RESUMEN
We report a rare case of a giant right coronary artery aneurysm 13 years after coronary artery bypass grafting. Coronary angiography at the time of primary surgery demonstrated irregular aneurysmal dilatation in the mid-right coronary artery that expanded greatly over a 13-year period to a maximum diameter of 80 mm. The patient underwent aneurysmectomy and interposition using a saphenous vein graft through a right lateral thoracotomy. The patient did not undergo dissection or clamping of the left internal thoracic artery graft, and myocardial protection was obtained using systemic hypothermia and hyperkalaemia in addition to continuous antegrade cardioplegia. Postoperatively, coronary computed tomography showed a lack of residual aneurysm and good flow in the saphenous vein graft. The patient made an uneventful recovery.

A 60-year-old male was referred to our institution for investigation of intractable hypertension. Coarctation of the aorta was detected by computed tomography (CT). Bilateral internal thoracic arteries played an important role as a collateral source to the lower extremity. Coronary angiography showed stenosis at the ostium of left main trunk. Ascending aorta to bilateral external iliac artery bypass grafting and off-pump coronary artery bypass grafting (OPCAB) was done simultaneously, this is because we had to harvest left internal thoracic artery as a conduit for coronary artery bypass grafting(CABG).Postoperative course was uneventful. The patient was discharged 10 days after the operation. We could perform less-invasive surgery despite the simultaneous operations.

Three abnormal shadows were detected in the right lung on chest X-ray films and computed tomography in a 75-year-old woman during follow-up for idiopathic thrombocytopenic purpura. Because a definitive diagnosis was not obtained through general examinations, exploratory thoracotomy was performed for diagnosis and treatment. The main lesion in the right middle lobe was diagnosed as mucosa-associated lymphoid tissue (MALT) lymphoma according to histopathological findings, cytogenic studies and reverse transcriptase-polymerase chain reaction analysis, and nodular lesions in S(3) and S(7) were diagnosed with Congo-red staining as local deposition of amyloid. The patient had no recurrence of the MALT lymphoma of the lung or other organs for 4 years after surgery. To our knowledge, this is the first reported case of primary pulmonary MALT lymphoma combined with idiopathic thrombocytopenic purpura/lung amyloidoma.
