The impact of circulatory arrest with selective antegrade cerebral perfusion on brain functional connectivity and postoperative cognitive function.

Aortic surgery is one of the most challenging types of surgeries, which is possibly related to cognitive sequelae. We aimed to investigate the changes in resting-state functional connectivity (rsFC) associated with intraoperative circulatory arrest (CA) in aortic surgery, exploring the relationship between the altered connectivity and postoperative cognitive functions. Thirty-eight patients participated in this study (14 with CA, 24 without).

Mid-term outcomes of hybrid debranching endovascular aortic arch repair in landing zones 0-2.

Objectives: The aim of this study is to summarize a single-center experience of hybrid debranching endovascular repair of the aortic arch and proximal descending thoracic aorta (DTA) with regard to the mid-term outcomes with highlighting the difference between the landing zones 0-2.

Methods: A retrospective review of data from a prospectively collected registry (Gangnam Severance Endovascular Aortic Registry) was performed. From among 332 patients whose aortic pathology was managed with TEVAR, 112 patients who underwent hybrid arch repair during the study period between 2012 and 2016 were identified.

Note the descending aorta: predictors of postoperative major adverse aortic event in pure acute type A intramural hematoma.

Background: Intramural hematomas (IMHs) may originate from small intimal tears. Although most surgeries for acute type A IMH are conventionally performed solely at the proximal aorta, regardless of the primary intimal tear site, the remnant aortic remodeling stays important during the follow-up period after surgery.

Methods: Forty-seven patients with "pure" acute type A IMHs who underwent surgery from January 2008 to December 2019 were retrospectively analyzed.
