腹股沟疝和股疝的多层螺旋CT表现

屠的研究腹股沟疝和股疝的多层螺旋CT（mLilti—Slice spiralcT，MSCT）表现，探讨如何通过MsCT对腹股沟疝和股疝做出诊断与鉴别诊断。方法回顾性分析30例经手术证实的腹股沟疝和股疝MscT包括多平面重组（multi planar reformation。MPR）表现，重点观察疝的位置、形态、走行、内容物及与周围结构间的关系以及继发征象。结朵MSCT诊断腹股沟斜疝16例，腹股沟直疝11例，股疝3例。16斜疝中l2例有腹股沟深环的扩大，16例显示腹股沟管的扩大。以耻骨结节为参考点，10例斜疝和4例直疝跨越中线位于外上象限和内上象限，3例股疝则位于外下象限。3例股疝中2例显示股静脉受压变形。结论MSCT能够显示腹股沟疝和股疝的位置、形态、走行、内容物、与周围结构之间的关系及并发症，能够为腹股沟疝和股疝的诊断与鉴别诊断提供有价值的信息。对于腹股沟疝和股疝的诊断与鉴别诊断，应综合观察腹股沟管、腹股沟管深环的改变以及疝与腹壁下血管、股血管、腹股沟韧带的关系，并重视多平面重组在诊断中的应用价值。

The Findings of Inguinal Hernia and Femoral Hernia on Multi-slice Spiral CT

Objective To study the multi-slice spiral CT （MSCT） features of hernia of inguinal hernia and femoral hernia, and to explore the diagnosis and differential diagnosis of inguinal hernia and femoral hernia with MSCT. Methods 30 cases with inguinal hernia and femoral hernia confirmed by operation were retrospectively analyzed. All cases were un- dergone the MSCT examination. The key point of observation was the position, course, herniated contents, adjacent structures as well as complications. Result A total of 30 subjects were enrolled in this study, 16 were indirect inguinal hernia, I l were direct hernia, 3 were femoral hernia. 12 indirect hernia displayed enlargment of the groin deep ring, and 16 indirect hernia showed enlargment of the inguinal canal. When took the pubic tubercle as the point of reference, 10 indirect hernia and 4 direct hernia located in upper outer quadrant and upper medial quadrant, yet 3 femoral hernia located in lower outer quadrant. 2 femoral hernia showed venous compression. Conclusion To make right diagnosis of inguinal hernia and femoral hernia, a comprehensive observation of the changes of internal inguinal ring. inguinal canal and the relationship between the hernia and the adjacent structure such as the inguinal ligament, the inferior epigastric vessels, femoral vessels should he made. Meanwhile. importance should be attached to MPR＇ role in the diagnosis of inguinal hernia and femoral hernia.
