2014-11-14 小田整理 医学论坛网

近期,广东省心血管病研究所刘健等研究了胸腔镜下二尖瓣生物瓣置换术32例分析,研究发现,胸腔镜下二尖瓣生物瓣置换术创伤小,并发症少,安全可行,使用特殊类型生物瓣可明显减小手术切口大小。该文章发表于2014年05期《中国胸心血管外科临床杂志》上。 该研究旨在探讨胸腔镜下二尖瓣生物瓣置换的经验,评价其临床效果。 研究者选取回顾性分析2013年3~12月在广东省人民医院心血管外科行胸腔镜下二尖瓣生物瓣

近期,广东省心血管病研究所刘健等研究了胸腔镜下二尖瓣生物瓣置换术32例分析,研究发现,胸腔镜下二尖瓣生物瓣置换术创伤小,并发症少,安全可行,使用特殊类型生物瓣可明显减小手术切口大小。该文章发表于2014年05期《中国胸心血管外科临床杂志》上。

该研究旨在探讨胸腔镜下二尖瓣生物瓣置换的经验,评价其临床效果。

研究者选取回顾性分析2013年3~12月在广东省人民医院心血管外科行胸腔镜下二尖瓣生物瓣置换术32例患者的临床资料,其中男14例、女18例,年龄19~80(55.6±17.3)岁,体重37~78(55.7±9.7)kg,体表面积1.30~1.95(1.67±0.16)m2;合并心房颤动5例,术前心功能分级(NYHA)Ⅱ级20例,Ⅲ级11例,Ⅳ级1例;二尖瓣风湿性病变16例,二尖瓣退行性病变11例,感染性心内膜炎4例,合并先天性心脏病1例。

结果显示,所有患者均行胸腔镜下二尖瓣生物瓣置换术,其中采用Medtronic HancockⅡ人工生物瓣27例,Medtronic Mosaic生物瓣5例。同期行三尖瓣成形术13例,房间隔缺损修补术1例。全组患者住院期间无死亡,均顺利出院,住院期间未并发低心排血量综合征及左心室破裂。术后复查心脏彩色超声心动图提示,所有患者人工二尖瓣功能良好,无瓣周漏发生。术后患者心功能较术前明显改善,心功能恢复至Ⅰ级9例,Ⅱ级17例,Ⅲ级6例。术后早期及术后3个月左心房内径及左心室舒张期末内径与术前相比均明显减小。而术后早期及术后3个月左心室射血分数(LVEF)与术前相比有所降低。

胸腹腔镜联合手术治疗食管癌预后好

  南方医科大学南方医院心胸血管外科的一项研究显示,胸腔镜腹腔镜联合手术可以达到开放手术治疗食管癌的疗效及安全性。该论文发表在2012年第6期《中华胃肠外科杂志》。   研究者检索pubmed、Embase、Cochrane图书馆资料库、Google学术搜索、中国生物医学文献数据库及中国期刊全文数据库;检索时间范围均为建库至2011年7月。收集比较胸腔镜腹腔镜联合手术与开放手术治疗食管癌的随机对

Ann Thorac Surg:早期胸腔镜下脓胸引流和剥脱术疗效确切

虽然辅助胸腔镜手术(VATS)胸腔引流和剥脱术已被证明是治疗早期脓胸的有效方法,然而VATS的最佳治疗时机目前仍不清楚。为了评估早期胸腔引流和剥脱术的有效性,来自韩国首尔韩国大学医学中心胸心血管外科的SungHoLee教授等人进行了一项研究,研究结果在线发表于2013年10月8日的《胸外科年鉴》(AnnThoracSurg)杂志上。作者发现脓胸患者症状持续时间小于4周比那些症状持续时间大于4周的患

沪肺癌手术开启3D微创新时代 首例手术成功

戴上“黑超”眼镜,行云流水般“穿越”在人体胸腔内,精准定位、一击命中,上海市第一例3D胸腔镜肺癌微创手术20日在市肺科医院宣告成功。 腔镜下肺癌切除是一项高难度手术,因为肿瘤接近重要脏器,重要血管神经密布,要使手术顺利地进行,需要丰富的胸腔镜手术处理经验,且要求助手小心配合,稍有差池便可能损伤大血管和神经。因此,胸腔镜肺癌手术一直是医学界的一大难点。市肺科医院胸外科主任姜格宁教授介绍,目

BMJ:肺癌患者接受胸腔镜或开胸手术 其术后生存率相当

一项英美联合研究表明,接受胸腔镜肺叶切除的肺癌患者在总体、癌症特异性和无病生存率方面均与接受开胸手术者相当。论文10月2日在线发表于《英国医学杂志》(BMJ)。 研究纳入2007-2009年间接受胸腔镜或开胸肺叶切除术的肺癌患者6008例,其中78%(n=4715)接受开胸手术,中位年龄74岁,中位随访时间40个月。 结果为,在各治疗组均为1195例患者的配对分析中,两组患者的3年

齐鲁救治重度PBMV术后再狭窄患者

近日,山东大学齐鲁医院心血管外科对一例重度二尖瓣球囊扩张成形(PBMV)术后再狭窄患者实施胸腔镜辅助二尖瓣球囊扩张成形术,取得成功。该技术经山东省医药卫生科技信息研究所科技查新,国内外均未查见与该课题相同的胸腔镜辅助PBMV治疗重度二尖瓣再狭窄的文献报道。 患者,女,36岁,因“行经皮二尖瓣球囊扩张成形术后4年,活动后胸闷半年”入院。超声心动图提示:左房62mm,二尖瓣瓣口面积约0.5c

Respirology:可弯曲胸腔镜的活检准确率堪比传统胸腔镜

可弯曲胸腔镜是近年来新兴的一种胸腔镜技术,该技术被成功应用于胸腔疾病的诊断。值得讨论的是,相对于传统的胸腔镜来说可弯曲胸腔镜所取得的活检组织标本是否足够用于病理学诊断。来自斯洛文尼亚呼吸与过敏性疾病大学附属医院的Ales Rozman针对这一问题进行了一项前沿性研究,该研究的目的是通过随机试验对比传统胸腔镜和可弯曲胸腔所取得的活检组织的大小、品质及病理学诊断的难易程度。从而判断可弯曲胸腔镜活检的准
