Anomalous Origin Of Coronary Atherosclerotic Plaques And Related Research

ObjectiveUSE the320-slice spiral CT (angiography) imaging studies of patients withanomalous origin of coronary CT imaging and imaging to explore the probabilityof occurrence of different types of anomalous origin of coronary patients withatherosclerotic plaque and provide the appropriate clinicalthe basis for thediagnosis, thus preventing clinical sudden death.Materials and methodsRetrospective analysis of CT room in the Jinan Military General Hospital inDecember2009to May2011successfully in320rows of6568cases ofcoronary angiography in patients, which detected a total of94cases of theAOCA patients and its retrospective analysis. All patients used the ToshibaAquilion one320row volumetric CT coronary angiography, the statistics of thedifferent types of coronary artery originating from the type of proportion, andanalyze the incidence of vascular atherosclerotic plaques in the larger sampleAOCA corresponding. Random sample of35normal people, as a control group,and the statistics of the incidence of the normal population each coronaryatherosclerotic plaque, followed by the application of anomalous origin of thecorresponding vascular atherosclerotic plaque incidence and normal populationcorresponds to the atherosclerosis plaque incidence χ2comparison. The control group exclusion criteria for patients with coronary anomalous origin of thepatients.Results320-slice CT can be fast volume scanning of the heart, to quickly get thevolume of data, were detected in94cases since December2009to May2011,the Jinan Military General Hospital, CT Room6568of the successful line of320-row coronary angiography patients The AOCA patients. Its occurrence rateof1.43%,95patients aged20to85years, median age of55.46years, male72cases,22cases of women, including detection of (1) RCA openings14cases ofhigh cases, the rate was14.89%.(2) RCA opening in the left sinus the numberof cases to36cases, the incidence rate of38.30%.(3) the LM opening a highnumber of cases to12cases, the incidence rate of12.77%.(4), the LAD/, LCX,the opening in the left sinus (trunk absence) the number of cases to23cases,the rate was24.47%.(5), LCX, the origin of the number of cases in the rightcoronary artery of nine cases, the rate was9.57%. Normal population (1)corresponding to the LAD35and14cases of plaque was40%.(2) LCX,35cases of six cases, the rate was17.14%.(3) RAC35cases there are five caseswith plaque, the rate was14.29%. After the application of abnormal origin ofpatients with vascular corresponding normal population of blood vessels χ2comparison. Come to the origin of right coronary sinus, left, right coronary arteryatherosclerotic plaque was41.47%incidence of14.29%compared with thenormal population the right coronary artery atherosclerotic plaque, thedifference was significance (P <0.05), the rest were not statistically significant(P>0.05).Conlusion320-slice CT can be successful volume scan of the heart, it can clearly show the blood vessel and its Traveling from the above data to come to the leftof most of the anomalous origin of coronary atherosclerotic plaque was notstatistically significant, only the origin of the right coronarysinus (P <0.05) werestatistically significant, this proposal should be the same with diabetes, highblood pressure classified as atherosclerotic plaque to one of the predisposingfactors, check out AOCA especially the origin of the right coronary leftsinusshould pay particular attention to guide clinical treatment and prevention ofthe occurrence of acute coronary syndrome.
