  • the present invention relates to the technical field of heart and blood vessel surgery, in particular to a method and device for heart and blood vessel intervention operations such as endocardial myocardial biopsy via radial artery or ulnar artery.
  • Endocardial myocardial biopsy is a technique for obtaining materials for cardiac examination, and it is a representative cardiac intervention operation.
  • the pathological results of endocardial myocardial biopsy are the gold standard for the diagnosis of non-ischemic cardiomyopathy. It has important clinical significance in the diagnosis of myocarditis, the diagnosis of the cause of unexplained heart failure, and the monitoring of rejection after heart transplantation.
  • Endocardial myocardial biopsy is divided into left ventricular endocardial myocardial biopsy (hereinafter referred to as “left heart biopsy”, which must be completed via arterial route) and right ventricular endocardial myocardial biopsy (hereinafter referred to as “right heart biopsy”, which requires intravenous route) carry out).
  • Right heart biopsy is done by puncturing the catheter through the internal jugular vein, subclavian vein, femoral vein and other venous routes, and entering the myocardial biopsy forceps through the venous catheter. Most of the myocardial tissue is clamped in the ventricular septum.
  • right ventricle wall is thin (usually less than 4mm), complications such as heart perforation are prone to occur during myocardial biopsy, while the left ventricular wall is thicker (about 10mm). Therefore, right heart biopsy is safer than left heart biopsy difference.
  • right heart biopsy can only be taken from the ventricular septum, and the scope of sampling is limited, and most heart diseases involve the left heart. The effectiveness of right heart biopsy is not as good as that of left heart biopsy.
