ABSTRACT
We sometimes encounter the case that we have to make an anastomosis between a prosthetic graft and an autologous vein graft in revascularization of a lower extremity. However, it is said that the intimal hyperplasia in the anastomosis site of a prosthetic graft and autologous vein graft has a tendency to become severe in the long term postoperatively. We herein report a case in which a vein cuff (St. Mary's boot) technique was very useful to prevent recurrent stenosis due to intimal hyperplasia. No recurrence of stenosis in repair lesion has been detected for 7.5 years after operation.
ABSTRACT
We present a successful case of a patient with multiple metal allergy—cobalt, nickel, chromium, and zinc—who had a past history of systemic metal dermatitis. He was a 58-year-old man who complained of exertional chest discomfort. After admission, he had a fever and his blood culture was positive with methicillin-sensitive Staphylococcus aureus. Three days later, multiple micro cerebral infraction was detected in magnetic resonance imaging. After an improvement of inflammatory reaction, he was transferred to our facility for cardiac examination. Moderate mitral regurgitation due to valve perforation and multiple coronary vessel stenosis were detected. Mitral valve replacement and coronary artery bypass grafting were planned to perform. We chose surgical materials based on a preoperative epicutaneous (patch) test and his clinical course was uneventful without any allergic reaction. Metal contact allergy is an important issue in cardiovascular surgery. A collaboration with dermatologists is essential for the preparation of surgical materials.
ABSTRACT
We investigated how cardiovascular surgeons get a day off.
ABSTRACT
We describe a rare complication and treatment progression that occurred in a 64-year-old man with an aortic abdominal aneurysm (AAA) that had been treated by endovascular aneurysm repair (EVAR). He had undergone EVAR to treat an infra-renal type AAA 21 months previously and returned to the emergency department with back pain. Contrast-enhanced computed tomography (CT) revealed acute type B aortic dissection, so he was admitted and conservative medical management was started. Acute stomachache and limb pain appeared on hospital day 7, which prevented him from moving his lower limbs. The main body of the stent graft had collapsed, blocking blood flow, and contrast was not found in arteries from the collapsed stent graft portion to the knee level on emergency contrast CT images of the leg. His legs were revascularized by an extra-anatomical right axial-bilateral external iliac bypass. His symptoms disappeared and reperfusion injury was avoided. The collapsed stent graft had retained its original shape at 11 and 18 days after surgery. Furthermore, follow-up CT 4.5 years later showed that the stent graft retained its original form.
ABSTRACT
A 47-year-old female was admitted to our hospital for management of dyspnea. She had undergone surgery for an atrial septal defect (ASD) at the age of 17. Computed tomography revealed left isomerism, inferior vena cava interruption with azygos continuation and a residual ASD. Intra-operative findings showed that the residual ASD was positioned across the orifice of the hepatic vein. The previous suture line could be identified in the partially-closed atrial septum above the residual defect. Re-closure was performed without difficulties, and the patient's condition was good at discharge. Closure of ASD is a simple and basic procedure in cardiac surgery but care must be taken not to leave a shunt at the lower part of the defect, especially in cases with ASD defects in the lower margin.
ABSTRACT
A 67-year-old man with dilated cardiomyopathy was admitted to our hospital for treatment of cardiac failure. After using heparin because cerebral infarction developed during hospitalization, in acknowledgment of thrombocytopenia, we reach the diagnosis of HIT. We judged surgery to be necessary because heart failure had difficulty with catecholamine secession and the left ventricular dilation progressed rapidly, and performed left ventriculoplasty, mitral valve plasty. There were no complications such as the thrombosis during cardiopulmonary bypass, and the postoperative course was good without leading to re-thoracotomy due to bleeding. He passes without a heart failure symptom by the follow of one year 6 months after surgery at home.
