定性好、效果确切等优点,为成功手术提供了精确的术前评估和耐受训练。
ObjectiveTo understand risk factors of abdominal aortic aneurysm (AAA) rupture and the latest progress.MethodThe domestic and foreign related literatures on risk factors affecting AAA rupture were retrieved and reviewed.ResultsBesides some definite risk factors of AAA rupture, including age, gender, hypertension, smoking, family history, complications (such as diabetes mellitus, hypertension, dyslipidemia, etc.), the biomechanical factor was the crucial factor of AAA rupture, including the aortic compliance, aortic wall peak value of pressure, aortic wall calcification, and hemodynamics. The latest imaging methods such as the high resolution ultrasound, function and molecular imaging, and phase contrast magnetic resonance imaging could provide technical supports for the prediction of AAA rupture.ConclusionsThere are many risk factors affecting AAA rupture. Clinicians might prevent and make individualize treatment for AAA rupture according to its risk factors, and risks of AAA rupture could be more accurately assessed with help of new medical imaging examination.
ObjectiveTo explore the progresses of diagnosis and treatment for endoleaks after endovascular repair of abdominal aortic aneurysm (EVAR). MethodsThe literatures on studying the classification, diagnosis and management, risk factor, and treatment for the endoleaks after EVAR were reviewed and analyzed. ResultsEndoleak was a common and particular complication after EVAR and its represented persistence meant failure of the EVAR treatment. Accurate detection and classification were essential for the proper management and the treatment method for the endoleak was determined by the different source. Type Ⅰ and type Ⅲ endoleak required urgent treatment， type Ⅱ and type Ⅴ were considered less urgently but may be observed continuously. A variety of techniques including extension endografts or cuff, balloon angioplasty, bare stents, and a combination of transvascular and direct sac puncture embolization techniques were allowed to treat the vast majority of these endoleaks. ConclusionsEndoleak after EVAR is still the main clinical problem to be solved. The characters of endoleak still are not fully revealed. The diagnosis and treatment remained equivocal, which requires further study.
目的:探讨开颅夹闭和血管内栓塞治疗颅内动脉瘤的效果比较及并发症。方法:从2003～2008年近五年来我院收治的颅内动脉瘤54例,其中开颅夹闭24例(Hunt Hess分级Ⅰ～Ⅱ级20例,Ⅲ级2例,Ⅳ级2例),共26个动脉瘤。血管内栓塞30例(HuntHess分级Ⅰ～Ⅱ级23例,Ⅲ级5例,Ⅳ级2例),共31个动脉瘤。临床结果按GOS进行评价。结果:两组的良好率、并发症及死亡率无显著差别(Pgt;0.05)。随访平均12月,Ⅰ～Ⅱ级动脉瘤患者治疗良好率为100.0％(43/43),并发症发生率为4.7％(2/43),Ⅲ～Ⅳ级者分别为18.2％(2/11)和90.9％(10/11),两者相差显著(Plt;0.05)。结论:开颅夹闭和血管内栓塞治疗颅内动脉瘤,二者疗效相仿,各有优缺点。动脉瘤患者病情级别越高,治疗效果越差。
目的:探讨彩色多普勒超声在诊断冠状动脉造影术后引发的医源损伤性假性动脉瘤的临床价值。方法: 经股动脉穿刺,行冠状动脉造影术而发生的股动脉假性动脉瘤共39例,所有患者都采用高频彩色多普勒诊断仪,对动脉瘤的二维超声图像、彩色多普勒图像及脉冲多普勒图像进行分析。结果: 39例假性动脉瘤患者在穿刺部位动脉的一侧均显示一搏动性无回声区或混合性低回声区;彩色多普勒显示无回声区内呈涡流或旋转样血流信号,表现为一半红色一半蓝色;脉冲多普勒显示典型的双期双向频谱。39例假性动脉瘤彩色多普勒超声诊断完全明确。其中32例在彩色多普勒超声监控下行人工加压包扎修复。7例经血管外科手术修补治疗。结论: 彩色多普勒超声在诊断冠状动脉造影术后造成的医源损伤性假性动脉瘤,在观察动脉瘤的大小、形态、瘤体的结构,判断来源动脉破口定位上准确、简便、无创,且可在超声引导下行安全无创治疗,可作为该病诊断及治疗的首选方法。
