A chronic traumatic thoracic aortic aneurysm, 19 years after a traffic accident was successfully treated. A 34-year-old man was admitted because of chest discomfort. An upper GI examination was performed and an esophageal submembranous tumor was suspected. However, a chest CT examination showed a thoracic descending aortic aneurysm, the maximum size of which was 7.5cm×5.5cm. The final diagnosis was chronic traumatic thoracic aortic aneurysm. Generally most cases of chronic traumatic thoracic aortic aneurysm have no symptoms for a long time after an accident. However, some have reported that the development of an aneurysm is due to not receiving treatment. We performed graft replacement using the temporary bypass method because it was an easy technique and required less heparinization. Chronic thoracic aortic aneurysms have lower risk of bleeding during the operation than acute cases. For chronic cases which have stable hemodynamics, adjunctive methods (e. g., partial extracorporeal bypass, left ventricular bypass and temporary bypass) may facilitate a safe operation.

A 47-year-old man with over 10 years’ duration of ulcerative colitis treated by 5-aminosalicylic acid and intermittent topical steroids complained of acute epigastric pain. Esophagogastroduodenoscopy revealed diffuse mucosal edema with patchy redness, multiple erosions and nodularity of the stomach. Bioptic examination revealed marked eosinophilic infiltration, confirming the diagnosis of eosinophilic gastroenteritis. Systemic steroid therapy was initiated, whereas his ulcerative colitis and eosinophilia recurred when tapering the steroid. Addition of azathioprine was ineffective, and we subsequently started vedolizumab for eosinophilic gastroenteritis and ulcerative colitis. The medication effectively improved his abdominal symptoms and esophagogastroduodenoscopy and ileocolonoscopy 1 year later revealed endoscopic improvement of both diseases with histologically decreased level of eosinophilic infiltration. Considering that eosinophils also express α4β7 integrins, vedolizumab can be a possible therapeutic candidate for eosinophilic gastroenteritis as well as ulcerative colitis.
