INTRODUCTION
Thrombosis of cerebral veins and sinuses is a distinct
stroke, mostly afflicting young middle aged population
with female to male ratio being 3: 1.
1
It is responsible for
0.5% of all stroke cases in developed countries, whereas
in developing realms like India it contributes 10-17% of
all cases.
2,3
Pregnancy and puerperium account for 20%
of CVT cases in Indian population accounting for
4.5/1000 obstetric admissions and 1/250 deliveries.
2,4
In
the pre-antibiotic era post-infective CVT was more
prevalent, whereas nowadays aseptic CVT is more
frequent.
5
The precise incidence of this ailment is not
known because of dearth of available scientifically
intended epidemiological studies in the literature.
However its prevalence is much less when contrasted
with arterial stroke.
ETIOLOGY
More than 100 causes of CVT have been expounded in
literature.
2,4-6
However, despite of extensive
investigations, the cause may be elusive in up to 20-25%
of patients.
6
Currently, infective causes account for less
than 10% of patients, while inherited pro-thrombotic
tendencies account for 10-15% of cases.
2,7
Pregnancy and
puerperium have long been recognized as periods of
increased susceptibility.
7-11
Significantly increased risk
has been associated with caesarean delivery, increased
maternal age, hyperemesis, inter-current infection and
maternal hypertension. Increased risk during pregnancy
and puerperium is due to a hypercoagulable state caused
by increased levels of fibrinogen, Factors VII, VIII and
X, Diminution in inhibitors of Protein S coagulant,
Increase in inhibitors of Protein C level, increased ability
to neutralize Heparin.
10-14
Also oral contraceptive pills

ABSTRACT
Cerebral venous thrombosis is an uncommon but serious neurologic disorder in young adults with a peculiarly high
preponderance for females. Diagnosis is frequently overlooked or deferred due to its subacute or lingering onset and
the wide spectrum of clinical symptoms. Headache is the most frequent symptom occurring in up to 95% of all cases.
One must consider stroke in all cases of neurological deterioration in pregnancy and puerperium. Imaging plays a
primary role in diagnosis with magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
having proven to be the best both for diagnosis and follow-up of these women. Current therapeutic measures used
include the utilization of anticoagulants such as dose-adjusted intravenous heparin or body weight adjusted
subcutaneous low-molecular-weight heparin (LMWH), the use of thrombolysis and symptomatic therapy including
control of seizures and elevated intracranial pressure. Recurrence in future pregnancy is usually low.
