NCT01385774

Brief Summary

The purpose of our study is to compare the clinical effectiveness and cost-effectiveness of two treatment strategies of Intermittent Claudication (IC) due to an iliac artery obstruction: to start with SUPERvised Exercise Therapy (SET) and deferred Percutaneous Transluminal Angioplasty (PTA) in case of SET failure, or immediate PTA. It is our hypothesis that PTA as first line treatment is more effective than SET as first line treatment with regard to maximum walking distance, quality of life and costs after one year.

Outcome Measures

Primary Outcomes (2)

  • Disease specific Quality of Life

    Disease specific Quality of life (Qol) recorded with the disease specific VascuQol instrument 1 year after intervention. The VascuQol will be completed at baseline and 1,6,12 months follow-up.

    12 months

  • Maximum Walking Distance

    Maximum walking distance on a standardized treadmill test with a speed of 3.2 km/h at 10% incline measured 1 year after intervention. The maximum walking distance will be assessed at baseline and 1,6,12 months follow-up.

    12 months

Secondary Outcomes (6)

Study Arms (2)

Intervention group: Angioplasty

ACTIVE COMPARATOR

Angioplasty with or without stent of the iliac artery

Procedure: Percutaneous Transluminal Angioplasty

Control: Supervised Exercise Therapy

ACTIVE COMPARATOR

Supervised exercise therapy by a physiotherapist

Other: Supervised Exercise Therapy

Interventions

The Percutaneous Transluminal Angioplasty (PTA) procedure will be performed by an experienced interventional radiologist using a conventional guide wire and balloon catheter technique. A stent will be placed in cases in which the residual mean pressure gradient is greater than 10 mmHg across the treated site or when more than 30% stenosis after the procedure is detected. All PTA patients are encouraged perform at least three walking sessions every day.

Also known as: Endovascular treatment
Intervention group: Angioplasty

Supervised Exercise Therapy (SET) will take place in the hospital or community based according to the guidelines of the Dutch Society for Physiotherapists. The duration of the treatment will be at least 6 months and with a frequency of 2 times a week for at least 60 minutes and an intensity near maximum pain barrier (defined as pain of which it is not possible to be distracted). The frequency of the training will decrease after 3 months and the patients will receive homework, make a plan and keep a log of their exercise activities. Furthermore the program consists of walking pattern improvement and enhancement of endurance and strength. All SET patients are encouraged to perform at least three walking sessions every day on their own.

Also known as: Conservative treatment
Control: Supervised Exercise Therapy

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18 years or older;
  • Disabling claudication as defined by surgeon based on patient's history;
  • Ankle/Brachial Index (ABI) \< 0.9 or drop in ABI \> 0.15 after exercise test;
  • Hemodynamic stenosis of the common or external iliac artery on Color Duplex Scanning (CDS) (PSV ratio ≥ 2.5 or EDV ≥ 0.6 m/s) or on Magnetic Resonance Angiography (MRA) or Computed Tomography Angiography (CTA)(\> 50% stenosis) or occlusion of the common or external iliac artery on CDS (PSV 0 m/s) or on MRA or CTA;
  • Iliac artery lesion and a concomitant stenosis in the superficial femoral artery defined as stenosis \> 50% by CDS (PSV ratio ≥ 2.5 or EDV ≥ 0.6 m/s) or on MRA or CTA, or occlusion on CDS (PSV 0 m/s) or MRA or CTA;
  • Lesion classified A, B or C according to the TASC (TransAtlantic Inter-Society Consensus) classification of aortoiliac lesions;
  • Patient is able to walk at least 2 minutes on a treadmill at 3.2 km/h and 10% incline;
  • The Maximum Walking Distance on a treadmill \< 300 meters.

You may not qualify if:

  • Life expectancy \< 3 months;
  • Patient is unable to complete self-reported questionnaires (insufficiently reading or speaking the Dutch language, cognitive disorders, etc);
  • Patient is unable to give informed consent;
  • A documented contrast allergy;
  • Pregnancy;
  • Contra-indication for anticoagulant therapy;
  • Duration of current complaints \< 3 months;
  • Occlusion of the common femoral artery at the affected side;
  • Patient participates in another study;
  • Heart failure or Angina Pectoris NYHA III or IV. (NYHA III: Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea; NYHA IV: Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased);
  • Patient previously received Supervised Exercise Therapy (SET) according to KNGF (Dutch Society for Physiotherapists) guidelines;
  • Renal insufficiency (serum creatinin \> 150 micromol/l).
