The Pounce™ Venous Thrombectomy System has demonstrated improvements in patient quality of life measures and disease severity scores at 12 months compared to baseline (p < 0.001).1

Villalta Score1: Median, [IQR], (N)

Baseline: 15.0, [7.0, 18.5], (19)

6 Month: 3.0, [1.0, 5.0], (13)

12 Month: 2.0, [1.5, 3.0], (11)

p < 0.001

Villalta score is a measurement tool that categorizes the severity of Post-Thrombotic Syndrome (PTS). A score >4 (or presence of a venous ulcer) indicates the presence of PTS. A score >14 indicates severe PTS disease.2

VCSS Score1: Median, [IQR], (N)

Baseline: 8.5, [7.0, 10.0], (16)

6 Month: 2.0, [2.0, 5.0], (13)

12 Month: 2.0, [1.5, 3.0], (11)

p < 0.001

Venous Clinical Severity Score (VCSS) may be used to assess changes in response to a given therapy. A total of 10 clinical descriptors are used (pain, varicose veins, etc.) are used to score disease severity (the worst being a score of 30).3
