The authors make imaging criteria of intracranial aneurysm. Roles of MRI with high resolution, multiplan, signal of follow voix by TOF, PC... was confirmed in the evaluation of aneurysm. An analysis on the results of 23 patients was admitted into hospital in emergency. Subarachnoid hemorrhage due to rupture of an aneurysm: sacciforme: 100%, <10mm (5 patients): 21.7%; 10-25mm (16 patients): 69.6%; > 25mm (2 patients): 8.7% (giant cerebral aneurysm. Some different signs between small and giant aneurysm were detected in T1W, T2W.

Lung paragonimiasis is a disease caused by lung flukes characterized by the migration of a juvenile worm in early stage and the formation of cysts around the worm later on. We report a case of pulmonary paragonimiasis in the childhood causing recurrent haemoptysis and pneumonia. The purpose of this study was to describe the radiological manifestations of pulmonary paragonimiasis on chest X-rays and CT-Scans-Peripheral localized, multisegmental infiltration with pleural thickening of lesion, Focal and infiltrative shadows (10-15mm nodules + masslike consolidation). Bollous inflation (excentric thickening of Cyst wall). CT-scans provide more specific information

The contrast substances have been used in the magnetic resonance imaging (MRI) to increase the sensitivity and specificity of diagnosis. It impacts on the density of proton and spin-spin time (T1 and T2). There were many different substances studied to increase the density of proton such as water, alcohol, hydrocarbon, and sugar or perfluoroctyl bromide. However, only paramagnetic compounds impacts on the spin-spin time were studied much and are being used.

A retrospective and cross sectional survey was carried out in 52 patients with cervical disc displacement who were screened by magnetic resonance at Viet Duc Hospital and Military Hospital 103 from Jan 2003 to Oct 2004. Sites of common displacement: C5-C6 (36.61%); C4-C5 (26.79%); C3-C4 (23.21%); C6-C7 (11.61%); C7-D1 (1.79%). Disc displacement in one layer was 42.31%, in two 11.54%, in three layers 34.61%, in four 11.54%, in centre 71.43%, beside centre 25%, in foramen 3.57%. Displacement image was looked clearly in T1W and T2W image. 100 displaced discs reduced signal in T2W image, 63.46% reduced disc height, 42.31% increased medulla signal equal with site of displacemen in T2W image

Background: The effective dose of Tranexamic Acid (TA) is unclear in reducing blood loss after cardiac surgery. In Vietnam, the doses of TA 10mg/kg for starting anaesthesia, 5mg/kg for transfusion into extracorporeal circulation solution, then using a maintained dose of 1mg/kg/gi\u1edd reduces blood loss and transfusion, but there is no statistical significant. Objectives: To evaluate blood loss and need for transfusion after cardiac surgery in patients receiving TA 20 mg/kg at induction + 10 mg/kg in extracorporeal circulation solution and 2 mg/kg/1h for maintenance; To evaluate coagulation profile after TA. Subject and methods: A double blind randomly controlled trial is conducted in 80 surgical cardiac patients equally divided into TA and control groups: Results: In the TA group, the post - operative blood loss is 393.50 \xb1 136.64 ml, Hematocrit (Hct) 35.31 \xb1 3.38 % with less individuals and smaller amount of blood and/or frozen fresh platelets needed than in control (p<0.001). Conclusions: An above dose of TA reduces approximately a half of blood loss and elevates Hct postoperatively, with significant lower requirements of transfusion than the control and higher amount of platelets, reduced D-dimers (p<0.05) and unchanged Fibrinogen, PT, INR and aPTT (p >0.05).

Background: Patients who received multiple transfusions of blood and blood products may produce antibodies against antigens of erythrocytes, leukocytes, platelets etc, resulting in many clinical implications. Objectives: To detect frequencies of antineutrophil antibodies in multitransfused patients at National Institute of Hematology and Blood Transfusion (NIHBT). Subjects and methods: The study was conducted on 30 multitransfused patients. Among them there were 12 with thrombocytopenia and 18 with aplastic anemia. Results: 6 cases had anti - neutrophil antibodies, of which 5 had more than 5 times of transfusion, 4 with aplastic anemia and 2 with thrombocytopenia. The sera were further tested with neutrophil panel, revealing 4 samples with anti - NA 1 (13.3%) and 1 sample with anti - NA2 (3.3%). The frequency of anti - neutrophil antibodies in multitransfused patients at IHBT in the study is 20%. Conclusion: Frequency of anti-NA1 was higher than anti-NA2 in multitransfused patients at NIHBT and directly proportional by frequency of NA1 and NA2 antigens in this group. The technical process to identify and classify antineutrophil antibodies in this study can be applied for patients who received multiple transfusions of blood and blood products in Viet Nam

Objective: To evaluate the effectiveness and safety of electroacupuncture in conjunction with additional medications in providing analgesia and stabilizing hemodynamic parameters during total thyroidectomy. Methods: This randomized controlled trial included 100 patients who underwent a total thyroidectomy between October 2022 and October 2023 at the Vietnam National Hospital of Acupuncture. The patients were randomized into two groups. The electroacupuncture analgesia (EA) group received EA stimulation at five acupuncture points: Hegu (LI 4), Neiguan (PC 6), Shuitu (ST 10), Quepen (ST 12), and Yifeng (SJ 17), while the control group received a bilateral superficial cervical plexus block. Primary outcomes included the level of analgesia and perioperative vital signs in both groups. Additionally, pain thresholds and serum β-endorphin levels were measured before and after electroacupuncture in the EA group. Results: Complete analgesia (Level A) was attained in 86% and 76% of the patients in the EA and control groups, respectively, with no significant difference between the two groups (P = 1.00). In the EA group, the mean pain threshold after receiving EA doubled (648.7 (77.4) g/s vs. 305.3 (45.3) g/s, P < .001), and the mean serum β-endorphin level increased by approximately 13.5 pg/mL (P < .001). All patients remained hemodynamically stable throughout the surgery. Conclusion EA, in conjunction with additional medications that stimulate five acupuncture points, LI 4, PC 6, ST 10, ST 12, and SJ 17, was well tolerated and effectively maintained a suitable level of analgesia and hemodynamic stability during total thyroidectomy.
