Abstract
Surgical education has evolved over time to incorporate supplemental modalities of training beyond the operating room. Even with the utility of simulation software and didactic education, there is still a need to provide surgical residents with experience in live tissue dissection and tissue handling while maintaining patient safety. In our program, after two clinical years, residents participate in a year of translational research which uses porcine models for complex open abdominal procedures. During the porcine surgeries, our residents are guided by the supervising attending to perform key portions of the procedure typically reserved for those more senior trainees. We found in a survey that research residents after two clinical years found this experience with large animal surgeries helped them better navigate anatomic structures and would recommend this to future trainees. We believe this dual-purpose research-training model provides a valuable resource that can be adapted to other programs.

Abstract
Endovascular intervention for occlusive arterial trauma is becoming more common in clinical practice. The aim of this study is to present an ovine model of extremity arterial injury for use in future endovascular translational research. Animals under general anesthesia had their left superficial femoral artery exposed, which was bluntly injured over a 2-cm section using a hemostat and injection of air. Occlusion was confirmed on angiography and the flow characteristics measured by ultrasonography. Of five animals enrolled, four occluding lesions were created successfully. Post injury, there was a significant reduction in the median (interquartile range) systolic velocity (cm/sec) on the left (injury) compared to the right (control) side (3.5 (0-16.5) vs. 29 (23.8-43.3); p < 0.001). The ovine superficial femoral artery can be used to consistently produce an occlusive lesion that is suitable for use in the future evaluation of endovascular trauma interventions.
