Using volume rendering and 3D reconstruction to analyze the anatomical variation of the left renal arteries with type IIC: a case report
-
摘要: 本文报告1例左肾动脉IIC类变异。患者术前行腹部增强CT扫描,发现其左肾动脉走行存在变异。肾动脉变异在临床上较为少见,然而在肾脏疾病的外科治疗中,解剖变异的发生却易引起较为严重的影响。因此,在术前对肾动脉走形及变异进行充分的了解,能减少泌尿外科手术的术中损伤、并能提高手术成功率、加快患者术后恢复。Abstract: We report a case of the anatomical variation of the left renal arterial vasculature with type IIC in gastric cancer patient. The patient was performed with a preoperative CT enhanced scan.It was found that his left renal arterial anatomical variation. Variations of the renal arteries is rare anatomy variation, but while healing renal and urinary system disease, anatomy variation can cause misdiagnosis and increase the complexity of healing diseases. Adequate understanding of renal arteries normal anatomy and its variations before the surgery is meaningful in urological laparoscopic nephrectomy, urological laparoscopic partial nephrectomy, reduce the injury in urological surgery, increase the successful surgery rate and accelerate the recovery of the patient after the surgery.

图 2 三维重建
A: 患者三维重建后正视图, 重建结构有第十二胸椎(灰白色)、第一腰椎(灰白色)、第二腰椎(灰白色)、第一和第二腰椎间盘(白色)、腹主动脉(红色)、主肾动脉(蓝紫色)、副肾动脉主干(绿色)及其分支(进入肾上极为土黄色,进入肾门为亮黄色)、左肾(棕色透明处理); B: 侧视图, 显示左主肾动脉发出自腹主动脉侧壁第一腰椎中间偏上水平, 左副肾动脉发出自腹主动脉侧壁第一腰椎、第二腰椎间椎间盘水平; C, D: 血管走形示意图1、血管走形示意图2;主肾动脉、副肾动脉入肾门处血管走形情况,可见主肾动脉进入肾门后供应肾的上段、上前段、下前段、下段。副肾动脉入肾门支供应肾的上段、后段、下段; E:局部放大示意图,可见主肾动脉、副肾动脉、分支1:入肾上极、分支2:入肾门.