  • some patients undergoing myocardial biopsy require coronary angiography, left ventricle angiography, and heart or arterial vascular system interventions, while coronary angiography, left ventricular angiography, and heart or arterial vascular system interventions can be done through the arterial route.
  • one method of left heart biopsy is through the femoral artery. Due to the large diameter of the femoral artery (about 8mm), the risk of bleeding and complications at the puncture site (such as vagal reflex, arteriovenous fistula, retroperitoneal hematoma, etc.) are higher. .

Description

经桡动脉或尺动脉进行心脏及血管介入手术的方法及装置 技术领域
本发明涉及心脏及血管手术技术领域,尤其是一种经桡动脉或尺动脉进行心内膜心肌活检等心脏及血管介入手术的方法及装置。
背景技术
心内膜心肌活检术是进行心脏检查的一种取材技术,是一种有代表性的心脏介入手术。心内膜心肌活检的病理结果是非缺血性心肌病诊断的金标准,在心肌炎的诊断、不明原因心衰的病因诊断、心脏移植术后排异反应的监测等方面有重要的临床意义。
心内膜心肌活检分为左心室心内膜心肌活检(以下简称“左心活检”,须经动脉途径完成)与右心室心内膜心肌活检(以下简称“右心活检”,须经静脉途径完成)。右心活检经颈内静脉、锁骨下静脉、股静脉等静脉途径穿刺置管,经由静脉置管内进入行心肌活检钳,大多在室间隔钳夹心肌组织。因右心室室壁较薄(一般小于4mm),心肌活检过程中容易发生心脏穿孔等并发症,而左心室室壁较厚(约10mm左右),因此,右心活检的安全性比左心活检差。其次,右心活检大多只能在室间隔取材,取材范围有限,且心脏疾病大多累及左心,右心活检的有效性不如左心活检。此外,心肌活检的一部分患者需行冠脉造影、左心室造影及心脏或动脉血管系统介入手术等,而冠脉造影、左心室造影及心脏或动脉血管系统介入手术等可经由动脉途径完成,这部分患者如采取右心活检则需要接受动脉、静脉两次穿刺置管,手术操作繁琐,并发症几率增加,患者也会承受较大的痛苦。因此,与右心活检相比,左心活检更加安全、有效、简捷。
目前,左心活检的一种方式是经股动脉途径,由于股动脉直径较大(8mm左右),出血风险及穿刺部位并发症(如迷走反射、动静脉瘘、腹膜后血肿等)风险较高。还有一种经桡动脉进行左心活检的途径,采用的是Sheathless导引导管技术,该技术的具体操作步骤为:1.进行桡动脉穿刺置入动脉鞘管,经动脉鞘管置入器械完成相应操作(根据具体临床情况而定);2.撤回动脉鞘管中的器械;3.撤回动脉鞘管,导丝保留在动脉中,这时需要术者用力压迫桡动脉穿刺口以免出血;4.助手协助术者将带有扩张器的Sheathless导引导管经由导丝置入桡动脉,继而经肱动脉、锁骨下动脉送至升主动脉;5.将扩张器从Sheathless导引导管撤出,将Pigtail导管送入Sheathless导引导管,Sheathless导引导管和Pigtail导管同时进入左心室;6.撤回Pigtail导管,Sheathless导引导管保留在左心室内,经Sheathless导引导管送入的心肌活检钳在室间隔或游离壁钳夹心肌组织。在此过程中,长约100cm的Sheathless导引导管持续穿入桡动脉的过程以及术中对Sheathless导引导管转动和推拉,均会直接对桡动脉穿刺口 产生持续刺激,对穿刺口的持续刺激容易造成动脉痉挛,严重动脉痉挛会导致手术的失败,目前已有因Sheathless导引导管对穿刺口的刺激而导致手术失败的案例。此外,在动脉鞘管撤出桡动脉后,需持续压迫穿刺口,容易产生因配合不当造成过多的失血;Sheathless导引导管头端很软,常与其自身扩张器配合不好,在心脏大血管中操作,容易产生大血管损伤等并发症。

实施例1
本实施例提供了本发明的经桡动脉或尺动脉进行心脏及血管介入手术的方法的第一种实施方式,该方法是进行心脏心内膜心肌活检的方法,包括:
步骤一、将动脉鞘管置于穿刺后的动脉血管中,动脉血管为桡动脉血管或尺动脉血管;
在该步骤之前,首先对患者的桡动脉或尺动脉穿刺处进行常规消毒、铺巾及局部麻醉后,穿刺桡动脉或尺动脉,具体采用桡动脉还是采用尺动脉进行手术根据患者的具体情况确定。
