螺旋CT对肠扭转的诊断价值

Value of Spiral CT in the Diagnosis of Intestine Volvulus

目的:探讨螺旋CT对肠扭转的诊断价值。方法:回顾性分析11例术前CT明确诊断并经手术证实为肠扭转的临床及影像资料。结果:11例肠扭转CT均正确诊断,其中6例为360°肠扭转,4例为270°肠扭转,1例为180°肠扭转。除全部11例都有通常的肠梗阻征象外,主要征象还有"漩涡征"(9/11)、"靶环征"(4/11)及"鸟喙征"(10/11),肠系膜血管也可以形成"漩涡征"(11/11)。结论:螺旋CT对肠扭转具有重要的临床价值,尤其是肠系膜血管的"漩涡征"。

Objective：To study the value of spiral CT in the diagnosis of intestine volvulus. Methods：The clinical and CT materials of 11 cases with intestinal volvulus which were diagnosed by CT before surgery and proved by operation were retrospectively analyzed. Results： All of the 11 cases were accurately diagnosed by CT before operation, including torsion with 360° （6 cases） ,270° （4 cases） and 180° （1 case）. The main features were signs of intestinal obstruction （11/11 cases）, ＂whirlpool＂ sign （9/11 cases）, ＂target sign＂ （4/11 cases）and ＂beak＂ sign （10/11 cases） ,and ＂whirlpool＂ sign of mesentery vessels were showed in all 11 cases. Conclusion： Spiral CT especially the ＂whirlpool＂ sign of mesentery blood vessels, provides important clinical value in the diagnosis of intestine volvulus.
