Factors Related to Blood Loss During Endoscopic Sinus Surgery.

Background: The safety and efficacy of endoscopic sinus surgery have improved with the development of new equipment and improved surgical techniques. However, it is accompanied by the risk of complications. Intraoperative blood loss is an important factor in the safe conduct of surgery.

The impact of surgical left atrial appendage amputation/ligation on stroke prevention in patients undergoing off-pump coronary artery bypass grafting.

Stroke is a major adverse event in patients developing atrial fibrillation (AF) after cardiac surgery. Surgical left atrial appendage amputation/ligation (LAA-A/L) during off-pump coronary artery bypass grafting (OPCAB) is routinely performed in our institution. We analyzed 578 consecutive patients (mean age 69 years, male 82%) undergoing OPCAB with or without concomitant LAA-A/L from 2011 to 2014 at our institution in a prospective observational manner.

Left Atrial Appendage Closure Reduces the Incidence of Postoperative Cerebrovascular Accident in Patients Undergoing Cardiac Surgery.

Background: Cerebrovascular accidents (CVA) are a major adverse event following cardiac surgery, for which atrial fibrillation (AF) is considered as a risk factor. We have recently performed left atrial appendage (LAA) surgical closure or amputation (LAAC/A), which is the main source of emboli, during open-heart surgery.

Methods and results: A prospective observational study of 1,831 consecutive patients (69.

Mid-term results for the Maze procedure in patients with non-mitral valvular atrial fibrillation.

Background: The Maze procedure in patients without mitral valve disease remains controversial, because of the increased invasiveness and operation time required to create additional incisions in the atria. The aim of this study was to assess prognosis following the Maze procedure in patients without mitral valve disease.

Methods And Results: One hundred and seven consecutive patients who underwent the Maze procedure between 2002 and 2008 was enrolled in this study.

Anomalous right subclavian artery with ascending aortic aneurysm: a case report.

We report a rare case of the ascending aortic aneurysm with an anomalous origin of the right subclavian artery. The right subclavian artery branched from the aorta as the fourth major vessel and ran behind the esophagus. Moreover, the left and right coronary arteries arose ectopically from the posterior and the left aortic sinus, respectively.