步骤二、通过短导丝将导引导管从体外穿入动脉鞘管并从其另一端穿出,送至左心室内,撤出短导丝,导引导管留置于左心室内;
步骤三、将心肌活检钳通过导引导管送至左心室内膜,咬切一部分心肌组织;具体地,在透视下调整心肌活检钳的位置,回撤心肌活检钳约1.0cm,张开咬切器,重新将心肌活检钳向左室心内膜送入,一旦感到阻力,快速闭合咬切器,平稳回拽心肌活检钳使其脱离左心室壁,在心肌活检钳撤出时保证咬切器处于闭合状态。在该步骤之前,采用肝素盐水纱布擦 拭心肌活检钳。在此过程中,可调整导引导管的位置以便使活检钳达到不同位置取得心肌组织,导引导管也不会对穿刺处进行持续刺激,进一步减少了血管痉挛的几率,增加手术成功率。
步骤四、将心肌活检钳撤出导引导管至体外,留取心肌组织标本;重复步骤三和步骤四可分别于室间隔、左室游离壁钳取心肌组织4~10块,在相邻两次活检操作间期用肝素盐水冲洗导引导管及肝素盐水清洗心肌活检钳。待血液涌出导引导管后,用肝素盐水清洗心肌活检钳和肝素盐水冲洗导引导管,避免将导引导管中可能存在的血栓、掉落的心肌组织等冲入左心室内,造成外周动脉栓塞。
步骤五、采用短导丝将导引导管从动脉鞘管中撤出,拔出动脉血管内的动脉鞘管,对穿刺口进行加压包扎。
本实施例中,在进行步骤五之前,还可以选择性地进行左心室造影,即完成心肌活检后,向导引导管内注射显影剂进行左心室造影,以除外心肌穿孔等并发症。
本实施例进行心内膜心肌活检手术的方法,在进行经桡动脉或尺动脉的血管穿刺置管后,在手术过程中不需要穿刺其它部位血管,也无需将动脉鞘管从动脉血管中抽出更换其它鞘管或Sheathless导引导管,患者术后无需卧床,更加舒适,可以减少对穿刺部位刺激带来的相关并发症,同时可以降低更换长鞘管导致的动脉痉挛几率、更换鞘管过程中的失血风险和穿刺部位血肿等并发症的几率。
实施例2
本实施例提供了本发明的经桡动脉或尺动脉进行心脏及血管介入手术的方法的第二种实施方式,该方法在一次心脏介入手术中进行冠脉造影和心内膜心肌活检手术,该方法包括:

本实施例中,在进行步骤八之前,还可以选择性地进行左心室造影,即完成心肌活检后,向导引导管内注射显影剂进行左心室造影,以除外心肌穿孔等并发症。
本实施例进行冠脉造影和心内膜心肌活检手术的方法,在进行经桡动脉或尺动脉的血管穿刺置管后,在手术过程中不需要穿刺其它部位血管,也无需将动脉鞘管从动脉血管中抽出更换其它鞘管或Sheathless导引导管,可以减少对穿刺部位刺激带来的相关并发症,患者术后无需卧床,更加舒适,同时可以降低更换长鞘管导致的动脉痉挛几率、更换鞘管过程中的失血风险和穿刺部位血肿等并发症的几率;并且,能够通过一次手术完成冠脉造影和心肌活检,使心脏病介入的“一站式”诊疗成为可能,大大减轻需要进行多个手术患者的痛苦,增加手术的成功率。

本实施例进行冠脉造影、左心室造影和心脏心内膜心肌活检手术的方法,在进行经桡动脉或尺动脉的血管穿刺置管后,在手术过程中不需要穿刺其它部位血管,也无需将动脉鞘管从动脉血管中抽出更换其它鞘管,可以减少对穿刺部位刺激带来的相关并发症,患者术后无需卧床,更加舒适,同时可以降低更换长鞘管导致的动脉痉挛几率、更换鞘管过程中的失血风险和穿刺部位血肿等并发症的几率;并且,能够通过一次手术完成冠脉造影、左心室造影和心肌活检,使心脏病介入的“一站式”诊疗成为可能,大大减轻需要进行多个手术患者的痛苦,增加手术的成功率。
在其他实施方式中,也可以先进行步骤五~七的左心室造影手术,再进行步骤二~四的冠脉造影手术。
实施例5
本实施例提供了本发明的经桡动脉或尺动脉进行心脏及血管介入手术的方法的第五种实施方式,该方法在一次心脏介入手术中进行冠脉介入治疗手术和心脏心内膜心肌活检手术,该方法包括:
步骤一、将动脉鞘管置于穿刺后的动脉血管中,动脉血管为桡动脉血管或尺动脉血管;
在该步骤之前,首先对患者的桡动脉或尺动脉穿刺处进行常规消毒、铺巾及局部麻醉后,穿刺桡动脉或尺动脉,具体采用桡动脉还是采用尺动脉进行手术根据患者的具体情况确定。
步骤二、通过短导丝将导引导管从体外穿入动脉鞘管并从其另一端穿出,送至主动脉窦,撤出短导丝;由于在穿刺处的动脉血管的直径较小,从穿刺处到主动脉窦,动脉血管的直径是逐渐增加的,因此,动脉鞘管不需要过长,在造影导管从动脉鞘管的另一端穿出时,动脉血管的直径就已增加,造影导管从该处的动脉血管即可很容易地穿入到主动脉窦。置于动脉血管中的动脉鞘管保证造影导管能够稳定地穿至主动脉窦,这样,对穿刺处不会产生持续刺激,减少了血管痉挛的几率,增加手术成功率。
步骤三、通过导引导管注入显影剂,进行冠脉造影,和/或通过导引导管进入冠脉介入治疗器械,进行冠脉介入治疗手术;
