ABSTRACT
We describe our surgical experience of inflammatory abdominal aortic aneurysm (IAAA) in a 54-year-old man. Computed tomography (CT) with contrast enhancement revealed an infrarenal abdominal aortic aneurysm with marked thickening of the aneurysmal wall (mantle core sign) and left hydronephrosis. The left ureteral stenting was performed. Preoperative laboratory findings showed high levels of serum IgG4. The IAAA was removed and replaced with a woven-Dacron graft <i>in situ</i>. Histological examination revealed the IgG4 positive plasma cell, and demonstrated IAAA associated with IgG4. The postoperative serum IgG4 was reduced, but remained high. The postoperative CT revealed new right hydronephrosis, and the ureteral stent was performed. The mantle sign reduced in CT scan after steroid therapy. IAAA with hydronephrosis seems to be associated with IgG4-related sclerosing disease. In this case, the levels of serum IgG4 seems to be a good index for treatment efficacy.
ABSTRACT
A 70-year-old man presented at a nearby hospital with dysphagia, hematemesis, and hemorrhage. After examination by magnetic resonance imaging and gastrointestinal fiberscopy, he was referred to our hospital on the suspicion of an aortoesophageal fistula due to a thoracic aortic aneurysm. Considering the degree of invasion and infection, we planned two operations but were compelled to perform three operations because of esophageal leakage. Aortoesophageal fistula due to thoracic aneurysms are usually fatal, with only 18 reported survivors in the past 22 years. The optimal treatment for this condition is not yet known. We report survival of the first case of aortoesophageal fistula due to thoracic aneurysm complicated by mediastinitis caused by esophageal leakage in which management by two operations was initially planned. From this case many possible strategies to manage aortoesophageal fistula due to thoracic aneurysms arose. Therefore, we report this case together with a review of the literature.
ABSTRACT
Direct observation of the intravascular atherosclerotic change provides many diagnostic information and supports successful vascular surgery. Angioscopic inspections were performed in the 23 patients who underwent laser angioplasty for the peripheral arteries and 7 patients with aorto-coronary bypass surgery in this study. Useful images could be obtained in 19 (83%) of 23 observations in the peripheral arteries, and the successful rates of angioscopic observation were influenced by the diameter and the degree of kinking of each vessel. On the other hand, intraoperative observation of coronary artery with angioscope could be performed easily in all cases. From these findings, intraoperative application of angioscopy was considered to be useful procedure for the cardiovascular surgery.
