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.

Transarterial embolization in management of congenital renal arteriovenous malformation SUMMARY Objective: To evaluate the safety and efficacy of transarterial embolization (TAE) in management of congential renal arteriovenous malformation (AVM). Patients and Methods: Between December 2007 and June 2015, 11 patients with congential renal AVM treated with TAE was investigated for clinical presentation, imagine features, treatment methods and complications in Viet Duc hospital. Results: 11 patients (9 women/2 men) with 10/11 gross hematuria, 5/11 flank pain and 1/11 hypertension underwent 11 sessions of treatment, TAE was performed with histoacryl + lipiodol in 7 patients, micro-coils in 3 patients, absolute alcohol and histoacryl in 1 patient. Technical and clinical success were obtained in all patients. There was only 1 patient with fever, renal function was normal in all patient pre - embolization and post - embolization. Conclusion: TAE treatment was safe and effective, it should be recommended as the first choice to treat congential renal AVM. Key word : renal arteriovenous malformation, embolization.

Cardiac Magnetic Resonance Imaging in diagnose Ischemia Heart Disease SUMMARY Objective : Accuracy of Cardiac Magnetic Resonance in diagnose ischemia heart disease with patients suspected coronary artery disease (CAD) in comparison to invasive angiography. Material and Methods: Thirty-five patients (61.54±11.23 years, 27 men, 71.4% CAD) underwent CMR including cine, short axis to evaluate EF, EDV, ESV, stress PERF (adenosine 140 μg/ min/kg), rest PERF (SSFP, 3 short axis, 1 saturation prepulse per slice) and LGE (3D inversion recovery technique) using Gd- BOPTA. Images were analyzed visually. Stenosis >50% in invasive angiography was considered significant. Results : Mean study time was: 41.37±11.04 minutes, EF: 48.95±18.55%, Hypokinesia: 57.1%, Akinesia: 17.1%. Sensitivity for PERF, LGE and the combination of PERF/LGE was 100%, 82.4%, 100%, respectively and specificity 80%, 80%, 80%, respectively. PPV: 94.4%, 93.3%, 94.4%, NPV: 100%, 57.1%, 100%. A good relation (p<0.01) between deficit perfusion state, the levels of myocardial delayed enhancement correlation with coronary stenosis of LAD, RCA, LCx. Conclusion: In patients with CAD, the combination of stress PERF, LGE is feasible. A combined perfusion and infarction CMR examination with can diagnose CAD in the clinical setting. The combination is superior to perfusion-CMR alone. Key words : Cardiac Magnetic Resonance(CMR), diagnose, ischemia heart disease (IHD), coronary artery, late gadolinium, perfusion.

The efficacy embolization in treatment of renal arterial trauma SUMMARY Pupose: to apply and estimate the efficacy of embolization in renal injury. Material and method: 26 patients were undergone renal angiography and embolization at Viet Duc hospital from 1/2010 to 8/2013. Among those patients, 23 cases showed pseudoaneurysm, 2 cases showed extravasation and 1 case showed AVM on CT scan. Result: All patients who underwent embolization did not show extravasation (100%) and ongoing hemorrhage required laparotomy on angiography postoperative. Conclusion : In hemodynamically stable and controlled patients, selective and superselective embolization is a safe and effective method for the management of renal vascular injury.

An initial study on the role of 320 detector row CT in Myocardial Perfusion evaluation SUMMARY Objective: To study the role of 320 detector row CT in myocardial perfusion evaluation . Material and Methods: A prospective and descriptive study was carried out on 12 patient with moderate or highly moderate risk of coronary artery diseases from December 2018 to May 2019 at Central Military Hospital 108. Results: 10 male and 2 female, the average age was 63,2. 91.7% of the patients had myocardial ischemia with tranmural perfusion ratio (TPR) ≤ 0,99. The number of coronary arteries had perfusion abnormalities accounted for 38.9%. The diagnostic accuracy increased after perfusion analysis with sensitivity from 83.3% to 91.7% and specificity from 75.0% to 91.7%.\ Conclusion: 320 detector row CT is an effective method to perform both coronary CT angiography and CT perfusion imaging in the same examination . Now we are continuing to collect and study on more patients. Keywords: Myocardial perfusion, tranmural perfusion ratio, computed tomography.

Assessment of left ventricular dyssynchrony by SPECT myocardial perfusion imaging in post myocardial infartion patients SUMMARY Objective: to evaluate left ventricular synchrony parameters using gated myocardial perfusion single photon emission computed tomography (GSPECT) in post myocardial infarction (MI) patients. Subject and methods: a cross - sectional study was conducted on 34 subjects without cardiovascular disease and 104 post-MI patients. Results : left ventricular dyssynchrony parameters including PSD and HBW were 48.7 ± 19.49 and 154.95 ± 71.97 in post-MI group compared to 17.5 ± 7.24 and 53.9 ± 15.14 respectively in control group (p<0.01). 77% and 81% of post-MI patients had increased PSD and HBW with left ventricular dyssynchrony. PSD and HBW has increased significantly in post-MI patients with NYHA III-V, low EF compared to NYHA I-II patient group without left ventricular dysfunction. Conclusion : left ventricular dyssynchrony parameters were commonly detected by gated SPECT in post-MI patients. PSD and HBW increased significantly in post-MI patients and had relationships to NYHA and left ventricular dysfunction. Keyword: myocardial perfusion imaging, left ventricular dyssynchrony, myocardial infarction.

Single coronary artery: classification and clinical significance SUMMARY Objectives: To evaluate ratio and classification single coronary artery in the MSCT cardiac. Material and Methods: Prospective study of 9,868 patients who had scanner MSCT cardiac in Ha Noi Heart Hospital from February, 2015 to September, 2017. Results: The study included 9,868 patients, 43 patients (0,44%) had single coronary artery. 11/43 patients (25,6%) had single coronary artery were isolated. 32/43 patients (74,4%) associated had congenital heart diseases other: 7 patients had Fallot 4, 3 patients had truncus arteriosus, 2 patients had pulmonary atresia, 1 patient had double outlet right ventricle, 1 patient had double discordance and 18 patients had complex congenital heart diseases. Included 43 patients had single coronary artery: 16/43 patients ( 37%) in the type R, 25/43 patients (58%) in the type L and 2/43 patients (5%) not in the current classification who had singler coronary artery high takeoff from truncus brachiocephalic artery. Type L I was 5%, type L II – A: 21%, type L II – B: 18%, type L II – P: 14%, type R II – A: 18%, type R II – B: 12%, type R II – P: 5% and type R III: 2%. Conclusions: Singler coronary artery is a rare congenital anomaly. MDCT cardiac is a non-invasive technique, reliable, that provides accurate information about coronary artery anatomy well as other complex congenital heart diseases. Single coronary artery is a great challenge for surgery to repair the entire congenital heart disease that accompanies it.
