The results of complete graft replacement for thoracoabdominal aortic aneurysm remains unsatisfactory. The operative strategies, including the method of reconstruction of visceral vessels and the protection of abdominal organs and spinal cord, are controversial. Two male patients (53 and 59 years of age) had thoracoabdominal aortic aneurysms including the celiac artery and small abdominal aortic aneurysm in the renal arterial part. They underwent replacement of a large aneurysm using a Dacron prosthesis with reconstruction of the celiac artery. The remaining small aneurysm was wrapped by a bandage of Teflon tape 3mm in width. This wrapping technique was easy to perform and could be sufficiently adapted to the aneurysm preserving visceral arterial branches. The postoperative courses were uneventful. Their postoperative enhanced CTs (41 months and 26 months after surgery, respectively) revealed no enlargement of the wrapped aortic aneurysm and no stenosis of the visceral branches. This result suggests that our wrapping method is useful to reinforce the wall of small aortic aneurysms.

Mandibular cortical erosion detected on dental panoramic radiographs is associated with increased risk of osteoporosis in older adults. Additionally, many reports have demonstrated an association between decreased number of teeth present and osteoporosis. However, whether mandibular cortical erosion is associated with a decreased number of teeth remains unclear. The purpose of this study, therefore, was to clarify the association between mandibular cortical erosion and number of teeth present in Japanese men and women aged 40 years and older. Among patients who visited our university hospital and underwent dental panoramic radiography for the diagnosis of dental diseases, 839 patients (293 men and 546 women) aged 40–89 years (mean [SD], 63.7 [10.6] years) participated in this study. Multiple regression analysis revealed that mildly to moderately eroded cortex (p = 0.007) and severe eroded cortex (p < 0.001) were significantly associated with a decreased number of teeth present. Analysis of covariance adjusted for covariates revealed a significant association between mandibular cortical erosion category and number of teeth present (p < 0.001). Subjects with a severely eroded cortex had significantly fewer teeth present than those with a normal cortex (mean [SE], 20.7 [0.5] vs. 23.4 [0.3], p < 0.001) or mildly to moderately eroded cortex (22.2 [0.4], p = 0.04). Subjects with a mildly to moderately eroded cortex had significantly fewer teeth present than those with a normal cortex (p = 0.033). Our results suggest the significant association between mandibular cortical erosion and number of teeth present in Japanese men and women aged 40 years and older.
