LOPEZ-ESPEJO, M.; HERNANDEZ-CHAVEZ, M.  y  HUETE, I.. Clinical and radiological features of cerebral venous thrombosis in a children cohort. Rev. chil. pediatr. [online]. 2018, vol.89, n.5, pp.621-629. ISSN 0370-4106.


Cerebral venous thrombosis (CVT) is an uncommon and poorly studied condition in the pediatric population.


To describe and compare the clinical and radiological features of non-neonatal children with CVT according to age and to analyze their association with functional impairment or mortality at hospital discharge.


An observational cohort study of chil dren older than 30 days with a first CVT diagnosed with imaging/venography by magnetic resonance (IMR/VMR). We measure functionality with the modified Rankin scale defining marked impairment with 3 to 5 points. We used U-Mann-Whitney test to compare ages averages between groups with and without the different studied variables (significance < 0.05). We used logistic regression analyses to estimate the risk of adverse outcome for each variable expressed in Odds Ratios (ORs) and 95% confidence intervals (CI).


Among 21 patients recruited, 42.8% were girls, median age 6.27 years (Interquartile range: 0.74-10). The average age was lower in children with diagnostic delay > 48 hours (p = 0.041), score < 12 in the Glasgow coma scale (p = 0.013), seizures (p = 0.041), sinus rectus thrombosis (p = 0.011), and intracranial hemorrhage (p = 0.049); while it was significantly higher in children with intracranial hypertension syndrome (p = 0.008). The presence of some chro nic systemic condition (OR = 11.2; CI = 1.04-120.4), deep CVT (OR = 14; CI = 1.3-150.8), and brain ischemia (OR = 15.8; CI = 1.4-174.2) was associated with marked functional impairment or mor tality at discharge.


Clinical and radiological features of CVT are age-related. Chronic illnesses, deep venous system involvement, and brain ischemia predict adverse short-term outcomes.
