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.

    • "Gluteal artery aneurysms are found to be more common on the left side with a male predominance. These lesions are considered as an emergency as they are liable to rupture at any time with life-threatening hemorrhage.[910] "

    ABSTRACT: Aneurysms of the gluteal arteries are very rare with the majority being post-trauma pseudoaneurysms. Generally, management of these aneurysms could be surgical or through endovascular techniques. We present a case of a superior gluteal artery pseudoaneurysm complicating a pelvic fracture that presented as a gluteal mass. It was successfully treated by transcatheter coil embolization. We review the presentation, imaging, and treatment options. Aneurysms have to be considered in the differential diagnosis of soft tissue masses, therefore lesion intervention by aspiration or needle biopsy should not be tried before ruling out a possible vascular nature which will easily be revealed by ultrasound Doppler or computed tomography scans.

    • "Pseudoaneurysms are defined as a defect through the wall of a blood vessel, including the adventitial layer, causing a localized dilatation [3, 4]. The wall of a pseudoaneurysm is usually comprised of perivascular tissue, thrombus, and reactive fibrosis [5]. Etiologies for pseudoaneurysm formation include trauma, infection, and connective tissue disease [6, 7]. "

    ABSTRACT: Background. Although rare, visceral artery pseudoaneurysms often present as surgical emergencies with a specific mortality rate as high as 35% related to aneurysmal rupture. Risk factors for the development of iatrogenic pseudoaneurysms include anticoagulation, female gender, obesity, and vessel calcification. Case Report. We present a case of an elderly female who developed a dissecting pseudoaneurysm of the proper hepatic artery after undergoing routine surgery to resect a large duodenal adenoma. Surgical repair comprised of resection and primary anastomosis was employed resulting in a favourable outcome. Discussion/Conclusion. Surgical management reduces the risk of hepatic ischemia, biliary complications, and abscess formation. Although stenting, coil embolization, and thrombin injection are all plausible options for management, we propose that surgical reconstruction be considered seriously as a treatment for such spontaneous pseudoaneurysms.

    • "), so that the origin of the bleeding can be located [13] [14]. Certain haemorrhages are only revealed in the portal, or even delayed phase, so that a second helical scan needs to be done in the portal phase or even in the delayed phase, at the request of the radiologist at the acquisition console after reading the initial images directly.

    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.
