Case ReportsA case complicated with Horner's syndrome after off-pump coronary artery bypass.
In the present report, a case complicated with Horner's syndrome after off-pump coronary artery bypass (OPCAB) was presented. This case showed ptosis and miosis in the left eye promptly after OPCAB. No abnormal neurological findings other than Horner's syndrome were observed in postoperative examinations including head magnetic resonance imaging (MRI), and this case was thought to have Horner's syndrome as a complication after cardiac surgery through median sternotomy.

Case ReportsAbdominal aortic grafting for renal and lower extremity hypoperfusion due to aortic dissection with progressive thrombosis of a false channel.
We present the case of a 53-year-old man with renal and bilateral limb ischemia due to Stanford B aortic dissection. The thrombosis of the false lumen had progressed and compressed the true lumen, developing renal and leg ischemia. Urgent graft replacement of the infrarenal abdominal aorta with proximal fenestration was successfully performed and the patient was discharged without complications.

Case ReportsIsthmus of a horseshoe kidney overlying a ruptured abdominal aortic aneurysm: a case report.
Horseshoe kidney is a rare congenital anomaly showing various degrees of fusion and accessory blood supply. Coexistence of horseshoe kidney and aortic aneurysm therefore presents a technical challenge to vascular surgeons. ⋯ The aneurysm was exposed via a transperitoneal approach, and grafting was performed successfully together with division of the isthmus of the horseshoe kidney. Renal function showed no impairment postoperatively.

Comparative Study Controlled Clinical TrialMeasurement of cerebral-oxygenation status when commencing cardiopulmonary bypass in pediatric open-heart surgery.
We hypothesize that there is a difference in the cerebral-oxygenation status between cyanotic and non-cyanotic congenital heart disease when commencing a crystalloid-primed cardiopulmonary bypass (CPB). We tested this hypothesis by using near-infrared spectroscopy (NIRS). ⋯ NIRS revealed that the cerebral-oxygenated hemoglobin could be maintained at a similar level at the beginning of CPB in both groups. However, it showed a different distribution of cerebral-deoxygenated and total hemoglobin between the groups. An inadequate cerebral-oxygenation status may occur in the early phase of CPB in patients with cyanotic congenital heart diseases.

Comparative Study Clinical TrialFDG-PET imaging for lymph node staging and pathologic tumor response after neoadjuvant treatment of non-small cell lung cancer.
A number of studies have demonstrated that 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is effective for staging of lung cancer. However, the efficacy of FDG-PET for staging lung cancer after neoadjuvant treatment is still controversial. This study compared FDG-PET and computed tomography (CT) for lung cancer staging, and evaluated the ability of the two methods to predict the pathologic response of the primary tumor to neoadjuvant treatment. ⋯ FDG-PET did not appear to offer any advantages over CT for lymph node staging or for predicting the pathologic response after neoadjuvant treatment of non-small cell lung cancer.
