We present the case of a 74-year-old female patient with a 50 mm ascending aortic aneurysm who underwent ascending aorta replacement. During routine open heart surgery, suboptimal flow in the cardiopulmonary bypass circuit, led to the discovery of a type B aortic dissection with substantial flow in the false lumen. Conservative management was chosen, focusing on blood pressure control in the ICU. Despite an initial uneventful recovery the patient developed malperfusion syndrome prompting consideration of endovascular repair. Following a temporary improvement, malperfusion symptoms recurred, leading to a successful endovascular repair, with complete thrombosis of the false lumen.

Background: Thoracic aortic pathologies involving the aortic arch are a great challenge for vascular surgeons. Maintaining the patency of supra-aortic branches while excluding the aortic lesion remains difficult. Thoracic EndoVascular Aortic Repair (TEVAR) with fenestrations provides a feasible and effective approach for this type of disease.

Objectives: Celiac artery (CA) incorporation during FB-EVAR for complex abdominal aortic aneurysms (cAAA) is typically performed with fenestrations. Double-wide scallops (DWS) can be used when appropriate. We aimed to assess outcomes of patients treated with DWS for the CA during FB-EVAR for cAAA.

Objective: Cloud-based, surgical augmented intelligence (Cydar Medical, Cambridge, UK) can be used for surgical planning and intraoperative imaging guidance during complex endovascular aortic procedures. We aim to evaluate radiation exposure, operative safety metrics, and post-operative renal outcomes following implementation of Cydar imaging guidance using a manually matched cohort of aortic procedures.
Methods: We retrospectively reviewed our prospectively maintained database of endovascular aortic cases.

Background And Aim: Our previous research indicates that sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2) dysfunction facilitates the phenotypic transformation of aortic smooth muscle cells (ASMCs) and intensifies aortic aneurysm through the regulation of calcium-dependent pathways and endoplasmic reticulum stress. Our hypothesis is that additional mechanisms are involved in aortic aneurysm and atherosclerosis induced by SERCA2 dysfunction from the perspective of ASMC phenotypic transformation.
Methods & Results: In SERCA2 dysfunctional mice and their control littermates, ASMCs were isolated to analyze protein expression and cell functions, and angiotensin II was infused into these mice that were backcrossed into LDL receptor deficient background to induce aortic aneurysm and atherosclerosis.

In general, ghrelin is known as one of the orexigenic hormones in mammals. On the other hand, it has been shown that ghrelin inhibits water intake, which appear to be inconsistent with its role in the feeding response. In this study, the effect of ghrelin on water intake was comprehensively addressed using conscious seawater-acclimated eels known as an experimental model for water drinking behaviour.
