這篇短文介紹了如何由胸前掃描SVC(上腔靜脈)
Intensive Care Medicine的FB連結
“semi-recumbent position, phased array probe with transducer at left parasternal border between II-IV ICS, marker vertical/cephalad direction angled medially 30°–45° until ascending aorta visualized, probe adjusted to obtain longitudinal axis”
由下方示意圖可見
1。患者擺位: Semi-recumbent (30-40度傾斜)
2。Phase array (可由肋間掃描到較深處)
3。探頭放在緊靠胸骨的第2-4肋間,指向頭側,垂直於皮膚,往胸骨處內傾約30-45度角
4。通常會先看到升主動脈,再調整一下向內傾斜角度,就有機會看到SVC


掃描的困難度在於會遇到呼吸過程肋膜的遮蓋干擾,
再來由於需要傾斜很大的角度,掃描的困難度實在是很高。
我覺得這是很具有挑戰性的掃描,臨床實用性有待驗証,
以下示範為我本人的SVC variation
