Abstract

Spontaneous resolution of the arterial obstruction in Takayasu's arteritis is rarely reported. We reported a case of spontaneous resolution of an obstruction of the left subclavian artery in a young female. The patient underwent a bilateral coronary patch ostioplasty for both coronary ostial lesions complicated by Takayasu's arteritis at the age of 28. Concomitant left subclavian obstruction was seen at that time but left untreated. Surprisingly, the 10-year follow-up angiogram revealed complete resolution of the left subclavian artery obstruction. Meanwhile, no specific medical treatment was administered.

Figure

• 

  Fig. 1 Initial angiography shows a long segment obstruction of the left subclavian artery (arrows) with abundant collateral formation (A). Segmental stenosis of the right subclavian artery and the left vertebral artery (arrows) are also seen (B).

• 

  Fig. 2 An angiogram taken 10 years later reveals complete resolution of the left subclavian artery obstruction and the left vertebral stenosis along with disappeared collaterals (A). Segmental stenosis of the right subclavian artery has also disappeared (B).
