We experienced a case of @entity3526 ( @entity3526 ) with a specific form of obstruction of the right proximal subclavian artery. The @entity1 was a 44-year-old @entity1 who complained of numbness of the right hand. Right carotid-subclavian artery anastomosis was performed under general anesthesia. The obstructed segment was a fibrous cord, 3.5 cm in length and 2.0 mm in diameter. Postoperatively, the @entity1 was free from the symptom. In the Japanese literature, 73 cases of @entity3526 were reported from 1965 to 1986, and the etiology was mentioned in 64 cases. In 28 cases the cause was @entity12040 (43.8%), in 22 cases @entity4288 (34.4%), in 13 cases @entity600 (20.3%), and in 1 case iatrogenic lesion (1.6%). These data indicated that @entity3526 caused by @entity600 was not so rare as previously believed. Of 13 cases with @entity600 , our case and 3 other cases had similar aspect in clinical features. All 4 @entity1 were middle-aged @entity1 (aged 34, 26, 45 and 44 years) with a fibrous cord at the proximal portion of the right subclavian artery. None had any other @entity854 .
