Axillo-Bifemoral Artery Bypass for Atypical Coarctation / 日本心臓血管外科学会雑誌

ABSTRACT

In 46-year-old man who had had general fatigue due to hypertension for about 20 years, only hypertension of the upper part of the body had been pointed out; the blood pressure of the upper limbs was 190mmHg and that of the lower limbs was 80mmHg. Computed tomography showed severe aortic stenosis with advanced calcification from the proximal descending thoracic aorta to the infra-renal abdominal aorta, the minimum caliber of the aorta being only 5mm. Hypertension was not controlled in spite of administration of 5 anti-hypertensive agents. Because renal factors were not related to hypertension, we chose a minimally invasive procedure axillo-bifemoral artery bypass. After operation, the difference of blood pressure between upper and lower limbs reduced and symptoms disappeared. There are many case reports of aorto-aortic bypass for atypical coarctation, but we think that the less invasive axillo-bifemoral artery bypass is also an alternative procedure.
