The Anatomy Study Of The Middle Colic Artery

Objective:In the study of the middle colic artery relevant anatomy data, as well asits deep face adjacent to the anatomical location of the structure. Ourpurpose is to better ensure the smooth implementation of abdominalsurgery, surgery cut skin area, and its security area, for upper abdomentransverse mesocolon related clinical surgical anatomy data as needed.Materials and methods:60with30cases (30cases of male, female) through teaching in formalinfixed adult specimen, specimen is complete, the structure of abdominaldeformity without pathological changes, unknown age. Structure andobservation records middle colon arteries branch pipe diameter, long dryand left and right, the Angle between the measurement and the location ofthe positioning on the operation of abdominal surgery, measuring andpositioning the location of the middle colic artery. Measurement ofmiddle colic artery with the surrounding adjacent to the relationship.The results:1.Alone middle colon artery origin of average diameter is1.8mm,total dry an average of3.4mm; Alone pair of colonic artery origin inaverage diameter of0.36mm, do an average of0.87mm. 2.Work alone middle colon artery origin place of long with anaverage of3.15mm, total dry an average of3.76mm; Work alone vicecolon artery origin in long with an average of1.89mm, do an average of2.21mm.3.Middle colon artery in the left and right sides of the Anglebetween the assumes the acute Angle of a total of38cases (63.34%) andthe rest of the results of obtuse Angle respectively (34.47%) and right(2.19%).4.Middle colon artery of28cases from the superior mesentericartery, from the initial point of the average distance of the superiormesenteric artery;10cases up from superior mesenteric artery withright colic artery, from the initial point of the average distance of thesuperior mesenteric artery; Three left over from the superior mesentericartery with back to colon arteries, is apart from the initial point of theaverage distance of the superior mesenteric artery; There are2casesfrom the celiac artery; There are lack of1case.5.Middle colon artery to go it alone from the superior mesentericartery, a total of34cases with is apart from the edge of the pancreaticbody on the average, there are33cases of origin status of24.68mm, andin the rear of the pancreas in1case from the superior mesenteric artery.Colic artery and right colon in total bottom from the superior mesenteric artery in26cases, including the average distance between the edge of the25cases of pancreatic body is29.54mm, and1case of origin at the edgeof the pancreatic body origin.Conclusion:1.In abdominal surgery, down through the edge of the pancreas2cmfind the starting point of the superior mesenteric artery, and down3.75cm will find middle colic artery in a point.2.Middle colic artery in surgery after start from the superiormesenteric artery,there is a contorts upwards, with the left go to thetransverse mesocolon middle1/3and the right go to the transversemesocolon right1/3, before the operation doctors can find the middlecolic artery first, and effectively protect it.3.The distribution of the colic artery in a regular, its common branchhas three, often left half colon nutrition and transverse left, left rightbranch often right-side colon nutrition and right colon, deputy in colonartery throughout the left, in the colon cancer radical, should chooseaccording to tumor location corresponding artery ligation, avoidexcessive ligation cause of postoperative bowel necrosis.
