dc.description.abstractPurpose: The prevalence of the celiac artery stenosis caused by median arcuate ligament (MAL) compression and its multidetector computed tomography (MDCT) characteristics were evaluated in patients who underwent abdominal MDCT procedures, retrospectively. Methods: Totally 1121 patients who had abdominal MDCT with arterial phase or MDCT angiography of the abdominal aorta for various indications were analyzed for celiac artery compression by the MAL. Results: Fifty (ie, 4.6%) patients showed typical MDCT features of MAL compression. Focal narrowing of the proximal celiac artery, a characteristic hooked appearance of the narrowed segment without calcification and atherosclerotic changes were diagnostic. Poststenotic dilatation was detected in 22 (44%) patients with MAL compression. The ratio of the stenosis of the celiac artery was between 35%-50% in 15 patients and 51%-80% in 35 patients. The gastroduodenal artery diameter of these patients was not significantly different from the asymptomatic control group. Conclusion: MALS is an uncommon entity but it should be kept in mind in the presence of unexplained gastrointestinal symptoms. MDCT is a minimally invasive and plays a dominant role in the diagnosis of MAL compression especially with reformatted and 3-D reconstructed images.
dc.description.abstractObjet : Nous avons evalu e, de fac¸on r etrospective, le taux de pr evalence de la st enose du tronc cœliaque attribuable a une compression par le ligament arqu e m edian et les caract eristiques observ ees par tomodensitom etrie multibarrettes (TDM multibarrettes) chez des patients ayant subi des techniques d’imagerie abdominale par TDM multibarrettes. M ethodes : Au total, nous avons analys e le dossier de 1 121 patients ayant subi une TDM multibarrettes abdominale avec acquisition a la phase art erielle ou une angiographie par TDM multibarrettes de l’aorte abdominale pour divers motifs afin de d eceler une compression du tronc cœliaque par le ligament arqu e m edian. R esultats : Des caract eristiques evoquant une compression par le ligament arqu e m edian ont et e observ ees par TDM multibarrettes chez 50 patients (soit 4,6 % des patients). Le r etr ecissement focal de la partie proximale du tronc cœliaque, l’aspect recourb e caract eristique de ce tronc¸on et l’absence de calcification et de modifications ath eroscl ereuses ont permis d’ etablir le diagnostic. Une dilatation post-st enotique a et e d ecel ee chez 22 des 50 patients (44 %) qui pr esentaient une compression par le ligament arqu e m edian. Le degr e de st enose du tronc cœliaque etait de 35 a 50 % chez 15 patients, et de 51 a 80 % chez 35 patients. Chez ces patients, le diametre de l’artere gastroduod enale ne diff erait pas sur le plan statistique de celui du groupe t emoin asymptomatique. Conclusion : Le syndrome du ligament arqu e m edian n’est pas courant, mais il doit ^etre pris en consid eration en pr esence de sympt^omes gastro-intestinaux inexplicables. La TDM multibarrettes est une technique peu effractive et de premier plan pour etablir un diagnostic de compression du tronc cœliaque par le ligament arqu e m edian, notamment avec des techniques de reformatage et de reconstruction tridimensionnelle des images.
