INTRODUCTION More attention is paid recently following the increase in vascular diseases which 1MH3jnr is affecting the disability rate of the population at working age. Arteriovenous - malformation can occur at any place of human body and cause different levels of complaints and disability. OBJECTIVE Main goal was to make complete diagnosis of the AVM of lower extremity and to identify necessary coil for the treatment after to analyze the treatment result after the procedure. METHOD The treatment procedure of Lower extremity AVM was accomplished on 29 year old female at Angiography department of Shastin's Central Hospital. AVM was created by the anastomosis made between a. glutca superior, a.glutca inferior, a.obturatoria dextra and v.glutca superior, v.glutea inferior, v.obturatoria dexstra which have created pulsatile, pain at m.gluteus major et minor level. In control picture after the M.Coli embolization treatment the filling of the malformation have disappeared expressing the successful result. CONCLUSION Having previous experience of M.Coli embolization of brain vessel malformation we need to improve the skill and perform the procedure for different caliber vessels of the brain. It is preferable that we perform embolization treatment prior to surgical treatment and analyze the result.

Within the spectrum of diagnostic procedures in hepatology, the procurement of a liver specimen plays an important role. The method has been diversifi ed to encompass not only different needle types for cutting and aspiration but also different routes proceeding transvenously or transcutaneously. Over the subsequent 50 years the technique of obtaining liver biopsy samples has been modifi ed regarding the approach, the needle type, and the combination with diagnostic imaging techniques such as ultrasound, computed tomography, angiography and laparoscopy. Histological analyses are capable of establishing the etiology of a chronic or acute liver disease, are determined the inflammatory activity (Grading), degree of fi brosis/cirrhosis (Staging), are relevant for the prognosis of the patient and for indication for cost-intensive as well as potentially side are effect-prone therapies. In general, the accepted mortality rate from liver biopsy is between 0,1% and 0,01%. Among the most feared complications of liver biopsies are hemorrhage, seeding of cancer cells, infections, and injury to the viscera. The increasing number of liver transplant patients within the hepatological spectrum requires regular, safe, and high quality biopsies and their appropriate.

Introduction: A considerable proportionof adult living donor liver transplantation(LDLT) recipients experience biliarycomplication (BC), but there are few reportsregarding BC based on long-term studies ofa large LDLT population.Methods: The present study examinedBC incidence, from 16 adult and pediatricpatients (14 right liver and 2 left liver graft )between 2011 and 2016 First Central Hospitalof Mongolia.Results: The mean follow-up period was36±1 months. First Central Hospital has DDanastmosis (n=22) double DD (n=2) singlehepaticojejunostomy (n=3). There 3 caseshave biliary stricture after operation. One ofthe 3 cases has biliary laek 2 months laterafter the operation.Conclusion: Close surveillance for BCappears necessary for at least the first 3 yrafter LDLT. In terms of anastomotic stenosisrisk, HJ appears a better choice than DD forright liver grafts involving ducts less than 4mm in diameter.

Background: Spine disorder is the first cause of disability of workers below 45 years and economicalburden costs 20-50 billion us.dol, in European countries. Lumbar disc hernia estimates 40% of 30-50aged population in U.S and in Japan 26/10000. In last 5 years, spine surgeries increased in 4-5 timesdue intervertebral disc hernia, at Shastin State Third Central hospital of Mongolia.Goal: To populate new methods of surgical treatment for compressive lesions of spinal cord, spinalnerve root of cervix, thorax and lumbar spineMaterials and Methods: We did clinical research involving patients who had spine surgery at ourdepartment due “compressive lesion of spinal nerve root and spinal cord”. From, total 217 patients,excluded 9. Excluded cases are: declined from surgery 3, Arnold-Chiari malformation 5, and epiduralabscess 1. We collected data with permission of patient and did statistical analysis by IBM SPSS 17.Results: The surgery for intervertebral disc hernia takes 84.6% (176) of total surgery and 94.9% (167)of lumbar disease. Tumor of spinal cord estimates 9.1% (19) of total case, dominates in lumbar area(57.9%). We used posterior approach mostly, because it is frequently used in lumbar spine. The surgerycontinued 36-750 min (204.6, SD 128.5) ten patients (4.8%) had complications. In this project weused 5 surgical methods totally in solitary or combined. Spondilodesis is the most combined methodamong them. We used Oswestry disability index in Mongolia at first, to count treatment effect. Currentindex evaluated pre and post surgery period. Patient complaint and difficulty of daily life progressivelydecreased after surgery and almost disappeared at third month (p<0.00).Conclusion:1. It is possible to develop international standard surgical treatment of compressive lesions of spinalnerve root, spinal cord of cervix, thorax and lumbar spine in Mongolia.2. We used Oswestry disability index in Mongolia at first, so this questionnaire is simpler and accuratemethod for spine, spinal cord induced disability.3. Twenty seven point nine percent of patients who had surgical treatment has minimal to moderatedisability by Oswestry disability index, so it means we have to process standard of spine surgeryand increase non surgical treatment efficiency.4. Working ability recovers faster when spine surgery has been done.5. These new methods of spine surgery are cost effective than same surgery which will be doneabroad.
