    Notes: Abstract Nineteen aneurysmal bone cysts and five angiomas of bone were treated by selective arterial embolization. The median follow-up was 22 months. In 17 patients healing occurred with complete relief of symptoms; in 11 of these almost complete ossification of the lesion resulted. In the remaining cases, little or no ossification was apparent but ossification may take 1 year or more to occur. No recurrence was observed in any of these cases. Recurrence occurred only in two cases. In one, growth of the recurrence stopped after a second embolization, and the X-rays showed no change. Selective arterial embolization represents a treatment of choice in aneurysmal bone cyst and angioma of bone especially of the spine, sacrum, or pelvis. In these sites embolization replaces surgery which might be hazardous due to intraoperative bleeding.

    Notes: Abstract Arterial embolization was performed in 36 patients with tumors of bone and soft tissue. Embolization was the only treatment in seven patients with benign lesions. Fourteen patients underwent embolization before surgery to obtain hemostasis and/or reduce tumor size. Fifteen patients with inoperable primary bone tumors or skeletal metastases underwent palliative embolization. The best results were obtained in aneurysmal bone cysts.

    Description / Table of Contents: Résumé Une étude angiographique a permis d'étudier les variations du nombre, de l'origine, du trajet et des anastomoses des artères du pancréas ainsi que leur diamètre moyen en fonction des groupes d'âges (20–40, 40–60 et plus de 60 ans); cette étude quantitative a été effectuée par artériographie cœliaque sélective chez 72 patients ne présentant aucune lésion pancréatique. Les différentes artères du pancréas ont bien été visualisées dans la majorité des cas, excepté l'arcade pancréatico-duodénale inférieure qui est mal explorée par l'angiographie cœliaque. Ce travail confirme les grandes variations d'origine et d'anastomoses des artères pancréatiques transverse (artère pancréatique inférieure) et dorsale et permet de proposer des explications embryologiques et des applications cliniques. De plus, un pourcentage important d'artères multiples (4 ou plus) et d'artères de la queue du pancréas a été noté, permettant d'évoquer le rôle fonctionnel de cette distribution particulière. Enfin il n'a pas été trouvé de différence significative du diamètre des artères en fonction de l'âge, ce qui est probablement dû au maintien d'un contrôle nerveux périvasculaire réflexe des vaisseaux pancréatiques chez les sujets âgés. La méthode angiographique a une sensibilité satisfaisante qui permet une bonne visualisation des artères du pancréas et de leurs anastomoses in vivo.
    Notes: Summary The angiographic visualization of the pancreatic arteries, their numerical variations, origins, course and anastomoses, as well as their mean diameter by age-group (20–40, 41–60, 〉60 years) have been quantitatively investigated by selective celiac angiography in 72 patients without pancreatic disease. Visualization of the various arteries was achieved in a high percentage of cases except for the inferior pancreaticoduodenal arches, due to undervaluation of this vessel by celiac angiography. Confirmation of the great variability of the origin and anastomoses of the dorsal and transverse pancreatic arteries was obtained and possible embryologic reasons and clinical implications of this fact are discussed. Furthermore, a high percentage of multiple (quadruple or more) pancreatica magna and caudae pancreatis arteries has been observed and a functional role of this peculiar arrangement is suggested, Finally, no statistically significant differences were found in the diameter of any artery due to increasing age probably reflecting maintained neural perivascular control of the pancreatic vessels in the elderly. Satisfactory sensitivity of the angiographic method has been found with respect to the evaluation of visualization and anastomoses of the pancreatic arteries in vivo.

    Description / Table of Contents: Résumé Une étude angiographique quantitative de l'origine et du diamètre moyen des artères de la surrénale a été réalisée à partir de 100 aortographies effectuées chez des sujets indemnes de lésions surrénaliennes, séparés en 2 tranches d'âge: 20–40 et 41–60 ans. La mise en évidence des différentes artères a été obtenue avec un pourcentage sensiblement comparable aux données de la littérature anatomique classique, en tenant compte cependant d'une visualisation moyenne des a. surrénales moyennes. Les variations d'origine concernent tout particulièrement les a. surrénales supérieures et moyennes, amenant à discuter les explications embryologiques et les implications cliniques de ces variations. Des différences statistiquement significatives du diamètre moyen de chaque artère ont été notées sur l'ensemble des sujets examinés confirmant le concept de territoires vasculaires d'origine diverse; des variations liées à l'âge ont été observées au niveau de l'a. surrénale moyenne, suggérant le rôle principal que jouerait ce vaisseau dans les adaptations physiologiques de la vascularisation de la glande surrénale au vieillissement.
    Notes: Summary The angiographic visualization, arterial origin and mean diameter per age group (20–40, 41–60 years) of the suprarenal arterial vessels have been quantitatively investigated by aortography in 100 patients without suprarenal disease. Visualization of the various arteries was achieved in a percentage substantially comparable to the anatomic data of the literature, though with lower detection of the superior suprarenal vessels. A variable site of origin was present particularly for the superior and middle suprarenal vessels compared to the inferior suprarenal arteries and possible embryological reasons and clinical implications are discussed. Statistically significant differences were found in the mean diameter of each arterial vessel in all the subjects examined, thus substantiating the concept of differential arterial supply to various portions of the gland. Age-related changes were demonstrated in the right middle suprarenal artery, suggesting a predominant role of this vessel in the physiological adaptation of the blood supply to the gland with increasing age.
