Factor XI deficiency is predominantly found in the Ashkenazi Jewish population with a prevalence of 9%, but also seen in other ethnicities. Little information is available on obstetric anesthesia management in women with Factor XI deficiency. Therefore, we undertook a study to evaluate obstetric, anesthetic and perinatal outcomes in parturients with Factor XI deficiency. ⋯ This study is the first step in building a national database for anesthetic cases and outcomes of parturients with Factor XI deficiency. Further efforts must be made to provide safe analgesia for these women.

Inferior vena cava compression syndrome (VCCS) is a serious complication of supine fetal magnetic resonance imaging (MRI) examinations, particularly during late gestation. This morphologic study correlated the occurrence of VCCS with the grade of inferior vena cava (IVC) compression. ⋯ The presented data support the concept of physiologic compensation for significantly reduced venous backflow in the supine position during the second and third trimesters of pregnancy.
