[Ultrasonographic findings in varicose phlebitis of the great saphenous vein. Evidence of thrombus growth and detachment with asymptomatic lung embolism].

In five women (mean age 58 [31-74] years) with clinically diagnosed varicose phlebitis of the long saphenous vein appositional thrombus growth was demonstrated by serial ultrasonography (B-mode compression and colour-coded duplex sonography). In one patient the appositional thrombus was found to be free-floating as far as the common femoral vein, but this was not seen by phlebography. During therapeutic heparinization there was ultrasonographic evidence of softening and partial liquefaction of thrombus material in a cranial direction. There were no clinical signs of pulmonary embolism, but pulmonary perfusion scintigraphy demonstrated perfusion deficit characteristic of emboli. Four of the five patients had a surgical crossectomy and partial saphenous vein resection. The congruence between ultrasonographic and macro- as well as micropathological findings demonstrates the great value of B-mode and duplex ultrasound examination in the area of the epifascial veins. Ultrasonography should be performed in every case of varicose phlebitis of the large veins to exclude the presence of apposition thrombi.
