Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and p...

In order to overcome the problems of suture method in vessel anastomosis, many non-suture methods have been designed; however, they still have their limits and drawbacks in limited in smaller vascular and destruction on vessel wall. The purpose of this study is to investigate the direct sutureless end-to-end anastomosis by using stent graft. An ex-vivo experiment was conducted to evaluate the o...

Methods We measured intraoperative grafts flowmetry in three patients with important retrograde flow from the coronary arteries throught saphenous vein grafts, verified after distal anastomosis. The surgeries were performed off pump. After the revascularization was completed, in the intraoperative model, we partially clamped the aorta, including both proximal veins anastomosis, and measured the...

end of the stent graft is extracted from the aorta. If another graft is used, proximal anastomosis is carried out with the balloon inflated. To complete the anastomosis a second Foley catheter is passed through a limb of the new graft (Fig 2). While the original catheter is deflated and removed, the second balloon is inflated in the suprarenal aorta (Fig 3) and the anastomosis completed. ACKNOW...

Vascular access dysfunction is a major source of morbidity for end-stage renal disease patients on hemodialysis. The arteriovenous graft is a common access type for many of these patients. Frequent stenosis formation and thrombosis complicate this form of access. Patients may have a rapidly forming and recurrent venous stenosis at the graft-vein anastomosis that has been seen in both animal mod...

OBJECTIVE In redo coronary artery bypass grafting (CABG), repeat median sternotomy is a routine approach when the graft to the left anterior descending artery (LAD) is occluded. However, it is important to avoid injury to the patent graft to LAD during repeat sternotomy. We retrospectively reviewed our cases to assess our combined strategy for a safer redo CABG. METHODS The study group compri...

A 74-year-old woman underwent replacement of the ascending aorta for acute type A aortic dissection. The patient suffered from bacteremia postoperatively and repeated computed tomography showed an increasing diameter of pseudoaneurysms at the site of the proximal anastomosis due to graft infection. Re-mechanical Bentall operation and arch replacement were therefore performed using a composite g...

The vascular anastomosis free of suture was made by using an absorbable suture and its tensile strength was compared with that of non-absorbable suture anastomosis. 29 adult mongrel dogs weighing 7.5 to 13.5 kg were used. Two kinds of vascular anastomosis were performed, that is, artery-to-artery anastomosis and vascular prosthetic graft to artery anastomosis. They were made in the right caroti...

Introduction Biosynthetic prosthesis has become the trend to carry out arterial reconstruction in infected sites since considered to be resistant to infection. Late graft occlusion is the only complication reported in literature so far. We report a case of biosynthetic graft infection which led to early detachment of the femoral anastomosis of a femoral-popliteal above-knee bypass. Material A...
