Gastrointestinal bleeding caused by peptic ulcer or portal hypertension is a serious complication in liver transplant recipients. However, Gastrointestinal bleeding from hepatic artery origin after liver transplantation is rare. We report duodenal massive bleeding secondary to erosion of hepatic artery after liver transplantation in two patients. This was diagnosed by angiography and treated su...

Acute aortic type A dissection is a life-threatening disease that requires immediate surgical intervention. When dissection occurs during pregnancy, it is of high risk for both the mother and the fetus. In this study, we reported two cases of acute aortic dissection in late pregnancy at 28 weeks and 32 weeks of gestation respectively. After the two patients underwent a cesarean section and deli...

The occurrence of graft rejection and/or graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is largely depended on whether the re‐ cipient and the donor have matched HLA types. Under normal circumstances, the individu‐ al with completely matched HLA antigens can be the donor. However, due to the high level of HLA polymorphism, the major obstacl...

Mechanical circulatory support has been used to treat graft failure after heart transplantation, but in patients who needed mechanical circulatory support because of chronic rejection, we have suffered from the treatment because its outcome was catastrophic. Multiple organ failure was often caused by the addition of or increase in immunosuppressive medications, and it is known as a cause of the...

Aortic endograft infolding is considered a rare endograft related complication and is mostly reported after deployment in the thoracic aorta. We report a case of early abdominal endograft infolding with luminal obliteration and acute bilateral limb ischemia after endovascular treatment of a common iliac aneurysm. Even though completion Computed Tomography (CT) angiography, three days prior, rev...

It is thirty-five years since the initial coronary artery bypass graft (CABG) was performed in Japan in 1970. There was more risk in surgery in the early days, and many efforts have been made to decrease the mortality rate. Since the 1980’s when I was training to be a heart surgeon, surgical outcomes have improved, and the number of surgical cases has been steadily increasing. Since the long-te...

BACKGROUND The left internal mammary artery (LIMA) is the choice for grafting of the left anterior descending coronary artery (LAD). One possible mechanism of the rare graft failure involve the presence of competitive flow. METHOD 105 patients who had undergone coronary bypass grafting between 1998 and 2000 were included in this observational study. The recatheterizations were performed 28 mo...

The purpose of this study was to histometrically evaluate an absorbable collagen membrane (Bio-Gide) and a nonabsorbable polytetrafluoroethylene membrane (PTFE), associated with or without bone grafts, regarding "re-osseointegration" after treating ligature-induced peri-implantitis defects in dogs. All mandibular premolars were removed from five 2-year-old mongrel dogs. After 3 months of healin...
