In thoracic endovascular aneurysm repair (TEVAR), the common femoral artery is typically used as the standard vascular access. However, in some cases, alternative vascular accesses must be considered, or endovascular treatment may need to be abandoned due to vascular diameter or characteristics. A female in her 70 s presented with saccular aortic aneurysms located at the distal arch and descending aorta, possibly secondary to bacteremia. She had a history of partial arch replacement and ascending aorto-bi-iliac artery bypass for ascending aortic aneurysm, as well as calcified abdominal aortic stenosis, performed five years prior. In this case, we successfully treated the aneurysms with antegrade TEVAR, accessing through the extra-anatomical bypass graft, which was exposed in the epigastric preperitoneal space. This is the first case report of TEVAR using access from an extra-anatomical bypass graft connecting the ascending aorta to the lower extremity.

Introduction: Relieving cancer pain in children poses significant challenges, especially when pharmacological therapies become ineffective or difficult to administer. This case report describes a pediatric patient with renal cancer who experienced severe lumbago and was successfully treated with implanted epidural analgesia. Case: An 11-year-old boy had been diagnosed with left renal cell carcinoma 1 year prior. After a left nephrectomy and postoperative chemotherapy, the patient experienced a local recurrence a few months later. The patient was referred to the palliative care team because of discomfort in the lumbar region. Detailed imaging and medical history strongly suggested cancer-related pain. Opioid therapy was initiated; however, the patient developed increasing difficulties with oral intake due to headache and nausea associated with escalating pain levels. Epidural analgesia was administered, which resulted in pain relief and improved oral intake. Considering the child’s prognosis, a subcutaneous implantable epidural port was placed to facilitate the continuation of treatment. Subsequently, the patient’s quality of life improved, allowing for activities such as outings. Conclusion: When facing the limitations of pharmacological therapies, a nerve block such as an epidural analgesic can be an effective therapeutic option in pediatric cancer treatment.

A 65-year-old man who had been taking warfarin for a mitral mechanical valve, was transported to our hospital for acute heart failure 3 months after switching to edoxaban. The fluoroscopy revealed restriction of the mechanical valve opening, and the catheterization showed an increased pressure gradient of the mechanical valve. The patient was diagnosed with valve thrombosis, and emergency redo mitral valve replacement was performed. The patient recovered well without complication. In cases with mechanical heart valves, sufficient explanation and education about warfarin administration is mandatory for patients' home doctors as well as patients and their families.

BACKGROUND: In health examinations for local inhabitants in cadmium-polluted areas, only healthy people are investigated, suggesting that patients with severe cadmium nephropathy or itai-itai disease may be overlooked. Therefore, we performed hospital-based screening to detect patients with cadmium nephropathy in two core medical institutes in cadmium-polluted areas in Akita prefecture, Japan. METHODS: Subjects for this screening were selected from patients aged 60 years or older with elevated serum creatinine levels and no definite renal diseases. We enrolled 35 subjects from a hospital in Odate city and 22 from a clinic in Kosaka town. Urinary ß-microglobulin and blood and urinary cadmium levels were measured. RESULTS: The criteria for renal tubular dysfunction and the over-accumulation of cadmium were set as a urinary ß-microglobulin level higher than 10,000 μg/g cr. and a blood cadmium level higher than 6 μg/L or urinary cadmium level higher than 10 μg/g cr., respectively. Subjects who fulfilled both criteria were diagnosed with cadmium nephropathy. Six out of 57 patients (10.5% of all subjects) had cadmium nephropathy. CONCLUSIONS: This hospital-based screening is a very effective strategy for detecting patients with cadmium nephropathy in cadmium-polluted areas, playing a complementary role in health examinations for local inhabitants.

A diagnosis of active aortic valve endocarditis was made in a 52-year-old man who presented with fever and edema. Blood cultures were positive for Streptococcus gallolyticus subsp. pasteurianus. The infection was treated successfully using antibiotics and dental care, but a mobile vegetation-like structure on the aortic valve and severe aortic regurgitation, mainly due to aortic annulus dilatation, remained and required surgery. During the surgical procedure, the aortic valve leaflets were seen to be almost normal, and the regurgitation was found to be mainly due to aortic annulus dilation. Regurgitation could be managed with external suture annuloplasty alone, although a second session was necessary to reduce the annular size by one size. The annular size has been stable for over 1 year after surgery without re-operation of the aortic valve. This procedure not only reduces the operation time but also decreases the surgical stress and avoids the need for prosthetic valve replacement.

Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly. Although asymptomatic in most cases, with the anomaly only being detected incidentally, surgical correction should be considered before onset of severe myocardial ischemia in such cases. Here, we present a 70-year-old man who was referred to our department due to chest pain on effort and was given a diagnosis of ARCAPA concomitant with mild aortic stenosis. As the symptoms and the degree of aortic stenosis deteriorated during follow-up, the patient underwent direct re-implantation of the right coronary artery into the ascending aorta and aortic valve replacement. The patient's postoperative course was uneventful, and the symptoms disappeared. Postoperative myocardial perfusion scintigraphy revealed improvement of the myocardial ischemic area.

