Who should do endovascular repair of complex aortic aneurysms and how should they do them?

BackgroundCure of aneurysms which involve the aorta at the level of the visceral arteries and the thoracoabdominal segment remains a considerable surgical enterprise with a relatively high mortality and morbidity despite improvements of the surgical procedure and anesthetic technique. Fenestrated and branched endovascular stent grafts are currently available offering an attractive less invasive option especially for most frail patients. These grafts are relatively recent, technically more demanding to insert than the current stent graft for infrarenal aneurysm and besides, given the relative low frequency of the disease, they are much less used by practitioners. Thus, unconditional widespread of this sophisticated technique may not necessarily benefit patients.MethodsWe reviewed our experiences and articles regarding this concern, 1) who should perform this new technique and 2) in what kind of setting.ConclusionBased on the combined complexities of 1) patients selection, 2) proper planning and manufacturing of the graft, 3) the need for outstanding imaging and operating facilities, 4) and the required endovascular skill of physicians involved in the procedure, we feel that only highly specialized centers should be allowed to perform this complex procedure.     

前尿道代后尿道成形术治疗男性复杂性后尿道狭窄

目的探讨长段复杂性后尿道狭窄治疗新方法。方法采用分期前尿道代后尿道成形术治疗3例复杂性后尿道长段狭窄（6．5—10．0cm）患者。第一期行阴茎转位尿道端端吻合术，术后3—6个月行二期阴茎伸直、尿道会阴造口术，6个月后行第三期前尿道成形术（Johanson Ⅱ期尿道成形术）。结果例1术后排尿通畅，膀胱尿道造影检查示尿道通畅，双侧输尿管返流近消失，最大尿流率18．8ml／s，随访2年，最大尿流率18ml／s，无剩余尿。例2术后排尿通畅，最大尿流率19．5ml／s，无剩余尿，尿道扩张可顺利通过22F尿道探子。例3经会阴一耻骨联合径路行第一期阴茎转位尿道端端吻合术、尿道直肠瘘、尿道会阴瘘切除、修补术，术后尿道直肠瘘及尿道会阴瘘治愈，但因耻骨联合切口感染致吻合口狭窄，有待进一步治疗。结论分期前尿道代后尿道加前尿道重建方法是治疗男性长段复杂性尿道狭窄的有效方法。     

Nonconvulsive Status Epilepticus: High Incidence of Complex Partial Status

Nonconvulsive status epilepticus may be subdivided into generalized (absence) status and complex partial status. The latter is regarded as a rarity, whereas the former constitutes the dominant part of the hitherto reported cases. We report 10 consecutive cases of adult patients with nonconvulsive status epilepticus, all documented by ictal electroencephalographic (EEG) recordings. Five had a complex partial status; the origin of the complex partial status appeared to be frontal in four of these patients. Three had recurrent complex partial seizures with incomplete recovery between seizures, and two had more continuous symptoms. One of the latter exhibited neither motor phenomena nor automatisms. The effect of diazepam or clonazepam was immediate in all 10 cases though transient in eight. A lasting control of the status was not achieved in six patients until i.v. phenytoin was added. The difficulties in the differentiation between complex partial status and absence status despite ictal EEG recordings are discussed, illustrated by a case with seizure discharges of a focal onset which rapidly generalized. The study indicates that complex partial status may be more common and the clinical expressions of absence status more variable than hitherto recognized.     

Heubner回返动脉显微外科解剖及其临床应用

目的 :为前交通动脉复合体部位显微手术避免损伤Heubner回返动脉提供相关的应用解剖学资料。方法 :对经双侧椎动脉 (VA)、颈内动脉 (ICA)乳胶灌注的尸头标本 2 2例 ,按翼点入路方向 ,在手术显微镜下解剖观测 2 0例Heubner回返动脉的起点、管径、行径及其毗邻关系。 2例模拟手术操作。结果 :(1)本组观测到 4 3支回返动脉 ,其中 39支Heubher回返动脉 ;4支副Heubner回返动脉。 (2 )Heubner回返动脉 4 6 .5 % (2 0 / 4 3)起于A2 段 ,2 5 .6 % (11/ 4 3)起于A1段 ,2 7.9% (12 /4 3)起于前交通动脉 (ACOA)水平的大脑前动脉 (ACA)。 (3)Heubner回返动脉起点管径 :左侧 0 .81± 0 .2 1mm(0 .35～ 1.17mm) ;右侧 0 .84± 0 .2 6mm(0 .37～ 1.2 1mm)。 (4 )回返动脉发出后 ,与ACA反方向成锐角 ,沿A1上壁、外侧及后内侧 ,越过ICA两分叉 ,经大脑中动脉 (MCA)始段前面穿通入脑 ,少数回返动脉行走于前穿质 (APS)的后部。A1近端 3～ 5mm或中 1/ 3段穿通支少。结论 :在前交通动脉复合体部位手术时 ,A1近端 3～ 5mm或中 1/ 3段夹闭 ,并解剖寻找、剥离Heubner回返动脉 ,可避免损伤Heubner回返动脉及其它穿通支 ,最大限度减少术后并发症     

