NCT00717639

Brief Summary

This study aims at investigating the diagnostic accuracy of magnetic resonance angiography using the contrast agent Vasovist® in the detection of relevant vascular narrowing of the lower extremity. Patients who have been scheduled for intra-arterial conventional angiography are eligible for this trial.

Outcome Measures

Primary Outcomes (1)

  • Accuracy of quantitative stenosis grading (<50%, >=50%) of Vasovist enhanced MRA with regard to i.a. DSA as standard of reference

    End of study (anticipated Sep 2009)

Secondary Outcomes (7)

  • Proportion of correct stenosis gradings (<50%, 50-99%, occlusion) of Vasovist® enhanced MRA compared to DSA

    End of study

  • Sensitivity and specificity (<50%, >=50%) of Vasovist enhanced MRA compared to DSA

    End of study

  • Length of stenosis (target) of Vasovist® enhanced MRA compared to DSA

    End of study

  • Correlation of the description of the inflow, target, outflow of Vasovist® enhanced MRA (combined) compared to DSA

    End of study

  • Diagnostic value (detection of target lesion y/n) of time-resolved first pass MRA in comparison to high-spatial resolution steady state MRA

    End of study

  • +2 more secondary outcomes

Study Arms (1)

1

EXPERIMENTAL

single arm study, all patients will undergo Vasovist-enhanced MRA

Procedure: Diagnostic MR-Angiography

Interventions

Single MR-Angiography of the lower extremity after the bolus injection 0.03mmol/kg BW Vasovist

Also known as: Vasovist(R), generic name - gadofosveset

Eligibility Criteria

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

You may qualify if:

  • Patients who have Fontaine-stage III and IV and an indication for therapeutic i.a. DSA
  • PAOD has to be confirmed by ECCM MRA, CTA, non-selective DSA, Doppler ultrasound (DUS) prior to the study.
  • Patients who are willing to undergo the study MRA procedure with Vasovist
  • Patients who are willing to comply with the study procedures (e.g. being followed-up for 12 hours after the Vasovist injection).
  • Patients who have given their fully informed and written consent voluntarily.

You may not qualify if:

  • Being less than 18 years of age.
  • Women who are pregnant, lactating or who are of childbearing potential and have not had a negative urine pregnancy test the same day as administration of Vasovist. The manufacturer's instructions for performing the urinary pregnancy test are to be followed.
  • Patients who are scheduled for any therapy between any of the two procedures (MRA and DSA) that interferes with the comparability of the two angiographic procedures.
  • Having an underlying disease or concomitant medication which may interfere with efficacy or safety evaluations as planned in this study.
  • Having any physical or mental status that interferes with the informed consent procedure including self-signed consent.
  • GFR \< 30 ml/m²/1.73m² (MDRD), values ≤ 1 week or patients on hemodialysis
  • Renal or liver transplant patients, including patients with scheduled liver transplant are excluded due to the potential risk for nephrogenic systemic fibrosis (NSF).
  • MR contraindications (pacemaker, magnetic clips, severe claustrophobia)
  • Known allergy to Gadofosveset
  • Presenting with history of anaphylactoid or anaphylactic reaction to any allergen including drugs and contrast agents.
  • Untreated significant stenosis in pelvis
  • Known severe coagulopathy (PTT \> 25s, Quick \< 60%)
  • Having received any investigational drug within 7 days prior to entering this study or who are planned to receive any investigational drug during the safety follow-up period.
  • Not being able to remain lying down for at least 30-45 min (e.g. patients with unstable angina, dyspnea at rest, severe pain at rest, severe back pain).
  • Being clinically unstable and whose clinical course during the 12 hours observation period is unpredictable.
  • +3 more criteria
