We report on a case of postoperative lobar torsion in a 51-year-old woman following right upper lobectomy. A right middle lobar torsion was diagnosed by postoperative observation with chest X-ray and bronchofiberscopy. An emergency rethoracotomy was performed and a middle lobectomy was carried out. The postoperative course was uneventful and the patient was(More)
Drug eluting stents (DESs) reduce the incidence of restenosis after percutaneous coronary intervention (PCI) and have been predicted to decrease the number of patients referred for coronary artery bypass grafting (CABG). We studied about the impact of DESs on CABG. We compared our isolated CABG patients over two years (May 2002-April 2004) before the(More)
Open heart surgery in patients with myelodysplastic syndrome (MDS) increases the risk of bleeding and infection. We document a 78-year-old female with severe aortic valve stenosis and MDS who underwent aortic valve replacement with stentless porcine prosthesis. Perioperatively, a transfusion of red blood cells (RBCs) and an infusion of granulocyte(More)
Coronary arteries with anomalous origin from the aorta can be a risk factor during aortic root procedures. We report on the successful management of aortic root surgery in a 76-year-old man with a single coronary ostium. Preoperative computed tomography and angiography revealed an anomalous course of the left main coronary artery from the right sinus of(More)
PURPOSE The Edwards Prima Plus stentless valve bioprosthesis (EPPSV) is a porcine aortic root cylinder with resected coronary ostia, fixed in glutaraldehyde at low pressure, and chemically treated to prevent calcification. Utilization of this valve was approved in January 2005 in Japan. The purpose of this study was to evaluate the early hemodynamic(More)
Two cases of drug-eluting stent restenosis after percutaneous coronary intervention in the left main coronary artery and its bifurcation are presented. An off-pump coronary artery bypass grafting following in-stent restenosis was performed. Drug-eluting stents have shown a reduced frequency of in-stent restenosis and a good safety profile compared with bare(More)
Surgical treatments of aortic root involvement in aortitis syndrome are frequently complicated by valve detachment and pseudoaneurysmal formation during active inflammation. A 40-year-old woman with aortitis syndrome complicating the ascending aortic aneurysm, severe aortic regurgitation (AR), and left coronary ostial stenosis was successfully treated by(More)
It is necessary to use side clamps to construct proximal anastomoses in off-pump coronary artery bypass, and this can be related to neurologic complications. Recently a new device, the HEARTSTRING device, was developed. We present a 78-year-old man who underwent emergent bypass surgery using the HEARTSTRING device to avoid a side clamp. We found(More)
The iliopsoas bursa is the largest bursa in the region of hip joint. It is unusual that these bursa become symptomatic. However the bursa can compress femoral vein, leading to lower extremity edema. A 58-year-old man was referred to our department for his unilateral leg edema which had been treated as deep vein thrombosis without any favorable response.(More)
