Role of abdominal computed tomography in diagnosis of adult intussception SUMMARY Objective: To describe imaging characteristics of adult intussception (AI) on CT and to identify diagnostic values of them. Materials and methods : Case series report including patients: defined AI on CT, over 18 years of age, having been on surgery, with/ without histo-pathology. Patients are divided into two groups: those with enteroenteric intussusception (EI) and those with intussusceptions involving colon (IC), including enterocolic and colocolic lesions. Results: from 01/2014 to 01/2017 at University Medical Center, HCMC, there were 53 intussusceptions of 52 patients on CT (EI: 14_26%, IC: 39_74%). 33 of those have intussusception on surgery (EI: 10_3%, IC: 23_70%). Mean length of intussusceptions of both groups is 7,6±4,0cm (2,4-19,6). Mean diameter of intussusceptions is 4,7±1,1cm (2,2-7). Mean interposed fat thickness is 1±0,6cm (0,1-2,6). CT and surgery characteristics of patients in EI group are of minor differences. Ratio of AI on CT with obstruction and with ischemia_necrosis are both 3,8%. Outcome of diagnosing complications by CT and by surgery are comparable. Characteristics capable of predicting presence of insstususception on surgery are: in EI group: lead point, length > 6cm, interposed fat thickness > 0,5 cm; in IC group: length > 5.65 cm, interposed fat thickness > 0,75 cm. Conclusion: Characteristics capable of predicting presence of insstususception on surgery are: lead point, length, interposed fat thickness. Key words: Computerized Tomography (CT), Intussusception, obstruction, enteric ischemia, lead point.

Interventional Radiology in Cancer-related Pain Management SUMMARY Pain is a clinical symptom affecting the life quality in patients with cancer. Pain can be induced from different sources; therefore, pain management is also varied following pain mechanisms. Apart from traditional pain care therapies, interventional radiology may help in managing pain with minimal invasive techniques. This review focuses on imaging guided pain management methods used in patients with severe pain in advanced cancer stages when traditional pain control shown ineffective. Key word: Interventional Radiology, Pain management, Cancer.

Bronchial artery charateristics and patient outcome in patients with acute hemoptysis treated using dual embo-agents SUMMARY Objectives : This study was carried out to describe angiographic charateristics and patient outcome in patients with acute hemoptysis treated using dual embo-agents Methods: 28 patients with acute hemoptysis were included in this study. All abnormal vessels were occluded using microsphere then re-enforced with N-butyl cyanoacrylate (NBCA). Patients were followed-up one year from procedure date. Results: Technical success rate accounted for 96.4%. Almost all patients presented with bronchial artery dilatation while 46% of patients had abnormal feeding vessels arising from subclavian artery, 39% from intercostal arteries. Postprocedural complications included chest pain (4 cases, 14.3%), infection (1 patient, 3.6%), unexpected vessel occlusion (1 case, 3.6%) and bronchial artery dissection (1 subject, 3.6%). Recurrent rate calculated in one year of following up was 7.14%. Conclusion: Major angiographic abnormalities were dilatation of the bronchial artery to lung lesions and its colaterals. Dual-material embolization is an effective treatment method with significantly high rate of technial and clinical success. Keyword : Hemoptysis, bronchial artery, embolization.

Evaluation the effectiveness of arterial embolization in the treatment of maxillofacial trauma SUMMARY Purpose: This study was designed to characterize image of vascular lesions on DSA and evaluate the effectiveness of arterial embolization in the treatment of maxillofacial trauma. Materials and Methods: 44 patients with bleeding after jaw injury, did not meet with the local hemostatic measures who were taken to the angiography for embolization from April 2011 to September 2015. Results: 13.6% of the internal carotid artery injury with 4.5% of dissection and 9.1% of carotid-cavernous sinus fistula. 90,1% of the external carotid artery injury, the (internal) maxillary artery is the most vulnerable (in 88.6%) that the maxillary artery injury merely in 56.8% or combination in 31.8%. The external carotid artery injury of a side in 59.1%, 40.9% of two side. Active bleeding is the most common of injury morphology (88,6,6%), with 63.6% merely, and associated with other forms 25%, (pseudoaneurysms, arteriovenous malformation, the internal carotid artery injury), pseudoaneurysm merely is a rare lesions in 2.3%. Hystoacryl is the most common embolization material (86.3%), 59.1% of Hystoacryl merely and coordinate 13.6%. PVA embolization merely in 13.6%; Spongel in 13.6%; no circumstances used to try Coil. Technical success was 95.4%, 4.6% failed. Successful hemostasis was achieved in 95.4% after the first intervention and 100% after 2nd intervention. Clinical success was achieved in 79.6%. Clinical non-success included 7 patients died of severe traumatic brain injury (15.9%) and 2 patients (4.5%) had complications, including 1 patient with face necrosis and 1 patient with tongue necrosis. Conclusion : Arterial Embolization in the Treatment of Maxillofacial Trauma was effective and quick to control bleeding. Keywords: bleeding, maxillofacial trauma, Embolization.

Results of endovascular treatment of posterior fossa intracranial aneuryms SUMMARY Purpose : To evaluate the results of endovascular treatment of posterior fossa intracanial aneuryms. Method and materials: Fourty one patients harboring fourty five posterior fossa intracranial aneuryms were treated by endovascular therapy from 2012 to 2015 at Bach Mai Hospital. Clinical outcomes and follow-up of aneurysm occlusion’s result were classified by modified Rankin Scale and on MRI imaging. Results: Twenty eight patients presented subaranoidien hemorrhage and thirteen patients without SAH. Different technics were used such as coiling embolization (44.4%), coiling with balloon remodeling technics (22.2%), coiling with stenting (2.3%), flow-diverter stenting (6.7%) and parent artery occlusion (24.4%). The rate of complete aneurysm occlusion, neck residue and partial occlusion were 80%; 11.1% and 8.9% respectively. Result of good outcomes (mRS 0-2) was 85.4% and mortality was 12.2%. Almost of aneurysms post treatment were stability (84.6%), only 15,4% aneurysm were slight recanalization. The hospitalization duration of unruptured and ruptured aneurysm were 9.3 and 17.8 days, respectively. Conclusion: Endovascular treatment of posterior circulation aneurysms showed efficace of clinical outcome and stability with low morbility and mortality. Keywords: Aneurysm, posterior circulation aneurysm, embolization.

The preliminary result of endovascular treatment in spinal vascular malformation SUMMARY Objective : To evaluate the preliminary result of endovascular treatment in spinal vascular malformation. Material and method: We prospectively studied patients with spinal arteriovenous shunt who were diagnosed and endovascular treatement with spinal arteriovenous shunt at Bach Mai hospital from 2012 to 2013. Clinical features were analyzed before and after treatment by Aminoff-Logue disability scale. MR imaging characteristics were evaluated. Result: 9 patients were treated by endovascular embolization, 44.4% were spinal arteriovenous malformation, 55.6% were spinal dural arteriovenous fistulae. MRI studies showed intramedullary increased T2 signal and dilated venous drainage in all patients. The rate of complete angiographic obliteration was 55.5% and nearly occluded in 45.5 . After follow up of 3 months, clinically significance improvement was achieved in 66.7%, partial recovery in 22.2%. Conclusion: n-BCA glue embolization for spinal arteriovenous shunt should be considered the treatment of choice with satisfactory outcomes. Large studies with longer follow-up are required to determinate the safety and efficacy of endovascular treatment.
