A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

OBJECTIVE: Low wall shear stress (WSS) has been reported to be associated with accelerated atherosclerosis, aneurysm growth, or rupture. We evaluated the geometry of aortic arch aneurysms and their relationship with WSS by using the 4-dimensional flow magnetic resonance imaging to better characterize the saccular aneurysms. METHODS: We analyzed the geometry in 100 patients using multiplanar reconstruction of computed tomography. We evaluated WSS and vortex flow using 4-dimensional flow magnetic resonance imaging in 16 of them, which were compared with 8 age-matched control subjects and eight healthy young volunteers...

We describe the successful surgical treatment of an impending rupture of a saccular descending thoracic aortic aneurysm and accompanying compression of the left main bronchus. A 69-year-old man presented with a history of tingling chest pain lasting for a few hours. His left lung cannot be auscultated, and he was rapid progression of dyspnea. Computed tomography (CT) showed a saccular aneurysm compressing the left main bronchus. The patient was treated with conventional open surgery. The compression was immediately released...

INTRODUCTION: Aortitis is a well recognized manifestation of the tertiary stage of syphilis. EVIDENCE ACQUISITION: Although often regarded as an unexpected diagnosis, actually new cases of cardiovascular syphilis continue to be reported. Presumably, Treponema pallidum invades the aortic wall and the inflammatory response progresses towards obliterative endarteritis and necrosis of the muscular and elastic fibers in the aortic media. The consequent weakening of the aortic wall can lead to severe complications, represented by aortic aneurysm, aortic valvular insufficiency, aortic root dilation and coronary ostial stenosis...

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. Because of the most distal aneurysm being located at the celiac trunk level and the distance between the superior mesenteric artery and the aneurysm being only 10 mm, a coil embolization of the distal saccular aneurysm was performed before stent delivery to secure a sufficient landing zone. Postoperative computed tomography showed an appropriate positioning of the endovascular devices without endoleak...

BACKGROUND: 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. MATERIALS AND METHODS: A 65-year-female patient was treated for a saccular 5.2 cm AAA with a 3-cm long but calcified and tight (16 mm) distal neck, precluding the safe use of a bifurcated endograft. Because the patient refused an open surgery, a conical TREO CM endograft was manufactured with 20% proximal oversizing, whereas the 3-cm caudal sealing segment demonstrated a conical configuration comprising a 2-cm and 1-cm nitinol-supported zones of 20% and 10% oversizing, respectively, 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...

BACKGROUND: In a patient underwent aortic valve replacement (AVR) due to bicuspid aortic valve (BAV) insufficiency without marked dilation of ascending aorta, the development of delayed-typed aneurysmal complication of ascending aorta has been often reported because the dilated aorta tends to grow insidiously with age. CASE SUMMARY: A 58-year-old man who underwent AVR with mechanical valve due to severe aortic regurgitation secondary to BAV 7 years previously presented with exertional chest discomfort for 1 year...

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)...

BACKGROUND: 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 patients, abdominal aortic dissection in 2 patients, an aortic juxtarenal rupture in 1 patient, a large anastomotic pseudoaneurysm of previous bifurcated open repair in 1 patient, 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...
