Subclavian steal syndrome (SSS) appears when the origin of the subclavian artery (SA) is occluded or stenosed. Introduction of transcranial Doppler sonography (TCD) provided an opportunity to evaluate parameters of the blood flow in the vertebral (VA) and basilar artery (BA). Measurements of blood flow velocities performed at rest and after the brachial hyperemia test allow one to classify hemodynamic types of SSS. ⋯ In one case the latent vertebral steal was detected. The 28 months mean follow-up revealed no significant changes in TCD flow patterns recorded from VA's and BA. After collecting data of about 60 patients with SSS we examined with TCD we conclude that: in patients with a hemodynamically significant SA stenosis the presence of reversed ipsilateral VA blood flow (a radiologic steal) its not a good determinant of either the presence or type of presenting symptoms and after successful PTA or recanalisation and PTA of SA in almost all cases we examined close to normal TCD recordings in BA and VA.

In the Department of General and Thoracic Surgery between 1981 and 1992 497 patients with tracheal stenosis were treated surgically. In 19 (3.8%) cases the stenosis was after previous tracheostomy. In 469 patients (94.4%) the stenosis was caused as the result of compression by goitre and in 9 (1.8%) by neoplastic tumors of mediastinum. ⋯ In patients with secondary stenosis due to compression by goitre subtotal thyroidectomy was performed. Early good immediate results in both groups of tracheal stenosis were obtained in 90% of cases. Late results obtained 12 months after treatment of primary tracheal stenosis and 4 to 48 months after treatment of secondary tracheal stenosis (due to goitre) revealed 90% of good results.
