Endo vascular aortic repair [EVAR] is performed with low peri-operative morbidity and mortality rate and short hospital stay. However, EVAR needs a close and lifelong imagining surveillance for a timely detection of possible complications including endoleaks, graft migration, fractures, and enlargement of aneurysm sac size with eventual rupture. Contrast enhanced computed tomography [CTA] is actually considered the gold-standard in EVAR follow-up, but it is accompanied with radiation burden and renal injury due to the use of contrast media...

OBJECTIVE: We evaluated the effect of close contact between the stent and the graft on the induction of endothelial covering on the stent graft placed over an aneurysm. MATERIALS AND METHODS: Saccular abdominal aortic aneurysms were made with Dacron patch in eight dogs. The stent graft consisted of an inner stent, a expanded polytetrafluoroethylene graft, and an outer stent. After sacrificing the animals, the aortas with an embedded stent graft were excised. The aortas were inspected grossly and evaluated microscopically...

A 77-year-old woman was admitted to a hospital with complaints of back pain, nausea and vomiting for 4 days. She underwent enhanced aortic computed tomography (CT) and was diagnosed with Stanford type A acute aortic dissection. Then she was transferred to our hospital. CT showed aortic dissection spreading from the ascending aorta up to the abdominal aorta and an intimal tear located at the descending thoracic aorta. Although the false lumen of the ascending aorta was thrombosed, emergency ascending aorta replacement and aortic valve replacement were performed, because pericardial effusion and severe aortic regurgitation were found by echocardiography...

A 44-year-old man with Eisenmenger's syndrome due to ventricular septal defect (VSD) was listed for lung transplantation. The patient's condition was complicated by a giant pulmonary artery (PA) aneurysm. Concurrent VSD closure and total reconstruction of the recipient PA with the donor aorta were planned. When the patient underwent bilateral lung transplantation, the aortic graft obtained turned out to be too short to complete the reconstruction. A PA graft made of the recipient's pericardium was successfully interposed between the donor's PA and the donor's aortic graft...

SESSION TYPE: Pleural Cases IPRESENTED ON: Tuesday, October 23, 2012 at 11:15 AM - 12:30 PMINTRODUCTION: The most common cause of hemothorax is trauma. Non-traumatic hemothorax is uncommon and can be caused by malignancy, tuberculosis, blood dyscrasias, pulmonary embolism, thoracic aortic aneurysm, pulmonary artery aneurysm, arteriovenous fistula, connective tissue disease, and catamenial hemothorax. We present the case of a patient who developed a hemothorax as a result of a costal exostosis: a rare cause of spontaneous hemothorax...

Resection of the infected aorta, debridement of the surrounding tissue, in situ graft replacement, and omentopexy is the standard procedure for treating infected aortic aneurysms, but the question of which graft material is optimal is still a matter of controversy. We recently treated a patient with an infected thoracic aortic aneurysm. The aneurysm was located in the proximal aortic arch. Because the patients had previously undergone abdominal surgery, the aortic arch were replaced in situ with a branched equine pericardial roll grafts...

OBJECTIVE: The mechanisms underlying abdominal aortic aneurysm development remain unknown. We hypothesized that acceleration of glucose metabolism with the upregulation of glucose transporters is associated with abdominal aortic aneurysm development. METHODS AND RESULTS: Enhanced accumulation of the modified glucose analogue 18 fluoro-deoxyglucose by positron emission tomography imaging in the human abdominal aortic aneurysm was associated with protein expressions of glucose transporters-1 and -3, assessed by Western blot...

With data from four randomized trials on elective endovascular abdominal aortic aneurysm repair and many more additional post-hoc publications, the evidence can be somewhat overwhelming for the surgeon, let alone the patient. This chapter aims to present the most recent and relevant data for decision making in abdominal aortic aneurysm (AAA) repair in a comparative and concise format. After a comparison of the short- and long-term survival data of the randomized trials, the following post-hoc analyses of the four randomized trials will be presented: causes of death, reinterventions, renal function, prediction of complications, and quality of life...

The treatment of Aortic Aneurysm disease is a growing procedure due to increase of life expectancy in Western Countries and relative incidence. In the past ten years we observed a progressive growth of endovascular over open surgery procedures with a related decline in rupture related deaths. Endo Vascular Aortic Repair [EVAR] is a well known technique of treatment of abdominal aortic aneurysms, that has changed the surgical approach to abdominal aortic aneurysms, as it is performed with low perioperative morbility and mortality rate and shorter hospital stay...

This study evaluated the usefulness of computed tomography (CT) angiography for the detection of high-risk aortas for carotid artery stenting (CAS). We investigated changes in the treatment method and modifications of endovascular techniques according to the information from CT angiography. CT angiography using three-dimensional and multi-planar reconstruction was performed in 43 consecutive patients with carotid artery stenoses intended to undergo CAS. Two neurosurgeons evaluated the images and estimated the risk and difficulties of CAS...

Abdominal aortic aneurysm (AAA) is a common disease caused by segmental weakening of the aortic walls and progressive aortic dilation leading to the eventual rupture of the aorta. Currently no biomarkers have been established to indicate the disease status of AAA. Tenascin-C (TN-C) is a matricellular protein that is synthesized under pathological conditions. In the current study, we related TN-C expression to the clinical course and the histopathology of AAA to investigate whether the pattern of TN-C expression could indicate the status of AAA...

AIM OF THE STUDY: This article summarizes our experience in endovascular repair of abdominal aortic aneurysm in octogenarian patients. MATERIAL AND METHODS: From January 2000 to December 2005 30 patients (mean age 84 years) underwent endovascular repair of abdominal aortic aneurysm; in 28 cases a loco-regional anaesthesia has been performed. Twenty-eight bifurcated graft, one straight graft and one aorto-iliac graft have been used. RESULTS: No operative mortality or early endoleak have been observed; during the follow-up period (20 months) 7 endo-leaks (3 cases type I; 4 cases type II) have been reported; all patients with type I EL underwent endovascular repair; in two patients with type II EL we observed spontaneous regression; the other cases are still monitored in absence of sac enlargement...
