电解可脱性弹簧圈血管内栓塞治疗颅内动脉瘤

目的 探讨颅内动脉瘤血管内栓塞治疗的效果及栓塞技术要点。方法 应用微导管技术,在数字减影血管造影（DSA）监视下,对颅内动脉瘤行血管内栓塞治疗。结果 用电解可脱性弹簧圈（GDC）成功栓塞183例188个动脉瘤,痊愈182例,死亡1例。结论 血管内栓塞治疗颅内动脉瘤是一种安全、可靠、有效的治疗手段。     

血管内支架治疗颅内动脉瘤的临床疗效初步报告

目的 探讨使用血管内支架结合电解可脱弹簧圈(GDC)治疗颅内宽颈及梭形动脉瘤的可行性。方法 15例颈内动脉宽颈囊状动脉瘤及2例椎动脉梭形动脉瘤，经全脑血管造影确诊后将支架置入载瘤动脉，跨动脉瘤颈放置。其中13例通过支架网孔将微导管送入动脉瘤腔，填塞电解可脱弹簧圈，4例仅放置支架治疗。结果 1例术后1周死亡，2例失访。3～6个月造影随访14例，11例动脉瘤消失，2例动脉瘤大部消失，1例动脉瘤复发。载瘤动脉均保持通畅。结论 血管内支架置入是治疗颅内动脉瘤的新技术，结合GDC技术可为颅内宽颈囊状动脉瘤和梭形动脉瘤的治疗提供新的选择。     

Endovascular management of a patient after SAH

Treatment of acute aneurysmal subarachnoid hemorrhages consists of occluding the aneurysm to prevent rebleed, attempting to prevent vasospasm, and maintaining blood flow to the brain through vessels in vasospasm. Endovascular treatment has been shown to be as safe as, or safer, than surgical clipping for patients with SAH. Engineering solutions to our clinical problems continue to improve endovascular outcomes. This article reviews the current state of endovascular therapy.     

Persistent primitive trigeminal artery associated with aneurysm: report of two cases and review of the literature

We present two cases of persistent primitive trigeminal artery (PPTA) associated with a giant aneurysm originating at the opening of the PPTA on the internal carotid artery (ICA). In one case, opening of the PPTA occurred 4 months after balloon occlusion of the ICA, when a giant aneurysm located at the cavernous segment of the ICA was being treated. The PPTA was occluded successfully using a Guglielmi detachable coil (GDC). A vertebral artery approach was taken. This is the first report of the opening of a PPTA associated with contrast filling of the aneurysm after balloon occlusion of the parent artery. The possibility of contrast filling of the aneurysm via potential PPTA should therefore be considered in the event of an ICA aneurysm with parent artery occlusion.     

经数字减影血管造影行颅内动脉瘤栓塞术的麻醉体会

目的探讨经数字减影血管造影(DSA)行颅内动脉瘤电解可脱性弹簧圈(GDC)栓塞术的麻醉效果。方法22例经DSA行颅内动脉瘤GDC栓塞术的患者全部采用静脉快速诱导气管内插管,术中以微量泵持续泵注丙泊酚、瑞芬太尼,间断静脉注射维库溴铵维持肌松,持续泵注尼莫地平,以防血管痉挛,控制性降压等方法处理。结果22例经DSA行颅内动脉瘤GDC栓塞术的患者麻醉诱导、术中维持,术后苏醒平稳,控制性降压效果满意,无动脉瘤破裂。结论经DSA行颅内动脉瘤栓塞术麻醉处理的关键是:选择合适的麻醉药物,采取有效措施防止脑血管痉挛和动脉瘤再破裂,控制血压降低颅内压,以提高手术成功率。

Tumor Resistance Explained by Hormesis

Enhanced drug (GDC 0449) resistance in a mouse model for human medulloblastoma is shown in the present paper to act via an hormetic response. This has significant implications, imposing constraints on the quantitative features of the dose response of the chemotherapeutic agent, affecting optimal study design, mechanism assessment strategy, potential for tumor rebound, patient relapse and disease outcome.
