Acute superficial venous thrombophlebitis: does emergency surgery have a role?

BACKGROUND

Superficial venous thrombophlebitis (SVT) of the long saphenous vein (LSV) has been shown to be associated with thrombus propagation into the common femoral vein in up to 44% of cases. Conservative management can thus result in deep vein thrombosis (DVT), deep vein insufficiency or fatal pulmonary embolism (PE). To examine the effects of emergency division of the sapheno-femoral junction (SFJ) on the deep venous system in SVT of the LSV we used pre- and postoperative venous duplex ultrasound.

METHODS

Emergency division of the SFJ was performed in 17 patients presenting with acute superficial venous thrombophlebitis. All patients had duplex ultrasound, which demonstrated thrombus of the above knee long saphenous vein together with a normal deep venous system. A follow-up duplex ultrasound scan was arranged on discharge and at 2 months.

RESULTS

No patient had propagation of thrombus into the deep venous system or a PE. One patient developed a non-occlusive clot in the popliteal vein at 2 months follow-up. All patients were discharged at 48 hours.

CONCLUSIONS

Using duplex ultrasound it has been shown that emergency division of the SFJ is a safe and effective way of preventing serious complications caused by thrombus in above knee LSV SVT.
