From december 1996 to april 1999, 25 patients with true aortic arch aneurysm underwent aortic arch aneurysm repair using selective cerebral perfusion. There were 17 males and 8 females ranging in age from 62 to 79 years (mean 71 years). Orikaesi method was used in the procedure of distal anastomosis for complete aortic arch replacement with a prosthetic graft. This technique allowed us a simple approach to the lesion and the easy additional stitch. The average duration of extracorporeal circulation, aortic crossclamping, selective cerebral perfusion were 269 minutes, 140 minutes, and 122 minutes, respectively, under 19.3 degrees C of lowest esophageal temperature. There were no cases complicated with postoperative low output syndrome and cerebrovascular accident, and no hospital mortality. Replacement of the aortic arch using selective cerebral perfusion is a safe procedure with acceptable hospital mortality.

Pregnancy-related chronic type A aortic dissection highlights the importance of thorough prenatal maternal examination.
J Cardiothorac Surg
January 2025
Semmelweis University Heart and Vascular Centre, Budapest, 1122, Hungary.
Background: Aortic dissection occurs rarely during pregnancy but carries a significantly high vital risk for both the mother and the fetus. Early diagnosis and treatment are critical for a successful outcome.
Case Presentation: A 32-year-old pregnant woman at 31 weeks of gestation began experiencing shortness of breath, chest pain, and palpitations, which were attributed to an anxiety disorder she had been previously diagnosed with.
Lobectomy Increases Postoperative Pulmonary Artery Enlargement to a Greater Extent than Segmentectomy.
Ann Thorac Cardiovasc Surg
January 2025
Division of Thoracic Surgery, Department of Surgery, Kobe University Hospital and Graduate School of Medicine, Kobe, Hyogo, Japan.
Purpose: The underlying mechanism why segmentectomy has demonstrated the non-inferiority to lobectomy in several randomized trials remains unclear. Computed tomography (CT)-measured pulmonary artery (PA) enlargement reflects PA pressure and predicts the prognosis of certain respiratory diseases. We compared the preoperative and postoperative PA diameter to the ascending aorta diameter (PA/A) ratio, investigating its impact on right ventricular function in lung resection.

Background: Vascular aging is the basis of many chronic diseases of the aged, such as hypertension, coronary heart disease and stroke.
Objective: This study aims to deepen our understanding of the pathological mechanisms of vascular aging by combining multiple big data research methods, and reveal potential therapeutic targets and biomarkers.
Methods: WGCNA method was used to integrate the aortic transcriptome data of multiple age stages, and extract the key module and key pathway.
Incorporating an Elevated Perfusion Index in the Right Hand Enhanced Screening Sensitivity for Critical Aortic Arch Obstruction in Newborn Infants.
Acta Paediatr
January 2025
Department of Pediatric Cardiology, Queen Silvia Children's Hospital at the Sahlgrenska University Hospital, Gothenburg, Sweden.
Aim: Newborn infants with critical aortic arch obstruction are often undiagnosed at discharge, despite screening. This study investigated if adding the perfusion index improved early detection.
Methods: We retrospectively studied 38 newborn infants with critical aortic arch obstruction, who were routinely screened in 2014-2019 by 13 Swedish hospitals using pulse oximetry and the perfusion index.
PP2A Attenuates Thoracic Aneurysm and Dissection in Mouse Models of Marfan Syndrome.
Hypertension
January 2025
Cardiology Division, Department of Medicine, Emory University School of Medicine, Atlanta, GA. (X.Z., Q.X., A.V., Z.L.).
Background: Recent studies show that hyperactivation of mTOR (mammalian target of rapamycin) signaling plays a causal role in the development of thoracic aortic aneurysm and dissection. Modulation of PP2A (protein phosphatase 2A) activity has been shown to be of significant therapeutic value. In light of the effects that PP2A can exert on the mTOR pathway, we hypothesized that PP2A activation by small-molecule activators of PP2A could mitigate AA progression in Marfan syndrome (MFS).
