Aortitis syndrome due to Takayasu's disease. A guideline for the surgical indication

Seven cases of aortitis syndrome were surgically treated with good results: Abdominal aortic aneurysm 1, atypical coarctation of aorta 2, aortic valve insufficiency 2, renovascular hypertension 2. Several attentions were paid as following: 1. Operation should be avoided during acute phase of aortitis. 2. Synthetic graft material should be avoided if possible. Autogenous vein is advisable for reconstruction of small-sized artery. 3. Surgical intervention should be performed before the loss of organ function. 4. Hematological consideration is worthwhile to prevent hypercoagulopathy due to aortitis.
