OBJECTIVES The aim of this study was to evaluate the intraoperative fluorescence imaging (IFI) system in the real-time assessment of graft patency during off-pump coronary artery bypass graft. BACKGROUND Intraoperative fluorescence imaging is an intraoperative angiography-like imaging modality using fluorescent indocyanine green excited with laser light. Recently, assessment of graft patency ...

  Abstract   Background: Iatrogenic airway injury after endotracheal intubation and tracheotomy   remains a serious clinical problem. In this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   Methods: Since February 1995 th...

STATEMENT OF PROBLEM The most common method for parotid duct anastomosis is suturing. A ductal defect of greater than 1cm may prevent a direct anastomosis. PURPOSE The goal of this study was a sialographic evaluation to compare repairing a parotid duct with facial vein graft versus Gore-Tex tub in 19 dogs. MATERIAL AND METHODS Nineteen dogs were studied in this experimental trial. Extra ora...

Axial-flow ventricular assist devices (VADs) can be implanted either through a left thoracotomy with outflow-graft anastomosis to the descending thoracic aorta or through a midline sternotomy with anastomosis to the ascending aorta. Each method has advantages and disadvantages. Because these VADs produce nonpulsatile flow, their hemodynamic characteristics differ from those of pulsatile devices...

A 66-year-old man with a history of diabetes mellitus presented with angina pectoris with 3-vessel disease, and he underwent off-pump coronary artery bypass grafting via median sternotomy. After performing bypass grafting of the left internal thoracic artery to the left anterior descending artery, the appearance of anastomosis configuration appeared to be acceptable. However, transit time flow ...

OBJECTIVES Intraoperative transit time flow measurement (TTFM) is widely used to assess anastomotic quality in coronary artery bypass grafting (CABG). However, in sequential vein grafting, the flow characteristics collected by the conventional TTFM method are usually associated with total graft flow and might not accurately indicate the quality of every distal anastomosis in a sequential graft....

The following video, along with the in-depth perspective article published elsewhere in this issue, aims to take you through the significant steps and the theoretical aspects of aortic arch replacement using the “Branch-first” continuous perfusion technique (Video 1). In essence the procedure consists of 5 major steps: (I) Establishment of cardiopulmonary bypass using femoral inflow and moderat...

A patient with friable hepatic artery and poor hepatic arterial inflow, portal vein thrombosis and serious gastroesophageal varices underwent modified piggyback liver transplantation. The hepatic artery was reconstructed by interposing donor’s iliac arterial conduit anastomosed to the infrarenal aorta, while the portal vein flow was ensured by the interposition of donor’s iliac venous graft. Th...

Different suture techniques have been used for anastomosis in coronary artery bypass graft surgery. Bypass surgery may be difficult for patients who have small coronary arteries or marked size discrepancies between target coronary arteries and grafts. For proximal and distal anastomoses, three continuous stitches are first placed in the heel and toe of the small coronary arteries; for sequentia...

INTRODUCTION In renal transplantation, there is end-to-side anastomosis of renal artery to external iliac artery and end-to-end anastomosis of renal artery to internal iliac artery. The end-to-end internal iliac artery anastomosis can be associated with complications due to compromised distal vascular supply to limbs and penile erectile tissue. A method of end-to-side anastomosis can overcome t...
