成人异常体动脉供血肺基底段与肺隔离症CT影像对比研究
发布时间:2021-12-15 23:58
研究背景:异常体动脉供血肺基底段是一种罕见的先天性异常,其动脉供应来自肺下叶的一个或多个基底节。动脉供应起源于胸降主动脉的异常动脉。大多数研究人员声称,最常见发病部位是左肺下叶基底节。以前有研究将异常体动脉供血肺基底段称归类为Pryce I型肺隔离,但受累肺的气管支气管树结构并无异常,与支气管肺隔离症不同。“隔离”一词表示肺组织是否与正常支气管连接仍有争议。异常体动脉供血肺基底段的病因尚不清楚,可能是由于这种异常与肺胚胎学相关。研究表明,大多数病人没有症状。然而,患有这种异常情况的患者更容易出现咯血、劳力性呼吸困难、持续性干咳、心脏杂音等症状,尤其是儿童,在儿童时期,由于左路心脏超负荷可能导致连续胸部杂音和充血性心脏衰竭,而在成年后,咳血可能存在,也可能表现为无症状,体检中偶然发现。计算机断层扫描(CT)是一种证实性检查,可显示局灶性磨砂玻璃混浊(GGO)和全身动脉异常血管,用于诊断正常肺的全身动脉供血异常。其他的调查方式包括胸透,在不复杂的病例中,可以看到均匀的混浊或斑片状的实变。由于急性感染或慢性炎症,可出现明显的囊性间隙,并可看到空气-液体水平,提示病变支气管相通。磁共振成像(M...
