Hybrid modeling techniques for 3D printed deep inferior epigastric perforator flap models.

Background: Deep Inferior Epigastric Perforator Flap (DIEP) surgical procedures have benefited in recent years from the introduction of 3D printed models, yet new technologies are expanding design opportunities which promise to improve patient specific care. Numerous studies, utilizing 3D printed models for DIEP, have shown a reduction of surgical time and complications when used in addition to the review of standard CT imaging. A DIEP free flap procedure requires locating the inferior epigastric perforator vessels traversing and perforating the rectus abdominis muscle, perfusing the abdominal skin and fatty tissue.

Optimus covered stent: Advanced covered stent technology for complex congenital heart disease.

Aim: To assess the acute results of the first human use of the Optimus covered stent in complex coarctation of the aorta.

Methods And Results: We successfully implanted the Optimus covered stent in eight cases in patients whose preprocedural anatomy looked challenging for currently available covered stents. Six of the patients had native coarctation with one recoarctation following surgical repair.

Removal of Vagus Nerve Stimulator Leads and Reuse of Same Site for Reimplantation: Technique and Experience.

Objective: This report describes the authors' experience and technique in removing vagus nerve stimulator leads, including coils, and reuse of the same site on the vagus nerve for implantation of new coils.

Methods: The charts of all patients who underwent complete removal by the authors of vagus nerve stimulator leads between 1 September 2001 and 1 July 2015 were retrospectively reviewed.

Results: Thirty patients underwent 31 surgeries for removal of vagus nerve stimulator leads.
