Microsurgery

Background:

Microvascular free flaps are crucial in modern reconstructive surgery.
Standardized microvascular training is limited and costly.
Novel, accessible training methods are needed.

Purpose of the Study:

To assess if a short, reproducible course can impart microvascular skills.
To determine the predictive value of a pre-test for performance.
To investigate the influence of age on skill acquisition.

Main Methods:

A 3-5 hour pilot course was conducted for 30 participants (students, residents, surgeons) with no prior microvascular experience.
Participants performed two microanastomoses, evaluated for patency and time.
A pre-test was administered to assess predictive capabilities.

Main Results:

Over 50% of participants achieved patent microanastomoses within 2 hours.
Two-thirds of all attempted microanastomoses were patent.
The pre-test showed high specificity (100%) and PPV (100%) in identifying poor performers, while students and residents scored higher than surgeons.

Conclusions:

A brief, cost-effective, and reproducible microvascular anastomosis course can effectively train surgical skills.
The pre-test demonstrates potential for identifying individuals with lower aptitude.
This educational model can aid in selecting residents with natural talent for microvascular surgery.
