We report a case of a compassionate treatment of a ruptured thoraco-abdominal aortic aneurysm in a 92-year-old patient. Patient was admitted to our emergency department for acute onset of pain irradiating to the back. Computed tomographic angiography showed the presence of a thoraco-abdominal aortic aneurysm with a contained rupture at infrarenal level. Given of the presence of a relative healthy visceral aorta, we decided to treat the patient by Ovation(®) (Endologix, Irvine, CA - USA) implantation in an off-label fashion...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

BACKGROUND: These last years, considerable attention has been given to renal issues following endovascular aortic repair (EVAR) but acute kidney injury (AKI) also remains one of the most frequent complications following open repair (OR). OBJECTIVES: Since AKI definition has evolved, our aim was to review the aetiology, incidence, classifications and consequences of AKI after OR for intact abdominal aortic aneurysm (AAA). METHODS: A review of the English language literature published between 2004 and 2016 was conducted according to the PRISMA criteria...

BACKGROUND: Ovation Aortic Stent-Graft System is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid ancored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new desing . Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the Ovation in 3 patients...

OBJECTIVE: Limited data exist comparing perioperative morbidity and mortality after open and endovascular abdominal aortic aneurysm (AAA) repair (EVAR) among regions of the United States. This study evaluated the regional variation in mortality and perioperative outcomes after repair of AAAs. METHODS: The Vascular Quality Initiative (VQI) was used to identify patients undergoing open AAA repair and EVAR between 2009 and 2014. Ruptured and intact aneurysms were evaluated separately, and the analysis of intact aneurysms was limited to infrarenal AAAs...

The implantation of a stiff aortic endograft for endovascular abdominal aneurysm repair (EVAR) has been reported to increase aortic stiffness and pulse wave velocity (PWV), raising potential concern over deterioration of myocardial performance. Yet, additional stiffness indices such as the augmentation index (AIx), reflection magnitude (RM) and changes in augmentation pressure (AP) have not been studied adequately to facilitate and improve our knowledge regarding the ways that EVAR affects central hemodynamics...

Mycotic abdominal aortic aneurysms (MAAAs) are rare entities accounting for 0.65-2% of aortic aneurysms. Campylobacter fetus has a tropism for vascular tissue and is a rare cause of mycotic aneurysm. We present a 73-year-old male patient with contained rupture of a MAAA caused by C. fetus, successfully treated with endovascular aortic repair (EVAR) and antibiotics, which is not previously described for this aetiology. Although open surgery is the gold standard, EVAR is nowadays feasible and potentially represents a durable option, especially in frail patients...

A 76-year-old man who had undergone endovascular repair for an infrarenal aortic aneurysm, presented with a late type Ia endoleak 3 years after his operation. Deployment of an aortic cuff did not achieve a better seal at the proximal neck, and the aneurysm developed a rupture. We successfully treated the ruptured aneurysm using transcatheter Onyx embolization only. At 6-month and 1-year follow-ups with contrast-enhanced duplex scanning, no endoleak was seen and sac shrinkage was observed. Onyx is a relatively new liquid embolic agent that is slowly transformed into a solid state by contact with blood...

REVIEW
Zachary W Kostun, Edward Y Woo
Endovascular aneurysm repair has enabled a broad population of patients with infrarenal abdominal aortic aneurysm to be treated by a less-invasive technique. However, endovascular aneurysm repair has therapeutic limitations, including the need for lifelong surveillance and a higher rate of secondary interventions than open repair. These outcomes can promote patient dissatisfaction and result in increased health care costs and associated morbidity and mortality. The primary reason for secondary interventions is continued abdominal aortic aneurysm sac enlargement due to endoleaks...

New developments in infrarenal abdominal aortic aneurysm stent-graft devices have made more patients eligible for endovascular aneurysm repair (EVAR). Recent US Food and Drug Administration approval for fenestrated endograft repair and impending approval for iliac branch devices extend the proximal and distal landing zones. Better deployment systems allow for partial deployment of endografts to facilitate repositioning, and more flexible designs allow for treatment of angulated infrarenal aneurysm necks and tortuous iliac arteries...

Currently methods to reduce radiation and contrast media application in endovascular repair of aortic aneurysms (EVAR) are investigated. First positive results for real-time contrast medium-enhanced ultrasonography (CEUS) guided endovascular aortic repair have been reported. A combination with image fusion of CEUS and preoperative multi-slice computed tomography (MS-CT) might offer added safety regarding stent-graft positioning and sealing of the landing zones.EVAR was performed in a patient with an asymptomatic infrarenal aortic aneurysm and a penetrating aortic ulcer in the neck region...

OBJECTIVE: A significant reduction in the incidence of cardiovascular disease, including abdominal aortic aneurysm (AAA), has been observed in the past decades. In this study, a small but geographically well defined and carefully characterized population, previously screened for AAA and risk factors, was re-examined 11 years later. The aim was to study the reduction of AAA prevalence and associated factors. METHODS: All men and women aged 65 to 75 years living in the Norsjö municipality in northern Sweden in January 2010 were invited to an ultrasound examination of the abdominal aorta, registration of body parameters and cardiovascular risk factors, and blood sampling...

The central aorta constitutes the main trunk of the systemic arterial tree. It dilates passively with cardiac ejection during systole and then constricts with its recoil function during diastole, thereby regulating blood pressure and blood flow. The central pulsatile hemodynamics affects local hemodynamics within as well as downstream of the aorta (e.g., end organs).The aorta progressively stiffens and dilates with advancing age, and such age-dependent change is accelerated by hypertension. According to the law of Laplace, wall stress depends on the diameter and pressure of the blood vessel...

We herein report a case of a rare complication of spinal cord ischemia (SCI) following endovascular aneurysm repair (EVAR). Computed tomography showed stenosis and calcification of bilateral iliac arteries and a saccular aneurysm of the terminal aorta. Paraplegia occurred soon after balloon angioplasty of iliac arteries and EVAR. Cerebrospinal fluid drainage was not performed because the patient was on dual antiplatelet drugs. The patient was treated with intravenous methylpredonisolone and naloxone; however, this did not improve his paraplegia...
