A Case of Acute Aortic Dissection in an Older Patient of Advanced Age.
Cureus
November 2024
Cardiovascular Surgery, Sapporo Medical University, Sapporo, JPN.
The patient an 85-year-old female resided in a care facility where she maintained an independent daily activity level. She was discovered hunched over a table in her room, displaying reduced responsiveness and prompting an emergency call. Initially, her blood pressure was within 60 mmHg, and she was transported by ambulance to our hospital.

Article Synopsis
- Selective antegrade cerebral perfusion (SACP) is a technique used to maintain brain blood flow during aortic arch surgeries that require temporary stopping of blood circulation, with two methods: bilateral (bSACP) and unilateral (uSACP), each having its risks.
- A new predictive method was developed and tested to determine cerebral perfusion pressures (CPP) during SACP, helping surgeons decide which SACP approach to use preoperatively, utilizing patient-specific imaging and simulations.
- The study involved five patients and demonstrated that the prediction method was accurate, with minimal errors in CPP predictions, highlighting the importance of collateral artery size for accurate modeling in surgical planning.
Application of Bilateral Cerebral Perfusion + Balloon Occlusion of Descending Aorta + Antegrade Perfusion of Lower Body in Debakey Type I Aortic Dissection.

Department of Thoracic and Cardiovascular Surgery, Changsha Hospital of Traditional Chinese Medicine (Changsha Eighth Hospital), Changsha, Hunan, China.
Article Synopsis
- The study aimed to evaluate a new perfusion method in surgery for DeBakey Type I aortic dissection, focusing on improving organ protection and patient outcomes.
- Thirty-two patients underwent surgery using a combination of perfusion techniques, and outcomes showed no significant complications like paraplegia, with a low mortality rate of 3.13%.
- The results suggest that the new perfusion method effectively protected lower-body organs during surgery, but further research is needed to assess long-term benefits.
Optimal circulatory arrest temperature for total aortic arch replacement: outcomes of neurological complications.

Background: The optimal hypothermic circulatory arrest (HCA) temperature during total arch replacement (TAR) and the impact of HCA temperature on postoperative neurological complications are still uncertain.
Objective: The aim of this study is to explore the impact of HCA temperature on short-term postoperative outcomes, especially neurological complications, for patients who undergo TAR.
Methods: We retrospectively analyzed data of 2351 patients who underwent TAR at one of seven selected aortic centers from January 2016 to June 2023.
Contemporary Single-Center Experience of Complete Aortic Arch Replacement Employing the Frozen Elephant Trunk Technique in Patients with Extensive Aortic Disease.
J Clin Med

Department of Cardiothoracic and Vascular Surgery, Kepler University Hospital, Medical Faculty, Johannes Kepler University Linz, 4020 Linz, Austria.
This study aimed to examine contemporary results of the frozen elephant trunk (FET) procedure in an all-comers patient cohort. Between January 2017 and May 2024, a total of 132 consecutive patients with either aortic aneurysm ( = 32), acute aortic dissection ( = 32), or chronic aortic dissection ( = 68) underwent total aortic arch replacement employing the FET technique. In-hospital data were collected prospectively and included preoperative characteristics, intraoperative data, and follow-up results.
