Seven patients underwent surgical repair of the distal aortic arch aneurysm from January 1990 to October 1997. They were 5 men and 2 women ranging from 63 to 78 years of age (mean, 72.7 years). All patients were operated with a median sternotomy only. There was one operative death, which was ruptured case. However, there were no major complications in non-ruptured cases. This retrospective study suggests that it is possible to repair the distal aortic arch aneurysm through a median sternotomy approach alone, when 1) descending aorta originates with normal size just distal to sacciform aneurysm, 2) the maximum diameter of the aneurysm is over 70mm and 3) distal involvement of the aneurysm does not extend beyond the bifurcation of the trachea. It is useful to retract descending aorta proximally by three threads with pledget for distal anastomosis in inclusion technique.

Direct coronary artery reimplantation to the aorta and mitral valve repair were successfully performed in a 29-year-old female with Bland-White-Garland syndrome (BWG syndrome). Under cardiopulmonary bypass, the main pulmonary artery was completely transected and the left coronary artery was excised with a cuff of pulmonary artery wall. Then the left coronary artery was directly anastomosed to the ascending aorta. Mitral regurgitation was repaired with valvulo-annuloplasty. The post operative course was excellent.

The patient was a 52-year-old man with a history of antiphospholipid syndrome (APS), renal dysfunction and myasthenia gravis (MG). On May 2, 1998, he had sudden chest pain while sleeping. Enhanced computed tomography revealed acute aortic dissection (DeBakey type I). We performed emergency graft replacement of the ascending aorta and the aortic arch under extracorporeal circulation. Because of perioperative anuria, we used peritoneal dialysis (PD) just after the operation. Two days after the operation, we performed re-intubation nine hours after the extubation of the tracheal tube, and performed re-extubation three days later. For a while, his postoperative course was uneventful, but because of gradual worsening of APS, we administered more prednisolone, but 74 days after the operation, he died of multiple organ failure caused by an opportunistic infection, sepsis, and disseminated intravascular coagulation. This was very rare case of acute aortic dissection with MG and APS. After administration of more glucocorticoids, it is important to be wary of opportunistic infections.

Pulmonary artery (PA) rupture caused by a PA Swan-Ganz catheter is a rare complication but remains fatal in almost 50% of cases. False aneurysm of the PA is a rare presentation of PA rupture and should be considered as a possible diagnosis in a patient with a new lung mass after PA catheterization. We present a case of sudden-onset pulmonary alveolar hemorrhage during cardiovascular surgery due to a traumatic PA false aneurysm. The Swan-Ganz catheter might have been displaced by the thoracic aortic aneurysm with displacement of the catheter causing the false aneurysm and bleeding.

Objective: Whether or not emergent decompression/fusion surgery for paralysis caused by metastatic spinal tumors of unknown origin improves patient neurological outcome and survival remains unclear. This study aimed to evaluate the clinical outcomes of emergent decompression/fusion surgery for paralysis caused by spinal tumors of unknown or not previously diagnosed origin.Patients and Methods: Data from the medical records of 11 patients with spinal tumors of unknown origin (study group) were compared with those of 15 patients with metastatic spinal tumors of known origin (control group). The outcome measures were postoperative performance status, motor function evaluated with the Frankel grade, and actual survival after surgery as compared with the estimated survival calculated using the Tokuhashi score. χ2 analyses were performed to evaluate differences between the groups.Results: The mean performance status was 3.6 preoperatively, which improved to 2.9 postoperatively (P<0.05), in the unknown origin group and 3.6 preoperatively, which improved to 2.7 postoperatively (P<0.05), in the control group. Seven patients (64%) in the unknown origin group showed improvement in paralysis by ≥1 Frankel grade. By contrast, only 4 patients (27%) in the control group showed improvement in paralysis. The unknown origin group tended to show better improvement (P=0.05). All the patients in the unknown origin group underwent adjuvant therapy after definitive diagnosis following surgery. The unknown origin group showed a slight tendency toward better survival than toward the estimated survival.Conclusion: Emergent decompression/fusion surgery for patients with paralysis caused by metastatic tumors of unknown origin is potentially useful for diagnosing tumor origin and improving neurological outcomes and performance status, and thus for extending survival.
