Study summary

The objective of this study is to obtain outcomes following dissection repair with the Tack Endovascular System in a broad population of patients undergoing endovascular treatment of lesions within the superficial femoral, popliteal, peroneal, and/or tibial arteries.

Read the detailed description

The purpose of this post-market study is to obtain outcomes following dissection repair with the Tack Endovascular System in a broad population of patients undergoing endovascular treatment of lesions within the superficial femoral, popliteal, peroneal, and/or tibial arteries.

The Tack Endovascular System has been shown to effectively repair dissection and improve outcomes in clinical studies. Additional data, such as clinical utility of the Tack Endovascular System with the combined use of adjunctive therapies - other than balloon angioplasty alone, is needed.

Patients with claudication or CLI, who meet Rutherford classification 3, 4, or 5 criteria if ATK and Rutherford classification criteria 4 or 5 if BTK, who have undergone an above the knee (ATK) or below the knee (BTK) endovascular procedure utilizing adjunctive therapies other than balloon angioplasty alone which are then followed by PTA and IVUS, and have an arterial dissection requiring repair.

Approximately 100 subjects will be enrolled in up to 10 sites. The enrollment will be capped as follows:

  • ATK: 50% of subjects
  • BTK: 50% of subjects

After enrollment of planned 100 subjects and interim analysis, the study may enroll up to 200 additional subjects at up to 20 additional sites, with each site limited to 15% of total enrollment.

  39. Quality of Life / EuroQol EQ-5D-5L

    Changes from baseline in EQ-5D-5L questionnaire. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.
