The role of CT-Scanner in diagnosis of intraventricle hemorrhage SUMMARY Objective : To describe the feature of intraventricular hemorrhage (IVH) image in CT scanner and beginning describe some reasons related to IVH in adults. Methods: In a cross - sectional using quantitative methods, we chose 52 patients who definitive diagnosed IVH by CT scan in Bach Mai hospital from August/2014 to September/2015. Results: The most common location hematoma in primary parenchyma is hippocampal central gray (55.55%), the most common location of IVH is occipital horn ventricular, the more greater hematoma size, the more high risk of poor prognosis, the more higher level of IVH, the high risk of poor prognosis. In people over 50 years old, the most common causes of IVH is hypertension and hypertension coordinate with other causes (51%),while people under 50 years old, they usually caused by vascular abnormalities (30%), the main causes of thalamus lobe bleeding and hippocampal central gray bleeding is hypertension (25%), lobe of brain bleeding caused by aneurysm (42.86%). Conclusion: When patients are diagnosed stroke, they must be take CT scanner image immediately, when the results showed IVH image, they must be take cerebrovascular CT scanner with multiple array receiver, with intravenous injection of contrast dye to initially find the causes. Key words: CT scanner, intraventricular hemorrhage, cause.

SUMMARY A secondary postpartum hemorrhage may occur between 24 hours and 6 weeks after the birth. Secondary postpartum hemorrhage may be caused by endometritis, damage to an artery in caesarean, possible as a result of abscess from puerperal infection that causes damage to blood vessel. The urterine artery lesion is the most common, the internal pudental artery lesion is very rare. We report a case of a 36 year old patient, bleeding 12 days in postpartum due to damage to the internal pudendal artery, successful embolization of the internal pudendal artery. Keyword: Secondary postpartum hemorrhage, embolization, uterine artery, internal pudendal artery.

SUMMARRY Isolated superior mesenteric artery (SMA) dissection, with no other abnormality or aortic dissection, is unusual. Diagnosis base on the aid of Doppler and 64-slice multidetector CT. We report two cases of isolated spontaneous SMA dissection without aortic involvement in two patients who had presented with epigastric pain that was especially worse after food intake. Examen on 64-slice multidetector CT show an isolated SMA dissection, not involving the aorta. These patients were managed conservatively with anticoagulants. Keyword: Isolated superior mesenteric artery.

Assessement changing in haemodynamics and contrast enhancement pattern of lung cancer lesions on perfusion CT SUMMARY Introduction : Lung tumour perfusion CT may help to evaluate characteristics and haemodynamics of lung cancer. This research was carried out to assess changes in haemodynamics and contrast enhancement pattern of lung cancer lesions. Methods: 12 patients were enrolled to the study underwent perfusion CT of lung tumour. Perfusion paramerters were obtained from perfusion CT maps. Results: perfusion paramerters increased in malignant tumour with measured blood flow of 33.15 ±15.7 ml/100g/min, blood volume of 17ml/100g and tumour volume ranged from 7 – 577ml. blood volume in small tumours was higher than that in larger lesions. The higher homogeneity in blood flow was found in small tumours. Conclusion : Lung tumour perfusion CT could be used to assess changes in tumour haemodynamics that may help in pretreatment of unresectable lung cancers. Keyword: Lung cancer, perfusion.

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 : 32 cases were diagnosed as testicular torsion, diagnosis after surgery is correct 100% of the cases. The mean age 19,2 ± 5,1. Sign “whirlpool” is found in 75% of cases, the common position is above the testicles 91.7%. Sign of losing the pulse signal at testicular torsion 31/32 (96.9%). Increased testicular size 27/32 (84.4%). 28/32 heterogeneous parenchyma, normal 3/32, 1/32 hypoechoic. Epididymis morphology change 25/32 cases (78.1%), of which the most common are sphere 76%. Conclusions: Triplex Ultrasonography has value in the different diagnosis of testicular torsion with other diseases causing scrotal pain. Keywords : Triplex sonography, testicular torsion.

In this number: 25% limbs with heaviest stage in rest pain, 61.36% in minor tissue loss and 13,64 % in major tissue loss. In 264 arteries: 46.05% with stenosis < 50% and 26.14% total stenosis with ≥ ½ in length. In 129 arteries with stenosis ≥ degree of 3: 28.68% belong to dorsal pedis artery, 48.06% branches from posterior tibial artery, 23.26% branches from peroneal arteries. The correlation coefficient r and significance p between foot arterial lesion and the level of critical foot ischemia, respectively: r from 0.755 to 0.891, all significance p <0.001.
