title: Percutaneous endovascular thrombosuction for acute lower limb ischemia: a 5-year single center experience.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  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.
