Objective To evaluate the diagnostic value of the mammography and to raise the level of preoperative diagnosis.Methods The mammography of 139 cases were analyzed and the result was compared with that of pathology.Results The sensitivity was 91.43%, the specificity was 95.65%, the positive predictive value was 95.52%, the negative predictive value was 91.67%; the positive likelihood ratio was 21.03, and the negative likelihood ratio was 0.09; the false positive value and the false negative value were 4.3% and 8.6% respectively.Conclusion The signs of the most malignancy of breast can be shown by mammography. And the technique has very high value of the determinative diagnosis to be applied further.

Objective To evaluate the clinical application of superselective renal artery embolization for the treatment of traumatic renal hemorrhage. Methods Thirty eight patients with traumatic renal hemorrhage were first demonstrated by renal arterigraphy under seldinger technique to ensure the rupture site and degree of renal artery and then followed by percutaneous cathetherized superselective renal arterial embolization through guidance of super slippery guide wire with gelfoam particles or steel coil. Results All 38 patients revealed occlusive abruption of bleeding arteries and disappearance of vextravasation staining after the superselective catheterized renal arterial embolization with gelfoam particles and steel spring coil under DSA. Clinically, all patients urine turned clear without macroscopic hematuria during 1 - 3 days after the procedure. Conclusions Superseclective renal arterial embolization is less aggressive and simultaneously with less complications, good hemostatic efficacy, maximal preservation of renal tissue and function for renal traumatic hemorrhage, which is worthy to be recommended.
