It poses a high risk of complications such as aneurysm rupture, uncontrolled sepsis and extensive periaortic infection. Symptoms are frequently minimal during the early stages and a high index of suspicion is essential to make the diagnosis. They are more likely to expand rapidly and rupture without surgical intervention. We report a case of a middle-aged man presented with 3-week history of fever, abdominal pain and low back pain. Initially presented as acute pyelonephritis with subsequent findings of liver abscess, right epididymoorchitis and left infrarenal mycotic aneurysm, which rapidly increased in size and underwent successful endovascular surgery.展开更多

Aortic dissection in young patients, however, is fortunately rare. We report a case of giant ascending aortic aneurysm with Stanford type A aortic dissection in an otherwise well 22-year-old male patient. Operative aortic valve and root replacement was undertaken with favourable outcome. Histopathologic examination of the resected aorta revealed acute on chronic inflammatory change with Langerhans type giant cells consistent with a diagnosis of giant cell aortitis. While uncommon, emergencies of the aorta may present in young patients. Predisposing conditions are discussed.展开更多

HRCT and CTA were performed before or after 1 or 12 mo respectively to EVAR in all patients. All HRCT examinations were reviewed by two radiologists with 15 and 8 years experience in thoracic imaging. The results were compared with histology, bronchoscopy or follow-up HRCT in 12, 8 and 82 nodules respectively. RESULTS There were a total of 102 suspected nodules in 92 HRCT examinations, with a mean of 1.79 nodules per patient and an average diameter of 9.2 mm(range 4-56 mm). Eightynine out of 181 HRCTs resulted negative for the presence of suspected nodules with a mean smoking history of 10 pack-years(p-y, range 5-18 p-y). Eighty-two out of 102(76.4%) of the nodules met criteria for computed tomography follow-up, to exclude the malignant evolution. Of the remaining 20 nodules, 10 out of 20(50%) nodules, suspected for malignancy, underwent biopsy and then surgical intervention that confirmed the neoplastic nature: 4(20%) adenocarcinomas, 4(20%) squamous cell carcinomas, 1(5%) small cell lung cancer and 1(5%) breast cancer metastasis); 8 out of 20(40%) underwent bronchoscopy(8 pneumonia) and 2 out of 20(10%) underwent biopsy with the diagnosis of sarcoidosis.CONCLUSION HRCT in EVAR planning and follow-up allows to correctly identify patients requiring additional treatments, especially in case of lung cancer.展开更多

It is generally linked to congenital heart defects or connective-tissue diseases. Our case is a 10-year-old girl admitted in the pediatric emergency care unit on January 19th, 2015 for massive haemoptysis and severe anaemia. Examination revealed severe anemia and a silent left lung. The Chest X-Ray revealed an abnormal mass on the upper left side of the mediastinum, and left lower lobe consolidation. The thoracic CT scan highlighted a 64 mm aneurysm of the subisthmic aorta with a thin 5 mm hole. It also showed pseudocoarctation of the aorta. Treatment in intensive care consisted of blood transfusion and iron supplement. She was due to travel abroad for cardio vascular surgery, but died on November 2016. Thoracic Aortic Aneurysm in our setting was discovered incidentally. In spite the fact that it is an extreme surgical emergency, in Burkina Faso, treatment can only be possible abroad upon medical evacuation.展开更多

Presentation of Case: A 78-year-old known hypertensive and asthmatic woman of 25 and 10 years duration respectively. She had an untreated degenerative aortic valve lesion and moderate aortic regurgitation. This case study showed the complex interplay of background untreated aortic valve disease, aortic insufficiency, chronic hypertension, chronic airway obstructive disease and ageing in a case of giant aneurysm of the entire ascending aorta. It also emphasizes the role of imaging in diagnosis and follows up of ascending aortic aneurysm particularly where prevention is key to prevent the high mortality associated with Thoracic aneurysymal rupture. Conclusion: Timely institution of appropriate treatment of aortic valve disease, prevention and adequate control of hypertension is key to prevent the development and the grave prognosis of ascending aortic aneurysm, particularly in the developing world where appropriate medical facilities, expertise and treatment are scarce.展开更多

