title: Use of intravascular ultrasound to guide endovascular repair of popliteal artery aneurysms.
abstract: OBJECTIVE
  To evaluate the outcomes of intravascular ultrasound (IVUS) directed endovascular exclusion of popliteal artery aneurysm (PAA) using stent grafts.
  
  
  METHODS
  Clinical data of seven patients who underwent endovascular exclusion of PAA using IVUS guidance between 2009 and 2011 were retrospectively analyzed. Outcome measures included graft patency, endoleak, and clinical symptoms.
  
  
  RESULTS
  A total of seven patients were treated with Viabahn stent grafts using IVUS guidance. No patients were lost to follow-up (mean 12 ± 2 months). Patients had an average of two vessel runoff at the end of the procedure. All patients were symptom free with patent stents and no evidence of endoleak at follow-up.
  
  
  CONCLUSIONS
  Use of IVUS during endovascular treatment of PAA allows the physician to fully appreciate the anatomy of PAA, including location and extent of thrombus burden and the diameter and location of desired landing zones for appropriate sealing of the aneurysm proximally and distally. IVUS-guided treatment is associated with excellent outcomes and does not increase procedural radiation and contrast load.
