Treatment of external carotid arteriovenous fistula with detachable balloon

Summary A simple fistula between the external carotid artery and the internal jugular vein was treated for the first time using Debrun's technique with a detachable balloon catheter. The nature of the fistulous connection makes the release of the balloon inflated with silicone completely harmless. The occlusion of the fistula, while maintaining the patency of the remaining branches of the external carotid artery, proves this technique to be the most appropriate for the treatment of arteriovenous fistulae in the neck.     

Sex differences in morphology of the brain stem and cerebellum with normal ageing

The cerebral hemispheres become atrophic with age. The sex of the individual may affect this process. There are few studies of the effects of age and sex on the brain stem and cerebellum. We used MRI morphometry to study changes in these structures in 152 normal subjects over 40 years of age. In the linear measurements, men showed significant age-associated atrophy in the tegmentum and pretectum of the midbrain and the base of the pons. In women, only the pretectum of the midbrain showed significant ageing effects after the age of 50 years, and thereafter remained rather constant. Only men had significant age-associated reduction in area of the crebellar vermis area after the age of 70 years. Both men and women showed supratentorial brain atrophy that progressed by decades. There were significant correlations between supratentorial brain atrophy and the diameter of the ventral midbrain, pretectum, and base of the pons in men, and between brain atrophy and the diameter of the fourth ventricle in women.

Dural arteriovenous fistula of the cavernous sinus with venous congestion of the brain stem: report of two cases.

We present two cases of dural arteriovenous fistula of the cavernous sinus with venous congestion of the brain stem. Both cases were detected by MR imaging and showed significant improvement on MR images after transvenous embolization.     

MRI of adrenoleukodystrophy involving predominantly the cerebellum and brain stem

A case of adult-onset adrenoleukodystrophy involving predominantly the cerebellum and brain stem is described. The patient was a 30-year-old man with no family history of adrenoleukodystrophy. His neurological symptoms were progessive cerebellar ataxia and spastic paraparesis. CT showed atrophy of the cerebellum and brain stem. MRI disclosed lesions, enhancing partially with gadolinium, in the dentate nuclei and the pyramidal tracts from the internal capsule to the brain stem. The biochemical findings were compatible with typical adrenoleukodystrophy, but the distribution of the lesions on MRI was distinctly different. After steroid administration, the patient's symptoms improved slightly and contrast enhancement of the lesions was markedly reduced. Received: 30 May 1995 Accepted: 5 December 1995

儿童先天性股深动静脉瘘的介入栓塞治疗

目的 探讨采用弹簧钢圈及无水乙醇栓塞治疗儿童先天性股深动静脉瘘的临床疗效及安全性.方法 8例先天性股深动静脉瘘的儿童均经B超及动脉造影检查证实为股深动静脉瘘,均接受介入治疗.术中将2.7F微导管插至瘘口处,注入弹簧钢圈或无水乙醇以堵塞瘘支,10 min后再次于股动脉处造影,如果仍然有残余瘘口,使用同样的方法继续堵塞瘘支直至瘘口完全闭塞.实施血管内介入栓塞治疗后4周行血管造影复查,若仍有残余瘘口则再次进行栓塞.随访6个月至2年,观察临床症状及体征改变.结果 动脉造影可清楚地显示股深动脉及其分支以及瘘口情况,3例只见单一瘘口,5例合并多个微瘘口存在.8例患儿共实施介入栓塞术10次,释放弹簧钢圈共47枚,进行无水乙醇栓塞7次,技术操作均成功.无弹簧钢圈异位栓塞,未出现皮肤明显坏死、神经功能损害及心脑肺严重并发症,术中瘘口均立即闭塞.术后4周再次行血管造影复查,7例瘘口完全闭塞,临床症状较前改善,未见复发;1例可见股深动脉分支多发微小瘘口,先后共行3次介入栓塞术,仍见少许残余微瘘存在,但临床症状控制良好,无再发展.结论 介入栓塞治疗儿童先天性股深动静脉瘘是一种安全、有效的方法,有望成为儿童先天性股深动静脉瘘的首选治疗方法.     

Detection of arteriovenous fistula between common and external iliac artery and vein by radionuclide angiography. A case report

A patient with high output cardiac failure was demonstrated to have an arteriovenous fistula between the right common and external iliac artery and vein by radionuclide angiography. The value of radionuclide angiography is described with a review of the literature.     

