Ascending Aortic Pseudoaneurysm

Mycotic aneurysm of the aorta is a rare but highly fatal complication of coronary bypass surgery. A 49-year-old man developed mycotic pseudoaneurysm in the ascending aorta after coronary bypass in another hospital. Computed tomography showed the pseudoaneurysm originated from the previous aortic cannulation site. The defect was successfully repaired with pericardial-pledgeted sutures.

Abstract Background Pseudoaneurysm of ascending aorta is a rare but serious complication of cardiovascular surgeries and it infrequently occurs in the normal prosthetic graft materials. We share our experience with an unusual case of ascending aorta Dacron graft pseudoaneurysm caused by a fractured sternal wire. Case presentation A 34-year-old man, known case of Marfan syndrome, with history of two prior aortic surgeries for aneurysm of ascending aorta, arch and thoracoabdominal aorta, presented with hemoptysis. The hemoptysis originated from an aortobronchial fistula secondary to a huge ascending aorta Dacron graft pseudoaneurysm. The graft erosion and subsequent pseudoaneurysm was caused by a fractured sternal wire. Surgical repair of the pseudoaneurysm was performed successfully and a Gore-tex patch was placed behind the sternum over the graft to prevent further direct contact of the wire and the graft. Conclusion Sternal wires can damage the adjacent vascular grafts and lead to fatal complications such as pseudoaneurysm formation. Thus, preventive measures such as using sternal bands and placing a covering layer between the sternal wires and aortic grafts are recommended in patients with dilated or replaced ascending aorta.

Between 1984 and 1993, 20 patients underwent reoperation for the thoracic aorta or ascending aorta and aortic valve. There were 14 male and 6 female patients who ranged in age from 28 to 70 years with a mean of 53.2 years. The mean interval between initial operation and the 2nd operation was 70.4 months. Of the 20 patients, 6 had stigmata of Marfan's syndrome. The primary aortic pathology requiring initial operation was annuloaortic ectasia in 10 patients, aortic valvular disease in 5, aortic dissection in 3, and mega aorta syndrome, aortic aneurysm in multiple segments, or aortic arch aneurysm in 1 each. Cause of reoperation was pseudoaneurysm formation at suture lines in the ascending aorta in 6 patients, new or progressive dilatation in the remaining aortic segment in 5, new or persistent aortic dissection in 4, graft infection in 2, and recurrent aortic arch aneurysm in 1. The remaining 2 patients received a planned two-stage operation for multiple aneurysms or mega aorta syndrome. Six patients died early after reoperation, yielding a hospital mortality rate of 30%; however, 3 of the 6 deaths were related to a compromised preoperative clinical condition and 1 to perioperative contamination. Two operative deaths (10%) were related to operative techniques. Results suggest application of separate grafts for coronary artery reattachment, as in the Cabrol or Piehler techniques, or the aortic button technique for aortic root replacement, may help eliminate pseudoaneurysm formation, which is one of the major complications after operations on the ascending aorta. It is also suggested that early diagnosis and prompt operative treatment for recurrent or residual aneurysmal diseases of the aorta may be essential for successful definitive treatment.

Introduction: The aim of this study was to assess the relationships among cardiac output, extracorporeal blood flow, cannulation site, right (RCa) and left carotid (LCa), celiac (Ca) and renal artery (Ra) flows during extracorporeal circulation. Methods: A mock circulatory circuit was assembled, based on a compliant anatomical aortic model. The ascending aorta, right subclavian and femoral artery cannulations were created and flow was provided by a centrifugal pump (Cp); cardiac output was provided by a roller pump (Rp). Five volume flow rates were tested. The Rp was set at 4 L/min with no Cp flow (R4-C0) and the basic volume flow rates of the vessels were measured. The flow of the Cp was increased while the Rp flow was decreased for other measurements; R3-C1, R2-C2, R1-C3 and R0-C4. Measurements were repeated for all cannulation sites. Results: The RCa flow rate at R4-C0 was higher compared to the R3-C1, R2-C2, R1-C3 and R0-C4 RCa flows with subclavian cannulation. The RCa flow decreased as the Cp flow increased (p<0.05). The RCa flow with ascending aortic and femoral cannulation was higher compared to subclavian cannulation. Higher flows were obtained with subclavian cannulation in the LCa compared to the others (p<0.05). R4-C0 Ca and Ra flows were higher compared to other Ca and Ra flows with femoral cannulation. Ca and Ra flows decreased as Cp flow increased. Flows of the Ca and Ra with ascending and subclavian cannulations were not lower compared to the R4-C0 flow (p<0.05). Conclusion: This study shows that prolonged extracorporeal circulation may develop flow decrease and ischemia in cerebral and abdominal organs with both subclavian and femoral cannulations.

Mycotic Aneurysms

Purulent pericarditis is a rare disease in the era of antibiotics, with Streptococcus pyogenes being a possible, though uncommon etiology. Even more uncommon are mycotic aneurysms secondary to group A strep purulent pericarditis and bacteremia. We report a case of an 18-year-old female with a history of strep pharyngitis develop Streptococcus pyogenes purulent pericarditis with subsequent ventricular fibrillation (VF). Following initial stabilization, she ultimately developed a 4.8 cm mycotic aneurysm of the ascending aorta, with resultant compression of the pulmonary trunk and right pulmonary arteries.
