Restenosis of the sigmoid sinus after stenting for treatment of intracranial venous hypertension: case report

Neuroradiology. 2003 Dec;45(12):911-5. doi: 10.1007/s00234-003-1112-z. Epub 2003 Nov 5.


We report what we believe to be the first case of restenosis of the sigmoid sinus after stenting, in a 42-year-old man with an arteriovenous malformation with progressive right hemiparesis secondary to venous hypertension. Angiography revealed severe stenosis of the left sigmoid sinus, which was dilated with a self-expandable stent. Six months after the procedure, however, the sinus was again severely stenosed. Intravascular sonography revealed intimal proliferation in the stented sinus. It was dilated percutaneously, and the venous pressure decreased from 51 to 33 mmHg. On sonography, the intimal tissue decreased in thickness and the diameter of the stent enlarged a little.
