摘要
目的研究64层螺旋CT三维重组对气管支架置入术后的评价及其在随访中的应用价值。资料与方法气管狭窄患者35例,男18例,女17例,年龄29～91岁,平均62.5岁。恶性气管狭窄30例,良性器质性气管狭窄5例,共置入支架40枚。支架置入术后3～7天及3～12个月内分别两次行64排多层螺旋CT检查,以容积再现(VR)、多平面重组(MPR)及CT仿真内镜成像(CTVE)多种方式重组。对支架置入术后的通畅、位置、形态、邻近气道、术后合并症等情况进行观察、评估。结果CT图像中均观察到由金属支架引起的较小伪影,但并不妨碍判读图像。支架的形态、位置、范围、通畅程度,邻近气道的状况以及各种支架特有的并发症均清晰可见。结论64层螺旋CT三维成像作为一种方便、快捷、无创的检查方法能够较客观地评价气管支架置入术后情况,对于气管支架置入术后的随访有很好的应用价值。
Objective To evaluate the value of 64-slices spiral CT three-dimensional reconstruction to analyze the complications of tracheobronehial stent implantation on follow-up. Materials and Methods Thirty-five patients with 40 endobronchial metallic stents inserted for local advanced malignancy （ n = 30 ） or benign diseases （ n = 5 ） performed follow-up （M-slices spiral CT scan 3 to 7 days after operation and 3 - 12 months after operation. All the data were reconstructed using VR, MPR and CTVE. The location, shape, patency, complication of stents and adjacent airway were assessed. Results Fifteen stents （32.5%） remained patent without deformation in their original position. Twenty-five stents （67.5%） were associated with local complications included migration （ n = 1 ）, external compression with persistent stenosis （ n = 7） , excessive granulation tissue （n = 10） , noncongruence between the airway and the stent （n = 1 ） , and mucus blockage（ n = 6）. Conclusion （M-slices spiral CT three-dimensional reconstruction imagings can assess the stents situation after implantion,as a convenient, fast, non-invasive screening method, which have a good value in tracheobronchial stent follow-up.
