A 67-year-old man was considered a candidtate for CABG because coronary angiogram showed obstruction segment 6 and stenoses of segments 9 and 12. He underwent emergency CABG due to acute myocardial infarction (AMI) with cardiogenic shock caused by hemorrhage from a gastric ulcer. Because of hypoxia due to pulmonary edema and acute renal failure an intraaortic baloon was inserted. He had a history of cerebrovascular stroke. Although coronary angiogram revealed multiple vessel disease, we performed off-pump coronary artery bypass (saphenous vein graft-left anterior descending artery) for salvage, because cardiopulmonary bypass was considered very risky and further systemic heparinization might be fatal. He has returned to his job, and is now free from angina. As AMI with cardiogenic shock is often caused by a lesion in the LAD, CABG without cardiopulmonary bypass may be an effective technique in certain selected patients.

A 9-year-old boy with multisaccular thoracic aortic aneurysm associated with coarctation of the aorta underwent definitive repair under partial cardiopulmonary bypass. The operation consisted of resection of the aneurysm and reconstruction of the descending aorta. Aortic reconstruction was done without an artificial graft, and extended end-to-end anastomosis was performed successfully. He has been doing well and there was no significant restenosis at the repair site 5 years after the operation. Some authors reported that untreated coarctation of the aorta frequently developed aneerysm, which usually has multisaccular lesions. Surgical strategy of aortic reconstruction for coarctation of the aorta in boyhood should be decided prudently to avoid postoperative complications.

BACKGROUND: We describe a 40-year-old Thai woman living in Japan who was transferred to Juntendo University Hospital after lung cancer was suspected. Chest X-ray showed a nodular lesion and pleural effusion in the left lung. Laboratory data showed eosinophilia. She denied having consumed raw or undercooked food at the initial interview. Microplate enzyme-linked immunosorbent assay (ELISA) for Paragonimus westermani specific immunoglobulin (Ig) G antibody was positive at a high titer, confirming the diagnosis of P. westermani infection. She was successfully treated with oral praziquantel. All primary practitioners should be aware that paragonimiasis is an important pulmonary disease that can cause nodular lesions on chest X-ray.

We report the case of a 59-year-old man who presented with classical-type fever of unknown origin (FUO) during observation of hypertension and polycystic kidney. The presence of malignancy was suspected based on elevation of tumor marker levels. We examined the patient carefully and attempted diagnostic imaging, but definitive diagnosis was difficult due to the presence of multiple hepatic cysts. Hepatic biopsy detected adenocarcinoma, but identifying whether lesions were primary cholangiocellular carcinoma or metastases was difficult, and we were ultimately unable to diagnose the tumors as cholangiocellular carcinoma until autopsy. Polycystic kidney with hepatic cysts and complicated by cholangiocellular carcinoma is rare, but should be considered among the differential diagnosis for FUO, which itself is frequently encountered.

A 77-year-old man had undergone CABG (coronary artery bypass grafting) (SVGs (saphenous vein grafts) to LAD (left anterior descending coronary artery), OM (obtuse marginal) and RCA (right coronary artery)) 15 years previously. Three years previously, he underwent CABG again (LITA (left internal thoracic artery)-OM, RGEA (right gastroepiploic artery)-RCA) due to recurrence of angina pectoris, but there was no evidence of graft disease in the SVG to the LAD. Six months before the present procedure, graft disease developed in the SVG to the LAD and caused unstable angina pectoris. Therefore, the left axillary artery was bypass grafted to the coronary artery (LAD) using SVG without cardiopulmonary bypass by means of the MIDCAB (minimally invasive direct coronary artery bypass) technique. The patient has had no angina pectoris subsequently. Postoperative angiography revealed that the graft was patent. The axillo-coronary (LAD) bypass appears to be a useful procedure for re-revascularization to the LAD in patients with no available arterial graft, such as ITA (internal thoracic artery) or RGEA.
