肠系膜上动脉(Superior Mesenteric Artery)详解
肠系膜上动脉(SMA)是腹主动脉的主要分支之一,位于腹腔干下方约1厘米处,约在第一腰椎水平发出。它负责为小肠大部分(空肠和回肠)、盲肠、阑尾、升结肠和横结肠近端2/3提供血液供应,是消化系统重要的供血动脉。
主要分支:
解剖位置关系:
SMA是急性肠系膜缺血(AMI)最常见的受累血管,多因栓塞或血栓导致剧烈腹痛,需紧急干预。
当SMA与腹主动脉夹角过小(正常约38°-65°)时,可能压迫十二指肠水平部,引起餐后呕吐和营养不良。
在胰十二指肠切除术中,SMA是界定切除范围的重要边界,需精细分离以避免损伤。
CT血管成像(CTA)是评估SMA病变的金标准,可清晰显示狭窄、栓塞或动脉瘤。超声多普勒则用于监测血流速度,辅助诊断慢性肠缺血。
来源:
Superior Mesenteric Artery(肠系膜上动脉)是解剖学中的一个重要术语,由三个部分组成:
Superior(上方的/较高的):来源于拉丁语,表示“位置较高”或“处于上方”。在此处指该动脉位于肠系膜动脉系统的上部。
Mesenteric(肠系膜的):与肠系膜(mesentery)相关。肠系膜是腹膜的一部分,负责固定小肠并为其提供血管、神经和淋巴通路。
Artery(动脉):指运输富氧血液离开心脏的血管。
整体定义:
肠系膜上动脉是腹主动脉的一个主要分支,起源于主动脉上部(约在第1腰椎水平),主要向小肠、盲肠、升结肠和部分横结肠供血。
功能与临床意义:
补充:
在临床操作中,该动脉常作为腹腔手术的重要标志,例如在动脉导管结扎术中需准确定位以避免损伤。
