This paper reports on a case in which a heavily-calcified so-called “porcelain aorta” (including the ductus arteriosus) was observed, together with a patent ductus arteriosus and aortic stenosis associated with a bicuspid aortic valve. A 76-year-old man had been referred to our hospital on a diagnosis of aortic stenosis. Since angiography revealed slight contrast in an area on the right side of the heart, echocardiography was performed and revealed patent ductus arteriosus. Severe circumferential calcification of the ascending aorta and aortic arch was observed on CT scans. Almost no calcification was observed in other areas. Aortic valve replacement and closure of the ductus arteriosus (transpulmonary approach) were performed by means of a balloon to temporarily occlude the aorta, as surgical clamping was impossible due to calcification. Hypothermic systemic perfusion and antegrade selective cerebral perfusion were used. The postoperative progress of the patient was good. Bicuspid aortic valve and patent ductus arteriosus are highly likely to be present in combination in cases of congenital cardiac anomaly, and it is therefore necessary to be particularly attentive when diagnosing such cases. It was considered that our patient, an adult suffering patent ductus arteriosus, was a rare case in which the calcified ductus arteriosus was observed and the calcification had spread to the ascending aorta.

Introduction: This report describes a case of hyperactive delirium induced by tapenatadol whose symptoms were successfully managed with opioid-switching to oxycodon. Case: A 67-year-old female, who had been treated with chemotherapy for malignant thymoma, had to stop chemotherapy because of her carcinomatous pericarditis. Tapentadol 200 mg per day was administrated for her unbearable chest wall tumor invasion-related somatic pain. After a while, insomnia, visual hallucination, thought disturbance, and attention disturbance were appeared. We diagnosed as hyperactive delirium. Because her somatic pain was favorably controlled by tapentadol, we additionally administered quetiapine 50 mg per day instead of replacing tapentadol. Unfortunately, quetiapine was not effective for the delirium. We therefore switched opioids from tapentadol to oxycodon. The delirium was remitted soon after the switching without relapsing of the pain. Conclusion: Tapentadaol reportedly induce hyperactive delirium via its noradrenaline reuptake inhibitory action. This case suggests that switching tapenatadol to other opioid could be an effective option for opioid induced delirium.

We performed endovascular stent-graft placement on 39 patients with abdominal aortic aneurysms between 1996 and March 2002-a period of approximately 5 years (first half: until the end of June 1998, second half: July 1998 onward). Three patients in the first half of the period and 8 patients in the second half were 80 years or older. Two cases of mycotic aneurysm were observed. During the second half, we encountered high-risk cases in which the patients had complications such as coronary artery disease (5 patients), COPD (1 patient) and thoracic aortic aneurysm (4 patients). Although we had to switch to surgery in 3 patients during the first half of the period, we successfully placed stent-grafts in the other 36 cases (92%). Endoleaks were observed in 6 patients, and dissection of the iliac artery was observed in 5 patients (stents had been placed in all patients). In 50% of all cases in the first half of the period and 89% of all cases in the second half, stent-graft placement was successful and no endoleak was observed. During the follow-up period, 3 cases required additional treatment, and another 4 cases required surgery. Four patients died in hospital during the first half of the period, and 3 patients died during the following 3 years. The 3-year survival rate was 82%. It was considered that stent-graft placement for abdominal aortic aneurysms is particularly effective for high-risk patients, and that the results of this type of therapy will improve in the future.

We performed gamma knife treatment for multiple brain metastases including a left frontal lobe lesion in a patient in his 60s who had renal cell carcinoma. After treatment, the left frontal lobe lesion initially shrank but then began to grow again, resulting in extensive edema, right hemiparesis, impaired activities of daily living (ADL), and decreased motivation. Although the renal cell carcinoma was in the terminal stage, we judged that recovery of ADL could be expected by removing the left frontal lobe lesion and therefore performed craniotomy tumor removal. As a result, the patient’s motivation and right hemiplegia markedly improved and ADL dramatically improved. Although the period from craniotomy tumor removal to death was as short as 2 months, significant improvement of ADL during this time was achieved by removing the tumor. Tumor resection for metastatic brain tumors is rarely performed in the setting of end-stage cancer. However, this case highlights the potential of brain tumor resection as palliative treatment that can be considered for improving ADL even in patients with terminal cancer.
