Cardiac disease is one of the leading causes of maternal mortality in developed countries. The presence of a mechanical valve is a predictor of cardiac complications in obstetric patients, likely due to the challenges associated with pregnancy hypercoagulability and the imperative of meticulous management of anticoagulation throughout pregnancy, delivery, and the postpartum and to prevent the devastating event of a mechanical valve thrombosis. We report on the management of a pregnant woman with a mechanical aortic valve found to have a thrombus at 37 weeks gestation. It was decided to perform cesarean delivery to allow for a reoperative mechanical aortic valve replacement 24 hours thereafter.

Sacroiliac joint pain is one of the most common causes of low back pain in pregnant women. We present a case of a 30-year-old G2P1 at 20 weeks gestation presenting with intractable low back pain refractory to conservative management. ⋯ We elected to do an ultrasound-guided sacroiliac joint injection that significantly abated her pain. This article aims to review the diagnosis, pathophysiology, and treatment approaches to adequately manage sacroiliac joint pain in pregnant women.

Case Reports
Neuraxial Anesthesia in a Patient With a History of Spontaneous Intracranial Hypotension: A Case Report.
One commonly cited complication of neuraxial techniques is postdural puncture headache. Patients with spontaneous intracranial hypotension may present with a similar constellation of symptoms in the absence of any neuraxial instrumentation. The underlying physiology of spontaneous intracranial hypotension is similar to postdural puncture headache, but cerebrospinal fluid leaks may develop spontaneously at multiple levels of the neuraxis due to a variety of proposed mechanisms. We present a patient with a history of spontaneous intracranial hypotension who underwent a total knee arthroplasty under spinal anesthesia without complication and discuss the pathophysiology, proposed etiologies and treatments, and safety of neuraxial anesthesia in spontaneous intracranial hypotension.

Costello syndrome is a rare genetic disorder characterized by mental and growth retardation and distinctive coarse facies. A significant proportion of patients with Costello syndrome have hypertrophic cardiomyopathy, papillomata, and malignant tumors. ⋯ There have been several reports on the anesthetic management of children with Costello syndrome, but few have reported on the anesthetic management of adults with Costello syndrome. In adults, careful preoperative evaluation as well as preparation for adult-onset and previously unrecognized medical conditions are key for safe anesthetic management.

Amniotic fluid embolism is a rare but dreaded complication of pregnancy, with an incidence between 2 and 7/100,000 deliveries. We report an amniotic fluid embolism after urgent cesarean delivery diagnosed on a cardiac arrest, complicated by cardiogenic shock and acute respiratory distress syndrome. This report describes the indication, efficacy, and success of venoarterial extracorporeal membrane oxygenation in the early management of cardiac arrest, cardiac failure driven by amniotic fluid embolism, and acute respiratory distress syndrome. The use of venoarterial extracorporeal membrane oxygenation support after recovery from cardiac arrest after amniotic fluid embolism should be considered early during the management of these cases.
