Japanese parturient body mass index and the role in initial nerve block height of women undergoing cesarean delivery with spinal anesthesia.

The present retrospective cohort study was designed to determine body mass index (BMI) at the delivery in women undergoing cesarean section in a Japanese urban area, and whether the nerve block height after spinal anesthesia upon the cesarean delivery relates to the lower maternal BMI, less gestational age, or underweight fetus at birth in the population.A total of 401 pregnant women undergoing cesarean delivery with spinal anesthesia were evaluated retrospectively. We examined background differences, including BMI at the delivery, gestational age, and fetal birth weight between the cases with and without the adequate initial nerve block height less than the sixth thoracic vertebral level (Th6) after the spinal dose administration.

Intraoperative real-time three-dimensional transesophageal echocardiography as a precise navigator for a successful complicated postoperative left ventricular pseudoaneurysm repair: a case report.

Background: Left ventricular pseudoaneurysm (LV-PAN) formation is a rare complication after cardiac surgery and mainly occurs after mitral valve surgery. Echocardiography plays a critical role in the assessment of rupture location, orifice geometry, and anatomical relationship with surrounding structures.

Case Presentation: A 56-year-old man presented with LV-PAN formation 1 year after aortic root replacement combined with aortic replacement despite the lack of direct manipulation of the rupture site in the procedure and postoperative myocardial infarction.
