Brief Summary
The purpose of this protocol is to study the safety and feasibility of using ultra-low dose iodinated contrast agent for infrainguinal endovascular revascularization procedures in patients with chronic limb-threatening lower limb ischemia (CLTI) and impaired renal function, in the new angiography suite of our department.

Study Arms (1)
Study cohort
Patients with renal disease stages 2-4, scheduled to undergo infrainguinal endovascular procedures due to CLTI, using ultra-low dose of iodine contrast media.
Interventions
Percutaneous endovascular angioplasty and/or stenting of infrainguinal arteries (femoropopliteal and/or infrapopliteal arteries) under local anesthesia and adjunct mild conscious sedation.
Eligibility Criteria
Patients suffering from renal impairment stage 2 to 4 and chronic -limb-threatening ischemia (CLTI)
You may qualify if:
- CLTI
- Prescheduled infrainguinal revascularization procedure
- Renal disease stage 2-4 (eGFR \<60ml/minute/1.73m2)
- Adequate pre- and post-procedural hydration protocol
You may not qualify if:
- Inadequate pre- and post-procedural hydration protocol
- End-stage renal disease/ dialysis
- eGFR \>60ml/minute/1.73m2)
- Endovascular treatment of Iliac artery steno-oclussive disease
- Allergy to contrast media