"分段切开,多重挂线术"治疗高位复杂性肛瘘临床研究

目的:观察"分段切开,多重挂线术"治疗高位复杂性肛瘘的临床疗效。方法:将60例高位复杂性肛瘘随机分为治疗组40例,采用"分段切开,多重挂线术";对照组20例,采用传统切开挂线术进行对比观察。结果:显示治疗组与对照组显愈率分别为95%和90%,无明显差异(P>0.05),但两组间的术后疼痛程度、创口愈合时间、肛门功能情况存在显著差异(P<0.05)。结论:在治疗高位复杂性肛瘘时,"分段切开,多重挂线术"与传统切开挂线术相比,具有手术操作简单,对组织损伤小,痛苦小、疗程短、肛门功能保护好等优点,该术式的应用,使得高位复杂性肛瘘治疗更加安全、有效。     

Pediatric intracranial aneurysms—clinical characteristics and outcome of surgical treatment

Object Intracranial aneurysms are rare in children and have different epidemiological, clinical, and morphological characteristics and outcome from those in adults. Materials and methods We analyzed demographic, clinical, radiologic features, treatment, and outcome in 55 patients <18 years of age, treated from Jan 1995 through December 2005. Results Intracranial aneurysms in children below 18 years constituted 4% of all intracranial aneurysms. Internal Carotid artery (ICA) bifurcation was the commonest location. About half of the aneurysms were complex. Three-fourth of the patients required surgical treatment. Two patients died, constituting 5% mortality. Two patients (5%) had poor outcome, whereas the majority (90%) had a favorable outcome. Conclusions Pediatric aneurysms have male predominance, higher incidence of clinical features of mass effect or seizures, high incidence of large, traumatic/mycotic aneurysms, associated illnesses and ICH/IVH and hydrocephalus, better Hunt and Hess grades at presentation, ICA bifurcation as the commonest site, and better outcome than their adult counterparts.     

A Management of Early CRPS I Caused by Ankle Sprain: A Case Report

Abstract:   We present a case of a 13-year-old boy who developed signs and symptoms of neuropathic pain/early Complex Regional Pain Syndrome (CRPS) Type I, formerly known as Reflex Sympathetic Dystrophy (RSD), after spraining his ankle while wrestling. Aggressive pain control, using medications and sympatholytic blocks, with physical therapy and rehabilitation, led to the resolution of his painful condition. This prevented the disease from possibly progressing to a full-blown case of CRPS I (RSD) that is very challenging to treat.

微创内固定系统在膝关节周围复杂骨折治疗中的应用

目的探讨AO微创内固定系统(less invasive stab ilization system,LISS)治疗膝关节周围复杂骨折的效果。方法2004年4月~2005年6月对15例干骺端闭合性膝关节周围复杂骨折(左侧9例,右侧6例),分别应用股骨远端LISS或胫骨近端LISS行内固定治疗。结果15例随访5~26个月,平均13.2月。完全负重时间为12~26周,X线骨愈合时间11~24周,无延迟愈合及骨不连。浅表感染1例,皮肤水疱2例,经换药后愈合。无深部感染及皮肤坏死,无骨筋膜室综合征。Johner-W ruhs方法评价功能优11例、良3例、中1例,以优良为满意标准,本组满意率为93.3%(14/15)。1例C3型胫骨平台骨折在术后2周出现胫骨内侧骨块明显移位伴髁间分离,二次手术在胫骨平台内侧加以支撑钢板固定,术后20周骨折愈合,功能评价为良;1例C3型胫骨平台骨折在术后8周出现膝内翻(胫骨平台内翻角为82°),术后20周骨折愈合,功能评价为中。结论LISS适用于单处股骨远端、胫骨近端骨折及骨质疏松性股骨干远端骨折的治疗;对于胫骨平台C3型骨折内侧平台粉碎严重时,不能过分依赖LISS系统,或将接骨板置于内侧,而应该考虑在内侧辅助支撑钢板。
