Introduction to Microsurgical Techniques

Wednesday, 1 July 2020, 08:30 - 17:45
This theory and practical 1 day course is designed to give delegates a basic understanding and experience with general microsurgical / vascular techniques. This course is sponsored by Freelance Surgical Ltd. 

Course Information

This is the second edition of the course “Introduction to Microsurgical Techniques” at the ECVS meeting. The course is designed to give delegates a basic understanding and experience with general microsurgical / microvascular techniques. This course will be divided into a theoretical and a practical session using various low-fidelity models and fresh cadaveric tissues. A larger portion of the course will be spent working with microscopes. This year, the course will take place in a State-of-the-Art Surgery Research and Education center located in central Valencia, the Centro de Investigacion Principe Felipe (CIPF, http://www.cipf.es)

The Theoretical Session
The theoretical session will review common indications for microsurgery in veterinary patients, use of magnification in the form of loupes and operating microscopes, basic instrumentation, ergonomy, and microsurgical suturing techniques.

Practical Session
The practical session will allow delegates to practice several techniques including simple linear suturing, end-to-end anastomosis, and end-to-side anastomosis using low-fidelity models and fresh cadaveric tissue and micro-suture material. All practical exercises will be performed using magnifying surgical loupes and operating microscopes. Delegates are welcome to bring their own loupes, otherwise surgical loupes (4x magnification) will be provided.
 
      
 

At the end of the course, each delegate should be able to:

  • Close a linear defect in a vessel and ureter using a simple-interrupted and simple-continuous suture pattern
  • Perform an end-to-end anastomosis of a 2-3 mm diameter vessel or ureter using a simple-interrupted and simple-continuous suture pattern
  • Perform an end-to-side anastomosis of a 2-3 mm diameter vessel or ureter using a simple-continuous pattern
  • Understand the basic instrumentation and techniques for use of microvascular coupling devices

Practical session (dry lab)

• Introduction to the use of a microscope / surgical loupes - fitting and adjustment for maximum clarity.
• Demonstration of specific instrumentation used in the lab and proper handling techniques - locking vs non locking jaws, pencil grip, ergonomic suturing angle, etc.
• Demonstration of proper posture and hand position for loupes and microscope.
• Demonstration of specific suturing techniques that are different from traditional tissue handling and suturing - grasping vessel edges with forceps, grasping suture with instruments, use of surgeons throw, use of short suture tails, number of throws per knot, switching hands for grasping the free end of the suture, in-to-out vs out-to-in, etc.
• Suturing on a grape – simple-interrupted suture pattern.
• Simple arteriotomy - linear incision closure using simple-interrupted pattern in different orientation angles.
