  1. Endovascular surgery based solely on noninvasive preprocedural imaging. Discussion.

    Article, Communication - En anglais

    Annual Meeting of the Eastern Vascular Society. Newport, RI, USA, 1998/05/01.


    Conventional pre-endovascular procedural evaluation uses both noninvasive testing and diagnostic arteriography.

    Diagnostic and therapeutic procedures often must be performed separately because of concerns about excessive contrast administration or inappropriate location of vascular access for the interventional procedure.

    We wanted to determine if patients could successfully undergo endovascular procedures based on noninvasive modalities alone.


    One hundred nineteen consecutive patients requiring intervention for lower-extremity ischemia were evaluated by means of physical examinations and segmental pressure measurements.

    Patients then underwent magnetic resonance angiography (MRA) to image native vessels or duplex scanning for failing bypass grafts.

    Suitable patients underwent endovascular procedures with « road map » arteriography, which was compared with preoperative duplex scanning or MRA findings.

    Costs of the conventional and noninvasive approaches were compared, on the basis of estimated hospital cost schedule.


    Sixty consecutive endovascular procedures were performed in 56 patients (105 lesions angioplastied), either alone (30,50%) or in combination (30,50%) with another vascular reconstruction.

    Completely noninvasive evaluation was accomplished in 43 procedures (72%), either by means of duplex scanning (11,18%) or MRA (32,53%). (...)
