Further study details as provided by University of Vermont:

Primary Outcome Measures:

To determine if complex lymphedema therapy improves the quality of life in patients with post-thrombotic syndrome [ Time Frame: 1 and 3 months ] [ Designated as safety issue: No ]
To determine if complex lymphedema therapy reduces disease severity in patients with post thrombotic syndrome [ Time Frame: 1 and 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To assess side effects of lymphedema therapy when administered to patients with PTS [ Time Frame: 1 and 3 months ] [ Designated as safety issue: Yes ]
To determine if selected biomarkers correlate with disease severity and response to lymphedema therapy in patients with post thrombotic syndrome [ Time Frame: 1 and 3 months ] [ Designated as safety issue: No ]

Estimated Enrollment:	44
Study Start Date:	March 2008
Estimated Study Completion Date:	August 2009
Estimated Primary Completion Date:	August 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
A: Experimental Complex lymphedema therapy (which includes compression stocking use)	Other: complex lymphedema therapy Patients with established post thrombotic syndrome will be randomized to either compression stocking use or complex lymphedema therapy.
B Standard of care (compression stocking use at 30-40 mm Hg)	Other: complex lymphedema therapy Patients with established post thrombotic syndrome will be randomized to either compression stocking use or complex lymphedema therapy.

Detailed Description:

Post thrombotic syndrome (PTS) has a spectrum of disease manifestations ranging from minor skin discoloration to severe skin changes and venous ulcerations. Pain is often a prominent symptoms and PTS impairs patient quality of life. Prevention of PTS using compression stockings has been emphasized. There is a paucity of validated, effective treatments for PTS once the condition develops.

While the pathophysiology of PTS is incompletely understood, chronic venous hypertension and insufficiency may increase the workload of the lymphatic system and result in over-capacitance with secondary damage and eventual lymphatic insufficiency. In selected patients with PTS, we have noted a symptomatic improvement in patients who receive lymphedema therapy to the limb. Complex lymphedema therapy (CLT) is a noninvasive treatment that includes four key components: meticulous skin care, manual lymph drainage, compression therapy, exercises and patient education for home management and continuation of the treatment. These techniques are designed to enhance lymph flow through intact cutaneous lymphatics and reduce swelling and restore function in the affected limb.
