Perioperative dynamic changes of systemic inflammatory response, gut injury, and hypoxemia in patients with acute type-A aortic dissection: an observational case-control study.

Background: The details regarding the pathogenesis of hypoxemia in the presence of acute type-A aortic dissection (ATAAD) remains to be fully elucidated. In this study, we investigated the dynamic changes in systemic inflammatory response, gut injury, hypoxemia, and succinate levels in patients with ATAAD and their impact on perioperative hypoxemia.
Methods: We conducted a single-center, observational, case-control study that enrolled 18 patients with ATAAD who underwent emergency total arch repair (TAR) combined with frozen elephant trunk (FET) procedure under hypothermic lower-body circulatory arrest and antegrade cerebral perfusion.
Aneurysmal size reduction in the Kommerell diverticulum by stent graft-based therapy.

Kommerell diverticulum (KD) with an aberrant subclavian artery is a rare congenital anomaly that often resembles a saccular aneurysm. Open surgery is the traditional treatment; however, recent reports have suggested success with endovascular or hybrid approaches. This study aimed to show the results of stent graft-based treatment and demonstrate the aneurysmal reduction rate in KD.

Trunk-like robots have attracted a lot of attention in the community of researchers interested in the general field of bio-inspired soft robotics, because trunk-like soft arms may offer high dexterity and adaptability very similar to elephants and potentially quite superior to traditional articulated manipulators. In view of the practical applications, the integration of a soft hydrostatic segment with a hard-articulated segment, i.e.

Background: Acute type A aortic dissection (ATAAD) requires emergency surgery, but the choice of primary surgery remains controversial. It is believed that simple ascending aorta replacement may lead to higher postoperative survival rate, while the Sun procedure [frozen elephant trunk (FET) + total arch replacement (TAR)] performed in the first stage may obtain better long-term results. The study aimed to compare the outcome of ATAAD patients who underwent the Sun procedure with those without TAR + FET.

Background: Stroke is one of the severe complications following surgery in patients with acute type A aortic dissection (ATAAD). This study investigates the relationship between the preoperative serum uric acid to serum creatinine ratio (SUA/Scr) and postoperative stroke in patients undergoing total arch replacement with elephant trunk implantation for aortic dissection.
Methods: We included ATAAD patients who were hospitalized and underwent surgery between June 1, 2015 and June 1, 2023, with complete clinical information.
