Utility of transoral and transcranial ultrasonography in the diagnosis of internal carotid dissection: a case report

Abstract

Internal carotid artery (ICA) dissection is one of the most common causes of stroke in young patients. Ultrasonographic assessment of the carotid artery is the method of choice for early detection. The use of the conventional technique for diagnosis is limited since dissection frequently occurs in the distal portion of the ICA. Case Report: We describe the case of a 48-year-old Argentinian woman with malignant cerebral infarction secondary to ICA dissection. We diagnosed her with neck vessels using conventional ultrasonography and a transoral ultrasonographic approach combined with transcranial ultrasonography. Conclusion:We recommend the transoral assessment of ICA combined with ultrasonography as a noninvasive method for the diagnosis of ICA dissection.

Cerebral circulatory arrest diagnosed with transoral Doppler ultrasonography

“…5 In this situation, a transoral approach with an endocavitary probe can be used to assess the internal carotid and vertebral arteries as they ascend vertically behind the posterolateral pharyngeal wall. 5,6 To our knowledge, this is the first case that report the usefulness of internal carotid and vertebral arteries Doppler ultrasonography using a transoral approach in the diagnosis of CCA.…”

“…Evaluation can be challenging in situations with short necks, high bifurcations, or the presence of a central venous catheter, even though high‐frequency linear transducer are frequently used to examine the internal carotid and vertebral arteries. 5 In this situation, a transoral approach with an endocavitary probe can be used to assess the internal carotid and vertebral arteries as they ascend vertically behind the posterolateral pharyngeal wall 5,6 …”
