11/435. Treatment of giant aortic aneurysm with tracheal compression and sternal erosion without circulatory arrest.

    Treatment of huge aneurysms involving the ascending aorta and the aortic arch with compression of the surrounding structures represents a surgical challenge. The case of a patient affected by respiratory insufficiency and sternal erosion caused by chronic giant aortic aneurysm is reported. The use of a stepwise approach and selective cerebral arterial perfusion ensured successful operative management, avoiding circulatory arrest and enabling an expeditious postoperative recovery.

12/435. Aortic dissection complicating cardiac surgery in a patient with calcified ascending aorta.

    Aortic dissection is a rare but devastating complication of cardiac surgery. Adequate and early diagnosis of intraoperative aortic dissection and quick therapeutic decision making are the keys for saving patients in such cases. We describe the case of a 68-year-old man referred for CABG and mitral valve replacement with severe calcification of the ascending aorta. Intra-operative transesophageal echocardiography was useful for diagnosis of intra-operative aortic dissection and malperfusion of the true lumen. Immediate switching of the arterial perfusion site established flow in the true lumen with prompt subsidence of the expanded false lumen. CABG, mitral valve replacement and graft replacement of the ascending aorta could be simultaneously performed in this patient.

13/435. Transient EDTA-dependent pseudothrombocytopenia in a patient with sepsis.

    Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia (EDTA-PTCP) is the phenomenon of a spurious low platelet count due to antiplatelet antibodies that cause platelet clumping in blood anticoagulated with EDTA. We describe a case of EDTA-PTCP that appeared transiently with the development of sepsis. A 50-year-old man underwent Bentall's aortic root replacement for acute aortic dissection with aortic insufficiency. Postoperatively the patient suffered paralytic ileus followed by methicillin-resistant staphylococcus aureus enteritis and septicemia with endotoxemia. EDTA-PTCP appeared with the development of sepsis, and disappeared with its resolution. To avoid incorrect diagnoses and inappropriate treatment, EDTA-PTCP should always be considered as a possible cause of reported low platelet counts, even in patients with sepsis.

14/435. Konno procedure for infective endocarditis involving aortic valve in a small child.

    The Konno procedure was performed to replace the aortic valve and the sinus of valsalva in a 1-year-old child with pneumococcal infective endocarditis. A Dacron (C.R. Bard, Haverhill, PA) graft and a 16 AP ATS Medical valve (ATS Medical Inc, Minneapolis, MN) were used. Adequate debridement could be easily performed. Postoperative recovery was uneventful. The procedure, originally developed for a narrow aortic annulus, could be a good option for the treatment of a small child with aortic valve endocarditis.

15/435. Coil embolization of a false aneurysm with aorto-cutaneous fistula after prosthetic graft replacement of the ascending aorta.

    AIM: To report palliative embolization of a false aneurysm over the distal suture line of an ascending aorta graft replacement. MATERIAL AND METHOD: A 78-year-old male patient was admitted for increasing bleeding of a chronic manubrium ulceration, 20 months after coronary artery bypass complicated by perioperative ascending aorta dissection requiring prosthetic graft replacement. One month later, he underwent epiploplasty for a mediastinitis followed by long-term antibiotic therapy. Five months later, he presented with a manubrium ulceration of the sternotomy. Spiral computerized tomography (CT) and aortography revealed a 20 mm anterior peri-prosthetic false aneurysm with a wide neck. Advanced age, active mediastinitis and patient's objection led us to perform percutaneous occlusion according to the Moret remodeling technique while protecting the coils release with balloon catheter inflation. RESULTS: No post-operative complication was observed and at 1-year follow-up the patient was doing well with no recurrent bleeding. magnetic resonance imaging (MRI) and spiral CT controls confirmed coils stability without any internal flow. CONCLUSION: Percutaneous coils embolization of a large false aneurysm in the ascending aorta can be a palliative treatment in a surgically unsuited patient.

16/435. A surgically treated case of Takayasu's arteritis complicated by aortic dissections localized in the ascending and abdominal aortae.

