Article Synopsis
- Researchers have explored a novel enzyme, LrN1 GtfB, from the GtfB subfamily that modifies pea starch by creating new types of linkages.
- The enzyme increases the amount of specific (α1 → 6) linkages and reduces the molecular weight of the starch, resulting in shorter, low-molecular-weight molecules.
- The modified pea starch exhibits weaker structural properties and lower retrogradation, suggesting valuable applications in creating starch-based products with unique characteristics.
Clinical efficacy of TEVAR utilizing fenestrated stent-grafts for zone 0 in an elderly frail patient with giant aortic arch aneurysm.
Ann Med Surg (Lond)
August 2024
Department of Cardiovascular & Thoracic Surgery, Graduate School of Medicine, EHIME University, Toon.
Introduction And Importance: Elderly and frail patients with thoracic aortic aneurysms (TAAs) near to origins of cervical arteries present facing challenges with aortic arch replacement with cardiopulmonary bypass, and traditional tube-type stent-grafts are also inadequate for transcatheter endovascular aortic repair (TEVAR). Thus, necessitating precise treatment with fenestrated stent-grafts from zone 0. This approach is crucial for achieving favorable postoperative outcomes without compromising activities of daily living (ADL).

Objective: This study aimed to analyze early and midterm results of custom-made proximal scallop and fenestrated stent grafts for thoracic endovascular aortic repair (TEVAR) with a proximal landing zone (PLZ) in the aortic arch.
Methods: All consecutive patients treated with the custom made proximal scalloped and fenestrated Relay stent grafts (Terumo Aortic Bolton Medical Inc.) in 10 Italian centers between January 2014 and December 2022 were included.
Hybrid Management of Dysphagia Lusoria with Tevar Implantation and Bilateral Subclavian Arteries Debranching: A Review of the Literature and a Case Report.

Aberrant right subclavian artery (ARSA) causing dysphagia, the so-called "dysphagia lusoria", is a frequent embryologic anomaly of the aortic arch. In symptomatic patients, studies report several management options including surgical, hybrid, and totally endovascular strategies. Hybrid techniques have the advantage of no chest opening with reduced morbidity, but the problem of the ARSA stump causing recurrent or persistent dysphagia remains challenging in some cases.
