ABSTRACT
The middle aortic syndrome (MAS) is rare (about 0.5-2% of all the cases of aortic coarctation) vascular disorder characterized by severe narrowing in the descending thoracic aorta, abdominal aorta, or both. It can be congenital or acquired due to several conditions.MAS may present clinically as uncontrolled hypertension, abdominal angina or lower limb claudication. Surgical treatment is effective in controlling symptom and improves life expectancy.
ABSTRACT
A 51-year old woman was admitted to our hospital because of Exertional dyspnea, Palpitation, Headache, upper-limb hypertension, and lower-limb claudication. A loud systolic bruit was audible along Lt. carotid artery. Upper limb hypertension was responsed to drug moderately (included ACEI, alpha, beta-blocker, Ca++-channel blocker), but claudication of lower limb was aggravated, also on exertion, Blood Pressure of upper-limb was elevated to 180 mmHg. So, chest CT and Aortogram was performed, we confirmed long segmental stenosis from thorasic Aorta to the renal a. bifurcation level. Finally, We performed after axillo-femoral bypass surgery. After surgery, upper limb hypertension and lower limb claudication was improved.
