Role of cerebral digital subtraction angiography in the evaluation of pulse synchronous tinnitus.

Journal: Journal Of Otology

Objective: The aim of this study was to evaluate the value of digital subtraction angiography (DSA) in the diagnostic evaluation of a highly selected patient population presenting with pulse-synchronous tinnitus (PST).

Methods: We retrospectively reviewed the charts of all patients referred for evaluation of possible vascular etiology of pulsatile tinnitus. Patients were evaluated with regards to presenting signs, comorbidities, non-invasive imaging results, angiographic findings and outcomes.

Results: Fifteen patients underwent cerebral DSA. Dural arteriovenous fistula (dAVF) was identified in six patients, and five patients had other significant vascular pathology identified on DSA. Seven patients with 'negative' non-invasive imaging were found to have significant pathology on DSA.

Conclusions: Catheter angiography may have a significant yield in appropriately selected patients presenting with pulse synchronous tinnitus.
