A ­case of super­i­or ­vena ­cava throm­bo­sis sec­on­dary to ­the tho­rac­ic out­let syn­drome is report­ed. The diag­no­sis ­was ­revealed by CT-­scan ­and con­firmed by phle­bog­ra­phy per­formed to ­insert a cath­e­ter ­for intra­throm­bot­ic infu­sion of urok­i­nase. The throm­bo­lyt­ic treat­ment ­was fol­lowed by com­plete ­clot ­lysis. A hyper­ab­duc­tion manoeu­vre con­firmed costoc­la­vic­u­lar com­pres­sion as ­the ­cause of ­the sub­cla­vian-axil­lary ­vein throm­bo­sis ­for ­which ­the ­patient under­went ­first ­rib resec­tion. Axillary-sub­cla­vian ­vein throm­bo­sis (or Paget-­von Schroetter syn­drome) is a rel­a­tive­ly fre­quent com­pli­ca­tion of ­the tho­rac­ic out­let syn­drome ­often treat­ed ­with anti­co­ag­u­lants on ­the ­basis of a ­duplex exam­ina­tion. Involvement of ­the super­i­or ­vena ­cava is ­not read­i­ly detect­ed by ­duplex ultra­sound so a par­tial throm­bo­sis, ­with a pos­sible ­fatal out­come ­could ­remain undi­ag­nosed. Full inves­ti­ga­tion by phle­bog­ra­phy or CT-­scan is there­fore rec­om­mend­ed. In addi­tion, trans­cath­et­er throm­bo­lyt­ic ther­a­py ­has a low­er inci­dence of fol­low-up com­pli­ca­tions ­than hep­ar­in.
