Abstract

Background Idiopathic Intracranial Hypertension (IIH), is defined by increased cerebral spinal fluid (CSF) pressure in the absence of other causes of intracranial hypertension. There has been recent interest in the role of intracranial venous sinus stenosis in IIH. The raised pressures in IIH are argued to worsen by the secondary appearance of the venous sinus stenosis.

Objective 5 patients have undergone endovascular pressure measurement in Wales and their clinical details including history, examination, initial management, neuroimaging pre- and post venous stenting, and follow-up (6–24 months) to provide the first case study of patients undergoing Venous sinus stenting in Wales.

Methods 5 patients with IIH refractory to first line treatments underwent venography and manometry and 4 patients underwent stenting of the venous sinuses after this procedure had shown a pressure gradient proximal to stenosis in the lateral sinuses.

Results Three patients were rendered asymptomatic, two were improved including one patient unmasking a different headache disorder following treatment.

Conclusions Stenting in venous stenosis provides a further treatment option to patients refractory to first line treatments with IIH. This case series highlights in selected cases treatment is promising with good outcomes.
