现在肿瘤的类型越来越多，像主动脉假性动脉瘤我们之前可能都没听说过。它们都长什么样子呢，主动脉假性动脉瘤的症状有哪些呢？我们都需要了解过后，才能对其做好防护措施。


\"主动脉假性动脉瘤的症状有哪些\"


很多假性动脉瘤有进行性疼痛，并有扩张性及搏动性肿块，在肿块部位可闻及收缩期吹风样血管杂音，当合并动静脉瘘时，为持续性隆隆样杂音，压迫和阻断近段血流时杂音减弱或立即消失。根据假性动脉瘤发生的部位不同，又有其特殊的临床表现：位于股深动脉的假性动脉瘤，可有大腿上段明显肿胀及搏动性疼痛；腹主动脉瘤破裂所致的后腹膜假性动脉瘤，主要表现为突发性腰背部疼痛；位于颅内或腕部的假性动脉瘤，由于受到空间的限制使周围压迫症状更为突出，表现为局灶症状和定位体征；椎动脉起始部的假性动脉瘤可由于其压迫周围组织引起吞咽困难、气管移位、喘鸣等；另外，胸主动脉破人食管，腹主动脉破人肠管引起相应症状亦有报道。感染性假性动脉瘤通常还伴有全身、局部的炎症反应，包括：发热、乏力及红、肿、热、压痛，肿块的搏动可能因周围软组织肿胀而不易扪及。

你听说过主动脉根部感染性心内膜炎疾病吗？您知道它的易感因素是什么吗？找良医网接下来为您详细解答，其实主动脉根部感染性心内膜炎的易感因素有以下几点：

\"主动脉根部感染性心内膜炎的易感因素\"

 

1、心脏结构异常，最常见的局部心脏结构异常为先天性主动脉瓣二瓣化畸形，其他心脏异常还见于退行性钙化性主动脉瓣狭窄、结缔组织病性主动脉瓣关闭不全、风湿性心脏瓣膜病。以上心脏结构异常导致心腔内出现喷射性血流，造成心内膜损伤。

 

2、曾行主动脉瓣人工瓣膜置换术，主动脉瓣人工瓣膜置换术后感染性心内膜炎的发生率为0.2-1.4/100患者-年，大约1.4%发生于术后1年之内。人工机械瓣常出现缝合缘的感染，生物瓣感染可出现于瓣叶或缝合缘，同种瓣和自体肺动脉瓣感染出现部位与自身主动脉瓣相同。

 

3、菌血症，拔牙、洗牙、口腔冲洗等口腔科手术、各种介入手术、静脉毒品注射等均为常见的造成菌血症的原因，细菌定植于损伤的心内膜，最终导致感染性心内膜炎。

 

感染性心内膜炎可造成主动脉瓣叶损毁，并可扩展至主动脉瓣环和周围组织形成主动脉根部脓肿。脓肿还可破入心包腔或心腔。主动脉根部结构破坏，在主动脉内血流、血压的作用下发生破裂，可形成主动脉根部假性动脉瘤。

 

主动脉根部感染性心内膜炎还可造成冠状动脉和体循环动脉感染性栓塞，患者常出现脑梗塞、脑出血以及肝、脾、肾、肢体等脏器感染性动脉瘤、梗塞、脓肿形成。

肾上型腹主动脉假性动脉瘤应建立胸腹联合切口，第7肋间进胸，腹直肌旁切口经腹膜外游离至腹膜后腹主动脉周围间隙，切开隔肌贯通胸腹切口暴露腹主动脉假性动脉瘤，分别阻断假性动脉瘤近远端腹主动脉后剖开并切除假性动脉瘤，补片修补主动脉破口或应用人工血管置换腹主动脉并重建腹腔干、肠系膜上动脉和双肾动脉与人工血管的连接。

腹主动脉假性动脉瘤的临床体现

 

肾下型腹主动脉假性动脉瘤应通过腹正中切口进腹，切开后腹膜暴露假性动脉瘤，分别阻断假性动脉瘤近远端腹主动脉后剖开并切除假性动脉瘤，补片修补主动脉破口或应用人工血管置换腹主动脉。

 

