We performed surgical repair of a giant left coronary ostial aneurysm after aortic root replacement using composite valve graft (modified Bentall procedure) in a patient with Marfan syndrome. Aneurysmal formation in the left main stem itself is very rare. In order to avoid mobilizing the coronary ostium from severe adhesions after previous surgery and to reduce the tension on the anastomosis, t...

Gastric and colon interposition are the commonly used in esophageal operations. In this report, Two jejunal esophageal interposition cases are presented. In the first patient, a free jejunal interposition graft was used to re-establish swallowing route in a patient who suffered severe esophageal and gastric chemical burn, and failure of colon interposition graft. The second patient had a leak o...

An 83-year-old man with aortic arch aneurysm underwent zone 0 thoracic endovascular aortic repair (TEVAR) by the chimney graft technique with two supra-aortic arch debranching grafts and developed subacute type A ascending aortic dissection. We performed emergency open conversion with circulatory arrest under deep hypothermia. The tip of the chimney graft (around the sino-tubular junction in th...

Dual graft liver transplantation has been demonstrated to be feasible as well as effective in increasing the donor pool and in preventing the potential for small-for-size syndrome. However, little is known about the pathophysiological and immune processes following dual graft liver transplantation due to the lack of appropriate animal models. The aim of this study, therefore, was to establish a...

OBJECTIVE During coronary surgery, proximal vein graft anastomoses have been performed by using an aortic partial occlusion clamp to allow for a hand-sewn anastomosis. The purpose of this multicenter, prospective, randomized trial was to evaluate the efficacy of the PAS-Port device (Cardica, Inc, Redwood City, Calif), which allows an automated proximal anastomosis to be performed without aortic...

AIM Pseudoaneurysm (PA) at the anastomosis site in kidney transplantation is a rare but serious complication that usually requires graft nephrectomy. Literature reports are sporadic and usually focused on limb rather than graft salvage. In this paper we focus on this last point. MATERIAL OF STUDY 6 patients presenting large PA at the anastomosis between iliac and graft artery were identified ...

OBJECTIVES We report a comprehensive assessment and validation of a new intraoperative angiography technique. BACKGROUND Technical problems at the site of the distal anastomosis compromise an underappreciated proportion of coronary bypass grafts. The absence of a systematic, validated technique to verify graft patency in the operating room represents a significant breach in quality assurance....

OBJECTIVES Mucosal free grafts may be successfully applied in many surgical interventions. This study aims at investigating the feasibility of palatal mucosa graft in sub-glottic field in an animal model. METHODS This randomized prospective controlled study was conducted with an animal model. Sub-glottic inflammation was created in 15 adult rabbits in each group and sub-glottic stenosis surge...

BACKGROUND We investigated in a porcine model whether measuring both the flow distal to an anastomosis and the graft transit time flow (TTF) gives a more accurate picture of the true blood flow in the left anterior descending artery (LAD) than graft TTF measurement alone. METHODS We performed off-pump coronary artery bypass grafting (CABG)-left internal mammary artery (LIMA) to the LAD-on 5 Y...

A 23 year-old-female patient with a history of renal transplantation at the left iliac fossa 12 years ago underwent a recent renal transplantation to the right side, one month prior to our evaluation. The graft is carrying an ureteropelvic duplication with 2 ureterovesical anastomosis described by pelvic ultrasound. In the early postoperative course, a technetium-99m mercaptoacetylglycine-3 (Tc...
