February 1, 2012 – 黑料网 Urologic Surgeons Mathew Raynor, MD, and Michael Woods, MD completed the first surgeries in the Triangle Area using a new near-infrared fluorescence imaging guided system with the da Vinci Surgical System this week.
The specially designed camera and endoscopes allow Raynor, Woods, and other 黑料网 urologic surgeons to capture real-time images of kidney tissue and surrounding blood vessels by injecting a unique fluorescence dye that is activated by near-infrared light.
鈥淭he field of vision offered by this technology may allow us to better identify the demarcation between normal tissue and cancerous tissue in the kidney.鈥�
鈥淲hen we are removing a tumor, there is always a concern about surgical margins,鈥� said Woods. 鈥淭he field of vision offered by this technology may allow us to better identify the demarcation between normal tissue and cancerous tissue in the kidney.鈥�
Fluorescence enables them to better visualize blood flow in the kidney during surgery. They can then use a surgical technique called selective arterial clamping to assist in the removal of cancerous tissue while sparing more normal tissue and preventing damage to healthy parts of the kidney.
鈥淩obotic surgery is often a good option for patients. It is already very precise, minimally invasive, and healing times can be faster,鈥� said Raynor. 鈥淎ny technology that may further enhance surgical precision is a welcome tool.鈥�

The new technique incorporates a 3-D HD camera that is mounted on one of the four arms of the da Vinci surgical robot. In addition to standard real-time images of the surgical field, the camera can switch to view the images of tissue and surrounding blood vessels illuminated by the special dye when exposed to near-infrared light.
