Key result
Prolonged supraorbital opacity pulse propagation time identifies internal carotid artery occlusion.
Why the study?
Atraumatic evaluation methods for carotid arterial disease are needed to improve screening in patients with cerebrovascular symptoms.
Does opacity pulse propagation measurement detect carotid arterial occlusion in patients with cerebrovascular symptoms?
Observational (n=27)
Does opacity pulse propagation measurement detect carotid arterial occlusion in patients with cerebrovascular symptoms?
Opacity pulse propagation time measurement may serve as a useful atraumatic screening tool for detecting carotid arterial occlusion.
No takes yet. Share an insight, caveat, or question.
May support noninvasive carotid occlusion screening in symptomatic patients; leaves open diagnostic accuracy and clinical utility pending validation.
Heck et al. (1970) conducted an observational in Cerebrovascular symptoms (n=27). Opacity pulse propagation time measurement vs. Normal extracranial vessels was evaluated on Mean propagation time to internal and external carotid beds. Opacity pulse propagation time to the medial supraorbital area was prolonged on the side of unilateral internal carotid occlusion, suggesting utility as an atraumatic screening technique.