肾下型腹主动脉假性动脉瘤破口距离肾动脉大于2cm的患者还可以进行带膜支架主动脉腔内修复术。腹主动脉带膜支架主动脉腔内修复术多用于年龄较大或同时合并有其他脏器功能障碍不适合开腹手术的非感染性假性动脉瘤的患者，但带膜支架主动脉腔内修复术不能解除假性动脉瘤造成的压迫症状。

你知道假性动脉瘤是什么意思吗？假性动脉瘤是指动脉壁全层结构破坏或内膜中层破坏、仅残留主动脉外膜，血液溢出血管腔外，被周围组织包裹，其动脉瘤壁已经没有完整动脉壁的三层结构，为动脉周围组织或仅残存主动脉外膜。

\"什么是假性动脉瘤\"

 

 

病因和发病机制，所有能造成主动脉壁结构破坏的因素都可能是主动脉假性动脉瘤的病因，包括外伤、感染、既往曾行心脏主动脉手术或介入治疗、遗传因素、退行性变、免疫因素等。

 

病理生理，假性动脉瘤可压迫周围脏器，如气管、支气管、肺脏、食管、上腔静脉、无名静脉、喉返神经、颈交感神经节，出现相应的临床症状。假性动脉瘤腔内血流缓慢，极易形成附壁血栓，如附壁血栓脱落，可在血流冲击下堵塞远端主动脉分支血管，造成脏器或肢体缺血，甚至发生坏死。假性动脉瘤破裂的危险性很大，根据Laplace定律，瘤壁承受的压力与血压和瘤体半径成正比，血压越高、瘤体越大，瘤壁承受的压力越大，假性动脉瘤破裂的可能性越大。假性动脉瘤一旦破裂，多数患者迅速发生出血性休克而死亡。

 

临床表现，多数患者早期无特异性症状，临床症状与发病原因有密切关系，可能因其他疾病就诊进行体格检查或影像学检查时偶然发现本病。随着假性动脉瘤增大，渐出现疼痛、压迫周围脏器的症状和体征。

 

疼痛：性质多为钝痛，有时为持续性痛，也可随呼吸或体力活动而加剧。疼痛部位可随动脉瘤位置不同而不同。升主动脉或主动脉弓部动脉瘤可出现胸骨后或颈部疼痛。降主动脉动脉瘤可出现肩胛间区疼痛或左胸部疼痛。胸腹主动脉和腹主动脉的假性动脉瘤可出现背痛、腹痛。

 

压迫症状：主动脉弓部假性动脉瘤可压迫气管、支气管而出现刺激性咳嗽、呼吸困难等症状，严重时可引起肺不张、支气管扩张、支气管和肺部感染等。压迫上腔静脉可出现上腔静脉阻塞综合征的症状：进行性头、面、上肢水肿，重者可波及颈部及胸背，皮肤呈紫红色，胸壁静脉曲张。弓部和峡部的动脉瘤可压迫喉返神经出现声音嘶哑、饮水反呛，压迫颈交感神经节可出现单侧瞳孔缩小、眼睑下垂、眼球内陷和颜面无汗等综合征的表现。降主动脉动脉瘤可压迫食管出现咽下困难，晚期可破入食管、气管或支气管出现大量呕血、喀血，造成失血性休克或窒息而死亡。腹主动脉瘤可破入十二指肠出现上消化道大量出血而导致患者死亡。

 

栓塞：可以发生脑、肾、腹腔脏器、肢体等不同部位的栓塞，出现相应的缺血、坏死症状。

主动脉瘤是一种血管瘤，是由于局部血管薄弱，受到血液不断冲击所造成的，而并非一种肿瘤。主动脉瘤也属于大血管疾病，可分为真性、假性以及夹层动脉瘤三种，根据分型的不同，治疗方法也有所区别。主动脉瘤的真性和假性怎么区别呢？


\"主动脉瘤的真性和假性应怎么区别\"

 

主动脉瘤的真性和假性存在不同，应及时、正确地区别，在完善相关检查的基础上，借助检查结果进行判断。真性、假性或夹层动脉瘤是一种结构上的区分，要注意无论是真性或假性主动脉瘤，由于其发生位置的特殊，处于出入心脏血管之上，血管瘤往往不断扩张，危险性高，患者如果不经正规治疗，自然预后不佳。

