Evaluation of FUSION™ Vascular Graft for Above Knee Targets

Maquet Cardiovascular117 enrolled

Overview

The purpose of the post-market study was to evaluate the safety and performance of the FUSION Vascular Graft.

This study was a prospective, single-arm, multicenter study conducted in Germany and Austria to evaluate the FUSION Vascular Graft in patients with peripheral arterial occlusive disease undergoing above-the-knee bypass. Follow-up visits were performed at 30 days, 6 months, 12 months and included patency and post operative complications not associated with bypass patency.

Outcomes

Primary Outcomes

Participants With Primary Graft Patency at 12 Months

Subjects were assessed to have had primary graft patency at 12 months. A graft was considered to have primary patency if it had remained continuously patent (i.e., had continued blood flow through it) from the time of implantation and it had uninterrupted patency with no interventions. Patency was assessed by duplex ultrasound imaging.

Time frame: 12 Months

Secondary Outcomes

Participants With Secondary Graft Patency at 12 Months

Subjects were assessed to have had secondary graft patency at 12 months. Secondary graft patency was defined as a graft patency established by another intervention to remediate occlusion within 12 months after surgery.

Time frame: 12 Months

Mean Ankle-brachial Index at 30 Days, 6 Months and 12 Months

Ankle-brachial index at 30 days, 6 months, and 12 months. The ankle-brachial index is the ratio between the systolic pressure measured at the ankle and the systolic pressure measured in the arm.

Time frame: 30 days, 6 months, 12 months

Rutherford Category at 30 Days, 6 Months and 12 Months

Rutherford category at 30 days, 6 months and 12 months. Rutherford classification is a staging system to describe lower extremity ischemia, and is assigned by the Investigator. Higher grades represent more severe disease, ranging from asymptomatic (category 0) to major tissue loss (category 6).

Time frame: 30 days, 6 months, 12 months

Number of Participants Experiencing Major Adverse Limb Events and Periprocedural Death

Major Adverse Limb Events (MALE) were defined as major amputation (any amputation that resulted in limb shortening) or major graft reintervention (including placement of a new bypass graft at the same anatomic site, a jump/interposition graft, graft thrombectomy, graft excision (explant), or graft thrombolysis). Periprocedural Death (POD) was defined as death within 30 days of the index procedure or within 30 days of any remedial procedure performed at the same anatomical site or as a result of the initial procedure.
