1/32. aortitis with multiple aneurysms mimicking infective endocarditis.

aortitis usually produces aortic insufficiency by aortic root dilation. In rare cases the inflammation may involve the aortic valve cusps, causing valvular insufficiency. A patient in whom aortitis produced valvular masses, with aortic and peripheral arterial aneurysms, embolic episodes and aortic insufficiency is described. Valve replacement for suspected infective endocarditis was complicated by homograft dehiscence and multiple false aneurysms. Although immunosuppression was successful in decreasing the patient's vasculitis, he became infected and died of complications of aspergillus infection.

2/32. Sudden death associated with aortitis and fibrosclerosing disease of the conduction system.

aortitis is known to complicate a number of autoimmune diseases and syphilis. In most patients with autoimmune disease, arthritis is the initial presentation followed by aortic insufficiency. We report two cases of ostensibly healthy, middle-aged men in whom the initial manifestation of aortitis was sudden death. In each patient, there was extension of inflammation from the aorta into the atrioventricular node. These cases emphasize the importance of examining the conducting system in cases of sudden death associated with aortitis and no grossly evident cause of death. To our knowledge, this is the first report of aortitis presenting as sudden death.

3/32. Caval and ureteral obstruction secondary to an inflammatory abdominal aortic aneurysm.

Inflammatory abdominal aortic aneurysms (IAAA) represent 3% to 10% of all abdominal aortic aneurysms. Obstructive uropathy is a well-described feature of IAAAs, but venous complications are unusual secondary to IAAA. The authors report a patient presenting with acute renal failure and deep venous thrombosis secondary to an IAAA. We believe this represents the first case of an IAAA manifesting as combined inferior vena cava compression and associated obstructive uropathy. Successful operative repair was performed. With resolution of the retroperitoneal inflammation, long-term follow-up revealed spontaneous release of both ureteral and caval compression.

4/32. Behcet's aortitis and aortic regurgitation: a report of two cases.

Behcet's disease is a rare systemic vasculitis that may lead to neurologic complications and rare manifestations of aortitis and aortic regurgitation. We report 2 cases of Behcet's aortitis and aortic regurgitation. The first patient presented with acute stroke. Recognition of acute aortitis on echocardiography led to the diagnosis of vasculitis as the cause of the cerebral event. This case highlights the echocardiographic features of aortic root pathology from acute aortitis to subsequent aortic valve perforation. In both cases, severe aortic regurgitation necessitated aortic valve replacement. Both were complicated by valve dehiscence requiring reoperation, illustrating the postoperative morbidity in this inflammatory condition.

5/32. aortitis and bilateral ureteral obstruction after endovascular repair of abdominal aortic aneurysm.

A bifurcated stent graft was used to treat an asymptomatic 5.4-cm abdominal aortic aneurysm in a 76-year-old man. No endoleaks or inflammatory changes were seen on the 1-month follow-up computed tomography scan. Five months later the patient had acute renal failure and ureteral obstruction secondary to significant inflammatory changes in the aneurysm wall. After bilateral ureteral stenting, conservative treatment included tamoxifen and steroid therapy. The patient remains symptom-free, and at 2-year follow-up a computed tomography scan demonstrated decreased inflammation and shrinkage of the excluded abdominal aortic aneurysm.

6/32. GRAFT infection of thoracic aorta due to group C beta-hemolytic streptococcus--a case report.

A fatal case of late-onset graft infection of the thoracic aorta due to group C beta-hemolytic streptococcus is described. A 37-year-old male patient, who had a history of total aortic arch replacement for acute aortic dissection 8 years before, was admitted to the department. He suffered from toxic shock syndrome, disseminated intravascular coagulation (DIC), and acute renal failure. Group C beta-hemolytic streptococcus was detected from his blood; however, echocardiography, computed tomography (CT), and magnetic resonance imaging (MRI) failed to detect the focus of the infection. In spite of intensive care, including antibiotic therapy, artificial ventilation, and continuous hemodiafiltration, he died on the 18th day of hospitalization. autopsy revealed that a small abscess was present at the proximal anastomotic segments of the patient's graft. A bite inflicted by his dog, 14 days before admission, was suspected to be the source of this bacterium. A rare case of graft infection of thoracic aorta in terms of causative organism, long period from graft replacement to graft infection, and site of infection is presented and discussed.

7/32. A rare presentation of cardiac hydatid cyst: stroke and acute aortic occlusion.

Cardiac involvement in hydatid disease is uncommon. We report a case of a surgically treated ruptured left ventricular hydatid cyst, which presented with acute stroke and was later complicated by distal aortic embolism due to perioperative dislodgement of the germinative membrane.

8/32. Cardiovascular involvement in Crohn's disease in the absence of ankylosing spondylitis.

We describe a patient who had aortic regurgitation associated with Crohn's disease in the absence of ankylosing spondylitis. aortitis and aortic insufficiency are fairly uncommon in Crohn's disease. The patient required aortic valve replacement because of severely uncoated cusps secondary to inflammation of the aortic wall and aortic valve. There was a saccular formation just above the right non-coronary commissure. This sac was closed with a pericardial patch. Pledgeted sutures were used for implantation of the prosthetic valve to avoid periprosthetic leakage. The right coronary ostium had narrowed due to aortic wall thickening. A right internal thoracic artery to right coronary artery bypass was done since there was no necessity for proximal anastomosis.

9/32. Takayasu aortitis with acute dissection and hemopericardium.

We report a case of a 57-year-old woman with an unremarkable past medical history who presented to the emergency department with maxillary pain that later radiated to the chest. She died less than 12 h after admission. CT findings were consistent with ascending aorta dissection with hemopericardium. autopsy revealed a tear immediately proximal to the ostium of the brachiocephalic artery and a dissecting flap with false lumen, rupture, and hemopericardium. Histologically, there was a zonal medial necrosis with surrounding chronic inflammation, focal destruction of the media, and fibrosis of the intima and adventitia. A diagnosis of granulomatous necrotizing aortitis of Takayasu type was made. This case demonstrates a rare example of aortitis underlying aortic dissection and emphasizes the need for careful histologic examination in cases of aortic root disease.

10/32. The inflammatory abdominal aortic aneurysm and coronary artery disease. Case report and review.

Inflammatory abdominal aortic aneurysm (IAAA) is defined as an unusually thickened aneurysmatic wall, encircled by a wide dense perianeurysmal and/or retroperitoneal fibrosis with adjacent tissues adhesion, and is now considered as an extreme shape of the common phlogistic process involved in atherosclerotic plaque formation. Latest studies demonstrated that inflammation plays an important role in coronary disease and in other atherosclerosis manifestations. We introduce the clinical case of a patient with IAAA who developed an acute myocardial infarction 6 months after the surgical procedure on the aorta. Through a literature review about IAAA we stress the clinical usefulness of the inflammatory markers as independent predictors in management of patients with coronary disease and we present the hypothesis, related to the introduced case, of an advanced coronary disease, aggravated or clinically revealed after the cytokine storm related to important localized inflammatory engagements or great vascular surgery treatments.
