Anemia as a risk factor for cerebral venous thrombosis? An old hypothesis revisited. Results of a prospective study.

Background: Several case reports have linked iron deficiency anemia with the occurrence of cerebral venous thrombosis (CVT) or stroke, yet, it is unclear whether this is a chance association.

Methods: In a case-control design data of whole blood count and screening for thrombophilic coagulation abnormalities of 121 prospectively identified patients with CVT and 120 healthy controls were compared. Anemia was defined as a hemoglobin (Hb) concentration of <120 g/l in females, and <130 g/l in males, severe anemia as a Hb <90 g/l.

Cerebral venous thrombosis: an all or nothing disease? Prognostic factors and long-term outcome.

Background: There is insufficient data on short- and especially long-term prognosis of cerebral venous thrombosis (CVT).

Methods: In 79 consecutive patients, we analyzed factors for acute death and functional outcome at hospital discharge and after 6 months as well as long-term prognosis >/=12 months. Neurological deficits were graded on the National Institute of Health Stroke Scale (NIHSS), functional outcome on the modified Rankin Scale (mRS).

Influence of recanalization on outcome in dural sinus thrombosis: a prospective study.

Background And Purpose: Recanalization in dural sinus thrombosis (DST) has been observed previously; however, systematic prospective data are lacking. The influence of recanalization on DST outcome has not yet been thoroughly evaluated.

Methods: Thirty-seven consecutive patients with DST were prospectively examined.
