Retrograde Femoral Access Flipped Antegrade Technique and its Effect on Patient Outcomes Following Lower Extremity Angiography.

Background: Common femoral artery access is a critical step in the endovascular treatment of peripheral artery disease. Traditionally, access is obtained either by a retrograde approach from the contralateral leg with an "up-and-over" aortic bifurcation technique, or in an antegrade fashion in the ipsilateral leg. Retrograde arterial access flipped antegrade in the ipsilateral femoral artery incorporates the technical ease of retrograde access (RA) with mechanical advantages of antegrade access (AA).

Characterization and management of type II and complex endoleaks after fenestrated/branched endovascular aneurysm repair.

Introduction: Endoleaks are more common after fenestrated/branched endovascular aneurysm repair (F/B-EVAR) than infrarenal EVAR secondary to the length of aortic coverage and number of component junctions. Although reports have focused on type I and III endoleaks, less is known regarding type II endoleaks after F/B-EVAR. We hypothesized that type II endoleaks would be common and often complex (associated with additional endoleak types), given the potential for multiple inflow and outflow sources.

Fiber Optic RealShape technology in endovascular surgery.

Fiber Optic RealShape technology is a new endovascular guidance system that aims to simplify endovascular procedures by improving wire, catheter, and device visualization, while reducing reliance on ionizing radiation. Developed by Philips, the system uses light refracted through optical fibers to generate real-time renderings of wires and catheters in three-dimensional space. Currently, devices with embedded Fiber Optic RealShape technology are being studied in human patients undergoing endovascular procedures.

Liver ex situ machine perfusion preservation: A review of the methodology and results of large animal studies and clinical trials.

Ex vivo machine perfusion (MP) is a promising way to better preserve livers prior to transplantation. Currently, no methodology has a verified benefit over simple cold storage. Before becoming clinically feasible, MP requires validation in models that reliably predict human performance.
