OBJECTIVE: Reported are initial 12-month outcomes of patients with chronic symptomatic aortic dissection managed by the Streamliner Multilayer Flow Modulator (SMFM; Cardiatis, Isnes, Belgium). Primary end points were freedom from rupture- and aortic-related death, and reduction in false lumen index. Secondary end points were patency of great vessels and visceral branches, and freedom of stroke, paraplegia, and renal failure. METHODS: Out of 876 SMFM implanted globally, we have knowledge of 542...

BACKGROUND: Severe aortic tortuosity of the access route often prevents successful complete exclusion of an aneurysm in thoracic endovascular aortic repair (TEVAR). CASE PRESENTATION: We performed antegrade TEVAR on a 79-year-old man with right hemiparesis. We deployed the stent graft from the ascending aorta with a tube graft conduit to treat a descending thoracic aortic aneurysm associated with rickets and multiple comorbidities. Although the application of a ministernotomy diminished the potential advantages of endovascular treatment in view of less invasive surgery, antegrade TEVAR using an ascending aortofemoral through-and-through wire technique was a good option in this patient because a conventional retrograde approach was not feasible due to his severely tortuous aorta...

OBJECTIVES: To analyse the results and review the literature about thoracic aortic endovascular repair (TEVAR) for type B acute aortic dissection (TBAAD) complicated by descending thoracic aortic aneurysm (DTA) in the hyperacute or acute phases. METHODS: This was a multicentre, observational descriptive study. Inclusion criteria were TBAAD with a DTA of ≥50 mm, TBAAD on an already known aneurysmal descending thoracic aorta, and TBAAD presenting with an enlarged aorta with a total diameter <50 mm, but with >50% diameter increase compared with a previous computed tomography angiography (CTA) showing a non-dissected aorta with normal sizing...

BACKGROUND: Ascending and thoracic aortic dissections progress into thoracoabdominal aneurysms 20-40% of the time, due to the initial aortic injury with associated weakness of the aortic wall. The increased firmness of the intimal flap usually results in a collapsed true lumen that does not spontaneously re-expand even with progressive dilatation of the aorta. In an effort to identify a safe and effective treatment path for this complex disease process, we present 4 cases illustrating successful sequential thoracic endovascular aortic repair (TEVAR) and fenestrated endovascular aortic repair (FEVAR)...

OBJECTIVES: Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. METHODS: During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included...

QUESTIONS UNDER STUDY: This pilot study aimed to assess the feasibility, acceptance and costs of an ultrasound scan screening programme for abdominal aortic aneurysms (AAA) in the elderly male population resident in Canton Ticino, Switzerland. METHODS: The target population were male patients aged 65-80 years who attended the outpatient clinics of the Lugano Regional Hospital in 2013. The patients showing interest were contacted by phone to verify their eligibility and fix the appointment for the ultrasound scan of the abdominal aorta...

We describe the case of a 23-year-old white female, 10-12 weeks pregnant, with a history of intravenous drug use and a recently diagnosed pneumonia, who was found deceased in her bed after a night of sleep. Although postmortem serum toxicology tested positive for alprazolam, tetrahydrocannabinol, and morphine, the ultimate cause of death was determined to be cardiac tamponade secondary to an isolated abscess in the ascending aorta. The patient had several risk factors for aortic rupture and cardiac tamponade including intravenous drug use, pneumonia, and pregnancy...

Abdominal aortic aneurysm (AAA) is the progressive dilation of the abdominal aorta. Nicotine is reported to be associated with the development and rupture of AAA, but the pathological effects of nicotine on normal rat aorta have not been determined. We investigated pathological changes in the aortic wall of rats caused by the administration of nicotine. Nicotine administration weakened the vascular wall, increased gelatinolytic activity and promoted the destruction of elastin and collagen in the rat abdominal aorta...

The first successfully diagnosed and treated case of aorta-right atrial tunnel was reported by Coto et al. in 1980. The most common cause of aorta-right atrial tunnel is a ruptured aneurysm of the sinus of Valsalva. Sinus of Valsalva aneurysms had been reported as early as 1840 by Thurnam; these were diagnosed at autopsy. With the advances in radiology, many cases of aorta-right atrial tunnel have been reported since then, each with its own subtle variations. We report on a unique case of aorta-right atrial tunnel with a windsock aneurysm in the right atrium...

Aortic dissection is a life threatening cardiovascular catastrophy. Its incidence estimated to 5-6 cases per 100,000 patients/year. The intimal tear happens at the ascending aorta in Type A, meanwhile at the aortic isthmus in Type B, but entry point may develop anywhere alongside the entire aorta. All types may affect a short aortic segment resulting in a localized false aneurysm, others separate the intimal layer at longer extension down to the visceral segment and far beyond to the femoral arteries. Dissection of orifices of side branches may lead to cerebral, upper extremity, spinal, visceral, renal and lower extremity malperfusion...

A 69-year-old woman was referred to our hospital due to dyspnea on exertion and a heart murmur. A chest X-ray showed a bulge at the left 3rd arch and chest computed tomography( CT) revealed a giant mass adjacent to the right ventricular outflow. Multidetector-row CT and coronary angiography showed a giant coronary aneurysm (55×45 mm) and fistulae arising from the left main coronary trunk and entering into the main pulmonary artery (PA). The pulmonary to systemic flow ratio was 1.84. She was diagnosed with coronary-pulmonary artery fistulae with giant coronary aneurysm...

Aortic dissection is a life-threatening condition in which early diagnosis, treatment and close follow up are critical for survival. Between 60% and 70% of patients with acute aortic dissection are affected at the ascending aorta, classified as Stanford type A (TAD). Preventive surgery of the aorta in asymptomatic patients on the basis of aortic size alone remains controversial among patient populations without known risk factors for aortic dissection. In fact, many dissection patients do not appear to have markedly dilated aortas at the time of presentation...

OBJECT: To create a novel procedure that will decrease the mortality of experimental animals in the intra-arterial infusion of elastase abdominal aortic aneurysm model. METHODS: Novel models were created by means of direct puncture the infrarenal abdominal aortic aorta, intraluminal elastase in the 1cm segment of abdominal aorta. Femoral artery cannula approach and infusing with elastase was considered as the traditional group, and that infusing with saline solution as the control group...

BACKGROUND: Alternative access for thoracic endovascular aortic repair (TEVAR) has been explored for patients with unsuitable femoral and iliac access, but few cases of transapical access have been described. We report our experience with transapical access for various aortic pathologies. METHODS: We reviewed six cases undergoing transapical access for endovascular repair of thoracic aortic pathology between December 2013 and August 2015. Five patients had an aortic arch aneurysm and 1 patient presented with Stanford type A subacute aortic dissection...
