Vascular Surgery Director:BANNO, Hiroshi (Professor)

Vascular specialists hold a full-time position and have high expertise

We perform diagnosis and treatment of vascular diseases (e.g. arteries, veins, lymph vessels), aneurysm, and peripheral arterial diseases (surgical treatment, stent graft, and endovascular treatment).


Medical Care System

We perform diagnosis of and provide medical care for all vascular diseases. The outpatient clinic days are Monday, Wednesday and Friday, and treatment days are Monday, Tuesday and Thursday; however, we also accept emergency patients every day.

Target Diseases

All vascular diseases. Arterial disease includes aortic aneurysm (thoracic, thoracoabdominal, and abdominal), arteriosclerosis obliterans, Buerger's disease, carotid artery stenosis, and renal artery stenosis; venous disease includes varicose veins of the lower extremities and deep vein thrombosis; lymphatic disease includes lymphedema.

Strong Fields

For thoracic and abdominal aortic aneurysm, we have performed stent graft implantations as well as surgery. For patients with peripheral arterial occlusive disease, we perform bypass surgery and endovascular treatment suitable for the clinical conditions; for patients in whom revascularization is unfeasible, we perform angiogenic therapy. We also conduct laser therapy for varicosis.

Clinical Results

In 2020, we treated 94 patients with abdominal (iliac) aortic aneurysm (stent graft implantation: 57 patients), performed stent graft implantation for thoracic aortic aneurysm in 40 patients, PAD in 126 patients (of whom 32 patients received bypass surgery), and treated varices in 21 patients.

Specialized Outpatient Clinic

The expertise of vascular surgery specialists is extremely high because not all hospitals have the department of vascular surgery: six cardiovascular surgery specialists; six vascular specialists; and, five stent graft supervising doctors hold full-time positions in our department.

Advanced Medicine and Research

For advanced medicine, we perform angiogenic therapy using autologous bone marrow cell transplantation. We are involved in the elucidation of the origin of vascular intimal hypertrophy and its control by gene therapy, elucidation of the origin of aneurysm, improvement of treatment results of stent graft implantation, and molecular biological research on inflammatory vascular disease.
