“…While conventional CT can demonstrate an aneurysm, the artery of origin is not always clear. Three-dimensional spiral CT may allow a de®nitive diagnosis to be made prior to angiography in some cases (Figure 7) [6].…”

Hepatic artery aneurysms (HAAs) are rare. A review of the English language literature from 1985 to 1995 for reports of visceral artery aneurysms showed HAA to be the most frequently reported visceral aneurysm during that decade. This increase in incidence relates to the increasing use of percutaneous diagnostic and therapeutic procedures. A second factor is the increased use of diagnostic CT scanning after blunt liver trauma. The purpose of this pictorial review is to illustrate the imaging presentation and radiological management of HAAs.

“…The incidence of hepatic artery aneurysm follows that of the most common splenic artery. 5) Although this still remains an uncommon vascular complication, which was first reported by Wilson in 1819, the detection rate has improved more in the recent 20 years rather than the past ; this probably reflects the wide spread use of computed tomography(CT) scanning. 6) 80% of hepatic artery aneurysms are extrahepatic and 20% are intrahepatic.…”

Mycotic aneurysms of the hepatic artery are usually caused by mycotic infection in patients suffering with bacterial endocarditis. Mycotic aneurysms have become very rare recently due to early intensive antibiotic treatment for infective endocarditis. Despite of the non-specific symptoms, these aneurysms show a high possibility of sudden death if thye ruptured. Therefore, early detection and surgical repair of aneurysms are very important. We report here on a case of hepatic artery mycotic aneurysm that presented as sudden shock and rupture.

“…Advances in CT instrumentation also have increased the usefulness and safety of emergency CT. For example, the recently developed spiral or helical CT enables demonstration of 3D images of many organs [1, 3, 16, 17]. Concerning diagnosis in the vascular system, many reports have included 3D‐CT, another advantage of which is that 3D scans can be obtained during the vascular phase of a contrast‐enhanced study.…”

“…The advantage of this type of acquisition is its ability to acquire contiguous patient data, which eliminates the respiratory misregistration that frequently degrades the image quality of three‐dimensional (3D) displays and multiplanar re‐formations [1, 2]. Another merit of 3D‐CT is that the resultant 3D data set allows for retrospective re‐formation of structures in any projection [7, 3]. 3D‐CT has been useful in differentiating a structure from surrounding tissues by striking contrast, such as a bone or enhanced vessels.…”

Usefulness of the 3‐Dimensionally Reconstructed Computed Tomography Imaging for Diagnosis of the Site of Tracheal Injury (3D‐Tracheography)

et al. 2004

Computed tomography (CT) has not been considered useful for early diagnosis of traumatized patients who could hardly hold their breath, particularly patients with tracheal injuries. However, the recent development of spiral CT has made it possible to acquire contiguous patient data, which eliminates the respiratory misregistration. Air is easily differentiated from surrounding tissues by striking contrast, and the trachea can therefore be well displayed by three-dimensional (3D)-CT. We consider that it is possible to show tracheal injury by 3D-CT. The aim of this study is to clarify the usefulness of 3D-CT for detecting the injury site of blunt tracheal injuries. The study was carried out in hemodynamically stable patients who were suspected of having tracheal injury based on clinical manifestations such as hemoptysis, or cervical subcutaneous, deep cervical, or mediastinal emphysema. Repeated bronchoscopy confirmed tracheal injury. The virtual images of the 3D-CT (3D-tracheography) were compared with the direct images of bronchoscopic findings. Five cases were examined. In patients with tracheal injury, bronchoscopy revealed laceration of the tracheal lumen or disruption and dislocation of the tracheal cartilage, partially coated by mucus and clot, findings that confirmed the diagnosis of tracheal injury. The virtual images of the 3D-tracheography clearly showed the injury as a defect in the tracheal wall or a depression in the wall. The site and size of injury shown in the 3D-tracheography were comparable with those detected by bronchoscopy. We succeeded in detecting tracheal injuries by 3D-CT imaging, the virtual images of which were comparable with the bronchoscopic findings. 3D-tracheography is a useful method for diagnosing the site and form of tracheal injury in hemodynamically stable patients.
