Three-dimensional ultrasound volume and conventional ultrasound diameter changes are equally good markers of endoleak in follow-up after endovascular aneurysm repair.

Introduction: The main disadvantages of computed tomography angiography (CTA) in follow-up after endovascular aneurysm repair are the risks of contrast-induced renal impairment and radiation-induced cancer. Three-dimensional ultrasound is a new technique for volume estimation of the aneurysm sac. Some studies have reported promising results.

Contrast-enhanced ultrasound detects type II endoleaks during follow-up for endovascular aneurysm repair.

Objective: Repeated computed tomography angiography (CTA) can be used during follow-up visits for endovascular aneurysm repair (EVAR) but leads to accumulated radiation exposure and may cause renal impairment. Therefore, the use of contrast-enhanced ultrasound (CEUS) has increased, and its ability to detect endoleaks has been promising. The aim of this study was to investigate the diagnostic accuracy of CEUS vs CTA for endoleak detection during EVAR follow-up.

Corrosion and metal release from overlapping arterial stents under mechanical and electrochemical stress - An experimental study.

Intra-arterial stenosis due to atherosclerosis is often treated with endovascular balloon dilatation with a metal stent. Restenosis is common and is frequently treated with a new stent placed inside the existing one or the stents are placed with overlap to cover a larger area of the vessels. Observations of stent fractures, stent compression, accumulation of immunocompetent cells around stents have suggested the possibility of immunologic reactions to substances released from stents.

HbA1c predicts long-term postoperative mortality in patients with unknown glycemic status at admission for vascular surgery: An exploratory study.

Background: Peripheral arterial disease (PAD) and diabetes mellitus (DM) represent major public health challenges and are tightly associated. To facilitate early diagnosis, HbA1c has been implemented as the preferred diagnostic tool for the diagnosis of type 2 DM. In this study, we compared and evaluated HbA1c, fasting plasma glucose (FPG), and 2-hour post-load glucose values to determine which test best predicted mortality in patients with PAD.
