OBJECTIVE: As elastin fibres in the aorta deteriorate with age, the descending thoracic aorta (DTA) becomes longer and more tortuous. In patients with DTA aneurysms, this increased tortuosity may result in a hostile haemodynamic environment for thoracic endovascular aortic repair (TEVAR). The objective of this study was to analyse how increased tortuosity affects haemodynamic displacement forces (DFs) in different segments of the DTA in patients with DTA aneurysms (DTAAs). METHODS: Thirty patients with DTAAs were selected to form three equal groups based on the maximum tortuosity of their DTA: low < 30°, moderate 30°-60°, and high > 60°...

OBJECTIVE: To discern the impact of depressed left ventricular ejection fraction (LVEF) on the outcomes of open descending thoracic aneurysm (DTA) and thoracoabdominal aneurysms (TAAA) repair. METHODS: Restricted cubic spline analysis was used to identify a threshold of LVEF, which corresponded to an increase in operative mortality and major adverse events (MAE: operative death, myocardial infarction, stroke, spinal cord injury, need for tracheostomy or dialysis)...

OBJECTIVE: Tortuosity in the descending thoracic aorta (DTA) comes with aging and increases the risk of endoleaks after TEVAR. With this report, we would like to define and classify tortuosity in the DTA of patients with thoracic aortic disease. METHODS: Retrospective case-control study of two hundred seven patients, comparing sixty-nine controls without aortic disease (CG), to sixty-nine patients with descending thoracic aortic aneurysm (AG) and sixty-nine patients with type B aortic dissection (DG)...

BACKGROUND AND PURPOSE: Despite significant technical advances, recanalization rates after endovascular therapy of ruptured intracranial aneurysms (IAs) remain a clinical challenge. A histopathological hallmark of ruptured human IA walls is mural cell loss. Mural smooth muscle cells (SMCs) are known to promote intraluminal healing in thrombosed experimental aneurysms. In this rat model we assess the natural history and healing process after coil embolization in SMC-rich and decellularized aneurysms...

A 77-year-old woman presented with symptomatic thoracic aortic aneurysm within a dissected thoracoabdominal aorta distal to a previous Dacron ascending aortic replacement. She was not a candidate for open repair and had no proximal landing zone for conventional thoracic endovascular aortic repair (TEVAR) resulting from dissection extension into the brachiocephalic vessels. A concomitant parallel graft true and false lumen TEVAR was performed from the distal aortic arch to diaphragm. Follow-up imaging demonstrated successful exclusion of the false lumen aneurysm and successful protection of the true lumen with the adjacent parallel TEVAR device...

We report a case of a hybrid surgical treatment of a 71-year-old fragile female with severe chronic obstructive pulmonary disease with a 5-year history of progressive back pain and diagnosis of descending thoracic aorta aneurysm (DTAA), but refused operation at first. Since the patient presented with an acute expanding painful pulsatile mass due to a ruptured DTAA contained by the subcutaneous tissue and had a high-risk surgical profile, we agreed that the simplest urgent operation should be performed. Cardiopulmonary bypass with or without deep hypothermic circulatory arrest was ruled out as an option...

Described herein is a clinical case report regarding treatment of a 70-year-old male patient presenting with a late complication following endoprosthetic repair for a Stanford type B dissecting thoracic aortic aneurysm. The man was admitted to our hospital for persistent type IIb endoleak and an increased diameter of the aorta in its thoracic and thoracoabdominal portions. Two years previously, he had endured endoprosthetic repair of the thoracic aorta. The findings of computed tomography revealed negative dynamics manifesting as an increase in the diameter of the false channel of the arch and descending thoracic aorta with persistent type IIb endoleak...

