新支架为腹主动脉瘤患者带来福音

2019-03-29 张思玮 科学网

“腹主动脉瘤虽是一种良性疾病,却非常凶险。如果它突然增大并扩张到一定程度,很有可能破裂并引起致命的大出血,就好像是把气球吹破了。”北京清华长庚医院血管外科主任医师吴巍巍表示,腹主动脉瘤就如同人体的“不定时炸弹”。


“腹主动脉瘤虽是一种良性疾病,却非常凶险。如果它突然增大并扩张到一定程度,很有可能破裂并引起致命的大出血,就好像是把气球吹破了。”北京清华长庚医院血管外科主任医师吴巍巍表示,腹主动脉瘤就如同人体的“不定时炸弹”。

不过,多数腹主动脉瘤病人无症状,或感轻度腹部不适,有的病人自己发现腹部有搏动包块,少数病人有较明显的腹部疼痛,可向腰背部放射,剧烈腹痛多提示动脉瘤有破裂趋势,或已破裂。

临床研究表明,60岁以上的老年人、男性、吸烟人群、高血压或心脏病患者等都是患腹主动脉瘤的高危人群。

目前,针对于腹主动脉瘤的治疗,越来越多的临床医生采取主动脉瘤腔内修复技术(endovascular aneurysm repair, EVAR)进行腹主动脉腔内治疗。所谓的EVAR是指通过股动脉,应用特制的输送装置导入覆膜支架,将支架固定于正常段的主动脉壁,隔离高压的动脉血流与动脉瘤壁,从而达到治疗目的。

“与传统开放手术相比,EVAR具有创伤小、术中出血量少、术后恢复快、住院时间短等优点,尤其适用于高危腹主动脉瘤患者。”吴巍巍说。

此外,文献数据还显示,腹主动脉瘤患者大多患有高血压、动脉硬化等基础性疾病,大部分患者会同时合并髂总动脉或髂外动脉的钙化、扭曲、狭窄,严重者甚至完全闭塞,因此,入路动脉狭窄扭曲是腹主动脉瘤腔内修复术中最常见的问题。同时,腹主动脉瘤的瘤颈短而扭曲会带来支架移位、内漏等一系列并发症,也是临床需要长期克服的一个难题。

利好的消息是,国内自主研发的新一代腹主动脉覆膜支架系统——Minos?覆膜支架系统为腹主动脉瘤患者带来福音。

据了解,该系统适用于近端瘤颈长度≥15mm的腹主动脉瘤的治疗,是目前国产唯一一款具有自主知识产权的将输送鞘外径降低至14F(<5mm)的腹主动脉覆膜支架产品,并且采用“带倒钩一体激光雕刻而成的裸段”“无缝复丝覆膜”“主体支架多重小波段编织结构”“分支支架单丝螺旋编织而成”等核心技术,可以满足更多具有复杂解剖形态的腹主动脉瘤的腔内治疗需求,降低支架移位、内漏、分支支架闭塞等常见并发症的发生率,进一步降低远期二次干预的风险。同时,该系统还采用了三件套结构设计,可以灵活组装以满足不同尺寸需求。

“新系统将为上解剖形态复杂的腹主动脉瘤患者提供更好的解决方案,尤其惠及更多入路动脉狭窄扭曲的患者。”苗铮华表示。
