A 61-year-old man underwent thoracic aortic graft replacement and abdominal aortic graft replacement because of a dissecting aneurysm. He presented with a ruptured residual dissecting thoraco-abdominal aortic aneurysm and underwent emergency thoraco-abdominal aortic graft replacement in February 2007. An inverted bifurcated graft was fashioned by cutting one of the two graft legs and creating an elliptical patch, like a cobra-head. In order to prevent paraplegia after the operation, it was necessary to shorten the duration of spinal cord ischemia. Once the elliptical patch was sutured to the orifices of the internal costal arteries with running sutures, selective intercostal arterial perfusion was initiated by using a cardiopulmonary bypass. After the operation, he did not suffer paraplegia.

We describe a 77-year-old woman with severe aortic stenosis, porcelain aorta and coronary artery disease, who underwent apicoaortic bypass with coronary artery bypass grafting. The patient, who had a history of aortitis syndrome had dyspnea. Cardiac echocardiography showed severe aortic valve stenosis (aortic valve pressure gradient (max/mean) = 115/74.4 mmHg, aortic valve area = 0.48 cm2). Coronary angiography showed severe stenosis of right coronary artery orifice (#1.90%) . Computed tomography showed severe calcification of the thoracic aorta and surgical manipulation for ascending aorta was impossible. We did not perform ordinary aortic valve replacement. Instead, apicoaortic bypass with coronary artery bypass grafting was performed. We approached by a left anterolateral thoracotomy at the 6th intercostal level. Apicoaortic valved conduit (valved graft : Edwards Prima Plus Stentless Porcine Bioprosthesis 19 mm + UBE woven graft 16 mm) was implanted. Saphenous vein graft was harvested and coronary bypass grafting (valved conduit-#4AV) was performed in the same operative field. Postoperative cine MRI showed that most of the cardiac stroke volume flowed through the conduit (44.4 ml/beat, 92.3%), with the flow via the aortic valve accounting for 3.69 ml/beat, 7.7%. Postoperative enhanced CT showed that the coronary artery bypass graft was patent. Apicoaortic bypass is a good surgical option for aortic stenosis with severe calcification aorta and coronary artery bypass grafting can also be performed in the same view.

A 58-year-old man was admitted because of enlargement in diameter of the descending thoracic aorta. Six years previously, he had undergone graft replacement of the proximal descending aorta due to a chronic dissecting aneurysm. During that surgery, distal fenestration involving resection of the intimal flap of the distal anastomotic site and graft replacement with distal anastomosis of the true and false lumen were performed. Our preoperative enhanced computed tomography (eCT) revealed a thoracic aortic aneurysm 58mm in diameter at the site of distal fenestration. Graft replacement through left lateral thoracotomy was considered difficult because of previous occurrence of methicillin-resistant Staphylococcus aureus (MRSA) empyema after the previous operation: hence, endovascular repair was done using a handmade stent graft to interrupt blood flow into the false lumen. The postoperative course was uneventful. Postoperative eCT showed the thrombosed false lumen and the shrinkage of the aneurysm from 58 to 38mm in diameter over a period of 18 months.

We describe a novel method for repeat median sternotomy. We have successfully used ‘finger’ lifting resternotomy technique and achieved zero major cardiovascular injury/catastrophic hemorrhage events at reoperation. After general anesthesia, all patients were placed in the supine position and two external defibrillator pads were placed on the chest wall. We perform a median skin and subcutaneous incision along the previous sternotomy incision extending 3 cm distal to the sternum. The sternal wires that had been used for the previous closure were left in place but untied. Using a long electric cautery, right thoracotomy was performed under the right costal arch approach. Then, the operator could approximate the sternal wires in the retro-sternal space. At the same time, the operator could confirm the retro-sternal adhesion status which by touching with a finger. Resternotomy was performed using an oscillating saw pointed toward the operator's finger, which allowed safe re-median sternotomy from the lower to the upper part of the sternum. This technique of finger-lifting resternotomy has been employed in 50 cardiovascular reoperations and resulted in 0 incident of major cardiac injury or catastrophic hemorrhage. The finger-lifting resternotomy technique is safe and simple in reoperation procedures and yield excellent early outcomes.

Purpose: Head and neck cancer patients receiving chemoradiation therapy often suffer from severe mucositis. Chemoradiation therapy-induced mucositis is usually accompanied by severe and intractable pain that impairs quality of life. To establish an effective method for treatment of mucositis pain, we retrospectively investigated the relationships of radiation dose with severity of mucositis and opioid consumption. We also conducted a survey on satisfaction of pain treatment. Methods: Study 1: Fourteen patients who underwent chemoradiation therapy of 70 Gy for head and neck cancer from 2005 to 2009 participated in the study. The relationship of severity of mucositis with opioid use was studied. Study 2: Seven patients who had mucositis of over grade 3 and had completed radiation therapy participated in the study. We carried out a questionnaire survey about satisfaction of each pain treatment. Results: Study 1: Increase of radiation dose significantly worsened the severity of mucositis. Opioid consumption for treating pain was significantly greater in the pharynx cancer group than in the oral cancer group. Study 2: Oral care treatment was preferred to systemic administration of analgesics including opioids. Conclusions: In the oral cancer group, oral care treatment was thought to be useful for pain treatment. Oral cancer patients needed less opioids than did pharynx cancer patients.
