Acute revascularization therapy in pregnant patients

Area of Science:

• Neurology
• Obstetrics
• Cardiovascular Medicine

Background:

• Ischemic stroke during pregnancy is rare but poses complex treatment challenges.
• Acute revascularization therapies, such as rt-PA, are effective for stroke but their use in pregnancy is debated.
• Limited data exists on the safety and efficacy of these treatments in pregnant patients.

Purpose of the Study:

• To evaluate the outcomes of acute revascularization therapy in pregnant patients with ischemic stroke.
• To determine if pregnancy is a contraindication for treatments like rt-PA.
• To review the existing evidence on maternal and fetal safety.

Main Methods:

• A systematic review of 16 patients who underwent acute revascularization therapy during pregnancy.
• Analysis of maternal and fetal outcomes, including complications and survival rates.
• Review of treatment strategies, including rt-PA and endovascular approaches.

Main Results:

• The systematic review included 16 pregnant patients with a mean age of 31.7 years.
• Good maternal outcomes were observed in 77.8% of cases.
• Fetal outcomes were positive in 56.3% of cases, indicating potential benefits.
• Hemorrhagic complications were noted, suggesting the need for careful consideration of treatment approaches.

Conclusions:

• Pregnancy itself is not an absolute contraindication for acute revascularization therapy in ischemic stroke.
• Intravenous rt-PA can yield favorable maternal and fetal outcomes.
• Endovascular approaches may reduce hemorrhagic risks, and treatment decisions require consideration of facility capabilities and obstetric collaboration.
