電磁流量計とポータブルDSAによる内頸動脈内膜剥離術の術中評価について

Intraoperative Evaluation of Carotid Endarterectomy with Electromagnetic Flowmetry and Portable DSA

I．はじめに

　頸動脈内膜剥離術（以下CEAと略す．）の目的は塞栓の原因となる内膜潰瘍性病変の除去と血流低下の原因となる血管内腔狭窄の改善である．手術によって，この二つの目的が果たされたかどうかを術中に評価できれば，手術を更に安全に行うことができると思われる．われわれは電磁流量計とポータブルDSAによるCEAの術中評価を行い若干の知見を得たので報告する．

　In order to perform carotid endartrectomy more safely, we have evaluated, intraoperatirely, the result of an operation with electromagnetic flowmeter and portable digital subtraction angiography (DSA). During surgery, flow of the exposed internal and common carotid artery was measured with an electromagnetic flowmeter, before and after endarterectomy. After the closure of the arteriotomy, portable DSA was carried out by injecting contrast medium from the common carotid artery.
