a, b Magnetic resonance venography suggests there is a stenosis at the border of the transverse sinus and sigmoid sinus on the right side. The picture shows that the patient’s left transverse sinus and sigmoid sinus are a congenital developmental disadvantage. c The digital subtraction angiography (DSA) clearly shows the stenosis at the border of the transverse sinus and sigmoid sinus on the right side. d After the patient accepted intracranial stenting, the stenting was placed at the border of the transverse sinus and sigmoid sinus on the right side. DSA shows the stent directly solved the VSS
