Radiation-Induced DNA Damage in Operators Performing Endovascular Aortic Repair

Circulation, 2017
Background: Radiation exposure during fluoroscopically guided interventions such as endovascular aortic repair (EVAR) is a growing concern for operators. This study aimed to measure DNA damage/repair markers in operators perfoming EVAR.

Novel Drug‐Testing Platform for Vascular Injury‐induced Intimal Hyperplasia Using a Microphysiological System

Advanced Healthcare Materials, EarlyView.
This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

In Situ Laser Fenestration Is a Feasible Method for Revascularization of Aortic Arch During Thoracic Endovascular Aortic Repair

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2017
Background Reconstruction of the aortic major branches during thoracic endovascular aortic repair is complicated because of the complex anatomic configuration and variation of the aortic arch.

Uniting 4D Printing and Melt Electrowriting for the Enhancement of Regenerative Small Diameter Vascular Grafts

Advanced Healthcare Materials, EarlyView.
A hybrid 4D printing strategy enables the fabrication of shape‐morphing, mechanically reinforced tubular constructs for vascular tissue engineering. By combining alginate‐methylcellulose hydrogels with melt electrowritten polycaprolactone fibers and protein‐based functionalization, this platform supports spatially organized co‐cultures of fibroblasts ...

Thoracic Endovascular Aortic Repair of Esophageal Cancer-Associated Aortoesophageal Fistula: A Case Report and Literature Review

Case Reports in Oncological Medicine, 2018
Background Thoracic endovascular aortic repair of an aortoesophageal fistula is an effective emergency treatment for patients with T4-esophageal cancer, as it prevents sudden death, and is a bridge to surgery.

Endovascular aortic repair

Cardiologia Croatica, 2016
U Klinickom bolnickom centru Rijeka je u razdoblju od 2014. do 2016. godine ucinjeno ukupno 49 endovaskularnih zahvata (TEVAR 20, EVAR 29). U 14 bolesnika (28, 6%) zahvat je hitno izveden zbog AAS. Vecina procedura ucinjena je perkutano (30 bolesnika, 61%).

A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

Advanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

Development of a Modular Ribonucleoprotein Complex as a General Strategy to Deliver RNAi Therapeutics

Advanced Healthcare Materials, EarlyView.
A modular and customizable RNAi therapeutics delivery platform composed of a pseudosymmetric human RNA binding protein‐siRNA complex (SmiRNP) is developed. By fusing a targeting module and an endosomal escape peptide onto the delivery platform, SmiRNP successfully delivered siRNA to silence the KRAS oncogene in a colorectal carcinoma cell line, leading
