[Compression therapy and deep-vein thrombosis: a clinical practice survey].

BACKGROUND

Compression therapy constitutes the cornerstone of prevention of post-thrombotic syndrome in patients with deep-vein thrombosis (DVT). However, no consensus has been reached regarding the optimal timing for initiation, duration, and strength of compression therapy.

OBJECTIVE

To document prescribing practices of compression therapy in case of DVT by French Vascular Medicine physicians.

METHODS

E-mail survey sent in 2009 to all physicians members of the French Society of Vascular Medicine.

RESULTS

Seven hundred and sixty-one vascular medicine physicians (56.6% private practice, 19.8% hospital-based and 23.6% both private practice and hospital-based physicians) responded. At diagnosis, 94.3% (n=707) systematically prescribed compression therapy. The initial compression consisted in elastic compression stockings (ECS) for 57.3% of patients (n=426) and in bandages for 42.7% (n=317). When physicians initially prescribed bandages, in 92.3% of cases they later switched to elastic compression stockings (ECS). Finally, 95.8% (n=712) of vascular medicine physicians reported prescribing ECS during DVT follow-up. The ECS ankle pressure gradient was 15-20 mmHg in 64.3% of cases and 20-36 mmHg in 35.5%. Most physicians (85.9%, n=631) modulated the duration of compression therapy according to the results of follow-up compression ultrasonographic explorations. Only a limited proportion of physicians took into account thrombus localization or its initial extention.

CONCLUSION

In case of DVT, French vascular medicine physicians systematically prescribed compression therapy. However, the strength of compression was lower than recommended by international guidelines. Efficacy and benefits (potential better compliance) of this common practice should be assessed with a randomized controlled trial.