MR imaging of Chiari II malformation associated with dysgenesis of cerebellum and brain stem

Extensive cerebellar hypogenesis is rare in Chiari II malformation and, to our knowledge, has not been described in modern radiological literature. In our case near total absence of cerebellar tissue and "underdevelopment" of the brain stem were noted in a patient with several characteristic features of Chiari II malformation.     

Postnephrectomy arteriovenous fistula of the renal pedicle treated with detachable balloons: A case report

A case of postnephrectomy arteriovenous fistula of the right renal pedicle is reported here. The diagnosis was confirmed by angiography, and successful treatment was achieved using detachable balloon.     

The arterioles and capillaries of the brain stem and cerebellum: A microangiographic study

Summary A schema of the vascular supply of the brain stem in sagittal sections and of the vascular supply of cerebellum is presented.Contribution of the 1st European Colloquium for Neuroradiology, September 6, 1969 Colmar     

Neonatal pontomedullary disconnection with aplasia or destruction of the lower brain stem: a case of pontoneocerebellar hypoplasia?

We report a neonate who presented with marked hypotonia and absent suck reflex. MR demonstrated complete absence of the pons as well as absence of a basilar artery flow void. Our case exhibits features similar to those described in previous reports of pontoneocerebellar hypoplasia, but with a more severe degree of pontine involvement. The associated vascular findings suggest a vascular insult to the brain stem as the cause.

患者男,51岁,3月前因“腹胀3月余,伴呕血1次”入本院诊治.既往于3年前因外伤行脾脏切除术,入院后CT示:门静脉高压,脾静脉增粗,远端瘤样扩张(图1,2).脾动静脉及门静脉造影(图3,4):脾动脉远端迂曲与脾静脉相通,脾静脉增粗、扩大,可见曲张的胃冠状静脉,门静脉明显增粗.栓塞术后复查CT:脾动静脉瘘口消失,胃冠状静脉已封堵(图5,6).     

A case of achondroplasia with downward displacement of the brain stem

We report a case of achondroplasia with downward displacement of the brain stem. Although upward displacement and anterior angulation deformity of the brain stem are common findings in achondroplasia, they were not observed in this case, because of a coexistent Chiari malformation.     

Blue rubber-bleb nevus syndrome: report of a familial case with a dural arteriovenous fistula

We report a case of a 45-year-old woman known to have a familial form of blue rubber-bleb nevus syndrome (BRBNS). The patient developed severe occipital headaches and bilateral retroauricular bruits. Cerebral angiography showed a large dural arteriovenous fistula in the torcular region. Central nervous system involvement in BRBNS is not often reported, and most cases of BRBNS are sporadic.     

Endovascular treatment of congenital brain arteriovenous fistulas with combination of detachable coils and onyx liquid embolic agent

Introduction  

Congenital brain arteriovenous fistulas (BAVFs) are rare vascular lesions, and conservative management was associated with a high mortality rate. We report our experience in the treatment of congenital BAVFs using detachable coils and Onyx liquid embolic agent.     

Morphometry and 1H-MR spectroscopy of the brain stem and cerebellum in three patients with fragile X-associated tremor/ataxia syndrome

SUMMARY: Morphometry and spectroscopy were performed in 3 patients with fragile X-associated tremor/ataxia syndrome (FXTAS). The brain stem and cerebellum were atrophic and satisfied criteria for olivopontocerebellar atrophy in 2 patients. However, the vermis was relatively spared and the basis pontis maintained its oval shape. The only spectroscopic abnormality was a decrease of the pontine N-acetylaspartate/creatine ratio in 1 patient. Atrophy and metabolic changes in FXTAS differ to some extent from those of olivopontocerebellar atrophy.

硬脊膜动静脉瘘的诊断和治疗进展

硬脊膜动静脉瘘(Spinal dural arteriovenous fistulaSDAVF)是一种常见的脊髓血管畸形,多发于50~60岁的男性,是不明原因的获得性病变[1]。其预后取决于就诊时的神经功能缺失情况[2]。由于本病的临床表现常不具有特异性,所以部分病例的诊断相当困难,早期认识本病非常重要。现就本病的病理、诊断及治疗进展进行综述。一、病理及病理生理SDAVF的瘘口常位于椎间孔处脊神经后根的硬脊膜袖口处,可单发或多发,引流静脉增粗并可返流入脊髓表面静脉或静脉丛。供血动脉为根软膜动脉。椎间孔硬脊膜袖口处的动静脉交通使正常的向心引流模式发生逆转…
