A 64-year-old man was admitted with intermittent high fever of 4 months duration and with three episodes of arterial embolism in the previous 2 months. Several investigations revealed evidence that those episodes involving bilateral popliteal arteries and the left external iliac artery originated from mycotic emboli. Severe mitral insufficiency due to infective endocarditis was also recognized. The ischemic symptoms improved after medical treatment. Despite antibiotic therapy for 4 weeks, inflammatory signs did not subside. Since aneurysm formation of the left external iliac artery at the embolized portion was detected on CT, mitral valve replacement and aneurysmectomy with femoro-femoral grafting were done concomitantly. Inflammatory signs disappeared immediately after the operation. Pathological findings indicated organization of the mitral vegetation and evidence of active infection in the aneurysm wall. Though aneurysmal change of a symptomatic embolized site is not common, the preoperative evaluation of possible associated mycotic aneurysm is important to decide on surgical strategy for infective endocarditis complicated by embolism.

A 57-year-old man suffered hemoptysis during an examination for gastric carcinoma. Enhanced computed tomography demonstrated rupture of a thoracic aortic aneurysm to the left pulmonary lower lobe. The lateral segment of the liver was atrophic due to intrahepatic cholelithiasis. Emergency operation was performed after he was transferred to our hospital. The thoracic aorta was reconstructed using a temporary bypass and the pulmonary left lower lobe was resected. The omentum was mobilized and used to cover the prosthesis and bronchial stump. The gastric carcinoma and intrahepatic cholelithiasis with biliary stones in the common bile duct were treated in the next procedure. The pathologic examination revealed lymph node metastasis; thus this operation was recognized to be absolutely noncurative. The treatment of cardiovascular disease concomitant with malignancy remains controversial. The strategy to treat such patients is discussed in this report.

Celiac artery aneurysm (CAA) is very rare. We report a case of CAA with type IIIb aortic dissection (DA) which was treated surgically. A 60-year-old man who had an abnormal enlargement of the aorta on abdominal ultrasonography was admitted to our hospital. Angiography and CT scan revealed CAA with type IIIb DA. His general condition was stable and surgery was performed electively. The CAA was exposed through a median laparotomy. It was found to be about 3cm in diameter. As vascular reconstruction seemed difficult and the proper hepatic artery showed good pulsation after clamping the common hepatic artery, we decided to perform celiac artery aneurysmectomy without vascular reconstruction. Except for transient liver dysfunction, there was no other complication and he was discharged on the 24th postoperative day. During surgery for CAA, when collateral perfusion from the SMA to the liver is adequate, it seems that vascular reconstruction is not always necessary as shown by this case.
