Etiology of saccular aortic aneurysms

An abdominal aortic aneurysm (AAA) is a confined dilatation involving the abdominal aorta. The incidence is rare and the etiology is unknown. Cases associated with conditions like Kawasaki, connective tissue, Behcet's diseases, and vasculitis are considered acquired. Our patient had a clinical criterion of Behcet's disease. Management involves a surgical approach. Endovascular intervention is not an option here, as the aneurysm is close to the bifurcation evident in computed tomography angiogram scans. Usually, they have good long-term outcomes...

Mycotic aneurysms are a rare complication of systemic infections, where the arterial vessel wall becomes dilated secondary to bacterial, fungal, or viral infection. The incidence of mycotic aneurysms is rare but carries a significant mortality risk. Patients with mycotic aneurysms can have wide-ranging clinical presentations depending on the site of the aneurysm. Our case discusses one of the most encountered emergency department (ED) presentations, i.e., nausea and vomiting, as a presenting symptom of a patient found to have a mycotic aneurysm...

Infectious aneurysms, formerly known as mycotic aneurysms, are rare, most often involve the aorta in young patients, and have a greater tendency to rupture than aneurysms of other etiologies. The most characteristic shape is saccular and the most common etiologic agents are Staphylococcus sp. and Salmonella sp . There is scant and imprecise information in the literature about correct nomenclature, diagnosis, and treatment. The authors present three cases in which diagnostic and therapeutic procedures were documented...

Aortitis is the inflammation of the aorta secondary to either infectious or non-infectious etiologies. Infectious aortitis is a rare but potentially life-threatening condition. It is more common among older patients with preexisting pathology. Clinical presentation is variable, therefore, a high index of suspicion is required for timely diagnosis and management. We report a case of aortitis which was complicated with the development of a saccular abdominal aortic aneurysm. A 76-year-old male presented to the Emergency Department with two days of right lower quadrant abdominal pain...

Mycotic aneurysms, often saccular, accounting for approximately 2.5% of all abdominal aortic aneurysms, possess increased risk of rupture, uncontrolled sepsis, and protracted hospital stay and are associated with high morbidity and mortality. The authors report the case of a 49-year-old female with no known comorbidities who presented with free rupture of an infrarenal dissecting mycotic aneurysm and underwent emergent open repair successfully. The etiological agent, Brucella melitensis , a Gram-negative zoonotic coccobacillus, is rarely reported to cause mycotic aneurysm...

Behçet disease is a multisystem disorder presenting with recurrent oral and genital ulcerations as well as with ocular involvement. Vascular involvement can occur in up to 50% of affected patients. Arterial aneurysms are often multiple and are characterized by a saccular configuration with increased risk of unexpected rupture, thrombosis, and aneurysm recurrence. Here we report a case of giant infrarenal abdominal aortic aneurysm in a 34-year-old man with Behçet disease who underwent aneurysmorrhaphy and aortobifemoral bypass...

INTRODUCTION: Thoracic endovascular aortic aneurysm repair (TEVAR) is an established treatment for thoracic aortic disease in both the acute and elective setting, with such a widespread use that almost 50% of all thoracic aortic surgery in Europe is performed by these means. Nonetheless, the feasibility of TEVAR is determined by several anatomic factors, and the suitability of the proximal and distal landing zones remain one of the main limitations to its use. The advent of custom-made thoracic stent grafts widened the endovascular options in some challenging anatomies...

BACKGROUND: The 1-year results of endovascular exclusion of degenerative descending thoracic aortic aneurysms (DTA) with the Valiant Thoracic Stent Graft (Medtronic Vascular, Santa Rosa, Calif) have been previously reported. With long-term follow-up now complete, the 5-year results are reported. METHODS: The VALOR II trial (Evaluation of the Clinical Performance of the Valiant Thoracic Stent Graft System in the Treatment of Descending Thoracic Aneurysms of Degenerative Etiology in Subjects Who Are Candidates for Endovascular Repair) was a prospective, nonrandomized trial of the Valiant Thoracic Stent Graft system in patients with degenerative DTA...

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...

Saccular aneurysms of the aortic arch, whether single or multiple, are uncommon. The choice of repair technique is influenced by patients' comorbidities and age. Repairing saccular aneurysms with traditional open techniques can be technically demanding; therefore, endovascular technology and a variety of hybrid approaches have been developed to facilitate such repairs and, potentially, to improve clinical outcomes, especially in high-risk patients. There have been no large, randomized studies to compare the outcomes of these different treatment options in patients with single or multiple saccular aneurysms of the arch...

Tropical aortitis is a rare and poorly described aortic disease, sometimes confounded with Takayasu's disease, mainly in people from Africa. In this case report, the panaortic aneurysmal disease in a young woman from Haiti, first diagnosed after a work-up on renovascular hypertension, would appear to approach this particular arterial disease with no clinical, radiological or biological argument for an infectious etiology. The initially suspected diagnosis of Takayasu's disease had to be rethought because of the presence of several saccular aneurysms extending from the aortic arch to the infrarenal aorta, rarely described in Takayasu's aortitis...

