【摘要】：目的： 通過多排CTA研究腎動脈及其血管變異相關(guān)解剖學(xué)數(shù)據(jù)，目的是為更好的清晰腎動脈的解剖結(jié)構(gòu)，和復(fù)雜的腎動脈解剖變異分類、分型。為臨床上相關(guān)的腹腔鏡手術(shù)，介入治療，腎臟移植提供所需的解剖學(xué)資料。 材料與方法： 選擇2008年11月~2010年01月疑有腎臟病變而行64層螺旋CT增強檢查的512例患者影像資料,其中男356例,女156例,年齡18~82歲,平均52.5歲,使用東芝Aquilion64層螺旋CT機,掃描范圍為膈肌至髂嵴。觀察雙側(cè)腎動脈內(nèi)徑、長度、腎門處動脈上緣距腎上極的距離并定位開口位置。觀察雙側(cè)副腎動脈內(nèi)徑，長度，并計算出現(xiàn)率。觀察變異腎動脈類型并統(tǒng)計各類型出現(xiàn)次數(shù)。 結(jié)果： 1.左腎的長徑、寬徑、及厚度均大于右側(cè)。左側(cè)腎臟長徑103.2±5.0mm，寬徑51.2±5.0mm，厚度49.1±6.2mm；右側(cè)腎臟長徑99.9±4.0mm，寬徑50.4±5.4mm，厚度46.5±4.0mm。 2.左側(cè)腎動脈內(nèi)徑大于右側(cè)，長度小于右側(cè)。80.4%右側(cè)腎動脈開口位置高于左側(cè)，，平均高出5.07±7.43mm。 左側(cè)腎動脈內(nèi)徑5.0±0.7mm，長度44.4±4.7mm，腎門處動脈上緣距腎上極的距離43.6±8.9mm。右側(cè)腎動脈內(nèi)徑5.4±0.7mm，長度53.4±6.0mm，腎門處動脈上緣距腎上極的距離40.6±6.5mm。 3.副腎動脈開口：由腎上端入腎者32支,占45.7%;由腎下端入腎者25支,占35.7%;由腎門周圍入腎者13例,占18.6%。左側(cè)副腎動脈內(nèi)徑2.64±0.6mm，長度44.78±3.6mm，出現(xiàn)率42.40%。右側(cè)副腎動脈內(nèi)徑2.58±0.4mm，長度46.76±4.2mm，出現(xiàn)率41.15%。 腎動脈變異類型統(tǒng)計結(jié)果Ⅰ類變異A:21，B:10，C:14，D:1，E:2。Ⅱ類變異A:3，B:1,C:0，D:0，E:4。 結(jié)論 1.多排螺旋CTA可直觀地、準確地顯示腎動脈及其變異的數(shù)目。 2.腎臟動脈的變異水平較大，在術(shù)前行腎臟CTA檢查可明確腎臟動脈的變異情況，從而避免術(shù)中損傷。
[Abstract]:Objective: The anatomical data related to the variation of renal artery and its vessels were studied by multi-row CTA in order to better understand the anatomical structure of renal artery and to classify the complex anatomic variation of renal artery. Type. Provide anatomical data for clinical related laparoscopic surgery, interventional therapy and kidney transplantation. Materials and methods: From November 2008 to January 2010, a total of 512 patients with suspected renal lesions were examined by 64-slice spiral CT, including 356 males and 156 females. The mean age was 52. 5 years old. Toshiba Aquilion64 slice spiral CT was used. The scanning range was from diaphragm to iliac crest. The diameter and length of bilateral renal arteries were observed. The distance from the superior edge of the renal artery to the upper pole of the renal artery and the location of the opening were observed and the internal diameter and length of the bilateral accessory renal artery were observed and the occurrence rate was calculated. The type of the variant renal artery was observed and the occurrence times of each type were counted. Results: 1. The length, width and thickness of the left kidney were larger than those of the right. The left kidney was 103.2 鹵5.0mm in length, 51.2 鹵5.0mm in width and 49.1 鹵6.2mm in thickness. The right kidney was 99.9 鹵4.0 mm in length, 50.4 鹵5.4 mm in width and 46.5 鹵4.0 mm in thickness. 2. The diameter of left renal artery was larger than that of right, and the length of right renal artery was smaller than that of right. 80.4% the position of right renal artery opening was higher than that of left side, which was 5.07 鹵7.43 mm higher than that of left side. The left renal artery was 5.0 鹵0.7 mm in diameter and 44.4 鹵4.7 mm in length. The distance from the superior edge of the renal artery to the upper pole of the renal artery was 43.6 鹵8.9 mm, the diameter of the right renal artery was 5.4 鹵0.7 mm and the length of the right renal artery was 53.4 鹵6.0 mm. The distance from the superior edge of the renal artery to the upper pole of the kidney was 40.6 鹵6.5 mm. 3. Accessory renal artery orifice: 32 of them entered the kidney from the upper end of the kidney, accounting for 45.7%; 25 of them entered the kidney from the lower end of the kidney, accounting for 35.7; The left accessory renal artery was 2.64 鹵0.6mm in diameter and 44.78 鹵3.6mm in length. The diameter and length of the right accessory renal artery were 2.58 鹵0.4mm and 46.76 鹵4.2mm, respectively. Statistical results of variant types of Renal Arterias: class I variant A: 21B: 10C: 14D: 1. Class 鈪
