We report a coil embolization -assisted thoracic endovascular aortic repair technique successfully applied to multiple saccular descending aortic aneurysms in a 74-year-old man. Due to the most distal aneurysm being located at the celiac trunk level and the distance between the superior mesenteric artery and the aneurysm being only 10mm, a coil embolization of the distal saccular aneurysm was performed prior to stent delivery to secure a sufficient landing zone. Postoperative computed tomography showed an appropriate positioning of the endovascular devices without endoleak...

PURPOSE: to describe the use of the combination of a conical custom-made TREO® (TREO CM) stent-graft in the treatment of a saccular abdominal aortic endograft (AAA) with long but tight and calcified distal neck. TECHNIQUE: A 65-year female patient was treated for a saccular 5.2 cm AAA with a 3cm-long but calcified and tight (16mm) distal neck, precluding the safe use of a bifurcated endograft. Since the patient refused an open surgery, a conical TREO CM endograft was manufactured with 20% proximal oversizing, whereas the 3cm caudal sealing segment demonstrated a conical configuration comprised of a 2cm and 1cm nitinol-supported zones of 20% and 10% oversizing, respectively, in order to avoid excessive strain and incomplete expand at the most distal calcified area, leading ultimately to an insidious infolding and consequent type Ib endoleak...

In adult the patent ductus arteriosus is a rare condition associated sometimes with lethal complications. We describe the case of a 44-year-old woman with a history of systemic lupus erythematosus admitted to our hospital with hoarseness and severe dyspnea. Clinical imaging examinations indicated a saccular aneurysm within a persistent ductus arteriosus with signs of impending rupture. Patient was not considered suitable for transcatheter closure and therefore she underwent open aortic repair. The procedure was uneventful and any significant complications occurred during postoperative course...

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...

This study aims to quantify the effects of geometry and stiffness of aneurysms on the pulse wave velocity (PWV) and propagation in fluid-solid interaction (FSI) simulations of arterial pulsatile flow. Spatiotemporal maps of both the wall displacement and fluid velocity were generated in order to obtain the pulse wave propagation through fluid and solid media, and to examine the interactions between the two waves. The results indicate that the presence of abdominal aortic aneurysm (AAA) sac and variations in the sac modulus affect the propagation of the pulse waves both qualitatively (eg, patterns of change of forward and reflective waves) and quantitatively (eg, decreasing of PWV within the sac and its increase beyond the sac as the sac stiffness increases)...

AIM: To describe our experience with the endovascular treatment of focal abdominal aortic pathology with an adequate distal neck length using Endurant (Medtronic) aortic extension cuffs. METHODS: From July 2010 to May 2015, 16 patients (14 male), with a mean age of 73.6 years (range 59-88), were treated for focal abdominal aortic pathology using only Endurant (Medtronic) aortic cuff extensions. The indication for intervention was a saccular abdominal aortic aneurysm (AAA) in 5 patients, a fusiform aortic aneurysm in 6, abdominal aortic dissection in 2, an aortic juxtarenal rupture in one, a large anastomotic pseudoaneurysm of previous bifurcated open repair in one, and a juxtarenal aneurysm above a previous open AAA repair...

Although there are several mitral valve aneurysm reports, studies on aortic valve aneurysm are extremely rare. This paper describes an uncommon case of a large saccular aortic valve aneurysm associated with infective endocarditis. A 37-year-old man was hospitalized in our hospital with fever and dyspnea. Echocardiography found severe aortic regurgitation and aortic valve aneurysm of the non-coronary cusp going in and out of the left ventricular chamber. Blood cultures grew Streptococcus viridance. Therefore, the patient underwent aortic valve replacement...

An aneurysm of the ductus arteriosus is a rare finding, particularly in the adult population. These saccular aneurysms arise at the site of an incompletely obliterated ductus arteriosus along the lesser curvature of the aortic arch. Left untreated, it is associated with a high risk of potentially life-threatening complications including rupture, infection and thromboembolism. As a result, surgical correction is recommended. Previously, options were limited to open repair but as endovascular experience grows, novel techniques afford safer and less invasive alternatives...

Coxiella burnetii, the etiologic agent of Q fever, has been associated with vascular infection and aneurysm formation. We report the case of a 36-year-old woman from Iraq who presented with long-standing malaise as well as vague chest and shoulder discomfort and was found to have a saccular aneurysm of the descending thoracic aorta. Serology assays were positive for chronic C burnetii infection. She was treated with successful aneurysm resection and aortic replacement with a rifampin-impregnated Maquet Hemashield (TM) Dacron interposition graft interposition graft in addition to 18 months of doxycycline and hydroxychloroquine...

Aneurysms of aortic arch are rare but amenable to endovascular therapy. Arch aneurysm presenting with aorto-esophageal fistula and hematemesis is a feared, but relatively rare complication. The extrapolation of the safety and rapidity of emergent endovascular repair for bleeding arch aneurysms has been infrequently reported. A bovine arch anatomy confers distinct advantages for endovascular therapy often avoiding a preceding debranching surgery. However, its endovascular treatment might be complicated by the nonhealing of fistula and potential risk for mediastinitis...