A 79-year-old man presented with an enlarging thoracic aneurysm on the background of superficial bladder cancer treated with intravesical bacillus Calmette-Guérin (BCG) injections. Following the injections, he developed deranged liver function tests and hepatomegaly. Liver biopsy revealed granulomatous hepatitis compatible with disseminated mycobacterial infection (BCG-osis) and was treated with anti-tuberculosis agents for 12 months. A surveillance CT scan performed as a follow-up for his bladder cancer in 2018 revealed a saccular thoracic aneurysm at the ligamentum arteriosum, which was metabolically active on positron emission tomography (PET) scan...

BACKGROUND: TEVAR remains an important minimally invasive tool for the treatment of descending thoracic aneurysm. The long term effects of these repairs in both reduction of the aneurysmal sac size as well as stability of the stented portion require study. We report the results of 12 years of radiographic follow-up. METHODS: All patients with TEVAR for descending thoracic aneurysms from January 2005 to December 2017(n=371) were evaluated for immediate postoperative and follow-up CT scans suitable for 3D reconstruction of the aorta(excluding those with an interim reoperation)...

OBJECTIVES: Although the advent of thoracic endovascular aortic repair (TEVAR) has provided an alternative treatment option for descending thoracic aortic aneurysm (DTAA), open repair still plays a crucial role in DTAA repair. The purpose of this study was to re-evaluate the operative and long-term outcomes of open repair with partial cardiopulmonary bypass, compared to the results of TEVAR with a proximal landing zone of 3 or 4. METHODS: Between 2007 and 2017, open repair was performed for 44 patients and TEVAR for 282 patients...

We report a case of a type B aortic dissection with an aneurysm treated by the replacement of the proximal descending thoracic aorta via the reversed elephant trunk technique. A 48-year-old asymptomatic man was diagnosed with a type B aortic dissection, moderate aortic regurgitation, and a good biventricular function in March 2012. Four years later (April 2016), a contrast-enhanced computed tomography examination revealed an aneurysmal dilatation in the patient's descending thoracic aorta with a thrombosis in the proximal part of the false lumen, which warranted surgical repair...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) has expanded access to descending thoracic aortic aneurysm (DTAA) repair particularly for elderly and frail patients. This high-risk population has limited long-term overall survival, such that appropriate patient selection is required to optimize patient benefit and resource utilization. Our objective was to develop and validate a frailty based, procedure specific risk score for patients undergoing elective TEVAR for DTAA. METHODS: Patients undergoing non-emergent TEVAR for DTAA during 2005 - 2016 were identified in the National Surgical Quality Improvement Program database...

Spontaneous rupture of the thoracic aorta is a rare disease with a poor prognosis without obvious trauma, aortic aneurysm and aortic dissection. We report 2 cases of successful endovascular aortic repair for spontaneous rupture of the thoracic aorta. Case 1:A 79-year-old man was referred to our hospital complaining of general fatigue. He returned home without any obvious abnormalities in blood tests and computed tomography (CT). The patient was aware of dizziness and fluttering in the early morning the next day, and was transported to the hospital by shock vital...

An 88-year-old man was admitted with general fatigue. Computed tomography (CT) showed a descending aortic aneurysm. The laboratory data indicated severe infection. Despite negative blood cultures, broad-spectrum intravenous antibiotic therapy was started. Though antibiotic therapy was continued for about 2 weeks, the aneurysm extended 20 mm. Thoracic endovascular aortic repair was performed, and antibiotic therapy was continued for 4 weeks after the procedure, followed by oral antibiotics for 1 year. CT showed regression of the aneurysm 15 months after reconstruction...

BACKGROUND: Aortic dissection is a separation of the aortic wall, caused by blood flowing through a tear in the inner layer of the aorta. Aortic dissection is an infrequent but life-threatening condition. The incidence of aortic dissection is 3 to 6 per 10,000 per year in the Western population, and can be up to 43 per 10,000 per year in the Eastern population. Over 20% of people with an aortic dissection do not reach a hospital alive. After admission, the mortality rates for people with an aortic dissection are between 10% and 20% for those who received endovascular treatment, and between 20% and 30% for those who had open surgery...
