AIM: The aim of this paper was to report a 5-year single center experience with the use of percutaneous endovascular thrombosuction (PET) for acute lower limb ischemia (ALLI).
METHODS: All patients that underwent PET for ALLI within the period January 2009-December 2013 in our institution were included. Data were collected retrospectively.
RESULTS: A total of 262 patients (132 female, mean age 74.5±11 years) were treated. Level of severity of ALLI preoperatively was stratified as class I (viable) in 76% (199/262) of patients, class IIa (threatened marginally) in 19.4% (51/262), and class IIb (threatened immediately) in 4.6% (12/262). Initial technical success was 91% (237/262). Additional PTA was performed in 29.8% (78/262) of patients, and PTA with stenting in 27.5% (72/262). Open surgery due to technical failure of PET was required in 4.2% (11/262) of patients. Thirty-day mortality was 4.6% (12/262). Perioperative complications occurred in 9.2% (24/262). Thirty-day amputation rate was 3.8% (10/262). The mean duration of follow-up was 26.2±16 months. Estimated cumulative survival was 84.2±2.5% at 1 year, and 73.7±3.6% at 3 years. Estimated freedom from amputation during follow-up was 92.4±1.8% at 1 year, and 91.2±2% at 3 years. Estimated freedom from reintervention was 90.4±2% at 1 year, and 80±3.7% at 3 years.
CONCLUSION: PET in selected patients with ALLI provides high initial technical success, low mortality and morbidity rates, and favorable early and mid-term limb salvage rates.
