专业解析

科里根氏征(Corrigan's sign),也称为水冲脉(Water hammer pulse)或陷落脉(Collapsing pulse),是临床医学中一个重要的脉搏体征,特指一种脉搏异常表现。它主要与主动脉瓣关闭不全(Aortic regurgitation)这一心脏瓣膜疾病高度相关。

以下从汉英词典角度对其详细解释:

  1. 定义与表现 (Definition & Manifestation):

    • 中文描述: 指在触诊患者桡动脉时,感知到的一种特征性脉搏。其特点是脉搏快速上升(骤起),达到高峰后迅速下降(骤降),脉压差(收缩压与舒张压之差)显著增大。感觉上,脉搏冲击有力但持续时间短暂,如同潮水急速涌来又急速退去,故名“水冲脉”;或感觉脉搏在指下突然陷落,故名“陷落脉”。
    • 英文对应: Corrigan's sign is characterized by arapidly rising and falling pulse with awide pulse pressure. It feels like a forceful, bounding impulse that collapses abruptly under the fingers, hence the names "Water hammer pulse" or "Collapsing pulse".
  2. 病理机制 (Pathophysiology):

    • 中文描述: 该体征产生的核心机制是主动脉瓣关闭不全。心脏舒张期,本应关闭的主动脉瓣无法有效闭合,导致血液从主动脉大量反流回左心室。这使得舒张压显著降低。同时,为了代偿反流的血量,左心室在收缩期会增强收缩,将更多血液泵入主动脉,导致收缩压升高。这一升一降的结果就是脉压差显著增大,形成了特征性的骤起骤落的脉搏波形。
    • 英文对应: The sign results primarily fromaortic valve incompetence. During diastole, blood flows back from the aorta into the left ventricle due to the leaky valve, causing adecrease in diastolic blood pressure. To compensate, the left ventricle ejects a larger stroke volume during systole, leading to anincrease in systolic blood pressure. This combination results in awidened pulse pressure and the characteristic pulse contour.
  3. 临床意义 (Clinical Significance):

    • 中文描述: 科里根氏征是诊断中重度主动脉瓣关闭不全的重要线索和经典体征之一。虽然并非所有主动脉瓣关闭不全患者都出现典型的科里根氏征(尤其在轻度时),但它的存在强烈提示该疾病。医生通常在体格检查中通过触诊桡动脉或股动脉来检测此体征,并需结合听诊(主动脉瓣听诊区的舒张期杂音)、其他周围血管征(如枪击音、杜氏双重杂音等)以及超声心动图(确诊的金标准)进行综合判断。
    • 英文对应: Corrigan's sign is aclassic and important clue for diagnosing moderate to severe aortic regurgitation. While not present in all cases (especially mild), its detection strongly suggests the condition. It is typically assessed during physical examination by palpating the radial or femoral artery and must be interpreted in conjunction with auscultation (diastolic murmur over the aortic area), other peripheral signs of AR (e.g., Traube's sign, Duroziez's sign), and confirmed by echocardiography (the diagnostic gold standard).
  4. 命名由来 (Eponym):

    • 中文描述: 该体征以19世纪爱尔兰医生Dominic John Corrigan爵士(1802-1880)的名字命名。他于1832年首次详细描述了主动脉瓣关闭不全及其相关的脉搏特征。
    • 英文对应: The sign is named afterSir Dominic John Corrigan (1802-1880), an Irish physician who first provided a detailed description of aortic insufficiency and its associated pulse characteristics in 1832.
