    2. Systems, methods and apparatuses for real-time anastomosis guidance and surgical evaluation using optical coherence tomography

      Systems, methods and apparatuses for real-time anastomosis guidance and surgical evaluation using optical coherence tomography
      A surgical evaluation and guidance system for use in extravacular evaluation and guidance of fluid vessel surgeries, includes an optical coherence tomography engine; a vessel probe optically coupled to the optical coherence tomography engine; and a signal processing and display system adapted to communicate with the optical coherence tomography engine to receive imaging signals therefrom. An optical coherence tomography vessel probe for use in extravacular evaluation and guidance of fluid ...

    3. Evaluation of Microvascular Anastomosis Using Real-Time, Ultra-High-Resolution, Fourier Domain Doppler Optical Coherence Tomography

      Evaluation of Microvascular Anastomosis Using Real-Time, Ultra-High-Resolution, Fourier Domain Doppler Optical Coherence Tomography
      Background: Evolution in microsurgical techniques and tools has paved the way for supermicrosurgical anastomoses, with vessel diameters often approaching below 0.8 mm in the clinical realm and even smaller (0.2 to 0.3 mm) in murine models. Several imaging and monitoring devices have been introduced for postoperative monitoring, but intraoperative guidance, assessment, and predictability have remained limited to binocular optical microscopy and the surgeons experience. The authors present ...

    4. In Vivo Real-time Ultra-fast 3D Fourier Domain Optical Coherence Tomography Imaging of Anastomoses for Super-microsurgical Research

      In Vivo Real-time Ultra-fast 3D Fourier Domain Optical Coherence Tomography Imaging of Anastomoses for Super-microsurgical Research
      PURPOSE: The emergence of supermicrosurgery has enabled reconstructive surgery to enter into a new era by advancing a series of novel techniques including lymphaticovenous anastomosis, fingertip replantation, and perforator flap surgery. Nonetheless, super-microsurgery techniques impose great technical challenges. The instant monitoring and evaluation of the patency of the anastomosis, in particular of intraluminal structure, is critical to be able to predict the necessity of early re-intervention and thus reduce/avoid ...

    5. Microvascular anastomosis guidance and evaluation using real-time three-dimensional Fourier-domain Doppler optical coherence tomography

      Microvascular anastomosis guidance and evaluation using real-time three-dimensional Fourier-domain Doppler optical coherence tomography
      Vascular and microvascular anastomoses are critical components of reconstructive microsurgery, vascular surgery, and transplant surgery. Intraoperative surgical guidance using a surgical imaging modality that provides an in-depth view and three-dimensional (3-D) imaging can potentially improve outcome following both conventional and innovative anastomosis techniques. Objective postoperative imaging of the anastomosed vessel can potentially improve the salvage rate when combined with other clinical assessment tools, such as capillary refill, temperature, blanching, and ...

    6. Real-time three-dimensional Fourier-domain optical coherence tomography video image guided microsurgeries

      Real-time three-dimensional Fourier-domain optical coherence tomography video image guided microsurgeries
      The authors describe the development of an ultrafast three-dimensional (3D) optical coherence tomography (OCT) imaging system that provides real-time intraoperative video images of the surgical site to assist surgeons during microsurgical procedures. This system is based on a full-range complex conjugate free Fourier-domain OCT (FD-OCT). The system was built in a CPU-GPU heterogeneous computing architecture capable of video OCT image processing. The system displays at a maximum speed of 10volume ...
