How should suspected stroke in pregnancy be evaluated and managed?

• A. Similar to non-pregnant protocols with obstetric collaboration; imaging to minimize fetal exposure; tPA may be considered if benefits outweigh risks; BP management accordingly.
• B. Immediate cesarean delivery before stroke treatment.
• C. Avoid imaging entirely to protect fetus.
• D. Treat only after pregnancy ends.

Answer: (A)

Suspected stroke in pregnancy is an emergency managed with the same urgency as for nonpregnant patients, but with two important adjustments: protect the fetus through careful imaging choices and maintain close collaboration with obstetrics. Start with rapid imaging to determine stroke type. A non-contrast head CT is used first to rule out hemorrhage because it’s fast and widely available. If there’s no bleed and an ischemic stroke is suspected, MRI can provide detailed information with minimal fetal radiation exposure, and vascular imaging (CT angiography or MR angiography) can be added when it will change management, using shielding and the lowest effective doses. Contrast use is weighed carefully, with iodinated contrast for CT angiography generally acceptable if the benefits outweigh risks; gadolinium is avoided unless essential. If an ischemic stroke is confirmed, reperfusion therapy may be pursued when the benefits to the mother outweigh any fetal risks. Intravenous thrombolysis can be considered in pregnancy within standard criteria, with vigilant blood pressure management and obstetric input. Keep blood pressure at levels that support cerebral perfusion while reducing the risk of hemorrhagic transformation. For large vessel occlusions, mechanical thrombectomy is a viable option with multidisciplinary coordination. Delaying treatment for cesarean delivery, avoiding imaging, or waiting until after pregnancy to treat would miss timely therapy and harm outcomes. The best approach is to treat promptly with a plan that protects both mother and fetus through collaboration and appropriate imaging and therapy choices.
