A 68-year-old man was scheduled for mediastinal tumor resection. Aortic invasion was unclear on preoperative computed tomography. ⋯ An endovascular stent graft was placed in the distal arch to protect the aorta, but excessive bleeding occurred from the aortic defect on tumor removal. This case shows that massive hemorrhage can occur during the resection of an aorta-invading tumor despite the use of an endovascular stent graft.

As a step toward understanding whether learning preferences may benefit trainees and instructors, we studied the learning preferences, based on the VARK questionnaire, of anesthesiology residents during their orientation month to determine whether knowing their preferences influenced the educational resources they used. While resource utilization was similar for residents who knew their preferences and those who did not, residents overall used aural and read/write resources frequently. The learning preferences of 13 residents (72.2%) changed during the month. While further research is needed, this study provides insight into anesthesiology residents' learning styles.

Intraoperative cortical and subcortical bipolar or monopolar mapping is the gold standard for neurosurgical procedures that involve lesions near functional or "eloquent" cortex. However, the classic Penfield stimulation has a higher intraoperative seizure rate than high-frequency short-train stimulation. ⋯ However, seizure-free mapping cannot be guaranteed even with high-frequency stimulation particularly at high current thresholds. We encountered a case of severe generalized tonic-clonic seizure and consequent severe brain bulge in an 8-year-old child during cortical mapping with the high-frequency protocol.

Ultrasound-Guided Midpoint Transverse Process to Pleura Block in Breast Cancer Surgery: A Case Report.
To avoid the safety issues related to thoracic paravertebral blocks, we performed midpoint transverse process to pleura blocks in 3 patients before general anesthesia for modified radical mastectomies. The midpoint transverse process to pleura blocks served as the major component of multimodal analgesia. ⋯ We noted decreased sensation to cold and pinprick from T2 to T8 dermatome level with sparing of axilla and infraclavicular areas. The maximum pain numeric rating scale score (0-10) was 4 out on movement and none had mean 24-hour numeric rating scale >3.

Type 3 von Willebrand disease is a rare and severe inherited bleeding disorder that carries an elevated risk for epidural and spinal hematoma as well as pregnancy-associated complications. Neuraxial anesthesia in these patients is controversial but may be considered if the parturient has received appropriate factor replacement. We present the case of a woman with type 3 von Willebrand disease and a severe bleeding history that underwent successful spinal anesthesia during successive cesarean deliveries. Our case highlights the importance of early multidisciplinary consultation and advance planning in the care of these rare events.
