目的探讨分析脑动静脉畸形破裂出血的相关危险因素。方法回顾性分析127例脑动静脉畸形患者的临床资料,破裂出血患者(71例)作为出血组,未发生破裂出血患者(56例)为对照组。对两组患者的临床资料进行因素分析。结果单因素分析显示,出血组与对照组的畸形血管团位置、畸形血管团大小、供血动脉位置、引流静脉的方向、合并动脉瘤及所合并动脉瘤大小比较差异有统计学意义(P<0.05);非条件多因素Logistic回归分析结果显示,位于深部的小于3cm血管团、深部引流静脉、合并动脉瘤与脑血管畸形是破裂出血的危险因素(P<0.05,OR>1)。结论对于深部血管团小于3cm、深部引流静脉、合并动脉瘤的脑血管畸形患者,应尽早实施手术治疗。 相似文献

Background Endovascular therapy plays an important role in the treatment of brain arteriovenous malformations (BAVMs). Ethylene vinyl alcohol copolymer (Onyx) is a novel liquid embolic material. This study aimed to summarize our experience of using Onyx for embolization of BAVMs with the focus on embolization technique. Methods From September 2003 to November 2007, 115 patients (43 women and 72 men, with a mean age of 29 years) with BAVMs were endovascularly treated with Onyx in our department. The following features of all AVMs were evaluated prior to treatment: type of nidus and shunt, draining veins, and feeding arteries. A total of 196 endovascular procedures were performed. Results The course of endovascular treatment was completed in 88 patients. Additional sessions were planned in 27 patients. Of the 88 patients, total occlusion was obtained in 23 patients (26.1%), near-total (〉80% of the original volume) occlusion was obtained in 35 patients (39.8%) and partial occlusion (〈80% of the original volume) was obtained in 30 patients (34.1%) using embolization as the sole therapeutic technique. Mean volume reduction was 72% (range 30%-100%) in 115 patients. Thirty four patients (38.6%, 34/88) underwent radiosurgical treatment. Additional embolization sessions were planned in 27 patients. Complications occurred in 19 patients (16.5%, 19/115), leading to death in one patient (mortality 0.9%) and permanent disabling in 3 patients (morbidity 2.6%). Conclusions Onyx was shown to be feasible and safe for embolization of BAVMs. Proper use of the Onyx injection technique largely improved the endovascular treatment of BAVMs. Large AVMs can be adequately reduced in size through the use of additional treatment. 相似文献

Onyx in treatment of large and giant cerebral aneurysms and arteriovenous malformations 总被引:1,自引:0,他引:1
Onyx, a novel embolization material, is a mixture of ethylene-vinyl alcohol copolymer ( EVOH ), dimethyl sulfoxide (DMSO), and micronized tantalum. The polymer is dissolved in DMSO and is prepared in different concentration. Onyx HD-500 for aneurysm embolization contains 20% copolymer and 80% DMSO. Onyx-18 for arteriovenous malformations ( AVMs ) embolization contains 6.0% copolymer and 94. 0% DMSO. When Onyx comes in contact with water or blood, the copolymer precipitates because of rapid diffusion of the DMSO solvent. It possesses stronger cohesiveness, but less likely to entrap the microcatheter. From September 2003, 相似文献

Clinical and pathological changes in cerebral arteriovenous malformations after stereotactic radiosurgery failure 总被引:1,自引:1,他引:0
Background Stereotactic radiosurgery is an altemative to resection of intracranial cerebral arteriovenous malformations (AVMs), while it will fail in some cases. This study aimed to evaluate the changes after stereotactic radiosurgery for AVMs.
Methods Nineteen cases with cerebral AVMs had failure after stereotactic radiosurgery therapy. The symptoms and angiography were assessed. All patients underwent microsurgery. Pathologic examination was performed for all cases and electron microscopic examination was carried out in 6 patients.
Results Seven cases had hemorrhage from 12 to 98 months after stereotactic radiosurgery, 5 had headache, 4 had refractory encephalon edema, 2 had epilepsy as a new symptom and 1 had a pressure cyst 5 years after radiosurgery. Angiography in 18 cases, 8-98 months after radiation therapy, demonstrated no significant changes in 5 cases, slight reduction in 9, near complete obliteration in 1 and complete obliteration in 3. An abnormal vessel was found on pathologic examination in 17 cases, even one case had obliterated in angiography. Electron microscopy examination showed vessel wall weakness, but the vessels remained open and blood circulated. One case died because of a moribund state before surgery. The other 18 cases had no new neurological deficiencies, seizure control and no hemorrhage occurred after microsurgery at an average follow-up of 3 years.
Conclusion Stereotactic radiotherapy for AVMs should have a long period follow-up. If serious complications occur, microsurgery can be performed as salvage treatment. 相似文献

目的 探讨侧裂区动静脉畸形(AVM)的手术治疗效果.方法 回顾性分析2000年1月至2009年3月于北京天坛医院神经外科脑血管病区手术治疗的94例侧裂区AVM患者临床资料.根据畸形血管巢与侧裂的解剖学相对位置关系对其进行分类,同时记录术后神经系统并发症及恢复情况.结果 94例侧裂区AVM可分为侧裂前、侧裂后、侧裂深部、侧裂上以及单纯侧裂AVM 5类.所有患者均全切病灶并经术后脑血管造影(DSA)证实.术后神经系统并发症多为一过性,包括偏瘫8例(合并失语5例),单纯失语1例.另有2例(2.1%)术后分别出现手术侧硬膜外血肿及颅内出血.所有患者出院时KPS评分均高于90分.结论 侧裂区动静脉畸形可累及多个脑功能区,周围血供丰富,是目前AVM治疗的难点之一.但其治疗不应过于保守,仍建议显微手术切除作为此类颅内动静脉畸形的主要治疗手段.Abstract: Objective To evaluate the microsurgical treatment for sylvian fissure arteriovenous malformations (AVMs).Methods The clinical data of 94 sylvian fissure AVMs treated microsurgically was retrospectively collected.They were classified as medial, lateral, deep, anterior and simple AVMs according to the anatomic location of nidus in sylvian fissure.Results Total lesion removal was achieved in all patients and it was confirmed by postoperative digital subtraction angiography. Transient neurological deficits, including slight hemiparesis (n=5, 5.3%) and aphasia (n=4, 4.3%), were documented.Another 2 patients (2.1%) presented with a postoperative epidural and an intracranial hematoma respectively. However, an excellent outcome was observed in all patients as indicated by the Karnofsky performance scale >90.Conclusion The microsurgical treatment for sylvian fissure AVMs has been greatly restrained by the involvement of multiple brain functional regions and its anatomic complexity. A more aggressive approach is recommended. 相似文献