步骤四、完成冠脉造影或冠脉介入治疗手术后,将导引导管撤出冠脉开口,将短导丝从导引导管体外端穿入并从其处于动脉血管内的另一端穿出,在短导丝辅助下,将导引导管送至左心室内,撤出短导丝,导引导管留置于左心室内。
步骤五、将心肌活检钳通过导引导管送至左心室内膜,咬切一部分心肌组织;具体地,在透视下调整心肌活检钳的位置,回撤心肌活检钳约1.0cm,张开咬切器,重新将心肌活检 钳向左室心内膜送入,一旦感到阻力,快速闭合咬切器,平稳回拽心肌活检钳使其脱离左心室壁,在心肌活检钳撤出时保证咬切器处于闭合状态。在该步骤之前,采用肝素盐水纱布擦拭心肌活检钳。在此过程中,可调整导引导管的位置以便使活检钳达到不同位置取得心肌组织,导引导管也不会对穿刺处进行持续刺激,进一步减少了血管痉挛的几率,增加手术成功率。
步骤六、将心肌活检钳撤出导引导管至体外,留取心肌组织标本;重复步骤五和步骤六可分别于室间隔、左室游离壁钳取心肌组织4~10块,在相邻两次活检操作间期用肝素盐水冲洗导引导管及肝素盐水清洗心肌活检钳。待血液涌出导引导管后,用肝素盐水清洗心肌活检钳和肝素盐水冲洗导引导管,避免将导引导管中可能存在的血栓、掉落的心肌组织等冲入左心室内,造成外周动脉栓塞。
步骤七、完成心肌活检后,采用导引导管行左心室造影,以除外心肌穿孔等并发症。
步骤八、采用短导丝将导引导管从动脉鞘管中撤出,拔出动脉血管内的动脉鞘管,对穿刺口进行加压包扎。
本实施例中,在进行步骤八之前,还可以选择性地进行左心室造影,即完成心肌活检后,向导引导管内注射显影剂进行左心室造影,以除外心肌穿孔等并发症。
本实施例进行冠脉造影或冠脉介入治疗手术和心内膜心肌活检手术的方法,在进行经桡动脉或尺动脉的血管穿刺置管后,在手术过程中不需要穿刺其它部位血管,也无需将动脉鞘管从动脉血管中抽出更换其它鞘管,可以减少对穿刺部位刺激带来的相关并发症,患者术后无需卧床,更加舒适,同时可以降低更换长鞘管导致的动脉痉挛几率、更换鞘管过程中的失血风险和穿刺部位血肿等并发症的几率;并且,能够通过一次手术一条导引导管完成冠脉介入治疗和心肌活检,尤其适合冠脉介入治疗与心内膜心肌活检手术,使心脏病介入的“一站式”诊疗成为可能,节省了医疗费用,大大减轻需要进行多个手术患者的痛苦,增加手术的成功率。

本实施例中的经桡动脉或尺动脉进行心脏介入手术的装置,在将桡动脉或尺动脉的动脉血管穿刺后,在心脏介入手术进行的过程中不需要将动脉鞘管从血管中抽出,不会使患者失血过多,降低因穿刺部位血肿等并发症的发生几率,导引导管2和心肌活检钳3穿入到动脉鞘管中进行手术,不会对穿刺处产生持续刺激,动脉鞘管1与穿刺处不发生位移,减少了相应的刺激和血管痉挛的几率,增加手术成功率。此外,在使用本方案的装置进行手术的过程中,无需使用Sheathless导引导管技术中的扩张器,在以往的Sheathless导引导管手术装置中由于扩张器头端尖锐,如操作不当,会增加血管和心脏瓣膜的损伤几率,而在本方案提供的装置中则不会出现该问题。此外当患者需要进行冠脉造影手术、左心室造影手术和心肌活检手术时可采用本实施例中的装置依次进行,患者只需要进行一次动脉穿刺,无需进行其它血管穿刺,大大减轻了患者的痛苦,提高了手术的成功率。
本实施例中的动脉鞘管1、导引导管2和心肌活检钳3尺寸可根据具体临床病人状况选择的尺寸组合情况如下表所示。
Figure PCTCN2019129865-appb-000001
Figure PCTCN2019129865-appb-000002
需要注意的是,动脉鞘管1壁厚小于等于0.40mm,导引导管2壁厚小于等于0.30mm;导引导管2外径和动脉鞘管1内径差大于等于0.003mm,即要留有一定的间隔供导引导管2穿入动脉鞘管1内;心肌活检钳3外径和导引导管2内径差大于或等于0.003mm,保证一定的导引导管2内的空间进行手术。
导引导管2、造影导管4和Pigtail导管在未进行手术之前,其形态可以是图2或图4所示的形态或本领域所用导管的其它形态。
在进行心脏及血管介入手术时,选择采用桡动脉或采用尺动脉进行手术时,具体视患者的血管情况而定。
需要说明的是,除了上述给出的具体实施例之外,本实施例中的经桡动脉或尺动脉心脏及血管介入手术的装置还可以应用于其他的心脏及血管介入手术,而这些都是本领域技术人员在理解本发明思想的基础上基于其基本技能即可做出的,故在此不再一一例举。
最后,可以理解的是,以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式,然而本发明并不局限于此。对于本领域普通技术人员而言,在不脱离本发明的原理和实质的情况下,可以做出各种变型和改进,这些变型和改进也视为本发明的保护范围。
