AI Article Synopsis
- A 66-year-old man experienced chills, difficulty breathing, and palpitations, which escalated to fever; he was diagnosed with acute myocarditis based on medical tests.
- His condition worsened, requiring an intra-aortic balloon pump and later venoarterial extracorporeal membrane oxygenation due to a serious heart rhythm issue; tests revealed elevated lactate levels and an aortic thrombus.
- After identifying heparin-induced thrombocytopenia, treatment was adjusted to argatroban, and surgical intervention successfully restored blood flow, leading to the patient's stabilization and eventual discharge after 47 days.
Article Abstract
A 66-year-old man presented with chills, exertional dyspnea, and palpitations; he later developed a fever. Because of his elevated cardiac enzymes and electrocardiography and coronary angiography findings, he was diagnosed with acute myocarditis. Given his unstable hemodynamics, an intra-aortic balloon pump was inserted; however, he experienced a hemodynamic collapse due to refractory ventricular fibrillation. He was then cannulated with venoarterial extracorporeal membrane oxygenation and microaxial flow pump and underwent steroid pulse therapy. His lactate levels were elevated, and computed tomography imaging revealed an aortic thrombus possibly formed in the mixing zone of the venoarterial extracorporeal membrane oxygenation and microaxial flow pump. Based on the antibody test results, he was diagnosed with heparin-induced thrombocytopenia; thus, heparin was replaced with argatroban. Surgical intervention restored the arterial flow. The patient was stabilized and discharged on day 47.

Aortic aneurysm, the pathological dilatation of the aorta at distinct locations, can be attributed to many different genetic and environmental factors. The resulting pathobiological disturbances generate a complex interplay of processes affecting cells and extracellular molecules of the tunica interna, media and externa. In short, aortic aneurysm can affect processes involving the extracellular matrix, lipid trafficking/atherosclerosis, vascular smooth muscle cells, inflammation, platelets and intraluminal thrombus formation, as well as various endothelial functions.

Objective: To develop an unsupervised artificial intelligence algorithm for identifying and quantifying the presence of false lumen thrombosis (FL) after Frozen Elephant Trunk (FET) operation in computed tomography angiographic (CTA) images in an interdisciplinary approach.
Methods: CTA datasets were retrospectively collected from eight patients after FET operation for aortic dissection from a single center. Of those, five patients had a residual aortic dissection with partial false lumen thrombosis, and three patients had no false lumen or thrombosis.
Endovascular treatment of postoperative aortic coarctation aneurysms-a single center experience.

Background: Formation of local type aortic aneurysm years after surgical repair of coarctation (CoA) occurs in 10% of patients independent of the surgical technique and is a potentially life-threatening condition if left untreated with a high risk of aortic rupture. Redo open surgery is associated with 14% in-hospital mortality and a high risk of complications. Endovascular treatment appears to be a feasible alternative with a high success rate and low morbidity and mortality, but data concerning long-term results is still mandatory.

Traditional mouse models for deep vein thrombosis (DVT), frequently utilized in research focused on cancer-associated thrombosis (CAT), reliably induce thrombus formation by obstructing blood flow (BF) in the inferior vena cava (IVC), which does not occur in humans. Therefore, to develop a new DVT model for CAT studies, we implanted an ameroid constrictor (AC), a hygroscopic casein C-shape device, around the IVC and aorta of immunocompromised mice. We evaluated the thrombus 3 and 8 days post-AC implantation and compared it with the traditional model 2 days post-vena cava ligation.

Article Synopsis
- The study evaluates the safety and effectiveness of the Zenith Dissection Endovascular System (ZDES) against traditional stent grafts for repairing acute complicated Type B Aortic Dissection (AcTBAD).
- A retrospective analysis of 32 patients revealed that the ZDES group experienced fewer postoperative adverse events (12 vs. 37), demonstrating better outcomes in false lumen thrombosis at 6 months and lower 3-year mortality rates.
- Despite some patients needing secondary interventions in the ZDES cohort due to aortic growth, overall results suggest the ZDES may offer improved safety and efficacy compared to traditional methods.
