“…Die Ausbildung an lebenden Versuchstieren (Rattenmodell) bietet die besten Voraussetzungen, um mikrochirurgische Techniken zu erlernen und auf einem hohen Niveau zu halten [3,7,12,14]. Die aufwendige Technik erfordert eine frühzeitige und subtile Einweisung des chirurgischen Assistenten in dieses operative Gebiet.…”

To optimise the microsurgical training in our clinic we organized a permanent possibility to practice microsurgical techniques of vascular anastomosis. This includes step-wise education by means of plastic materials, human placenta and the rat model. The most important role in this concept is played by the placenta. It supplies a realistic simulation of different in vivo situations concerning microvascular anastomosis. As to availability, handling and costs the placenta is superior to animal models and has replaced them almost completely in our educational concept.

Simple and viable in vitro perfusion model for training microvascular anastomoses

2004

In this report, we describe a novel in vitro perfused microvessel model for training microvascular anastomotic exercises. Arteries and veins with a diameter of ca. 1 mm were explanted from chicken wings. These vessels were cannulated at both ends and mounted on a platform. Preserved, expired whole blood obtained from the blood bank was continuously injected through the proximal catheter, using an automatic perfusor. This in vitro perfused microvessel model exactly simulated the viable small-animal vessels. The setting is very simply and reliably repeated; the materials used are very cheap and universally available. There are no ethical questions involved. Vessels explanted from the human placenta or omentum may be used in a similar manner to gain the "feel" of functioning human microvascular tissue. But such materials are rarer and require the approval of ethical committees.
