Emergence of Venous Stenosis as the Dominant Cause of Pulsatile Tinnitus
نویسندگان
چکیده
Background The role of arteriovenous shunts such as dural fistulas, arterial steno?occlusive states, anatomic variants, and hypervascular tumors in the genesis pulsatile tinnitus (PT) has long been recognized. On venous side, diverticula, high?riding jugular bulb, sinus wall dehiscence have also implicated. However, overall most common cause—venous stenosis (VSS)—continues to be underrecognized. Its clinical importance, separate from association with intracranial hypertension, requires emphasis. Methods A retrospective review last consecutive 208 cases PT seen at our institution was performed cause determined, when possible, based on radiographic data. Results VSS (34% cohort). Over 90% are women. Typical presentation a unilateral whoosh?like sound sync heartbeat that could completely or nearly abolished by ipsilateral compression. This scenario virtually guaranteed presence VSS, very high sensitivity, specificity, positive, negative predictive values. About two thirds patients harbored other variations bulb diverticulum, should not misinterpreted primary PT. Most did signs symptoms even though cerebrospinal fluid pressures frequently elevated. Conclusions appears identifiable Judicious attention this finding can immensely helpful prompt accurate diagnosis.

We describe a 54-year-old man with a disabling objective pulsatile tinnitus due to a diverticulum of the sigmoid sinus toward the ipsilateral mastoid. We performed a surgical intervention via the endovascular route using coils to obliterate the diverticulum and a stent to avoid coil migration . The patient had a complete and ...

متن کاملPulsatile tinnitus.
Pulsatile tinnitus is an uncommon otologic symptom, which often presents a diagnostic and management dilemma to the otolaryngologist. This symptom always deserves a thorough evaluation to avoid disastrous consequences from potentially life-threatening associated pathology. In most pulsatile tinnitus patients a treatable underlying etiology can be identified.
متن کاملPulsatile tinnitus.
Pulse-synchronous tinnitus suggests a vascular etiology and is deemed rare by the otologic literature. During the period 1978-1985 we evaluated 20 patients with the sole or initial complaint of pulsatile tinnitus. Fourteen patients had objective pulsatile tinnitus, perceived by the patient and the examiner alike, and 6 had subjective pulsatile tinnitus, perceived by the patient only. Angiograph...
