A, Timeline of the FPs in the SSS during 9 life months in patient 5. B, Course of Doppler FPs in the SSS under endovascular interventional therapy of stenosis of the jugular bulb in patient 5 (in the angiography room at the age of 16 weeks). A (upper left), An US Doppler FP in the SSS directly before balloon dilation on the left showing an arterialized retrograde flow. B (upper right), After balloon dilation and stent implantation on the left side decrease in flow velocities with reduced retrograde flow. C (bottom left), After additional balloon dilation on the right side, further reduction of the retrograde flow component and normalization of the flow direction. D (bottom right), At 24 hours after the procedure, further normalization of the US Doppler FP and increased undulation with minor retrograde components. Vmax indicates maximum velocity; Vmin, minimum velocity.
