Moist-condition Training for Cerebrovascular Anastomosis: A Practical Step after Mastering Basic Manipulations

Area of Science:

• Neurosurgery
• Surgical Training
• Microsurgery

Background:

• Cerebrovascular anastomosis requires precise manipulation in moist surgical conditions.
• Current training often occurs in dry environments, not fully preparing surgeons for operational challenges.
• Difficulties include poor lumen visibility and suture handling in wet fields.

Purpose of the Study:

• To develop and evaluate a simple, practical moist-condition training method for cerebrovascular anastomosis.
• To assess the effectiveness of this training in improving surgical performance and reducing errors.
• To bridge the gap between dry-condition training and actual surgical procedures.

Main Methods:

• A novel training model using chicken wing arteries in a water-filled container was developed.
• Trainees performed end-to-side anastomoses under magnification, simulating surgical difficulties.
• Retrospective comparison of 100 wet-condition vs. 100 dry-condition training sessions and clinical cases.

Main Results:

• Moist-condition training sessions were longer with a higher incidence of wrong stitches compared to dry sessions.
• However, after implementing moist-condition training, superficial temporal artery to middle cerebral artery bypass surgery time decreased significantly.
• The incidence of wrong stitches in actual surgeries also showed a trend of reduction post-training.

Conclusions:

• The developed moist-condition training method is a useful and practical tool for surgical education.
• It effectively prepares surgeons for the challenges of performing anastomosis in wet environments.
• This training serves as a crucial bridge to enhance proficiency in complex cerebrovascular surgeries.
