Dexamethasone Infusion to the Adventitia to Enhance Clinical Efficacy After Femoropopliteal Revascularization (DANCE)
調査の概要
詳細な説明
This is an investigator-initiated, single-arm, external pilot study to assess the safety and feasibility of perivascular administration of dexamethasone following endovascular superficial femoral and popliteal artery angioplasty or atherectomy.
Although dexamethasone is approved by the FDA for injection into blood, skin or joints, it has not been approved by the FDA for injection around blood vessels. The investigators want to find out if this procedure helps prevent re-narrowing of the blood vessel after angioplasty or atherectomy. The dexamethasone will be injected with a Bullfrog® Micro-Infusion catheter, which is an FDA-approved device for injecting medications into tissues around the blood vessel wall. The Bullfrog® Micro-Infusion catheter is similar to other balloon tipped catheters except that it contains a microneedle covered by a fold of semi-rigid balloon. Once the balloon is inflated, the microneedle is uncovered and a medication can be injected into the tissue around the blood vessel.

説明
Inclusion Criteria:
- Patient is > 40 years and < 80 years of age
- Patient has severe, lifestyle-limiting claudication or critical limb ischemia (Rutherford classification 3-6)
- Patient has TASC II A, B or C disease, SFA revascularization is preferred over medical management, and endovascular approach is preferred revascularization strategy

Perivascular administration of dexamethasone following endovascular superficial femoral and popliteal artery angioplasty or atherectomy.
|
Following a balloon angioplasty or atherectomy of a stenotic TASC II A, B, or C lesion in the superficial femoral or popliteal artery, a Bullfrog Micro-Infusion Catheter will be used to infuse 0.96 mg dexamethasone per cm arterial lesion.
