大脑后动脉假性动脉瘤临床上非常少见,其病理学特点表现为多种原因造成动脉破裂出血形成血肿,血肿吸收后残留假腔所致。由于缺乏真正的动脉瘤壁结构,极易破裂出血,其死亡率及病残率较高。对此病做出早期诊断并选择正确的治疗方案对于挽救患者生命是非常重要的。我们于2004年6月收治1例,结合病史、头颅MRA和全脑数字减影血管成像(DSA)证实为左侧大脑后动脉P1段假性动脉瘤,经小片段蓝宝石可脱卸弹簧圈(SDC)栓塞术后治愈出院。 相似文献

BACKGROUND AND PURPOSE:Spontaneous or progressive occlusion of the posterior fossa dural sinuses is often observed in patients with vein of Galen malformation, which can affect the clinical course. The aim of this study was to examine the patency of the posterior fossa dural sinuses in patients with vein of Galen malformation and to analyze the clinical and angiographic course of this condition.MATERIALS AND METHODS:We retrospectively reviewed 61 consecutive children with vein of Galen malformations. Clinical presentation, management, outcome, and angiographic change were analyzed for the patients with attention paid to all dural sinus occlusions.RESULTS:Twenty patients (32.8%) demonstrated spontaneous sinus occlusion, mostly in the sigmoid sinus. This condition was not observed in neonates and was first discovered during infancy or childhood. Progression of sinus occlusion was seen in 10 patients, and the conditions of 6 of them deteriorated in accordance with the progression of sinus occlusion. After total or subtotal obliteration of the malformation by transarterial glue embolization, 13 patients recovered to healthy, 3 patients had only mild developmental delay, and 4 patients remained neurologically disabled.CONCLUSIONS:Spontaneous sinus occlusion is not a rare condition and can result in neurologic deterioration in the natural history of untreated vein of Galen malformation. If signs of progressive sinus occlusion are noticed, early arteriovenous shunt reduction or elimination by transarterial glue embolization is expected to prevent permanent brain damage.Vein of Galen malformations (VGMs) are direct arteriovenous shunts in the subarachnoid space of the velum interpositum cistern and quadrigeminal cistern, supplied by the choroidal and quadrigeminal arteries and drained by the dilated median prosencephalic vein of Markowski, the embryonic precursor of the vein of Galen.1,2 This malformation is considered to form between 6 and 11 weeks of gestational age when this transient embryonic vein exists.The clinical presentation of VGM varies depending on the age of the patient. Neonates typically present with high-output congestive heart failure due to high-flow shunt producing cardiac overload, whereas infants and children usually present with hydrovenous disorders, such as macrocrania, prominent facial and scalp veins, and hydrocephalus.2,3 Hydrovenous disorders result from diminished absorption of CSF due to cerebral venous hypertension.4 Development of outflow restriction in the posterior fossa dural sinuses will improve the cardiac overload but will lead to further intracranial venous hypertension, which will not only interfere with absorption of CSF but will also create congestion within cerebral veins. Venous hypertension consequently results in brain tissue loss and hence developmental delay.2,3Thus, posterior fossa dural sinus occlusion is thought to aggravate the clinical course of VGM. However, its incidence, pathogenic mechanism, and the effect of endovascular embolization are unknown. The aim of this study was to analyze the clinical and angiographic course of patients with VGM with sinus occlusion and to determine whether embolization can prevent clinical deterioration in these patients. 相似文献

A 12-week-old baby with a vein of Galen aneurysmal malformation (VGAM) was successfully treated with performing transarterial microcatheter-directed embolization with Berenstein Liquid Coils and n-butyl cyanoacrylate in the feeding arteries. Post-procedure angiography showed a marked decrease of the blood flow into the dilated vein of Galen. Three months later, follow-up angiography showed that the vein of Galen aneurysmal malformation had totally disappeared, and the baby recovered very well without any sequelae. We report here on this interesting case along with a review of the relevant literature, and we aim to enhance physicians'' awareness of the treatment for VGAMs. 相似文献
