Prevention of cerebral injury is an important consideration during repair of aortic arch aneurysm, and the major goal of cerebral protection techniques. We describe our surgical strategy for treatment of extended thoracic aortic aneurysms. Between January 2001 and June 2008, 17 men and 6 women, with a mean age of 67.9 +/- 8.3 years, underwent total replacement of the arch and descending aorta. Six (26.1%) patients required emergency surgery. A median sternotomy with a left anterolateral thoracotomy provided a good visual field, and bilateral axillary arteries were preferentially used for systemic as well as selective cerebral perfusion. Two (8.7%) patients died in hospital. Prolonged mechanical ventilation was required for 7.3 +/- 8.4 days after surgery in 17 patients who all recovered uneventfully. Permanent neurological dysfunction developed in 1 (4.3%) patient who died of sepsis 2 years after the operation. Our results suggest that total arch replacement through a median sternotomy plus a left anterolateral thoracotomy is helpful for extended replacement of the thoracic aorta as well as distal reoperation for dissecting type A aortic aneurysm. Perfusion via bilateral axillary arteries may improve cerebral protection.

Aortoesophageal fistula is a rare emergency that presents a real challenge for cardiothoracic surgeons. There have been few reports of survivors. We present the case of a 70-year-old man with aortoesophageal fistula, mediastinal abscess, and severe septicemia consequent to esophageal erosion and rupture of a chronic degenerative descending thoracic aortic aneurysm. The patient underwent successful surgical treatment by aorto-aortic bypass and bipolar esophageal exclusion in conjunction with a cervical esophagostomy and a feeding gastrostomy. The pleural cavity was copiously irrigated and drained. Three months later, a retrosternal gastric bypass operation was performed successfully. The patient's 6-month follow-up examination revealed no problems.

A 73-year-old man was admitted to the hospital due to severe hematemesis and collapse, severe anemia and inflammation. Two months ago, the patient had been treated with antibiotics due to septicemia with staphylococcus aureus. At that time CT scan had shown only thoracic arteriosclerosis. The subsequent high urgency upper endoscopy identified a circular mucosal defect in distal esophagus as bleeding origin. The patient died 10 hours after admission. Performing autopsy, a fistula between the thoracic aortic aneurysm and the distal esophagus was found in the background of severe arteriosclerosis. The rapid onset of an aneurysm with rupture after a bacterial infection is typical for a mycotic aneurysm.

We report a case of a 75-year-old man who had been complaining of fever and pelvic pain for 3 weeks. First angio-computed tomography (CT) characteristics and blood culture led to suspicion of a pneumococcal-infected aortic aneurysm, which however was not confirmed by the surgeon. The abdominal infectious aortitis caused by Streptococcus pneumoniae was affirmed by a second angio-CT performed 7 days later. Without further delay, the patient underwent surgery for resection of mycotic aneurysm and in situ reconstruction with aortobiiliac homograft, in association with antibiotics. He died 10 days after the surgery as a result of severe sepsis in a polyvalent intensive care unit. This case report highlights the severity of this pathology. We reviewed the relevant literature related to Streptococcal pneumoniae mycotic aneurysm located in the abdominal aorta, including 29 more cases. Various microorganisms have already been associated with mycotic aneurysms, including S pneumoniae. Infectious aortitis remains a rare disease. It is extremely important to establish an early diagnosis but it may be delayed because clinical manifestations are usually nonspecific. However, if left untreated it is always lethal. Antibiotic in combination with complete surgical excision of the infected aorta is the treatment of reference. This therapeutic association dramatically improved patient survival.

Streptococcus dysgalactiae subsp. equisimilis (SDSE) can cause recurrent bacteremic infection. We have characterized novel virulence properties of an SDSE isolate of type stG485.0 that caused severe sepsis three times in a patient despite that he had opsonizing antibodies to the isolate. An infected aortic aneurysm was suspected to be the focus for the persisting bacteria. For the first time we show that this SDSE isolate, as well as other invasive SDSE isolates, aggregate human platelets and efficiently internalize into human endothelial cells. These properties may aid SDSE to persist and could explain the tendency of SDSE to cause recurrent bacteremia.

