Background: This case report details familial aortic dissection in 2 second-degree blood relatives who experienced sudden aortic dissections. One patient underwent emergency computed tomography angiography (CTA) and the other underwent magnetic resonance angiography (MRA). These imaging examinations were instrumental in revealing each patient's condition. One patient died of dissection rupture while being prepped for surgery. The other patient underwent surgery, recovered, and undergoes continual monitoring for the condition.
Discussion: A positive family history of aortic dissection should be considered in patients presenting with aortic emergencies. Many genes can contribute to this condition, with most genes relating to smooth muscle and connective tissue disorders. Imaging studies for evaluating and monitoring aortic dissection include transesophageal echocardiography, CTA, and MRA. Surgical treatment is possible for aortic dissection, with the goals being to stabilize the dissection and reduce the possibility of rupture.
Conclusion: The mortality rate for aortic dissection is high, with the main cause of death being dissection rupture. Lifelong monitoring of survivors and first-degree relatives is recommended.

Thoracic and abdominal aortic aneurysm poses a substantial mortality risk in adults, yet many of its underlying factors remain unidentified. Here, we identify mitochondrial nicotinamide adenine dinucleotide (NAD)⁺ deficiency as a causal factor for the development of aortic aneurysm. Multiomics analysis of 150 surgical aortic specimens indicated impaired NAD salvage and mitochondrial transport in human thoracic aortic aneurysm, with expression of the NAD transporter SLC25A51 inversely correlating with disease severity and postoperative progression.

Type B aortic dissection (TBAD) primarily affects men aged 60-65, with hypertension in over 80% of cases. The gold standard for the treatment of uncomplicated acute TBAD is Best Medical Therapy (BMT), which focused on controlling blood pressure and heart rate. However, Thoracic Endovascular Aortic Repair (TEVAR) has gained attention over the years, especially for complicated TBAD cases, by covering the primary entry tear, lowering false lumen pressure, and promoting aortic remodeling.

Ulinastatin is a protease-inhibiting drug with anti-inflammatory and other pharmacological properties. Little is known regarding its role following acute type A aortic dissection (ATAAD) surgery. We perform a randomized controlled trial to investigate the protective effect of ulinastatin against negative inflammatory response and organ dysfunction in ATAAD surgery (PANDA).

Background: Extensive surgical resection of the thoracic aorta in patients with type A aortic dissection (TAAD) is thought to reduce the risk of late aortic wall degeneration and the need for repeat aortic operations.
Objectives: We evaluated the early and late outcomes after aortic root replacement and supracoronary ascending aortic replacement in patients with TAAD involving the aortic root.
Design: Retrospective, multicenter cohort study.

Infectious aortitis is an uncommon but potentially fatal condition that can lead to aortic dissection or rupture. We describe a case of a 69-year-old female who developed a Stanford type B aortic dissection, presumptively caused by Salmonella, which was successfully managed with thoracic endovascular aneurysm repair (TEVAR) and long-term antibiotics. A literature review of 17 reported cases from 2000 to 2024 of aortic dissection secondary to infectious aortitis was conducted.
