Aortic balloon occlusion in distal zone 3 reduces blood loss from obstetric hemorrhage in placenta accreta spectrum.

Background: Peripartum hemorrhage is a significant cause of maternal death. We developed a standardized, multidisciplinary cesarean hysterectomy protocol for placenta accreta spectrum (PAS) using prophylactic resuscitative endovascular balloon occlusion of the aorta (REBOA). We initially placed the balloon in proximal zone 3, below the renal arteries.

Percutaneous vertebroplasty in patients with spinal canal compromise.

Objective: The American College of Radiology Standard for Performance of Percutaneous Vertebroplasty lists as relative contraindications to the procedure conditions causing "significant spinal canal compromise." We believe percutaneous vertebroplasty can be performed safely and efficaciously in individuals without radicular symptoms who present with canal compromise, with or without cord compression.

Materials And Methods: We reviewed all vertebroplasties performed at our institution over the past 4 years.
