“…Operative mortality for elective repair is 3%-5% but rises significantly in the presence of comorbid illnesses and previous abdominal surgery [1][2][3][4]. Transfemoral endoluminal exclusion of AAA with stent-mounted grafts has become an alternative for selected patients with the appropriate anatomy [5].…”

The objective of the study was to determine if uncovered self-expanding metallic stents with or without polyester-covered coils can exclude abdominal aortic aneurysms (AAA). Exclusion using uncovered metal stents with or without coils has been shown to be successful in the animal model. Twelve patients underwent aneurysmal therapy with uncovered self-expanding metallic stents and polyester covered metallic coils (male, 8; female, 4; mean age, 74 +/- 8 years) because no other therapeutic alternative was available. Indications were severe aorto-iliac disease, presumptively high surgical risk due to comorbidities, a previously failed endograft attempt, and a hostile abdomen as a result of prior surgeries. Under local anesthesia, stents were introduced percutaneously via 10 or 11 Fr sheaths into the femoral artery and deployed in an overlapping fashion to cover the length of the AAA. All endoluminal procedures were successful, and no major complications were encountered. The average hospital stay was 33 +/- 21 hr. At a mean follow-up of 18 +/- 13 months, there was no rupture, leak, or evidence of aneurysm expansion in any of the patients. There was one mortality that was not AAA-related. The remaining patients had no aneurysm-related symptoms. Endoluminal exclusion of an AAA using self-expanding bare metal stents with or without coil embolization may be a viable treatment option for patients who cannot undergo standard surgical or endovascular repair. However, these data do not demonstrate that this methodology actually precludes rupture since the cohort is of small size. Cathet Cardiovasc Intervent 2001;54:12-18.

The development of radiological equipment such as MDCT or ultrasonography has increased the diagnostic accuracy of aortic aneurysms and has allowed for improvements in surgical and interventional treatment techniques. However, the mortality and morbidity rate of aortic aneurysms has not decreased significantly. For this reason, there is continuous interest in radiological evaluations of aortic aneurysms. This report reviews the radiological image findings and useful indications for both the diagnosis and surveillance of aortic aneurysms. The popular radiological features of an aortic aneurysm are aortic expansion, combined atherosclerosis, intraluminal mural thrombus, perianeurysmal inflammation and fibrosis, and perianeurysmal hemorrhage due to rupture. As rupture is the most important complication of an aortic aneurysm, various signs of an impending rupture have been suggested. These include the following: a maximum aneurysmal diameter larger than the threshold value, a high expansion rate, periaortic sentinel hemorrhage, and a hyperattenuating crescent in the mural thrombus or aneurysmal wall. To acknowledge the impending rupture of an aortic aneurysm, careful depiction of the clues is indispensable. (Korean Circulation J 2007;37:337-347)

Traumatic vessel injury can cause bleeding, thrombosis, embolization, or malperfusion due to external compression and spasm. Non-traumatic causes of acute large arterial emergencies include rupture of an aneurysm and pseudoaneurysm, dissection, embolization, and thrombosis in hypercoagulability syndromes. Ultrasonography is, of course, the imaging modality of choice in emergency cases; however, in central vascular injuries, spiral CT with contrast enhancement is the imaging modality that provides the most information. Angiography may be necessary for detailed information and before intervention. Stent-grafts are used to close large vascular lacerations, ruptured aortic aneurysms, and the entry tear of dissections. Interventional radiology methods play a major role in managing vascular emergencies.
