OBJECTIVE: To assess prevalence of aortic involvement in relapsing polychondritis (RP) patients; to evaluate clinical features and long-term outcome of RP patients exhibiting aortitis, aortic ectasia and/or aneurysm. METHODS: 172 RP patients underwent aortic computed tomography (CT)-scan; they were seen in 3 medical centers. RESULTS: 11 patients (6.4%) had aortic involvement, occurring within a median time of 2 years after RP diagnosis. CT-scan showed isolated aortitis (n=2); the 9 other patients exhibited: aortitis and aortic aneurysm (n=2) or ectasia (n=1), isolated aortic aneurysm (n=4) or ectasia (n=2); aortic localizations were as follows: thoracic (n=6), abdominal (n=2), thoracic and abdominal (n=4) aorta...

Spinal cord injury remains a major adverse event of extended thoracic and thoracoabdominal aortic surgical procedures. Preoperative identification of the Adamkiewicz artery and prompt reattachment of the targeted intercostal arteries during operation should contribute to preventing spinal cord injury. In this report, we describe a simple and definite identification of the critical intercostal artery during extended descending and thoracoabdominal aortic surgical procedures.

We describe a case of total arch replacement with frozen elephant trunk for chronic type B aortic dissecting aneurysm, which resulted in inadvertent landing of the frozen elephant trunk into the false lumen. A radiofrequency puncture system-assisted controlled endovascular fenestration of the dissection flap was performed at the upper abdominal aorta and subsequent thoracic endovascular stenting, successfully redirecting the blood flow from the false to the true lumen. Our case illustrated a possible way to seal distal reentry in chronic type B aortic dissection...

BACKGROUND: Ascending thoracic aortic aneurysm (aTAA) is a heterogeneous group of disorders that involve impaired endothelial function. The nitric oxide (NO) synthase inhibitor asymmetric dimethylarginine (ADMA) serves as an endothelial dysfunction marker. Thus, we investigated ADMA levels in patients with aTAA. METHODS: Eighty-six patients with aTAA and 18 healthy individuals were enrolled. All patients underwent echocardiography. Plasma ADMA levels were measured using high-performance liquid chromatography...

An 83-year-old male with multiple comorbidities presented with critical aortic stenosis and a saccular aortic arch aneurysm. Through a mini thoracotomy, a balloon expandable transcatheter aortic valve was delivered transapically. A thoracic stent graft was then delivered through the prosthetic valve and deployed in the arch, while a covered stent was deployed in the left common carotid artery. Three-year postoperative computed tomography showed a thrombosed arch aneurysm with decreased size. This case demonstrates the feasibility of using combined transapical transcatheter technologies to treat multicomponent disease in a high-risk patient during a single operation...

IgG4 related thoracic aortitis is a recent addition to the differential diagnosis for inflammatory aortic disease - a condition which is often underappreciated until complications arise such as aneurysmal formation or aortic dissection. Currently, IgG4 aortitis remains a post-surgical diagnosis reliant on positive immunohistochemistry findings. Management is guided by the extent of disease involvement, which can be gauged by serum IgG4 levels and radiological findings. Options include surgical resection, corticosteroid therapy and steroid-sparing agents to prevent relapses...

We report the case of a patient who developed paraparesis 2 days after endovascular aneurysm repair for a right common iliac aneurysm. The patient had undergone thoracic endovascular aortic repair. The left subclavian artery was occluded, but the left internal iliac artery was preserved. The patient fully recovered from the paralysis within 3 months. This case illustrates the importance of collateral blood supply to the spinal cord from the lumbosacral region, especially when other sources are occluded.

A 72-year-old man presented with aneurysms of the distal aortic arch and the distal descending aorta due to chronic type B aortic dissection. We first performed thoracic endovascular aortic repair (TEVAR) in the distal descending aorta, and the aneurysm was successfully excluded using a Gore Tag stentgraft. Seven days after TEVAR, computed tomography revealed retrograde type A aortic dissection occurring from the ascending aorta to the distal aortic arch. In emergency surgery, ascending aorta and total arch replacement were performed under selective cerebral perfusion with moderate hypothermia, and after coming off cardiopulmonary bypass, the distal aortic arch aneurysm was excluded using a Gore Tag stentgraft...

A 14-year-old dog weighing 4 kg presented with hypotension only in the right forelimb. Thoracic radiography revealed a round soft tissue opacity near the aortic arch and below the second thoracic vertebra on a lateral view. Three-dimensional computed tomography angiography clearly revealed stenosis and aneurysmal dilation of an aberrant right subclavian artery. Stenosis and aneurysm of an aberrant subclavian artery should be included as a differential diagnosis in dogs showing a round soft tissue opacity near the aortic arch and below the thoracic vertebra on the lateral thoracic radiograph...

OBJECTIVES: The aberrant right subclavian artery or arteria lusoria (AL) is the most frequent anatomical variation of the supra-aortic trunks (SAT). Treatment is only warranted in presence of an aneurysm because of the risk of rupture or in symptomatic cases with signs of compression of the esophagus or the trachea, with embolisms causing right upper limb ischemia of vertebrobasilar cerebrovascular accidents (CVA). The conventional surgical treatment of AL is the closure of the origin of AL and the revascularization of the artery right subclavian through a left thoracotomy...

Thoracic aortic aneurysms are life-threatening lesions that afflict young and old individuals alike. They frequently associate with genetic mutations and are characterized by reduced elastic fibre integrity, dysfunctional smooth muscle cells, improperly remodelled collagen and pooled mucoid material. There is a pressing need to understand better the compromised structural integrity of the aorta that results from these genetic mutations and renders the wall vulnerable to dilatation, dissection or rupture. In this paper, we compare the biaxial mechanical properties of the ascending aorta from 10 murine models: wild-type controls, acute elastase-treated, and eight models with genetic mutations affecting extracellular matrix proteins, transmembrane receptors, cytoskeletal proteins, or intracellular signalling molecules...

OBJECTIVES: Although conventional open repair is our preference for patients with aortic arch aneurysms, we have often chosen thoracic endovascular aneurysm repair (TEVAR) with a handmade branched stent graft (bTEVAR) in high-risk patients. The aim of this study was to compare the midterm clinical outcomes of our bTEVAR technique to those of the open repair. METHODS: Between January 2007 and December 2014, we treated 129 patients with aortic arch aneurysm by means of either conventional open repair (OPEN, n  = 61) or bTEVAR ( n  = 68) at our institution...

It has been suggested that matrix metalloproteinase (MMP) polymorphisms are associated with the pathogenesis of aortic aneurysmal diseases. In this study, we conducted a systematic review with an update meta-analysis to investigate the relationship between MMP family polymorphisms and aortic aneurysmal diseases. We systematically reviewed 24 polymorphisms in eight MMP genes related to the risk of abdominal aortic aneurysm (AAA), thoracic aortic aneurysm (TAA) or thoracic aortic dissection (TAD). A total of 19 case-control studies with 15 highly studied MMP polymorphisms were included in our meta-analysis...

BACKGROUND: The transposition of the great arteries (TGA) is one of the most severe congenital heart diseases. The arterial switch operation (ASO) is the preferred procedure to treat TGA. Although numerous reports have shown good results after ASOs, some patients suffer from circulatory system problems following the procedure. One reason for problems post-ASO is the local changes in the curvature and torsion of the thoracic aorta. OBJECTIVE: The influence of these geometric changes on the blood flow field needs to be investigated in detail to consider possible cardiovascular problems after an ASO...
