Endoluminal approaches to treating vascular disease involve the insertion of a prosthetic device into the vasculature through a small, oen percutaneous, access site created in a remote vessel, followed by the intraluminal delivery and deployment of a prosthesis via transcatheter techniques (Veith et al., 1995). In contrast to conventional surgical therapies for vascular disease, the use of transluminally placed endovascular prostheses are distinguished by their “minimally invasive” nature. Because these techniques do not require extensive surgical intervention, they have the potential to simplify the delivery of vascular therapy, improve procedural outcomes, decrease procedural costs, reduce morbidity, and broaden the patient population that may benet from treatment. Not surprisingly, endoluminal therapies have generated intense interest within the vascular surgery, interventional radiology, and cardiology communities over recent years.
Image-Guided Surgery
Published in John G Webster, Minimally Invasive Medical Technology, 2016
The identification of relevant anatomic structures requires image segmentation algorithms (see chapter 10) and often manual image processing (Kikinis et al 1996). The resulting three-dimensional information can be used for orthopedic planning (e.g. optimal prosthesis placement), optimized shapes of stent grafts for the individual patients in vascular surgery (Shahidi et al 1998), etc. Representation of multiple imaging modalities in one model requires image mapping, fusion and visual clues on the different information contained. This can be accomplished, for example, by different color tables or by selective visualization. With present technology it is even possible to generate stereoscopic 3D displays and holograms that allow 3D exploration of the data. Chapter 13 describes some of these techniques in more detail.

The role of nanomaterials and nanostructured surfaces for improvement of biomaterial peculiarities in vascular surgery: a review

The goal of angiology and vascular surgery is to repair or replace the damaged vessels with similar tissue, which can reproduce the properties of the original vessel and avoid short and long term stenosis, thrombosis, leakage or rupture (Bordenave, Menu, and Baquey 2008).
