The pseudoaneurysm was successfully managed by ligating the bleeding vessel. We should consider the possibility of pseudoaneurysm formation in a patient with gastrointestinal bleeding in the postoperative period following radical gastrectomy with regional lymph node and perivascular lymphatic dissection.展开更多

An 82-year-old man underwent endovascular aneurysm repair with a stent graft to exclude a 5.1-cm abdominal aortic aneurysm. Three months after the index procedure, the patient was taken to the emergency department at a medical university hospital. He presented with a 2-d history of bloody diarrhea. An endoluminal aortic stent graft infection was diagnosed, and an ADF was identified. The patient died of septic shock despite emergency surgery and intensive care. When encountered, stent graft infections require appropriate antibiotics and graft explantation.The diagnosis of an ADF is important, and surgery remains the most effective management if septic shock presents despite conservative treatment.展开更多

The lesion located in front of the head of the pancreas was found accidentally during a medical examination. The findings of computed tomography and positron emission tomography-computed tomography suggested a stromal tumor or malignant lymphoma. Surgical resection was performed. The lesions were patho- logically diagnosed as duodenal pseudolymphoma.展开更多

Following problems will be discussed: 1) The probability that the server is in a "generalized busy period" at time n; 2) The probability that the service station is in failure at time n, i.e., the transient unavailability of the service station, and the steady state unavailability of the service station; 3) The expected number of service station failures during the time interval (0, hi, and the steady state failure frequency of the service station; 4) The expected number of service station breakdowns in a server's "generalized busy period". Finally, the authors demonstrate that some common discrete-time queueing models with unreliable service station are special cases of the model discussed in this paper.展开更多
