NCT00318279

Brief Summary

To determine if practicing an aorto-saphenous vein anastomosis on a low-fidelity surgical simulator allows trainees to produce a higher quality anastomosis in a shorter period of time, than a group that only learns by watching a video.

Outcome Measures

Primary Outcomes (1)

  • Quality of final vascular anastomosis based on validated scale

Secondary Outcomes (5)

  • Global rating of operative skill based on validated scale (final anastomosis)

  • Time taken to complete final anastomosis

  • Time taken to complete initial and final anastomosis (experimental group only)

  • Anastomotic leakage for final anastomosis

  • Anastomotic patency for final anastomosis

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • st year surgical resident at The University of Western Ontario
  • Anastomosis naive - the subject must not have performed a human vascular anastomosis in the past (it is acceptable if they have observed one being performed in the past)

You may not qualify if:

  • Completed a human vascular anastomosis as the primary operator/surgeon in the past
