title: [Image anatomic characteristics and clinical diagnosis and treatment of cerebral venous sinus stenosis].
abstract: OBJECTIVE
  To explore the imaging anatomic features of symptomatic cerebral venous sinus stenosis, and evaluate the efficacy and feasibility of different treatment methods.
  
  
  METHODS
  From August 2001 to September 2004, 173 patients (transverse sinus stenosis 150, middle of the superior sagittal sinus stenosis 18, proximal part of sigmoid sinus stenosis 3, straight sinus stenosis 2; combined with sinus diverticulum 14, combined with Labbe's vein stenosis 3) were confirmed venous sinus stenosis by digital subtraction angiography (DSA). Among these patients, 121 were treated by stent implantation and the other 52 with mild symptoms by anticoagulation and/or thrombolysis treatment.
  
  
  RESULTS
  The treatment procedures were succeeded in all patients. 2 patients developed temporal and occipital hemorrhage during the procedure of artery thrombolysis, and 1 patient developed epidural hematoma in the transverse sinus area.All the 3 patients had a satisfactory prognosis through symptomatic treatment.There was no recurrence for all the patients during the follow-up period ranging from 1 to 9 years.9 patients who had recurring dizziness were confirmed no stent stenosis or thrombosis by DSA. The sites of stenosis in 168 patients (97%) were in the connect area of sigmoid and transverse sinuses or in the middle segment of superior sagittal sinus, where arachnoid granulations were focused on according to the anatomic characteristics.
  
  
  CONCLUSIONS
  There is significant correlation between the cerebral venous sinuses stenosis and the abnormal growth of arachnoid granulations in the sinuses; the neurologic deficits caused by venous sinus stenosis can be relieved and eliminated by anticoagulation, thrombolysis, or stent implantation. Favorable medium-long term outcome is showed in the study population.