    Because complication by aortic dissection is markedly rare in patients with Takayasu's arteritis, a limited number of reports have been published regarding surgically treated cases of Takayasu's arteritis that is complicated by aortic dissection. When graft replacement of the ascending aorta and aortic arch and extra-anatomic bypass grafting were performed in a 72-year-old japanese woman with Takayasu's arteritis, which was complicated by aortic dissections localized in the ascending and abdominal aortae, the postoperative course of this patient was satisfactory. It was considered that the media became friable in this patient because of the presence of Takayasu's arteritis and that hypertension that persisted for a long time caused the independent development of aortic dissections in the ascending and abdominal aortae.

17/435. naloxone infusion and drainage of cerebrospinal fluid as adjuncts to postoperative care after repair of thoracoabdominal aneurysms.

    The mechanisms that produce paraplegia in patients after TAA repair are complex and involve alterations in regional blood flow to the spinal cord, CSF dynamics, and reperfusion. Although neither the minimal level of blood flow nor the maximal spinal cord pressure that can be tolerated by the spinal cord is known, adjuncts such as CSF drainage and naloxone infusions may allow longer durations of aortic cross-clamping before irreversible ischemia occurs. Because paraplegia is multifactorial and none of the recommended adjuncts alone provides complete protection of the spinal cord, a combination of treatments may be necessary to reduce the prevalence of neurological complications after thoracoabdominal aortic reconstruction. critical care nurses thus must be acquainted with the advanced monitoring techniques and the pathophysiology behind these new treatment modalities. Advanced assessment skills are also essential to recognize the potential neurological complications that may occur in these patients. Care of patients with TAA is a challenge. critical care nurses must use multidimensional skills in the areas of hemodynamic monitoring, physical assessment, and psychological counseling to effectively manage postoperative care of these patients.

18/435. Mycotic pseudoaneurysm of the aorta in children.

    Mycotic pseudoaneurysm of the aorta is a rare disease in childhood. We report on two cases which were diagnosed in an unselected general pediatric population within an 8-month period. The first case was a 16-month-old toddler with a normal cardiac history who presented with purulent pericarditis due to group A streptococcus and subsequent pseudoaneurysm formation of the ascending aorta while convalescing from varicella infection. The second case was a 14-year-old girl with a previously undiagnosed coarctation of the aorta who developed a Staphylococcus aureus aortitis in the dilated poststenotic segment with pseudoaneurysm formation and infiltration into the adjacent lung tissue. In both cases parenteral antibiotic therapy was administered over 10 and 4 days, respectively, followed by emergency surgery consisting of aneurysmectomy, coarctectomy (case 2), and in situ homograft implantation. Recovery was uneventful. In both cases early institution of a femorofemoral cardiopulmonary bypass prevented a fatal outcome despite intraoperative rupture of the pseudoaneurysm.

19/435. Aneurysm of the sinus of valsalva producing obstruction of the left main coronary artery.

    An aneurysm of the left sinus of valsalva compressed the left main coronary artery and the patient experienced anginal pain. Surgical correction consisted of obliteration of the orifice of the aneurysm, aortic valve replacement, and a saphenous vein bypass from the ascending aorta to the distal left anterior descending coronary artery. Postoperative studies revealed excellent function of the prosthetic valve, no recurrence of the aneurysm and retrograde filling of the left anterior descending and circumflex coronary arteries. Three years after the operation, the patient is asymptomatic.

20/435. Transmural necrosis of the esophagus secondary to acute aortic dissection.

    A case of transmural ischemic necrosis of the esophagus secondary to aortic dissection is presented. A 66-year-old woman with acute type A aortic dissection underwent total arch replacement with a technique of deep hypothermic arrest and retrograde cerebral perfusion. Postoperatively she had hematemesis, and endoscopic examination revealed circumferential mucosal necrosis and desquamation of the lower esophagus. She died of multiple organ failure on postoperative day 74. autopsy demonstrated transmural necrosis of the esophagus secondary to ischemia. ischemia of the esophagus secondary to aortic dissection is extremely rare.