This surgery consists of resection of the aneurysm, debridement and revascularization with an in situ or extra-anatomic bypass. Even when surgery has been successful, the morbimortality is raised and the endovascular treatment has become an alternative for specific patients. When mycotic aneurysms involved the visceral arteries, more complex techniques are necessary such as fenestrated endovascular aortic repair or chimmeny endovascular aortic repair and the most frequent complications of this are endoleaks and oclussion the visceral arteries. We present a case of a pacient with a paravisceral abdominal mycotic aneurysms that was result with 2 chimney technique(in the right renal and superior mesenteric arteries) and a single Nellix EVAS(Endologix, Irvine, Calif) of 12 cm long without evidence of endoleaks in the follow-up.展开更多

We report a case of treatment of an abdominal aortic aneurysm with a bifurcated stent, complicated by total thrombosis. Aim: The purpose of this presentation was to understand the causes, mechanisms, incidents and accidents that contributed to this complication. Case Presentation: A 48-year-old man patient with a history of high blood pressure, ischemic heart disease, chronic obstructive pulmonary disease, who was found during a surveillance check-up, an infra-renal abdominal aorta aneurysm measured at 56 mm in diameter, asymptomatic but progressive. The indication of an endovascular treatment by the placement of a bifurcated prosthesis was posed and accepted. Thrombosis of the two limbs was intra-operative, upper-end migration without endoleak at 4 months postoperative, total thrombosis of the stent at 13 months postoperatively. Explantation of the stent followed by aortobi-iliac bypass was finally performed in the 15th month. Conclusion: The cardiopulmonary antecedents, the anatomical and evolutionary characteristics of the aneurysm could have played a role in the occurrence of the complications observed in this patient.展开更多

In spite of advances in endovascular techniques, surgery remains the treatment of choice in the majority of cases. We report the case of a huge pseudoaneurysm caused by late dehiscence of the right coronary ostium-aortic tubular graft anastomosis, occurred 30 years after replacement of aortic valve and ascending aorta by classical Bentall operation. A fistula originating from the aneurysmal sac extended across the sternum into the thoracic subcutaneous soft tissues and gave rise to a pulsatile mass well appreciable on the anterior chest wall. The surgical treatment, consisting of partial resection of the aortic tubular graft and sternal reconstruction was effective and uneventful.展开更多

When etiopathogenetic associations among changes observed during the progression of the disease were not fully described, surgeons had successfully applied, although traumatic, but a rather radical method to rescue from the rupture threat. As we gained experience and knowledge about long-term outcomes, mostly concerned mortality, we realized that surgery could not be the main tactical approach to AAAs treatment due to its frequent inefficiency and failure to guarantee that the disease would be suppressed including co-morbidities, polymorphic processes and clinical manifestations. It all required more sparing treatment strategies. The situation gave rise to a more argumentative and sparing medical-and-surgical approach to treatment based on a more in-depth understanding of the etiopathogenesis of the disease whereas surgery would remain of prime importance when appropriate. The following has been developed to improve treatment outcomes for AAA: 1) Multifactorial determination of indications for surgical correction with outlining the area of relative and absolute risk of aneurysm rupture;2) Method of conservative treatment aimed to attain and maintain optimal blood pressure, target levels of cholesterol and low-density lipoproteins, as well as reduce oxidative and inflammatory processes in aorta, strengthen its wall, stabilize the disease and control co-morbidities. A four-year follow-up of patients using this developed technology has yielded more preferred results suggesting the need for narrowing indications for surgery to treat AAAs. Another advantage of the sparing approach to treat AAA is economic, due to fewer operations and implantations of stent-grafts, considering the fact that medical treatment should be used in operated subjects, too.展开更多

The incidence of thoracic aortic aneurysms is estimated at 4.5 cases per 100,000. The diagnosis is often made on a chest x-ray or other imaging tests, such as an echocardiogram done for other heart diseases. Echocardiography is the first test to assess the diameter of the ascending aorta and its progression over time. Most patients are first assessed and followed up with spiral thoracic computed tomography with injection of contrast medium, supplemented by 3-dimensional reconstruction of the aneurysm in order to improve the accuracy of measurements, identification of its proximal part and distal. When dilation of the ascending aorta reaches the critical diameter of 50 mm, there is a risk of aortic dissection or rupture. Supravalvular aneurysms are treated by replacing the ectatic portion with a Dacron<span style="white-space:nowrap;">®</span> tube in the supracoronary position. Aortic root aneurysms, including coronary ostia, require tube replacement, reimplantation of coronary ostia, as well as surgery on the aortic valve. In this article, we report a case of aneurysm of the aortic root and the ascending aorta treated by aortic valve replacement and the ascending aorta associated with the Cabrol hemi-mustache technique and we review the literature.展开更多
