A Novel Clinically Based Classification System for the Profunda Femoris Artery and the Circumflex Femoral Arteries.

Background: The profunda femoris artery (PFA) supplies important collateral branches to both the ipsilateral internal iliac artery and the distal superficial femoral artery (SFA). The size and patency of these collateral pathways can determine the risk of pelvic malperfusion, spinal cord ischemia, and lower extremity limb loss following vascular interventions. Despite its importance, the anatomy of the PFA is rarely characterized in clinical studies involving the pelvic or lower extremity circulation.

A proposed model for a comprehensive virtual subinternship in vascular surgery.

Objective: In the present study, we sought to understand the challenges, advantages, and applications of a vascular surgery virtual subinternship (VSI) curriculum.

Methods: Our institution hosted 25 students for two 4-week VSI rotations, one in July 2020 and one in August 2020. The students participated in a curriculum centered around the use of Zoom and telephone interactions with residents and faculty.

Aortic Transection after Blunt Abdominal Trauma in a Child.

Abdominal aortic injury secondary to blunt abdominal aortic trauma (BAAI) is rare in children but frequently occurs in association with other injuries, including bowel injury and vertebral fracture. We present a case of a 14-year-old boy who sustained a partial transection of the infrarenal aorta with a lumbar chance fracture and small bowel injury after a motor vehicle accident. Repair was performed with bowel resection followed by Dacron graft interposition.
