  • 專業解析

    腸系膜上動脈(Superior Mesenteric Artery)詳解

    腸系膜上動脈(SMA)是腹主動脈的主要分支之一,位于腹腔幹下方約1厘米處,約在第一腰椎水平發出。它負責為小腸大部分(空腸和回腸)、盲腸、闌尾、升結腸和橫結腸近端2/3提供血液供應,是消化系統重要的供血動脈。

    一、解剖結構與分支

    1. 主要分支:

      • 空腸動脈與回腸動脈:供應空腸和回腸,形成多級動脈弓以保證腸道蠕動時的血流穩定。
      • 回結腸動脈:供應回腸末端、盲腸和闌尾,其分支闌尾動脈是急性闌尾炎手術的關鍵标志。
      • 中結腸動脈:供應橫結腸,與腸系膜下動脈的分支形成吻合支(Riolan弓)。
      • 右結腸動脈:供應升結腸(部分人群可能缺如,由回結腸動脈代償)。
    2. 解剖位置關系:

      • 前方:胰頸和脾靜脈;
      • 後方:腹主動脈、左腎靜脈;
      • 左側:腸系膜下靜脈;
      • 右側:腸系膜上靜脈(與動脈伴行)。

    二、生理與臨床意義

    1. 腸缺血的關鍵動脈:

      SMA是急性腸系膜缺血(AMI)最常見的受累血管,多因栓塞或血栓導緻劇烈腹痛,需緊急幹預。

    2. 腸系膜上動脈綜合征:

      當SMA與腹主動脈夾角過小(正常約38°-65°)時,可能壓迫十二指腸水平部,引起餐後嘔吐和營養不良。

    3. 外科手術标志:

      在胰十二指腸切除術中,SMA是界定切除範圍的重要邊界,需精細分離以避免損傷。

    三、影像學與診斷

    CT血管成像(CTA)是評估SMA病變的金标準,可清晰顯示狹窄、栓塞或動脈瘤。超聲多普勒則用于監測血流速度,輔助診斷慢性腸缺血。

    網絡擴展資料

    Superior Mesenteric Artery(腸系膜上動脈)是解剖學中的一個重要術語,由三個部分組成:

    1. Superior(上方的/較高的):來源于拉丁語,表示“位置較高”或“處于上方”。在此處指該動脈位于腸系膜動脈系統的上部。

    2. Mesenteric(腸系膜的):與腸系膜(mesentery)相關。腸系膜是腹膜的一部分,負責固定小腸并為其提供血管、神經和淋巴通路。

    3. Artery(動脈):指運輸富氧血液離開心髒的血管。

    整體定義:
    腸系膜上動脈是腹主動脈的一個主要分支,起源于主動脈上部(約在第1腰椎水平),主要向小腸、盲腸、升結腸和部分橫結腸供血。


    功能與臨床意義:


    補充:
    在臨床操作中,該動脈常作為腹腔手術的重要标志,例如在動脈導管結紮術中需準确定位以避免損傷。
