Abstract:
OBJECTIVETo explore the feasibility of using an intracavitary convex array probe for detecting the distal extracranial internal carotid artery (ICA) by transoral carotid ultrasonography (TOCU).
METHODSForty patients underwent examinations with bilateral ICA inspected with an intracavitary convex array probe by TOCU to observe the internal diameter, visible length, peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI).
RESULTSEight of the 40 patients were excluded from the observation for the presence of carotid plaques. The examination was terminated in two patients due to sensitive throat and severe pharyngeal reflex. The rest of the patients completed the examination of the internal diameter, visible length, PSV, EDV and RI, which showed no statistically significant differences among them (P>0.05).
CONCLUSIONUsing intracavitary convex array probe, the distal extracranial ICA disease can be diagnosed with higher accuracy.
