Peripheral Arterial Endovascular Procedures Performed in a Non-Hospital-Based Facility by First-Year Vascular Surgery Fellows

Abstract

Objective: Traditionally, vascular surgery fellows (VSFs) have learned to perform peripheral arterial endovascular procedures in a hospital setting. Many vascular surgeons currently perform these procedures in an “outpatient” non-hospital-based setting. Loss of these cases from the hospital setting may impact vascular surgery fellowship endovascular volume. We assessed the safety of first-year VSFs performing peripheral endovascular procedures under the supervision of vascular surgery attending surgeons in a non-hospital-based facility. Methods: Between January 1, 2012, and December 31, 2016, 166 patients underwent 193 endovascular procedures in a non-hospital-based ambulatory facility: 136 interventions (65 femoral, 40 iliac, 13 popliteal, and 9 infrapopliteal arteries) and 31 diagnostic arteriograms for claudication (57.8%; 85), rest pain (11.6%; 17), tissue loss (12.9%; 19), and failing grafts (17.7%; 26). Interventions included balloon angioplasty alone in 8.8% (12/136) of cases, stents in 16.9% (23/136), covered stents in 14% (19/136), atherectomy in 60.3% (82/136), and mechanical thrombolysis in 0.7% (1/136). Results: First-year VSFs performed an increasing percentage of these procedures during this interval: academic year 2012 to 2013 = 0% (0/49), 2013 to 2014 = 31% (17/54), 2014 to 2015 = 93% (56/60), and 2015 to 2016 = 82% (57/70). All but 5 (3%) patients having 167 procedures were discharged home after 2 to 6 hours of bed rest without any 30-day adverse outcomes. Four patients were immediately transferred to our hospital after the intervention: 2 for respiratory issues (hypoxia), 1 for groin hematoma (observation only), and 1 for arterial occlusion (required tibial stent not available at outpatient center). One patient returned to our hospital with rest pain due to treatment site occlusion the following day. Conclusion: Our results demonstrate that complex peripheral arterial endovascular procedures can be performed safely by first-year VSFs under vascular attending supervision in an outpatient, non-hospital-based setting.
