The Department of Vascular Surgery deals with non-cardiac diseases associated with arteries, veins, and lymph vessels in the neck, chest, abdomen, and upper and lower limbs.
Medical services
Vascular surgery outpatient services are provided from Monday to Friday by a team made up of one associate professor, one lecturer, four assistant professors, and 10 graduate students. Three prescheduled surgeries are performed weekly and emergent surgeries are performed whenever required. Vascular imaging and function examinations are performed four times each week.
Diagnosis and treatment policy
In the first consultation, a non-invasive vascular function examination is performed. Based on the results of this examination and the systemic condition of the patient, a treatment strategy is developed. Many patients receiving treatment at the department are the elderly, for whom improvement in quality of life is taken into consideration.
Specialties
Patients with a wide range of vascular disease from around the country, including arterial diseases such as abdominal aortic aneurysm and arterial occlusive disease, venous diseases such as lower extremity varicose veins and deep venous thrombosis, and lymphatic vessel diseases, visit our department for treatment. Our department plays a leading role in Japan particularly in the diagnosis and treatment of critical limb ischemia. We also frequently perform minimally invasive treatments such as stent grafting for abdominal aortic aneurysm and endovascular treatment for arterial occlusion. As one of the most highly respected vascular surgery departments in Japan, our surgeons have always led vascular surgery practice in the nation. The most accurate diagnoses, the most effective treatments, the large number of surgeries performed, and our physicians’ abundant experience in this field are a source of great pride in the department.
Target diseases
Thoracoabdominal aortic aneurysm, abdominal aortic aneurysm, other aortic aneurysms, arteriosclerosis obliterans (ASO), Buerger’s disease, aortitis syndrome, carotid artery stenosis, Raynaud’s disease, traumatic arterial occlusion, acute arterial occlusion, internal shunt failure in dialysis patients, lower extremity varicose vein, deep venous thrombosis, angioma, arteriovenous malformation, lymphatic edema, etc.
Advanced treatments/ Specialized treatments
Stent grafting
Minimally invasive treatments are provided for patients with abdominal aortic aneurysm.
- Percutaneous angioplasty is an intravascular treatment for arterial stenosis which can be performed under local anesthesia
- Bypass surgery for lower leg and foot arteries in patients with critical limb ischemia, alleviating the need for lower limb amputation
- Laser treatment for varicose vein of lower extremities
Frequently performed tests
Outpatients
Vascular imaging examinations, vascular physiological examinations, vascular ultrasound examinations, etc.
Inpatients
Vascular imaging examinations; Mainly those requiring the Seldinger technique
