Latex balloons: an alternative, low-cost model for vascular anastomosis training in medical education

Simulators are increasingly being used in medical education, but accessibility is restricted by their elevated cost. A accessible and low-cost model was developed for teaching and learning vascular sutures and anastomoses at a Basic Surgical Techniques Laboratory. Latex balloons of varying colors, polypropylene 6.0 sutures, and other materials specifically for suturing (needle holder and forceps) were used. The balloons were fixed to screws inserted into wooden boards in order to facilitate repairs. E end-to-end, end-to-side, and side-to-side anastomoses and patching were performed. Anastomosis patency was tested by injecting water into one extremity of the balloon and observing the liquid exit via the opposite extremity. The advantages observed with this training model for anastomoses were malleability, resistance to passage of the suture, and the fact that it is inorganic. Latex balloons are an inexpensive option that are non‑perishable and offer prolonged use for teaching and practice of arterial sutures and anastomoses.
