Abstract:
Transcranial Doppler (TCD) can be useful in the diagnosis and validation of surgical treatment of vertebrobasilar insufficiency (VBI). A case is reported in which TCD confirmed the diagnosis of vertebrobasilar insufficiency and validated the indication of surgery by detecting a bidirectional flow in a stenotic and compressed vertebral artery. In the postoperative period and at late follow-up TCD demonstrated a restored antegrade flow, as a consequence of a well functioning revascularization. Surgical indication of VBI is rare and TCD can be proposed as part of routine patients' study before a surgical decision is taken.
