Morbidity in superficial thrombophlebitis and its potential surgical prevention.

Thrombophlebitis is a common condition which can lead to deep venous thrombosis (DVT) and subsequent pulmonary embolism (PE). Thrombophlebitis can reach the deep venous system via the long or short saphenous vein or via perforating veins. Between the 1st of January 1999 and the 31st of December 2000 a total of 17 cases of superficial (or ascending) thrombophlebitis closer than 5 cm to the deep venous system were surgically treated in our clinic. 14 times the long saphenous vein was affected and 3 times the short-saphenous vein. The age of the nine females and seven males ranged from 31 to 77 (mean of 54.6) years. Duplex ultrasound was performed in all patients. In the case of a deep venous thrombosis (four cases) a computer tomography scan (CT) of the pelvis and abdomen was performed to define the extension of DVT. In all 17 (100%) cases a high ligation (crossectomy) and in four (23.5%) cases a venous thrombectomy was performed. In all of these four cases the DVT was limited to the common femoral vein. In all seventeen procedures including venous thrombectomy there was no mortality and no relevant morbidity. Mean hospitalization time was 3.1 days for crossectomy with thrombectomy, and 1.8 days for crossectomy alone. Follow-up has been so far uneventful (mean follow-up time being 12 months in the case of a DVT). In the literature there is no clear concept of how to treat, conservatively or operatively, ascending thrombophlebitis. The surgical procedure can be performed under local anesthesia, and it is safe and efficient.
