11. 頸動脈結紮術に対する術前検査としてのballoon occlusion testの有用性

抄録

It is important to determine the safety of internal carotid artery (ICA) ligation in order to identify those patients who are likely to develop severe cerebral ischemia if this procedure is carried out. For the purpose of reducing the risk of ICA ligation, temporary balloon occlusion by the Swan-Ganz method was performed. Observations of neurological state (tolerance test) and carotid artery back pressure, A-J blood sampling for gas analysis (PjO₂,% CBF reduction), cerebral angiography for assessing collateral circulation, EEG monitoring, and rCBF measurement by the xenon inhalation method were undertaken during temporary ICA occlusion.
Our diagnostic procedure allows the risk associated with ICA ligation to be estimated more exactly.
