Omniflow prosthesis for treatment prosthetic graft infection of the aorto-iliac and femoropopliteal level on the infrarenal aortic segment and lower extremity.

Objectives: To report outcomes after the use of the Omniflow II biosynthetic graft (LeMaitre Vascular, Il, USA) for vascular reconstruction in patients with prosthetic infection at the aorto-iliac and femoropopliteal level.

Methods: Within a six-year period, all consecutive patients with aorto-iliac and femoro-popliteal graft infection treated by resection of the infected graft material, extensive local debridement and reconstruction using Omniflow II biosynthetic graft were retrospectively analzyed. Patient characteristics, intraoperative details, postoperative outcomes, and infection details were assessed.

Management of Non-A Non-B Aortic Dissection: A Narrative Review.

Non-A non-B aortic dissection remains a complex and controversial topic in cardiovascular management, eliciting varied approaches among cardiologists and surgeons. Due to the limited evidence surrounding this condition, existing guidelines are limited in the complexity of their recommendations. While most patients are initially managed medically, invasive treatment becomes necessary in a large proportion of patients.

Are current follow-up intervals justified in patients with non-emergent aortic surgeries?

Objectives: Evidence for different surveillance protocols following aortic treatment is still lacking. The aim of this study was to analyse the clinical relevance of a first follow-up visit after 6 months.

Methods: Between January 2018 and December 2019, 464 patients treated for non-emergent aortic pathologies were retrospectively analysed.

Microstructure-Informed Myelin Mapping (MIMM) from routine multi-echo gradient echo data using multiscale physics modeling of iron and myelin effects and QSM.

Purpose: Myelin quantification is used in the study of demyelination in neurodegenerative diseases. A novel noninvasive MRI method, Microstructure-Informed Myelin Mapping (MIMM), is proposed to quantify the myelin volume fraction (MVF) from a routine multi-gradient echo sequence (mGRE) using a multiscale biophysical signal model of the effects of microstructural myelin and iron.

Theory And Methods: In MIMM, the effects of myelin are modeled based on the Hollow Cylinder Fiber Model accounting for anisotropy, while iron is considered as an isotropic paramagnetic point source.

Correlation Between Intraoperative Near-infrared Spectroscopy Values and Neurologic Outcomes in Patients Undergoing Total Aortic Arch Replacement Using the Frozen Elephant Trunk Technique.

Objective: To correlate intraoperative near-infrared spectroscopy (NIRS) values with neurologic outcomes in patients undergoing total aortic arch replacement using the frozen elephant trunk (FET) technique.

Design: Retrospective, single-center registry study using a two-way repeated-measures analysis of variance.

Setting: Between November 2013 and December 2023, 427 patients were treated for acute and chronic aortic pathologies using the FET procedure.
