Mycotic hepatic artery aneurysms (HAAs) have become very rare due to antibiotics. Untreated, they have a high possibility of rupture and mortality. In this paper, on the case of a 67-year-old male who had severe right-upper-quadrant abdominal pain and a history of infective endocarditis is reported. The computed tomography (CT) and arterial angiography findings led to a diagnosis of a ruptured mycotic HAA. The CT showed an HAA and the formation of an intrahepatic hematoma caused by aneurysmal rupture. The arterial angiography showed a mycotic HAA that arose from the right posterior hepatic artery. Percutaneous transcatheter arterial embolization was used to successfully treat the HAA. Since then, the patient has been doing well, without symptoms.

Purpose: This study was to evaluate the effect of arterial embolization on survival in patients with pelvic bone fractures and arterial bleeding. Methods: From January 2001 to December 2007, in all, 18 patients with pelvic bone fractures that had been treated with interventional arterial embolization were included in this retrospective study. The Injury Severity Score (ISS), the Revised Trauma Score (RTS), the initial hemodynamic status, the blood gas analysis, blood transfusion data, and mortality were the main outcome measurements. Results: Pelvic bone fractures were classified into lateral compression (LC), antero-posterior compression (APC), vertical shear (VS), and combined (CM) type according to the Young-Burgess classification. The Survivor group included 11 patients (61.1%), and the non-survivor group included 7 patients (38.9%). The mean ages for the survivor and the non-survivor groups were 40.0 and 45.6 years (p=0.517). The types of pelvic bone fractures were LC 11 (61.1%), APC 6 (33.3%), and VS 1 (5.6%): LC 7 (63.6%), and APC 4 (36.4%) in the survivor group and LC 4 (57.1%), APC 2 (28.6%), and VS 1 (14.3%) in the non-survivor group. The internal iliac artery was the predominant injured vessel among both the survivors (n = 5, 45.5%) and the non-survivors (n = 4, 57.1%). No differences in initial blood pressures, ISS, and RTS existed between the two groups, but the arterial pH was lower in the non-survivor group (pH 7.09 (${\pm}0.20$) vs 7.30 (${\pm}0.08$), p=0.018). The number of transfused 24-hour units of packed RBC was greater in the non-survivor group ($24.1{\pm}12.5$ vs $14.4{\pm}6.8$, p=0.046). Conclusion: No differences in initial blood pressure and trauma scores existed between survivors and non-survivors with pelvic bone fractures, who had been treated with arterial embolization, but arterial pH was lower the in non-survivors.

Simultaneous subarachnoid hemorrhage and infarction is a quite rare presentation in a patient with a spontaneous dissecting aneurysm of the anterior cerebral artery. Identifying relevant radiographic features and serial angiographic surveillance as well as mode of clinical manifestation, either hemorrhage or infarction, could sufficiently determine appropriate treatment. Enlargement of ruptured aneurysm and progressing arterial stenosis around the aneurysm indicates impending risk of subsequent stroke. In this setting, prompt treatment with stent-assisted endovascular embolization can be a reliable alternative to direct surgery. When multiple arterial dissections are coexistent, management strategy often became complicated. However, satisfactory clinical results can be obtained by acknowledging responsible arterial site with careful radiographic inspection and antiplatelet medication.

Objective: To investigate liver fibrosis, TGF-${\beta}1$ levels and curative effects on hepatocellular carcinoma (HCC) with small and conventional dose perfusion chemotherapy by transcatheter arterial chemo embolization (TACE). Methods: Thirty-six hepatocellular carcinoma patients not indicated for surgical resection underwent super-selective transcatheter arterial chemoembolization, divided into small dose (n=15) and conventional dose (n=21) chemotherapy groups. Results: With conventional doses, four indices of liver fibrosis focusing on hyaluronate acide (HA), human procollagen type-III (hPC-III), collagen type-Ⅳ (Ⅳ-C) and transforming growth factor-${\beta}l$ (TGF-${\beta}1$) were obviously increased postoperative compared with preoperative (P<0.01); in contrast, with small doses there were no significant differences except for TGF-${\beta}1$. Five year survival demonstrated no significant differences between the two groups (P>0.05). Conclusion: To hepatocellular carcinoma patients treated by TACE, reducing doses of chemotherapy drugs can reduce progress of liver fibrosis, without impacting on five year survival.

Purpose: The purpose of this study was to determine the essential factors for prompt arrangement of angio-embolization in patients with pelvic ring fractures. Methods: A total of 62 patients with pelvic ring fractures who underwent angio-embolization in Dankook University Hospital from March 2013 to June 2018 were retrospectively reviewed. There were 38 men and 24 women with a mean age of 59.8 years. The types of pelvic ring fractures were categorized according to the Tile classification. Patient variables included sex, initial hemoglobin concentration, initial systolic blood pressure, transfused packed red blood cells within 24 hours, Injury Severity Score (ISS), mortality rate, length of hospital stay, and time to angio-embolization. Results: The most common pelvic fracture pattern was Tile type B (n=34, 54.8%). The mean ISS was $27.3{\pm}10.9$ with 50% having an $ISS{\geq}25$. The mean time to angio-embolization from arrival was $173.6{\pm}89minutes$. Type B ($180.1{\pm}72.3minutes$) and type C fractures ($174.7{\pm}91.3minutes$) required more time to angio-embolization than type A fractures ($156.6{\pm}123minutes$). True arterial bleeding was identified in types A (35.7%), B (64.7%), and C (71.4%). Conclusions: It is important to save time to reach the angio-embolization room in treating patients with pelvic bone fractures. Trauma surgeons need to consider prompt arrangement of angio-embolization when encountering Tile type B or C pelvic fractures due to the high risk of true arterial bleeding.

Massive and untreated hemoptysis is associated with a mortality of greater than 50 percents. Since the bleeding was from a bronchial arterial source in the vast majority of patients, embolization of the bronchial arteries has become an accepted treatment in the management of massive hemoptysis because it achieves immediate control of the patients. We have controlled massive hemoptysis in a case with selective bronchial arteral embolization with Gelfoam.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

Purpose: Bleeding is the primary cause of death after severe pelvic fracture. Transcatheter arterial embolization (TAE) is the mainstay of treatment for arterial bleeding. This study aimed to determine the frequency of bleeding by angiography of blush-positive pelvic fractures on computed tomography (CT) images. The bleeding arteries that were involved were investigated by pelvic angiography. Methods: This retrospective cohort study evaluated 83 pelvic fracture patients who were treated in the intensive care unit of the author's trauma center between January 01, 2013 and April 30, 2015. Results: Overall mortality was 9 of 83 patients (10.8%). Blush was observed in 37 patients; blush-positive patients had significantly higher mortality (24.3%) than blush-negative patients (0%). Twenty-four of the 83 patients (28.9%) underwent pelvic angiography. Bleeding was showed in 22 of 24 patients in pelvic angiography. TAE was successfully performed in 21 (95.5%) of the bleeding 22 patients. Angiography was performed in 23 of 37 blush-positive patients, and arterial bleeding was identified in 21 (91.3%). A total 33 bleeding arteries were identified in 22 angiography-positive patients. The most frequent origin of bleeding was internal iliac artery (69.7%) followed by the external iliac artery (18.2%) and lumbar arteries (12.1%). Conclusion: The vascular blush observed in CT scans indicates sites of ongoing bleeding in pelvic angiography. TAE is an excellent therapeutic option for arterial bleeding and has a high success rate with few complications.
