Blood flow changes in the transverse-sigmoid sinus junction following effective surgical reconstruction for unilateral pulsatile tinnitus with sigmoid sinus wall anomalies: a four-dimensional flow magnetic resonance imaging analysis.

ABSTRACT:

Background

Pulsatile tinnitus (PT) with sigmoid sinus wall anomalies (SSWAs) is often treated by surgical reconstruction. However, the effect of this surgical procedure on the PT-related blood flow is unclear. This study compared changes in the PT-related blood flow velocity and patterns in the transverse-sigmoid sinus junction (TSSJ) before and after surgical reconstruction using four-dimensional (4D) flow magnetic resonance imaging (MRI).

Methods

A retrospective study analyzed patients with unilateral pulse-synchronous PT confirmed to have ipsilateral SSWAs on preoperative CT, who underwent surgical reconstruction and had pre- and postoperative 4D flow MRI, with PT eliminated or significantly alleviated after at least 6 months of follow-up.
