Time Frame: Baseline (within 30 days of treatment), Day 30
|
Clinical efficacy was evaluated using the Villalta score at Baseline compared to 30 days Post-EkoSonic® study treatment procedure.
Villalta scale (post thrombotic syndrome score) is used for the assessment of symptoms and clinical signs.
Participants rated the following symptoms for each leg: pain, cramps, heaviness, pruritus, and paresthesia on a scale ranging from 0 (not present/minimal) to 3 (severe).
The study coordinator or nurse rated the following clinical signs in participants for each leg: pre-tibial edema, induration of the skin, hyperpigmentation, new venous extasia, redness during calf compression, and pain during calf compression on a scale ranging from 0 (not present/minimal) to 3 (severe).
Total score ranged from 0 to 33.

Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Ouriel Score (Venous Volumetric Index [VVI]) at Post-Adjunctive Therapy
Time Frame: Baseline (Within 30 days of treatment), Day 0
|
The Ouriel score was designed to provide a more accurate quantitative estimate of the thrombus mass by calculating a volumetric index for all the venous segments.
10 venous segments were considered.
Included segments were the inferior vena cava, common iliac veins, external iliac veins, internal iliac veins, common femoral veins, superficial and deep femoral veins, and popliteal veins and segments of the anterior tibial veins, posterior tibial veins, and peroneal veins.
A normalized volumetric score was calculated for each segment by combining measurements from computed tomography, ultrasonography, and venography.
Partially occluded veins were assigned a score of one-half the score value for the segment.
The score varies from 1 for a single calf vein to 26 for the infrarenal inferior vena cava.
The maximum score was 63 per limb.
Higher score indicated worse disease prognoses.
