Abstract
Objective:
Patients with critical limb ischemia (CLI) and gangrene have a 10% to 38% rate of major amputation at 6 months. The purpose of this study is to report short- and mid-term major and minor amputation rates for patients who underwent tibial and pedal revascularization in addition to quality-of-life (QoL) scores.
Methods:
All patients who presented to a single institution with CLI (defined as rest pain or nonhealing wounds) and underwent antegrade or retrograde tibial access, atherectomy and angioplasty of the tibial circulation, and angioplasty of pedal circulation (antegrade or retrograde) from June 2016 to September 2017 were included. The Stark QoL questionnaire was used at each visit. Patients were scored at 1, 3, and 6 months postprocedure. Amputation rates were recorded.
Results:
Forty-two patients with CLI and gangrene underwent 57 peripheral interventions for limb salvage between June 2016 and September 2017. Thirty-two limbs had dry gangrene along the dorsalis pedis angiosome, 14 limbs had dry gangrene along the posterior tibial angiogram, and 11 limbs had a combined disease pattern. Twelve limbs underwent angioplasty of the superficial femoral artery (SFA), 18 limbs underwent angioplasty and stenting of the SFA, and 14 limbs underwent atherectomy, angioplasty, and stenting of the SFA. All patients had 1 or 2 tibial vessel runoff and high-grade stenosis of the pedal circulation. Immediate technical success defined as 3-vessel outflow to the foot occurred in 49 limbs (86%) with zero 30-day complications (30-day readmission, major amputation, or sepsis). Major amputation rate at 1, 3, and 6 months was 0%, 2%, and 4%, respectively. Patient satisfaction in terms of QoL increased over the 6-month follow-up period.
Conclusion:
Aggressive tibial and pedal revascularization may improve freedom from minor and major amputation at 6 months and may be associated with a short- and mid-term higher QoL.
