Visceral and peripheral arterial pseudoaneurysms.
ABSTRACT OBJECTIVE: Pseudoaneurysms are not rare, and various conditions can cause a pseudoaneurysm in all the cardiovascular systems. In this article, we discuss and show images of pseudoaneurysms of various arteries caused by various conditions. CONCLUSION: CT, MRI, sonography, and angiography may all be valuable in the imaging workup of pseudoaneurysms. Knowledge of the various appearances of pseudoaneurysms and of the proper management is essential to prevent a catastrophic outcome in cases of pseudoaneurysm.

ABSTRACT: Digestive haemorrhage following supramesocolic abdominal surgery (cephalic duodenopancreatectomy, cholecystectomy, total oesogastrectomy) is a rare but serious complication, which can be life-threatening. Improvement in scanning techniques has made it possible to modify the diagnostic strategy and improve the therapeutic management of the patients. The aim of this iconographic review is to recall the causes of digestive haemorrhage following supramesocolic surgery and to illustrate the dominant role of tomodensitometry in diagnosing it and in planning and controlling the efficacy of endovascular treatment.03/2012; 93(3):e148-58.

ABSTRACT: Les hémorragies digestives après chirurgie abdominale sus-mésocolique (duodénopancréatectomie céphalique, cholécystectomie, œsogastrectomie totale) sont une complication rare mais grave qui menace le pronostic vital. L’amélioration des techniques scanographiques a permis une modification de la stratégie diagnostique et une amélioration de la prise en charge thérapeutique des patients. Le but de cette revue iconographique est de rappeler les causes d’hémorragie digestive après chirurgie sus-mésocolique et d’illustrer le rôle prépondérant de la tomodensitométrie dans leur diagnostic ainsi que dans la planification et le contrôle de l’efficacité d’un traitement endovasculaire.03/2012; 93(3):159–169.

ABSTRACT: To evaluate the incidence, management, and outcome of visceral artery aneurysms (VAA) over one decade. 233 patients with 253 VAA were analyzed according to location, diameter, aneurysm type, aetiology, rupture, management, and outcome. VAA were localized at the splenic artery, coeliac trunk, renal artery, hepatic artery, superior mesenteric artery, and other locations. The aetiology was degenerative, iatrogenic after medical procedures, connective tissue disease, and others. The rate of rupture was much higher in pseudoaneurysms than true aneurysms (76.3 % vs.3.1 %). Fifty-nine VAA were treated by intervention (n = 45) or surgery (n = 14). Interventions included embolization with coils or glue, covered stents, or combinations of these. Thirty-five cases with ruptured VAA were treated on an emergency basis. There was no difference in size between ruptured and non-ruptured VAA. After interventional treatment, the 30-day mortality was 6.7 % in ruptured VAA compared to no mortality in non-ruptured cases. Follow-up included CT and/or MRI after a mean period of 18.0 ± 26.8 months. The current status of the patient was obtained by a structured telephone survey. Pseudoaneurysms of visceral arteries have a high risk for rupture. Aneurysm size seems to be no reliable predictor for rupture. Interventional treatment is safe and effective for management of VAA. • Diagnosis of visceral artery aneurysms is increasing due to CT and MRI. • Diameter of visceral arterial aneurysms is no reliable predictor for rupture. • False aneurysms/pseudoaneurysms and symptomatic cases need emergency treatment. • Interventional treatment is safe and effective.European Radiology 02/2015; 25(7).
