SUMMARY Objective: to apply and estimate the efficacy of embolization in non traumatic visceral arterial pseudoaneurysm. Subject and method: Twenty-seven patients underwent angiography and embolization at Bachmai hospital from 7/2020 to 7/2022. Result: In 27 patients (20 males & 07 females), 09 patients show extravasation in DSA. The splenic artery and the superior mesenteric artery are the arteries most commonly with visceral arterial pseudoaneurysms. Of the 27 patients studied, 24 had technical success in the first intervention, one required secondary intervention because of rebleeding and it was successfully treated by reintervention, one required ileectomy after embolisation due to ongoing hemorrhage, one patient died from uncontrolled blood transfusion shock. Conclusion: In hemodynamically stable and controlled patients, selective and super selective embolization is a safe and effective method for managing non traumatic visceral arterial pseudoaneurysm. Keywords: Visceral arterial pseudoaneurysm (VAPA), embolization, extravasation.

SUMMARY Objective: To determine the value of Diffusion-weighted imaging in distinguishing typical and atypical meningiomas. Subjects and methods: The study was performed at Choray Hospital from January 2021 to August 2022, with 66 typical and atypical meningiomas patients. The descriptive retrospective cross-sectional study was performed. Compare the tumor's signal intensity and mean ADC value with the histopathological results to distinguish typical and atypical meningiomas. Results: In 66 patients, there were 13(19.7%) male patients and 53(80.3%) female patients. The mean age of patients was 60.53 years old. The number of typical and atypical meningiomas cases was 43 (65.2%) and 23 (34.8%). There was no significant signal intensity difference between typical and atypical meningiomas (p=0.56). The mean ADC value for typical meningiomas is 0.843x10-3mm2/s and atypical is 0.737x103mm2/s, the difference is statistically significant with p=0.003. On the ROC curve, with an ADC cutoff of 0.780x10-3mm2/s, DWI can distinguish typical and atypical meningioma with sensitivity, specificity, PPV, NPV, and accuracy is 83.8%, 51.7%, 67.4%, 71.4%, 66.6% respectively. Conclusion: The mean ADC value of typical meningiomas is higher than that of atypical meningiomas. DWI is valuable in the differential diagnosis of typical and atypical meningiomas. Keywords: meningiomas, typical, atypical, diffusion-weighted imaging, ADC.

SUMMARY Placenta acrreta spectrum is a condition in which the placenta partially or completely invades and cannot be separated from the uterus muscle. Placenta previa is a condition in which the placenta partially or completely covers the cervix. Both phenomena increase the risk of postpartum haemorrhage, hemostasis disorders, and threaten the life of the mother and the fetus. Combine of the two phenomena increase blood loss in cesarean delivery as well as postpartum period, and is a great challenge required multidisciplinary for successful management. Prophylactic endovascular intervention is a minimally invasive treatment method, which plays an important role in prevent haemorrhage in the management of placenta accreta spectrum. This report describes a case of placenta percreta combine with placenta previa, which received prophylactic endovascular intervention using balloon occlusion of internal illiacs and uterine arteries embolization and underwent a cesarean delivery at 36 weeks. The patient had a successful delivery and preserved the uterus after surgery. Key word : Placenta acrreta spectrum, prophylatic balloon occlusion, uterine artery embolization

SUMMARY Superior vena cava syndrome often has a mediastinal malignant origin, although it is not commonly found in clinical practice. The cytology diagnosis of any mediastinal lesion is quite challenging because of the difficulty to perform any specimen collection procedure in such a location. Moreover, deep lesions that are surrounded by or have already invaded major blood vessels, make it even harder to perform a CT or Ultrasound-guided percutaneous biopsy, as well as increasing post-procedure complication risks. Therefore, mediastinoscopy is usually the first choice to collect samples whenever lesions are found in such areas, especially when surgical therapy is not recommended anymore. However, here, we performed a Forceps-supporting percutaneous endovascular biopsy on a deep mediastinal lesion, which invaded the superior vena cava-causing a superior vena cava syndrome. During the intervention, we also placed a covered stent to resolve the invasion-induced vena cava stenosis, which accomplished a diagnosis-treatment integration benefit, as the patient’s symptoms improved significantly afterward. The cytology result demonstrated a Diffuse Large B-cell Lymphoma, and our patient had his chemotherapy treatment started right away. Keywords: Endovascular biopsy, superior vena cava syndrome, covered stent

SUMMARY Background: Upper gastrointestinal bleeding from gastroesophageal varices is a frequent complication in patients with liver cirrhosis and portal hypertension. Gastric varices are difficult to control with endoscopic while endovascular intervention is an effective method. We report a case of ruptured gastric varices that was successfully treated by percutaneous transhepatic obliteration. Case presentation : A 50-year-old male patient, with a history of cirrhosis, was admitted to the hospital with a large amount of blood vomiting and black stools. Gastroscopy showed ruptured gastric varices and blood sprayed. The patient was occluded with gastric varices by percutaneous transhepatic obliteration. After 2 days, the patient's condition improved, yellow stools, and was discharged. Conclusion: Obliteration of gastric varices in patients with cirrhosis by percutaneous transhepatic obliteration (PTO) is a safe and effective technique, a good choice in the absence of gastrorenal shunt. The advantage is intervention in emergencies, no need to examine the vessels first with computed tomography. Keywords: Gstric varices, percutaneous transhepatic obliteration.

SUMMARY Objective: To investigate wherethe the perfusion parameters of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) had correlation with molecular subtypes of breast invase ductal carcinoma (IDC). Methods : Forty patients underwent 3T MRI examination following biopsied pathological immunohistochemistry at Bach Mai Hospital from March 2021 to July 2022 were retrospectively investigated. The volume transfer constant (Ktrans), the rate constant (Kep) and the plasma volume ratio (Ve) were calculated from DCE-MRI base on the extended Tofts model. The mean and standard deviation of each perfusion parameters and the pathological immunohistochemistry, subtypes correlations were assessed by Mann-Whitney U test and One-way ANOVA. Results : 40 IDC patients (mean age, 55,5 ± 11.6; range, 38 to 82 years) were investigated. The mean of Kep was higher in tumors with estrogen receptor (ER) negative (p = 0.03), progesterone receptor (PR) negative (p = 0.03), human epidermal growth factor receptor 2 (HER-2) positive (p = 0.02) than that in tumors with ER-positive, PR-positive, and HER-2-negative. Also, Kep was significantly higher in HER-2 enriched tumors than that in luminal B tumors (p = 0.01) and triple-negative tumors (p < 0.05). Conclusion: DCE-MRI may be used as the non-invase tool to assess the molecular biological expression and the molecular subtypes of invase ductal breast cancer. Keywords: Dynamic contrast enhancement, magnetic resonance imaging, subtypes breast cancer, quantitative value.
