We report a surgical case of infected thoracic aortic aneurysm. Before arrival of the cryopreserved aortic allograft, the patient had hemoptysis resulting from aneurysm rupture. Therefore endovascular stent grafting was urgently performed three days prior to in situ allograft implantation. Palliative stent grafting prevented circulatory collapse and stabilized the patient until successful allog...

We have been investigating the cardiovascular system over micro to macro levels by using conjugated computational mechanics analyzing fluid, solid and bio-chemical interactions. In the present study, we introduce our recent researches on the mass transport to saccular aneurysm, cerebral aneurysm growth based on a hemodynamic hypothesis, malaria-infected red blood cell mechanics using a particle...

Historically, Streptococcus pyogenes was a common cause of endocarditis and infected aortic aneurysm. Today, endovascular infections due to this organism have become exceedingly rare. We report the first case of aortic aneurysm infection due to S. pyogenes treated with initial endoluminal repair, review previous reports and discuss current treatment options.

Backgound Infected aneurysm (or mycotic aneurysm) is defined as an infectious disease of the wall of an artery with formation of a blind, saccular out-pouching that is contiguous with the arterial lumen. Symptoms are frequently absent or non-specific during the early stages. Once clinically presented, infected aneurysms are often at an advanced stage of development and associated with complicat...

A 75-year-old male with a history of alcoholic liver cirrhosis, sigmoid colon cancer, and metastatic liver cancer was admitted to our institution with a complaint of a prickly feeling in his chest. On admission, a chest radiograph revealed a normal cardio-thoracic ratio of 47%. Echocardiography revealed pericardial effusion and blood chemical analyses revealed elevated C-reactive protein levels...

A 73-year-old man underwent emergency endovascular abdominal aneurysm repair (EVAR) for a ruptured infected abdominal aortic aneurysm. Two years after EVAR, he was admitted with a spiking fever and left lower back pain. Computed tomography scan revealed not only recurrent graft infection with psoas abscess but also infection around the orifice of the superior mesenteric artery. Because conserva...

Colonoscopy, a relatively non-invasive procedure, has been associated with several complications including perforation, hemorrhage and abdominal pain. Post-colonoscopy bacteremia can occur up to 4.4% of the time but is almost always transient without significant clinical sequelae. Post-colonoscopy infective endocarditis, on the other hand, is a rare occurrence associated with high rates of mort...

OBJECTIVE To report a case and to review previous publications regarding the rare complication of aorto-enteric fistula following endovascular aortic aneurysm repair. METHODS We report the case of a stent-graft infection secondary to an aorto-enteric fistula 14 months after uncomplicated endovascular treatment of an infra-renal aortic aneurysm. RESULTS The surgical treatment involved the re...