We report an autopsy case of bronchial asthma patient with a specific abdominal aortic aneurysm. The aneurysm did not show arteriosclerosis, and a specific saccular morphology was noted above the bifurcation. Histologically, necrosis of the media resembling acute aortic dissociation was observed. However, angiitis was ruled out. In addition, the aneurysm showed a cicatrized, old intimal crack in addition to the rupture site, suggesting repeated failures. The long-term steroid therapy-related fragility of the arterial wall may have been involved in the etiology of the aneurysm...

PURPOSE: To report the use of multilayer uncovered stent to treat primary infected juxtarenal aortic aneurysm. CASE REPORT: A 50-year-old man was admitted to hospital for rapid onset of intractable abdominal pain and high fever. Computed tomographic scan showed 2 juxtarenal saccular aneurysms of abdominal aorta with morphologic and clinical changes compatible with infectious etiology. Patient was treated with multilayer flow-modulating stent. Follow-up imaging showed persistent aneurysm exclusion and continuous aneurysm shrinkage of the sac until complete regression to a normal aortic configuration was seen at 1 year...

True aneurysm formation in arterialized autologous veins is an unusual complication. A saccular aneurysmal degeneration of 53 mm (maximal diameter) of a saphenous vein graft inserted for repair of a popliteal aneurysm, four years after implantation, is reported. The patient (with prior history of abdominal aortic aneurysm) had been initially treated through a posterior approach. A new saphenous vein bypass grafting (medial approach) was performed. Histological examination revealed myointimal fibrosis, medial degeneration and inflammation...

Pseudocoarctaion is a rare congenital anomaly due to elongation of aortic arch. The exact etiology is still uncertain. It may be associated with other congenital cardiac and vascular anomalies. We report an unusual case of pseudocarctation associated with aberrant right subclavian artery, left SVC and multiple saccular aneurysms in the kinked arch and we feel that this is the first documented case in literature.

Inflammatory abdominal aortic aneurysms (IAAAs) account for 5% to 10% of all abdominal aortic aneurysms, occurring primarily in males. Their true etiology is unknown. Symptoms and signs of IAAA are so variable that they present to a wide range of specialties. There is debate in the literature whether IAAA is a manifestation of systemic autoimmune disease. We describe the case of a young female patient with complicated inflammatory aortoiliac aneurysmal disease, illustrating diagnostic and treatment challenges that remain...

The aneurismatic aortic disease is one of the most frequent conditions challenging the vascular surgeon. It can be caused by atherosclerosis, vasculitis, trauma, infection or others. The treatment, even when elective, can be associated to high rates of morbid-mortality, related to the etiology, anatomic location and type of treatment. The authors describe the case of a patient with concomitant syphilitic aneurysms of the descending thoracic aorta, pararenal and aortic bifurcation. The diagnostic presumption was supported by clinical and epidemiology data (the patient was treated for a syphilitic saccular infrarenal aortic aneurysm 5 years before)...

OBJECTIVE: Immunoglobulin G4-related sclerosing disease (IgG4-SD) has recently been reported to occur in the cardiovascular system and manifest as inflammatory abdominal aortic aneurysm. Thoracic aortic lesions are often associated with aortitis in several divergent etiologies. Thus, this study was performed to review thoracic aortic lesions from the aspect of IgG4-SD and to elucidate the clinicopathologic characteristics of this subgroup in the thoracic aorta. METHODS: The study comprised 125 patients, including 71 with thoracic aortic aneurysm (TAA), 44 with aortic dissection, 7 with Takayasu aortitis, and 3 with infectious aortitis...

An autopsy case of spontaneous rupture of a clinically undiagnosed inflammatory aneurysm of the aortic sinus is presented. A 34-year-old man consulted a physician complaining of anterior chest pain and heartburn persisting for 2 days. Diagnoses of common cold and gastritis were made, but 3h later his condition deteriorated, leading to death. Autopsy revealed hemopericardium due to rupture of a saccular aneurysm of the aortic sinus. Histological examination of the aortic sinus disclosed aortitis characterized by fragmentation and loss of elastic tissues with fibrous thickening of the intima...

PURPOSE: To retrospectively review our experience with visceral artery aneurysms (VAAs) treated with percutaneous coil embolization techniques. METHODS: Patient records were retrospectively reviewed between 1988 and 1998 for VAA cases treated with catheter-based techniques. Nine patients (5 women; mean age 64 +/- 11 years) with 12 (8 false and 4 true) VAAs were identified. The majority (67%) of these patients presented with symptoms of aneurysm rupture. The etiology of the aneurysm was iatrogenic in 4, pancreatitis in 4, and idiopathic in 4...