 

真性主动脉瘤的发病原因有多种可能，主要包括动脉粥样硬化、马凡氏综合征、感染、炎症等。真性主动脉瘤仍存在全层血管结构，即外膜、中层和内膜。而假性主动脉瘤血管壁多发生于感染或血管受到损伤者，其主动脉三层结构已由于曾经血管腔破裂血液流出而不再完整，血管破口为周围组织所包围，虽然已形成血肿，仍可能再次破裂，引发危险。

 

根据症状、体征和辅助检查不难鉴别真性、假性以及夹层主动脉瘤，经检查确诊后，应及时进行外科手术治疗，用人工血管置换病变位置，切除动脉瘤。如果存在介入适应证，考虑进行血管内支架介入，复发几率降低，有助于改善预后。

 

综上所述，主动脉瘤的真性和假性之间存在区别，真性主动脉瘤仍保留了三层动脉血管结构，而假性主动脉瘤没有完整的血管结构，其本身被周围组织所围绕其中。除了两者的结构性区别以外，一般假性主动脉瘤的发生与感染和创伤有关，而真性主动脉瘤的发生原因存在多种可能。患者在出现疑似症状时，应及时就医检查，明确诊断，选择积极治疗，以降低猝死风险，帮助患者长期生存。

主动脉假性动脉瘤是指主动脉管壁被撕裂或穿破，血液自此破口流出而被主动脉邻近的组织包裹而形成血肿。病因多为外伤，如车祸、刀扎伤，亦可为动脉硬化。主动脉假性动脉瘤一旦确诊，必须积极治疗。

主动脉假性动脉瘤是至因某些创伤或者其他原因导致的动脉壁全层破裂出血，被周围组织包裹引起血肿，临床上特征为局部疼痛、波动性包块及局部压迫症状的一种疾病。最近几年随着动脉内治疗的发展，动脉穿刺处假性动脉瘤发生率也随之增加。

 

\"专家为您描述主动脉假性动脉瘤是什么\"

　　

假性动脉瘤大多继发血管损伤，如外伤、刀刺伤、手术创伤、胰腺炎后并发症、动脉粥样硬化等。因为血管周围有比较厚点的软组织，在血管破口附近形成血肿，因动脉搏动的持续冲击力使血管破口与血肿相通形成搏动性血肿，血肿机化形成外壁，血肿腔内面为动脉内膜细胞延伸产生内膜，叫作假性动脉瘤。与之相对应的真性动脉瘤，差别在于真性动脉瘤瘤体有动脉壁的中层及外层。

现在疾病越来越多，但是究竟是怎么形成的呢，大家却不能够知道，因此也就不能对症下药。今天我们就一起来了解一下主动脉假性动脉瘤引起的原因到底是什么呢？


\"主动脉假性动脉瘤引起的原因\"


疾病因素(10%)

部分动脉壁肌肉中层由于动脉粥样硬化或高血压等慢性疾病而缓慢恶化。由动脉粥样硬化所造成的动脉瘤很可能是一种香肠形的肿大，这种动脉瘤叫做梭形动脉瘤，它会沿着动脉的一小段发展出来。

 

感染(15%)

不管是什么原因造成的发炎，都会使动脉壁变得薄弱。大多数的动脉发炎是由诸如结节性多动脉炎，或细菌性心内膜炎(见感染性心内膜炎)等疾病所造成。

 

先天性因素(35%)

动脉壁有三层组织，动脉的支撑力量是由中间肌肉层所提供的，而这层组织可能有先天性的缺陷。受影响的动脉中的正常血压会造成一种气球似的肿大，这种肿大叫做囊形动脉瘤。由于先天性缺陷所造成的动脉瘤几乎总是发生在脑基部的动脉中，由于其形状以及由于几个动脉瘤常会聚生在一起，所以它们又被称之为“浆果”动脉瘤。

 

找良医网温馨提示：以上就是关于主动脉假性动脉瘤引起的原因的介绍，希望能对大家有所帮助，希望各位定期做身体检查，如有身体不适请及时到医院就诊，早日查清病况及早治疗。最后，祝愿大家身体健康！
