Title : Three-dimensional reconstruction in liver surgery: A feasible reality in clinical practice
Abstract:
Three-dimensional reconstruction of CT and MRI is now becoming a frequent option to visualize clinical images with direct volume rendering software. Unfortunately, this kind of rendering doesn’t allows the reconstruction of a single organ to manipulate it in clinical practice. On the other hand, further evolution of this technology have proposed augmented reality systems. However, the deformation and displacement of the organs as observed during a surgical intervention remain a problem for their applicability. For this reason three-dimensional reconstruction of radiologic images remains a challenge for many surgeons due to the relative lack of widespread utilization as well as the availability of relevant resource materials. The main question remains how to apply the three-dimensional reconstruction in clinical practice with low cost or free software. There is no doubt about the various advantages that may be obtained fallowing its use, particularly in liver surgery. Its utilization allows a new way of surgical thinking in term of planning the intervention, in comprehension of complex liver anatomy and its intraparenchimal variation, in improving comprehension of intraoperative ultrasound, in planning the preferable section plan employing intraparenchimal structures as landmark for resection, in facilitating intraoperative decision making and sharing intuitive understanding in the surgical staff. We present some examples of its usage, starting from manipulation and editing of three-dimensional reconstruction to its application during intervention, demonstrating how this technology could be easy available in daily practice.
