Case Report39 years , G7P2-1M4 32/40

 SVB 9 years ago

4 First Trimester Miscarriages.

FDIU at 22/40

4

Post Partum: Thrombus in the superficial tributary veins of the right calf.

Enoxaparin – 6 weeks

Autopsy: Foetal thrombotic vasculopathy .

Current Pregnancy : Uncomplicated

Therapeutic Clexane and Aspirin

GDM on Insulin

5

Initial presentation: 3 day history of Headache and intractable vomiting

Treated with anti emetic, fluids and panadol.

• Diagnosis of the intracranial bleed :second presentation .

Second Presentation : Neurological symptoms

Facial droop, Tongue Deviation

Decreased Power and weakness left side.

Investigations

7

Management• Blood pathology

Normal Platelets (273). Normal Coagulation profile (INR1.0, Anti Xa 0.7U)

• Her LMWH and aspirin stopped

• Intravenous steroids ,platelets (for reversal of clexane) then oral dexamethasone for management of her ICH.

• Obstetric management: Steroids for foetal maturity .

• Ultrasound : Well-grown baby i normal dopplers and amniotic fluid index.

• Extensive Rehabilitation

• Repeat CT scan

Management

MRI

• GA, Elective Caesarean section at 38/40 weeks

Baby: Cephalic , 2720g

Currently : Independent with personal care and staying with her parents

DiscussionIncidence of strokes during pregnancy : varies

from region – region,5 – 67 per 100000 deliveries .

Mothers who survive a stroke :Residual neurological deficit varying from 42- 63% .

Maternal mortality :26%

Foetal mortality being 12%

Peri partum – Highest risk.

Strokes secondary to AVM : 7- 17%

EpidemiologyRisk Factors (Pregnancy related)

Advanced maternal age

Pre eclampsia / Eclampsia

Coagulopathy

• Etiology

Pre Eclampsia/ Eclampsia

Aneurysmal Rupture

Bleeding from AVM

Cortical Venous thrombosis.

Enoxaparin in Pregnancy

Anti coagulant of choice.

• Safe.

• Pregnancy complications like venous thromboembolism, recurrent pregnancy loss, pre eclampsia and placental abruption.

• Monitoring :Anti Xa 0.2 to 0.6 units/mL
