The results of this study will serve as a starting point for future trials concentrating on the effectiveness and clinical outcomes of the procedures performed in an office based angiosuite. Additionally, other studies could compare clinical outcomes between procedures performed in an office based angiosuite and other settings.

Endovascular surgery combined with the demands of patients and physicians for less invasive procedures, have make this type of surgery one of the most innovative fields in medicine. However the endovascular experience in an office-based angiosuite is different from that in a hospital suite, and has been viewed in the past by some physicians as unsafe because it lacks the safety net of immediate hospital resources. In 2005, medicine allowed endovascular procedures to be performed in the office setting. The results of this study will serve as a starting point for future trials concentrating on the effectiveness and clinical outcomes of the procedures performed in an office based angiosuite.