Paramedics bring into the ED an elderly man who is complaining of right-sided chest and abdominal pain. Earlier this morning, a friend had arrived at the patient's home and found him on the floor at the bottom of the stairs. The patient is in pain, somewhat altered, and unable to provide further details about what happened. After numerous attempts, the paramedics were only able to place a 22-gauge peripheral line. On examination, his blood pressure is 98/55 mm Hg, heart rate is 118 beats per minute, respiratory rate is 32 breaths per minute, oxygen saturation is 94% on a nonrebreather, and temperature is 36.0 degrees C (96.8 degrees F). His Glasgow Coma Scale score is 12 (eyes 3, verbal 4, motor 5). Given the unclear events surrounding his presentation and the concern for trauma, the patient is boarded and collared. His chest is stable but tender, and because of noise in the resuscitation room, you have difficulty auscultating breath sounds. The abdominal examination is notable for marked tenderness over the right upper quadrant and right flank, with some guarding. There is also mild asymmetric swelling of his right lower extremity. The patient is critically ill, his history is limited, and at this point the differential is quite broad. You consider the possibility of a syncopal episode followed by a fall, with a closed head injury, blunt thoracic trauma, and blunt abdominal trauma. His hypotension could be secondary to hypovolemia (dehydration or blood loss due to a ruptured aortic aneurysm), heart failure (left- or right-sided dysfunction), cardiac tamponade, tension pneumothorax, or sepsis. Your ED recently purchased an ultrasound machine, you wonder whether bedside ultrasound can help narrow the differential and guide your resuscitation. You call over one of your new faculty members who just finished resident training; a fortunate decision for both you and the patient.

There are few case reports of cardiovascular surgery with multiple myeloma. We report 3 cases of cardiovascular surgery with multiple myeloma. CASE 1: A 73-year-old male hemodialytic patient with multiple myeloma was performed off-pump coronary artery bypass grafting (OPCAB) for angina. He was dead on the 72th postoperative day because of sepsis. CASE 2: A 68-year-old female patient with multiple myeloma was performed mitral valve replacement for mitral regurgitation. The postoperative course was uneventful. CASE 3: A 78-year-old male patient, the aorta was replaced with a artificial graft for impending rupture of thoracoabdominal aortic aneurysm. He was diagnosed with multiple myeloma after surgery. He was dead on the 99th postoperative day because of sepsis. One of the affecting prognosis factors is infection and it is intractable.

We report a case of successful in situ replacement with a superficial femoropopliteal vein panel graft for Dacron graft infection of the thoracic aorta. A 75-year-old man presented with septicemia and pseudoaneurysm caused by methicillin resistant staphylococcus aureus 2 years after Dacron graft replacement of the mid-descending aortic aneurysm. The patient underwent in situ replacement with a panel graft constructed of 3 deep vein panels after excision of the infected Dacron graft. The patient is free of infection and doing well over 2 years after surgery.

Arterio-enteric fistula is a rare, but potentially deadly cause of gastrointestinal bleeding. The disease occurs in two forms: primary as a result of atherosclerotic aortic aneurysm, aortitis, trauma, radiation, tumor invasion or penetrating ulcer, and secondary as a consequence of surgical aortal reconstruction. The clinical manifestation is mostly gastrointestinal bleeding, rarely back pain, fever and sepsis. Computed tomography with contrast medium is the most suitable diagnostic test, however, the diagnosis frequently requires explorative laparotomy. A case is presented of secondary arterio-enteric fistula, found two years after surgical treatment of chronic pancreatitis with pseudocystojejunostomy, which clinically manifested with gastrointestinal bleeding. Although there was strong suspicion of arterio-enteric fistula, the diagnosis was not verified by routine workup, but only on explorative laparotomy.

The generally accepted treatment for infected aortic aneurysms involves open surgical resection and debridement, with in situ or extra-anatomical bypass. Occasionally, endovascular management can be substituted for the standard operation dependent on the patient's condition. We report the case of an 81-year-old female with a ruptured infected aortic aneurysm and sepsis, successfully treated endovascularly. She had been on oral antibiotics for one year and is doing well 2 years after discharge.
