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.

Acute Appendicitis after Liver Transplantation: A Case Report and Review of the Literature.

Acute appendicitis is one of the most common etiologies for acute abdomen. However, fewer than 30 cases of acute appendicitis after liver transplantation have so far been reported in the literature. Previous case studies have concluded that acute appendicitis after liver transplantation may present differently than in non-immunosuppressed patients and thus may lead to more complications.

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.
