Postoperatively, the surgeons noted that the virtual reality models accurately represented the patients’ anatomy. They also reported that the models aided them in understanding the patients’ anatomy – indeed, this resulted in an alteration of the operative approach in over 60% of cases. Also of importance, patients reported that their preoperative anxiety regarding the procedure was quelled after they viewed the virtual reality models and gained a better understanding of their anatomy and the procedure.
In regards to specific instances of an alteration of the surgical approach, the presenter noted one example in which the virtual reality model revealed that the tumor was supplied superiorly by three arteries; this led the surgeon to perform his dissection moving caudo-cranially, so that he was able to dissect the avascular area of the tumor prior to clamping the renal artery.
The presenters acknowledged that objective operative outcomes are lacking from the current presentation, but indicated that they are in the process of acquiring these data.
