ABSTRACT
A 74-year-old man having a right refractory foot ulcer was referred to our hospital with a diagnosis of arteriosclerosis obliterans. Angiography of the lower extremities showed occlusive lesions in the middle popliteal artery and lower-leg arteries. Preoperative examination revealed decreased cardiac function and severe stenosis of the left and right coronary arteries. Therefore, we first performed coronary artery bypass grafting, followed by revascularization of the lower limbs at a later date. Owing to the lack of suitable autologous vein grafts, our procedure of choice was popliteal endarterectomy via a posterior approach with short saphenous vein angioplasty. The patient's foot ulcer healed completely following surgery. His postoperative course was uneventful, and he remained symptom-free during a 1-year follow-up.
ABSTRACT
A 64-year-old man under dialysis was referred for surgical treatment of Crawford type I thoracoabdominal aortic aneurysm. He had a history of idiopathic portal hypertension and chronic total occulusion of supra-renal abdominal aorta and appeared to have massive development of collateral arteries and veins in the abdomen. We chose endovascular repair with debranching of visceral arteries and bypass grafting to bilateral superficial femoral artery considering bleeding from collateral arteries and veins by conventional open surgery. Postoperative CT scan revealed no endoleak and all debranched and bypass grafts were patent. He was discharged with no postoperative complications including paraplegia.
ABSTRACT
Congenital anomalies of the coronary artery are rare. However, they can cause sudden death because of arrhythmia. We present a case of a 62-year-old man with severe aortic valve regurgitation associated with an anomalous origin of a narrowed right coronary artery (IB<sub>2</sub> according to the Shirani Classification) detected on preoperative coronary three-dimensional computed tomography (CT) . The patient underwent both aortic valve replacement for aortic regurgitation, and coronary artery bypass. The postoperative course was uneventful.
ABSTRACT
We conduct an outpatient escort program as a part of our early exposure curriculum for first-year medical students. Each student escorts one patient at the University of Tsukuba Hospital throughout his or her first visit. We evaluated this program from the points of view of both students and patients.<BR>1) A questionnaire was distributed to all participating patients and students in 2006.<BR>2) In their questionnaires, many students commented on the long waiting time, the structural problems of the hospital, and the attitudes of physicians.<BR>3) Results of the questionnaire showed that both students and patients rated this program highly.<BR>4) No significant differences were noted between the comments of the students and those of the patients. The patients tended to rate this program more highly than did the students. One patient, however, commented that being constantly accompanied by a stranger was somewhat stressful.<BR>5) We conclude that this program can be efficiently carried out without being too much of a burden to patients and is a valuable part of an early exposure program for first-year medical students.
ABSTRACT
Students in their 5th and 6th year of University of Tsukuba, School of Medicine, enter into a clinical clerkship. They record medical charts and flow sheets and they present at clinical rounds.<BR>1) From 2000 to 2005, a questionnaire survey was conducted to evaluate the clinical clerkship in the rheumatology division. We also evaluated the influence of the introduction of infliximab therapy (October 2003) on the students' experience.<BR>2) Evaluation of the clinical clerkship by the students was improved by attending the infliximab ward. Students felt more involved in the treatment of the patients by preparing drip infusion sets, disssolving infliximab, assisting with the drawing of blood and drip infusions, checking of the vital signs every 30 minutes, and recording charts.<BR>3) Students realized the improvement of rheumatoid arthritis with therapy and the changes in the patients' emotional status after the introduction of infliximab.
ABSTRACT
We conducted an outpatient escort program as a part of our early exposure curriculum for first-year medical students. Each student escorted one patient at the University of Tsukuba Hospital throughout his or her first visit. This program enabled the students to experience and think about the system of a university hospital from a patient's point of view. We believe that this program is useful to motivate first-year medical students in their future studies.
ABSTRACT
We reviewed our experience with 19mm size aortic valve prostheses for cases with small aortic annulus. Forty-six patients operated on between 1990 and Septembr 2002 were enrolled in this study. Clinical late assessment was performed to evaluate the incidence of valverelated complications, residual transprosthetic gradient, left ventricular mass index (LVMI), and NYHA functional class. Postoperative echocardiography was performed to evaluate hemodynamic performance of the prostheses. Follow up was 1 to 12.7 years (mean 5.3±3.6). There was no hospital mortality (0%). Actuarial survival rates at 10 years were 81.4±1.5%. The late postoperative peak gradient was 25±11mmHg. LVMI was significantly reduced in late phase. NYHA functional class significantly improved in the late period. Although 19mm size aortic valve prosthesis remains small transprosthetic pressure gradient, LVMI significantly reduced and patient activity was satisfactory maintained in the late period.
