Duplex sonography of vas­cu­lar­iza­tion of ­venous throm­bo­sis

Background. Changes in the echog­e­nic­ity of an age­ing intra­ve­nous throm­bus have ­already been ­described in B-mode sonog­ra­phy. We tried to inves­ti­gate the phe­nom­e­na of vas­cu­lar­isa­tion of the intra­ve­nous throm­bot­ic mate­ri­al dur­ing the organ­isa­tion using ­colour Doppler sonog­ra­phy.
Methods. We carried out a pros­pec­tive inves­ti­ga­tion of 8 jug­u­lar vein, 6 femo­ral vein and 1 infe­ri­or caval vein throm­bo­sis. The throm­bos­es were inves­ti­gat­ed with a ­colour Doppler son­o­graph­ic ­device from Siemens, type Elegra, every sec­ond or third day for 4 weeks after mak­ing the diag­no­sis. We ­looked for intra­throm­bot­ic ­colour Doppler sig­nals with an arte­ri­al pul­sa­tile blood flow in the ­pulsed Doppler mode.
Results. We found arte­ri­al sig­nals in the intra­ve­nous throm­bus in 8 of the 15 ­patients. Such arte­ri­al Doppler sig­nals were sup­posed to be arte­ri­al ves­sels which devel­op dur­ing the organ­isa­tion of the throm­bot­ic mate­ri­al. The arte­ri­al ves­sels ­appeared only in a short range of time from the 11th to the 25th day and were ­present in cir­cum­scribed areas of the throm­bus. Arterial blood ves­sels in the sur­round­ing tis­sue of the veins which may sup­ply blood to the intra­throm­bot­ic ves­sels could not be dem­on­strat­ed.
Conclusions. Thus the intra­ve­nous doc­u­men­ta­tion of arte­ri­al ves­sels in an organ­is­ing intra­ve­nous throm­bus is pos­sible. This may give infor­ma­tion about the mech­a­nism of throm­bo­gen­e­sis and about the ­degree of organ­isa­tion and may also help in determ­ining the age of the throm­bo­sis.
