This is a prospective study and carried out in B¹ch Mai hospital. We report our result with a group of 18 patients. All of them were undergone Doppler ultrasound and compared with contrast venography. The sensitivity and specificity of Doppler color ultrasound were determined to contrast venography (Se: 94%, Sp: 72%). Results: Doppler color has gained in precision and popularity. The technique is safer than invasive technique. It has been adapted for purpose of diagnosing deep venous thrombosis. It provides a diagnosis in a more timely and efficient manner than noninvasive technique. In equivocal cases of deep venous thrombosis, a contrast venogram should be carried out

9 patients received the angiography found 10 renal arterial stenosid or obstruction among 100 patients during 1/1995 - 3/1998. The results showed that the level of the arterial stenosid by ultrasound was quite suitable with this by the angiography. All patients received an operation for connecting the renal artery or thrombosis removal were postoperative examined by the color ultrasound Doppler and long-term monitored.

The study was conducted from January 1996 to March 1998 in B¹ch Mai Hospital. Participants were 100 hypertensive patients who have suspected renal artery stenosis after screening using clinical examination. Age of participants ranged from 9 to 50. All participants underwent colour ultrasonography and measurements are evaluated. Results showed that among 18 renal arteries of 9 patients, who received ultrasonography and angiography, 10 arteries were stenosed or occluded. 1 renal artery had suspected stenosis showed in ultrasonography, but not in angiography. So Doppler ultrasonography produced 1 false positive result, 10 true positive results, 7 true negative results and none false negative. This procedure gave high 100% of sensivity, 87.5% of speciality, positive prediction value is 90.9%, negative prediction value is 100%. Doppler ultrasonography can be used for post-operative examination and for patient following-up

A study on 16 rabbits (9 normal rabbits and 7 rabbits with the vascularization by microsurgery) aimed to evaluate the arterial fistula after experimental microsurgery has shown that although there were a little number of checked fistula (11 arteries), the blood circulation of all fistula were evaluated precisely. The study concluded that the digital angiography was considered as a good method of evaluation of the fistula in experimental rabbit.

Study on 47 rounds of chemicoembolization of hepatic artery in 24 patients with 26 hepatocellular tumors has shown that the hepatic arterial chemicocellular was interventive treatment with a very little damage for health hepatic tissues in the treatment of the primary hepatocellular cancer. The primarily results of this included embolization changed the tumor into the region without blood artery and vein, this method can be applied for the big tumor that obtained the good efficacy for local or systemic lesion.

Diagnostic peritoneal lavage (DPL) has been widely used for the evaluation of blunt abdominal trauma since its first description by Root et al in 1965. Recently, with the improvement of electronic technology, Ultrasonography (US) has been routinely used in emergency. The reliability of ultrasonographic detection (US) of hemoperitoneum in hepatic and splenic trauma was evaluated in a retrospective and prospective study of 142 patients. The sensitivity, specificity and accuracy were, respectively, 93.9%, 84.1%, and 90.8%. Laparotomy was indicated in 98 patients (69%) of US hemoperitoneum-positive cases. There were 6 false negatives and 17 false positives in this study. We believe screening method in the evaluation of blunt abdominal trauma. US might take over a great part of role of diagnostic peritoneal lavage.

The study was performed on 134 patients of primary liver cell cancer, treated through 294 episodes of chemical plug using lipiodol through the arteries, in order to evaluate the efficacy of treatment by the method of chemical plug of liver artery and to give some imaging diagnostic factors related to the effect of treatment. Results showed that all cases were intervented favorably, without death by the technique. In majority of cases, chemical improvements were notified (weight gain, pain relief in the liver...) > 6 months survival reported in 82.35%, > 12 months survival 48.24%, mean survival duration 16 months. In comparison with palliative treatment, the method of liver artery chemical plug gave higher efficacy

Apply interventional endovascular therapy in 100 patients with intracranical aneurysms between 24 and 69 years old of age from 2001 May to 2003 February. All patients underwent angiography by Seldinger's technique, then embolized by GDC coils, Cook coils or balloon. Results: success: 9 cases, fail: 1 case because of sinuous carotid arteries so that couldn't catheterization. Aneurysm embolization is efficient method. Saccular aneurysms with median size of 8-14mm are indicated embolization. Giant aneurysms are treated by embolization of carotid arteries after tested given good results

The study carries on 35 patients with intracranial arteriovenous malformation (MAV) diagnosed at faculty of neurology of Bach Mai hospital. These patients were treated by method embolization in intravascular. The injury only MVA found usually on young with 80% < 40 years old, and on man more than woman. The injury MVA of supratentorial is 91.43%, local function is 82.86%, fed by peduncle of arteria is 74.29%, reflux vein of superficial corter vein is 57.15%, return sinus vein doc tren or through vein deep purely or combined is 42.85%. The result of embolization at first step at level good is 77.4%, medial 17.14%, and dealth is 5.72%. This is independent treatment method and can also supported for surgery and surgery X ray locative

Background:Cerebral vasospasm is a proved reaction and nimodipin revolutionised the treatment of subarrachnoid hemorrhage in adult. However, the effectiveness of Nimodipin in cerebral vasospasm remained controversial in intracranial hemorrhage (lCH) in children. Objectives:This study aims to estimate the effectiveness of nimodipin in treatment of children with intracranial hemorrhage.Subjects and method:A descriptive, prospective study was conducted on all children patients diagnosed intracranial hemorrhage and treated at Neurology department of National Hospital for Pediatric, Vietnam from 2004 to June 2007. They applied the Transcranial Doppler sonography (TCD) in diagnosis of vasospasm in intracranial hemorrhage in children and follow-up the evolution after treatment with nimodipin. Results:The results showed that cerebral vasospasm with hight resistance index (RI) on TCD (RI = 0.78 \xb1 0.08) and cerebral ischemie with low systolic velocity (Vs = 68 \xb1 12.2 crn/s) and hight pulsality index (PI = 1.4 \xb1 0.13) were observed in 100% of cases after 3 days with ICH. Nimodipine improved clinical status (71.2%) and CT scan (52%), also RI, PI, Vs returned to normal when used nimodipin within 7 days of ICH. Conclusion: The treatment method for intracranial hemorrhage with nimodipin supplement had proved to have initial effecacy in comparison with traditional method.
