Aims and objectives
The first experimental and clinical study on endovascular aneurysms repair (EVAR) of abdominal aorta (AA),
was published by JC Parodi et al in 1991 .
initially addressed only to patients at high anesthetic risk and therefore not suitable to "open treatment",
currently is broadly used [2,3,4]. Various anatomical parameters concerning aortic neck,
iliac and collateral aortic arteries must be evaluated to determinate patients suitability to EVAR and to choose the...
Methods and materials
This is a retrospective study conducted in a 19-months period (September 2013 - April 2015).
Patients with certain diagnosis of aneurysm of AA,
coming to our Center to be treated,
We excluded Patients suitable for open treatment and those who had contraindications to MRI (presence of metallic devices or claustrophobia). Written informed consentwas obtained fromallpatients who underwent preoperative NC-MRI.
Thirty patients were recruited: 27 men with mean age of 72.4 (range...
Nonenhanced MRI was performed successfully in all patients and the retrospective planning for EVAR was feasible in all cases. ANATOMIC MEASUREMENTS Artifacts - even if one patient had bilateral hip arthroplasty,
two patients had iliac stents and another one had renal artery stent - did not hamper measurements in any case. Interobserver ICCs were calculated for all single measures and they are summarized in Tab.1a (for CTA) – b (for NC-MRI) and Fig.
4; intermodality ICCs – also calculated...
our study shows that NC-MR is a reliable alternative to CTA for EVAR planning.
Actually CTA remains the standard of reference; however,
in patients with renal impairment – to whom iodinated and paramagnetic contrast medium cannot be administered – the employment of NC-MR can be suggested,
because it allows accurate measurements of anatomic structures for preoperative planning.