OBJECTIVE: Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined. Correlations between MMR-related protein expression and clinicopathological factors of endometrial cancers are analyzed in the present study. METHODS: A total of 191 endometrial cancer tissues treated between 1990 and 2007 in our hospital were enrolled. Immunoreactions for MSH2, MLH1, MSH6, and PMS2 on tissue microarray specimens and clinicopathological features were analyzed retrospectively. RESULTS: Seventy-six cases (40%) had at least one immunohistochemical alteration in MMR proteins (MMR-deficient group). There were statistically significant differences of histology, International Federation of Gynecology and Obstetrics (FIGO) stage, and histological grade between MMR-deficient group and the other cases (MMR-retained group). Response rate of first-line chemotherapy in evaluable cases was slightly higher in MMR-deficient cases (67% vs. 44%, p=0.34). MMR-deficient cases had significantly better progression-free and overall survival (OS) compared with MMR-retained cases. Multivariate analysis revealed MMR status was an independent prognostic factor for OS in endometrial cancers. CONCLUSION: MMR-related proteins expression was identified as an independent prognostic factor for OS, suggesting that MMR was a key biomarker for further investigations of endometrial cancers.

OBJECTIVE: Compared with serous adenocarcinoma (SAC), clear cell carcinoma (CCC) often shows chemo-resistance, which would potentially lead to a poor prognosis. On the other hand, there have been arguments over prognoses of CCC and SAC disease. In the present study, multivariate analysis to compare prognosis of CCC patients with that of SAC was aimed for the patients selected from central pathologic review. METHODS: Between 1984 and 2009, a total of 500 ovarian cancer patients were treated at our university hospital. Among them, 111 patients with CCC and 199 patients with SAC were identified through central pathological review. Overall survival and progression-free survival were compared using Kaplan-Meier method, and prognostic factors were investigated by multiple regression analyses. RESULTS: Median age was 52 years for CCC and 55 years for SAC (p=0.03). The ratio of stage I patients were significantly higher in CCC compared with SAC (55% vs. 13%, p<0.01). Among evaluable cases, response rate was significantly lower in CCC than that in SAC (32% vs. 78%, p<0.01). No significant differences of progression-free survival and overall survival were observed in stage I patients; however, prognoses of CCC were significantly poorer than those of SAC in advanced-stage disease. In stage II-IV patients, not only residual tumors and clinical stages, but also clear cell histology were identified as predictors for poor prognosis. CONCLUSION: Clear cell histology was identified as a prognostic factor for advanced-stage ovarian cancers. Histologic subtypes should be considered in further clinical studies, especially for advanced epithelial ovarian cancers.

In this study, we report early and mid-term outcomes of endoscopic saphenous vein (SV) harvesting (EVH) for coronary artery bypass grafting. EVH is expected to have superior cosmetic results and fewer wound complications than conventional open techniques. EVH was performed in 262 patients from April 2008 to December 2010. From September 2010, we have administered heparin before EVH to prevent intraluminal SV clot formation. The mean age of the patients was 70±7.3 years, and 178 (67.9%) patients were men. The success rate of EVH was 97.3%. Hospital mortality was 1.2%. Postoperative wound complications occurred in only 7 (2.8%) patients. The early and mid-term patency was 95.8% (276/288) and 74.2% (187/252), respectively, as evaluated by postoperative angiography or computed tomography. Comparing the mid-term patency rate between the groups with or without systemic heparinization before EVH, statistical significance was not observed, but the mid-term patency was good in the group with systemic heparinization (82.5% vs. 73.6%, p=0.16). Actuarial 1-year and 3-year survival were 93.9% and 79%. Actuarial 1-year and 3-year major adverse cardiac event-free rates were 92.2% and 77.5%. In 10 patients who had SV graft occlusion during the observation period, percutaneous coronary intervention was required for the native coronary artery. EVH has great cosmetic advantages and has a good early patency. However, the mid-term patency is not satisfactory. Thus, systemic heparinization before EVH, improvement of the device and further clinical experience and techniques are required to improve the mid-term and late patency.

A 47-year-old man was referred to our hospital with acute congestive heart failure. Echocardiography and computed tomography revealed a left atrial tumor obstructing blood flow. An emergency operation was performed to relieve the obstruction. The tumor deeply invaded the posterior wall of the left atrium. We did not completely resect the tumor. The patient was discharged 10 days after surgery without complications. The tumor was diagnosed as pleomorphic rhabdomyosarcoma histopathologically. Adjuvant chemotherapy (cyclophosphamide, vincristine, adriamycin and dacarbazine) was started 23 days after surgery. Although partial remission was achieved, the tumor started to grow after chemotherapy was discontinued because of severe adverse effects. The patient died 11 months after surgery. In this patient, even though complete resection was not done, emergency palliative surgery was effective to treat acute heart failure and to establish a pathologic diagnosis of the tumor. We report this rare case and discuss the therapeutic strategy for primary cardiac sarcomas.
