A 60-year-old woman with hypertension for 40 years had presented the hypertensive heart failure due to an atypical coarctation of the aorta. The difference of blood pressure between upper and lower limbs reached 110 mmHg with taking 6 kinds of antihypertensive drugs. Her blood pressure declined without antihypertensive medication and heart failure got subsided after the extra-anatomical bypass of axillobilateral external iliac artery bypass. Extra-anatomical bypass for Takayasu's arteritis had enough effects to improve the hypertension and was supposed to have the advantages of decreasing the operative risk, and preventing the aneurysmal formation of anastomotic site rather than the thoracoabdominal aortic bypass.
