 Hello all, I am Dr. Krishnameni, final year radiology PG from Arbadae Vedu Medical College and Hospital. Title for my paper presentation is Celiac artery trunk, permanent hepatic artery and renal artery anatomical variance detection, prevalence in association, analysis with multi-detector CT. Introduction, anatomical variance of the hepatic artery and Celiac trunk are of time importance in liver transplantation, laparoscopic surgery, radiological intervention and penetric injuries to the abdomen. The chance of inadvertent or iotrogenic vascular injury rises in the event of aberrant anatomy. The presence of renal artery variation is significant in surgical management of renal vascular hypertension, renal transplantation and interventional radiological procedures, where it is important to know the origin and course of these arteries. The aim of the study is to determine the anatomical variant of Celiac axis, hepatic artery, renal arteries and the perversiveness with use of contrast enhanced MDTCP. Each arterial system was an individually defined and recorded using Fluckers classification system for Celiac artery and Michael's classification for hepatic arteries. The renal arteries were assessed with respect to their origin, number of arteries and laterality. The association of renal and Celiac hepatic artery variation is statistically evaluated. Now, retrospective observation study has been conducted with 500 constitutive cases from May to September 2021 and the sample size is 500 with the gradient echo, bright speed, light, 16 slides, 16 scanner. The inclusion criteria includes all age groups with both sexes who are referred for the contrast enhanced MDCT abdomen. Exclusion criteria with the patient of having history of major upper abdominal surgery, patients with occlusion of Celiac hepatic and renal arteries. Scans were performed in the axial scans, axes starting from the domes of diaphragm up to the pubic symphysis, first in plane followed by contrast multi-physics scans and the slide thickness is 5 mm, rotation time is 0.8 second, retrospective reconstruction parameters were also taken. So the results and observation, it is most commonly seen in males with 57% and variants of Celiac trunk is seen predominantly in males, hepatic artery showed a predominance of males and renal artery variants are seen most commonly in females. Celiac trunk variants, Celiac bifurcation was considered more unseen more compared to Celiomyscentric trunk, Celiac counterification and others. So Celiac trunk variation was classified according to Flakar's classification where in 465 number of cases had classical Celiac trunk trifurcation followed by Hepatose cleaning trunk, Hepatogastric trunk, etc. So renal artery variation, left accessory renal artery was seen most commonly that is 80 and renal artery variation in 334th case of patient had normal anatomy followed by two renal arteries on the right and on the left. Hepatic artery variants, 39 was seen in replaced left hepatic artery originating from the left gastric artery followed by accessory left hepatic artery originating off the left gastric artery replaced right hepatic artery originating from the SMA. So hepatic artery variation were classified using mycels where 381 cases had normal anatomy followed by replaced left hepatic artery originating from the left gastric artery. Celiac or hepatic artery variation without renal artery variation was seen in 89 cases, 89 positive cases and Celiac or hepatic artery variation with renal artery variation is seen in 65. So in our retrospective study in 500 patients there was normal triification of Celiac trunk in 465 patients that is 93 percentage, hepatitis cleaning trunk and gastro cleaning trunk in 15 patients, quadrification in 5 patients, celium eccentric trunk in 1 patient and other variants seen in 14 patients. Hepatic artery variations were present in 119 patients and renal artery variation in 166 patients. Results Celiac trunk or hepatic artery variation was present in 89 of 334 patients with no renal artery variation and in 65 of 166 patients with renal artery variation. There is an increased prevalence of Celiac hepatic artery variation in individuals with accessory renal arteries. Now we will see the cases. Case 1 and case 2 shows the quadrification of the Celiac trunk. Case 3, case 4 and case 5 and case 6 shows the splenic artery and hepatic artery separates origin from the iota. Post-contest MIPCT image in transaxial section shows the separate origin of common hepatic artery and directly from the iota at the same level, allergenetic Celiac axis with congenital narrowing and elephant trunk is seen in case 6. Its cause of common hepatic and splenic artery was made. Case 7, we are seeing a common hepatic artery originating from the iota. It is also demonstrated in the volume rendering CT. And case 8, we can see the common hepatic artery arising from the SMA. It is also demonstrated in the case 9. Case 10 and 11 shows the right hepatic artery originating from the Celiac trunk and case 11 shows the right hepatic artery originating from the iota. So case 12, two accessory right renal arteries and one accessory left renal arteries are noted. Case 13 shows the accessory right renal artery and case 14 shows the accessory left renal artery. So in our study, Celiac trunk and hepatic artery variants had showed a higher incidence in males whereas renal artery variants showed a peak incidence in females. Celiac trunk trifacation was seen in 93% and 7% showed variation comparable with 4.5% according to the cornoffel et al. Celiac trunk bifurcation was seen in 3% qualification in one person, Celiac was centric trunk in 0.2% and others in 2.8%. Renal arteries were common on the left than on the right. Celiac trunk or hepatic artery variations were present in 3-34 patients with no renal artery variations and in 65 of 166 patients with renal artery variation. This denotes a statistically significant correlation between hepatic Celiac and renal artery variation. Such similar associations has been reported previously in the study done by Norel et al. Thus our study indicates that there may be some common factor associated in causing variation in two unrelated arterial system during embryogenesis. So coming to the conclusion, the anatomy and variation of the Celiac trunk, hepatic artery and renal artery need to be established at preoperative imaging to minimize the iotrogenic arterial injury that could occur during organ transplantation, laparoscopic surgery, radiological abdominal intervention, endovascular procedures, surgical treatment of penetrating injuries to the abdomen and surgical treatment of renovascular hypertension.
