Key Takeaway

Consider thrombectomy for postpartum CVST with deterioration despite anticoagulation, but evidence is limited to one case.

This is a single case report describing endovascular mechanical thrombectomy in a 22-year-old woman 12 days postpartum with extensive cerebral venous sinus thrombosis and progressive neurological deterioration despite anticoagulation. The intervention used aspiration and stent-retriever techniques. The comparator was not reported.

The primary outcome of successful venous recanalization was achieved in 1 of 1 patient. The secondary outcome of complete neurological recovery without residual deficits was also reported in 1 of 1 patient at 6 months of follow-up. No effect size, p-value, or confidence interval was reported.

The only adverse event noted was transient vasospasm. Serious adverse events, discontinuations, and tolerability were not reported. Funding or conflicts of interest were not reported.

The authors acknowledge that the evidence is limited and that this is a single case report. The report highlights endovascular mechanical thrombectomy as a potential therapeutic option for postpartum patients with extensive cerebral venous sinus thrombosis and progressive neurological deterioration despite anticoagulation. However, given the study design, no conclusions about efficacy or safety can be drawn, and the findings should be interpreted with caution.

How this fits prior evidence

This case report extends prior coverage of endovascular approaches in cerebral venous sinus thrombosis, including a report of near-complete recanalization of the superior sagittal sinus with a NeVa stent retriever, though that evidence was also limited to one case. It also aligns with prior recognition that vasospasm after thrombectomy may signal microvascular failure needing vasodilators, as transient vasospasm was the only adverse event noted here. The report addresses a gap in postpartum CVST management, where prior coverage noted 8.28% acute maternal mortality and 3.17% recurrence, with heterogeneous anticoagulation data.

A single case report describes a 22-year-old woman who developed a serious blood clot in the brain's venous sinuses 12 days after giving birth. Despite receiving standard treatments like heparin and other medications, her neurological condition continued to worsen. Doctors then performed an endovascular mechanical thrombectomy, which uses specialized tools to remove the blockage.

The procedure was successful in opening the blocked veins. At a six-month follow-up, the patient showed a complete recovery of her neurological functions with no remaining deficits. During the procedure, she experienced a brief period of vessel narrowing, but no other serious complications were reported.

Because this is a single case report, the evidence is limited and not yet enough to change standard medical practices. However, it highlights a specific procedure as a potential option for patients with severe complications after childbirth. Patients should discuss these specialized options with their medical team.

What this means for you:

A single case shows that a mechanical procedure may help some women with severe brain clots after giving birth.

Common questions

What is endovascular mechanical thrombectomy?

This is a procedure where doctors use tools like aspiration and stent-retrievers to physically remove blood clots from a vessel. In this case, it was used to open blocked veins in the brain. The procedure was successful in opening the veins for the patient who was 12 days postpartum.

Is this treatment safe for women after giving birth?

The patient in this report experienced a transient vasospasm during the procedure, but no other serious adverse events were reported. Because this is only one case, it is not enough to confirm the safety or effectiveness for all patients. You should talk to a doctor about specific risks.

How much recovery did the patient experience?

The patient experienced a complete neurological recovery without any remaining deficits at the six-month follow-up. This occurred after the successful opening of the blocked veins. However, because this is a single case, results may vary for other patients.

BackgroundCerebral venous sinus thrombosis (CVST) is a rare but potentially life-threatening complication of pregnancy and the postpartum period. Although systemic anticoagulation remains the standard first-line treatment, evidence supporting endovascular mechanical thrombectomy in postpartum patients is limited.Case presentationA 22-year-old woman presented 12 days after an uncomplicated vaginal delivery with progressive headache and vomiting. Neuroimaging confirmed extensive CVST involving the superior sagittal, cortical, left transverse, and sigmoid sinuses, extending to the left jugular bulb. An initially suspected bilateral parieto-occipital convexity subarachnoid hemorrhage was subsequently ruled out following further imaging review. Despite prompt anticoagulation with low-molecular-weight heparin, she developed rapid neurological deterioration with decreased level of consciousness. Following multidisciplinary evaluation, endovascular mechanical thrombectomy was performed using aspiration and stent-retriever techniques, achieving successful venous recanalization. The procedure was complicated by transient vasospasm, which resolved after intra-arterial milrinone administration. An extensive evaluation excluded inherited and acquired thrombophilia, autoimmune disease, malignancy, and infection, identifying the postpartum period as the most likely predisposing factor. The patient was discharged 12 days after the intervention with therapeutic anticoagulation and anti-seizure medication. At six-month follow-up, she demonstrated complete neurological recovery without residual deficits.ConclusionThis case highlights that endovascular mechanical thrombectomy may represent a valuable therapeutic option in carefully selected postpartum patients with extensive CVST who develop progressive neurological deterioration despite anticoagulation. Although current evidence remains limited, this report supports the role of a multidisciplinary approach and timely endovascular intervention in achieving favorable neurological outcomes.
