摘　　要：目的分析并总结SVCS中体-肺静脉瘘的CT征像及出现规律。方法将上腔静脉综合征按照阻塞部位分为3组:奇静脉弓上阻塞、奇静脉弓下阻塞、奇静脉弓上下均受累。再分为胸膜肥厚组与非胸膜肥厚组。结果奇静脉弓上阻塞9例、奇静脉弓下阻塞7例、奇静脉弓上下均受累17例,均为重度阻塞或完全闭塞。胸膜肥厚组10例,非胸膜肥厚组23例。结论SVCS中体-肺静脉瘘有2种表现形式,一种为头臂静脉通纵隔内迂曲的引流静脉与上肺静脉形成体-肺静脉瘘。另一种为通过增厚的胸膜形成体-肺静脉瘘。体-肺静脉瘘的出现与阻塞部位或胸膜肥厚与否关系密切,容易出现在弓上下阻塞组或胸膜肥厚组中。Objective To observe enhancement of CT imagining of systemic-to-pulmonary venous shunts in patients with superior vena cava syndromes （SVCS）. Also to analyze the notable and reoccurring characteristics of systemic-to-pulmonary venous shunts, neth- otis Divide 33 SVCS patients into three groups according to the position of blocking： position of blocking above the azygos vein, position of blocking below the azygos vein, position of blocking above and below the azygos vein. Also divide 33 SVCS patients into two groups ac- cording to pleural thickening or not. Results There are 7 patients in the group of blocking above the arch of azygos vein, 9 patients in the group of blocking below the arch of azygos vein, and 17 patients in the group of blocking above and below the arch of azygos vein. There are 10 patients in the group of pleural thickening and 23 patients in the group of pleural not thickening. Conclusion Systemic-to-pulmo- nary venous shunts in superior vena eava obstruction eommonly shows in two forms of on eomputer tomography. Shunts occurrence are closely related to position of blocking in superior vena cave and pleural thickening or not, it frequently occurs in the group of blocking a- bove and below the arch of azygos vein in the group of pleural thickening.
