This is a very common question we get from OB/GYN faculty. We found no difference in the risk for stroke regardless of delivery type.
New Study Shows Moyamoya Disease Patients Are Not at an Increased Risk of Stroke When Giving Birth Vaginally
Moyamoya disease (MMD) is a rare, progressive disorder that can lead to strokes. David J. Altschul, MD, Director of Neurovascular Surgery; Co-Director of Montefiore Comprehensive Stroke Center; Assistant Professor of Neurological Surgery; Associate Professor, Department of Radiology, Albert Einstein College of Medicine, wanted to investigate whether giving birth vaginally or by cesarean section put women with the disease at a higher risk of having a stroke.
That study, published in the April 2022 issue of the journal World Neurosurgery showed that for pregnant MMD patients, there is no increased risk of stroke from either a vaginal or C-section delivery.
The researchers evaluated the National Inpatient Sample database for the years 2013–2018 to determine if vaginal delivery increased the risk of a stroke. They found no evidence that either vaginal delivery or C-sections are risk factors for pregnant patients with MMD.
“That means it is OK for a pregnant patient suffering with MMD to have a vaginal delivery,” said Dr. Altschul.
