AbstractThirtvine cases of thoracic outlet syndromeincluding 32 women and 7 men,treated withsurgery from July 1986 to August 1990 were ana-lyzed.The age ranged from 12 56,30 were be-tween 20 40 years of age,The average follow up period was 28 64 months.33 cases had pares-thesia of the anterior medial aspect of the forearm,which was the basic finding for the diagnosis ofthoracic outlet syndrome. 89%of the cases had a-trophy of the intrinsic muscles and paresthesia ofthe ring and small fingers,indicating involvementof the C8 and T1 nerve roots,28 cases had cervi-cal rib and overlength of C7 transverse process. The positive rates of the 4 special tests (Wright,Adson, Roos and Eden)were below 50%,howev-er,the correlation between positive Adson testand elevated subclavicular artery found in opera-tion was of significance(P 0.05). 8 cases hadtingling and pain of radial 3 fingers indicating C7compressiosn. The operatiave procedures mainlvconsisted of severance of scalenus muscle or fi-brous band and resection of cervical rib or trans-verse process. Excellent results were obtined in79. 49% of the cases.Resection of the first ribshould not be done routinely so as to avoid compli- cations.
