Single-Stage Total Arch Replacement With Open Stent Graft for Kommerell's Diverticulum With Right-Sided Aortic Arch.

We treated a 70-year-old patient with Kommerell's diverticulum associated with an aberrant left subclavian artery and right aortic arch using single-stage total arch replacement with a commercially available open stent graft through only a median sternotomy. A four-branched prosthetic graft was implanted after insertion of the open stent graft through the anastomotic site under moderate hypothermia and cardiopulmonary bypass with selective cerebral perfusion. The aberrant subclavian artery was occluded by coil embolization from the distal site and anatomically reconstructed from the prosthetic graft.

Successful surgical resection of giant arteriovenous malformation in supraclavicular fossa.

A 42-year-old woman with a large congenital giant arteriovenous malformation in the left supraclavicular fossa underwent surgical resection. Although endovascular treatment was initially planned, it was impossible to occlude the multiple feeding arteries (transverse cervical, clavicular branch of left internal mammary, thoracoacromial, anterior/posterior circumflex humeral), and the anatomy was difficult. After removal of the left clavicle, the arteriovenous malformation was exposed.

[Postoperative Atrial Fibrillation in Patients who Underwent Thoracic Aortic Surgery].

Purpose: Postoperative atrial fibrillation (POAF) is a very common and important complication occurring after open heart surgery. Risk factors and prevention measure including β blocker use have been reported mainly in regard to patients who underwent coronary artery bypass grafting, while little is known about POAF following thoracic aortic surgery. In the present study, we examined risk factors related to POAF and effective prevention of POAF in patients who underwent thoracic aortic surgery.

Atrial fibrillation following aortic valve replacement: impact of perioperative use of intravenous β-blocker.

Objectives: Despite recent advances in perioperative management, postoperative atrial fibrillation/flutter (POAF) remains the most common complication after cardiac surgery. Therefore, it is important to determine related risk factors to establish effective management. However, most studies have focused on patients undergoing coronary artery bypass grafting and little is known about POAF in those who receive aortic valve replacement (AVR).

The efficacy of tolvaptan in the perioperative management of chronic kidney disease patients undergoing open-heart surgery.

Purpose: The perioperative management of chronic kidney disease (CKD) patients undergoing open-heart surgery is challenging. In this study, we evaluated the effects of tolvaptan in CKD patients after open-heart surgery.

Methods: Between 2010 to 2015, 731 patients underwent open-heart surgery in our hospital.

Open Surgical Repair Can Be One Option for the Treatment of Persistent Type II Endoleak after EVAR.

Purposes: Endovascular abdominal aortic aneurysm repair (EVAR) is an increasingly used method of repairing abdominal aortic aneurysm (AAA). However, the treatment of persistent type II endoleak is still a controversial issue. Five cases are reported here in which we performed open surgical repair of growing aneurysm due to persistent type II endoleak.
