Non-infectious aortitis is usually due to giant-cell arteritis, Takayasu disease or Behçet disease. The main aortic lesions are stenoses, occlusions and aneurysms in the Takayasu disease and aneurysms in the Behçet disease and giant-cell arteritis. Treatment is based on corticosteroid therapy and surgery. Endoluminal management is now the rule. We report a retrospective descriptive study of 10 patients who underwent surgical or endoluminal management of inflammatory lesions of the aorta between January 2000 and December 2015...

Autophagy is upregulated in spinal cord ischemia reperfusion (SCIR) injury; however, its expression mechanism is largely unknown; moreover, whether autophagy plays a neuroprotective or neurodegenerative role in SCIR injury remains controversial. To explore these issues, we created an SCIR injury rat model via aortic arch occlusion. Compared with normal controls, autophagic cell death was upregulated in neurons after SCIR injury. We found that autophagy promoted neuronal cell death during SCIR, shown by a significant number of terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling- (TUNEL-) positive cells colabeled with the autophagy marker microtubule-associated protein 1 light chain 3, while the autophagy inhibitor 3-methyladenine reduced the number of TUNEL-positive cells and restored neurological and motor function...

Abdominal aortic pathology is a diverse topic, ranging through a broad span of possible pathologies. The treatment options are equally vast, particularly with the ever-expanding endovascular techniques. In this article, we discuss management strategies for abdominal aortic aneurysms and aortic occlusive disease, because they represent some of the most common pathologies encountered in clinical scenarios.

Background The endovascular approach has become a mainstay in the treatment of aortic aneurysms. While the transfemoral approach is most commonly used, it is often inaccessible due to a vascular pathology, such as occlusion, tortuosity or heavy calcifications. The transapical access provides an alternative approach. The goal of this study is to report the feasibility of the transapical approach for total endovascular repair of thoracic aortic aneurysms (TEVAR). Methods Three patients with thoracic aortic aneurysms with inaccessible femoral arteries underwent TEVAR via the transapical approach...

Aortic regurgitation (AR) is a life-threatening complication of Takayasu arteritis (TA). Takayasu arteritis is a large-vessel vasculitis with a predominance in young adolescent and adult females. Inflammation involves the aorta and its major branches resulting in arterial dilatation, stenosis, aneurysm, occlusion, and thrombosis formation. Pediatric TA cases have been reported to also cause severe complications such as coronary aneurysms, retinopathy, and hypertension due to renovascular stenosis. In this report, we present a rare occurrence of infantile TA with severe AR requiring surgical intervention after failing medical therapy...

Congenital aortic atresia is a malformation accounting for 4 - 6% of all congenital heart diseases in children. Left ventricular outflow obstruction due to atresia is common at the aortic valve but rarely has atresia been identified in the descending aorta. We report the case of a 25-year woman who was evaluated for headache and uncontrolled hypertension. CTscan chest showed a short atretic segment in the descending aorta at the isthmus, distal to the takeoff of the subclavian artery. She underwent surgery; a 22 mm Dacron graft was taken and jump graft was placed between the arch of the aorta and the descending aorta, using partial occlusion clamps...

The most common genetic alterations for familial thoracic aortic aneurysms and dissections (TAAD) are missense mutations in vascular smooth muscle (SM) α-actin encoded by ACTA2 We focus here on ACTA2-R258C, a recurrent mutation associated with early onset of TAAD and occlusive moyamoya-like cerebrovascular disease. Recent biochemical results with SM α-actin-R258C predicted that this variant will compromise multiple actin-dependent functions in intact cells and tissues, but a model system to measure R258C-induced effects was lacking...
