A Case of Acute Renal Failure Following Abdominal Aortic Surgery / 日本心臓血管外科学会雑誌

A 75-year-old man received a diagnosis of an abdominal aneurysm and underwent abdominal aortic replacement. His left internal iliac artery was sacrificed because of the difficulty of reconstruction. Rhabdomyolysis of the left gluteus muscle resulted in acute renal failure (ARF) postoperatively. Continuous hemodiafiltration (CHDF) was performed from postoperative day (POD) 1 through POD 10 for the management of his ARF. During CHDF, the maximum value of serum creatinine was 5.10 mg/dl and it returned to the normal range of 1.10 mg/dl on POD 20. We conclude that the early deployment of CHDF was effective in rhabdomyolysis-induced ARF.

Postoperative Atrial Fibrillation Following Off-pump Coronary Artery Bypass Grafting / 日本心臓血管外科学会雑誌

It has been demonstrated that atrial fibrillation (AF) frequently occurs after coronary artery bypass grafting (CABG) and may cause cerebral infarction. The purpose of this research is to clarify the risk factors of AF in patients who underwent off-pump CABG (OPCABG). In this study, 142 patients (111 men and 31 women) were enrolled with an average age of 67 years old (range, 33-83). According to multivariate analysis, age and the preoperative peak early (E)/late (A) diastolic velocities ratio (E/A) were the independent predictors of postoperative AF. Patients who suffered from postoperative AF required a significantly longer hospital stay.

Treatment for Ischemic Heart Disease as a Comorbidity of Leriche Syndrome / 日本心臓血管外科学会雑誌

The aim of this study was to clarify the comorbidities of patients with Leriche syndrome and ischemic heart disease. We enrolled 26 patients with Leriche syndrome and who had undergone preoperative coronary angiography were enrolled. The comorbidities of diabetes, hypertension, and coronary artery disease developed in more than half of Leriche patients with Leriche syndrome. Marked coronary artery disease was diagnosed in 14 patients, 7 of whom underwent coronary artery bypass surgery. The Revascularization procedures performed in patients with Leriche syndrome were anatomical aortofemoral bypass in 15 and an extra-anatomical axillofemoral bypass in 9. In 2 cases of extra-anatomical bypass, occlusion developed in the long-term.
