Objective To evaluate the value of metal spring ring for localization of breast lesions. Methods Thirteen cases of nonpalpable breast benign lesion and 41 cases of breast cancer that had been treated by neoadjuvant chemotherapy were enrolled in this study. The lesion was localized with the margin being marked under the guidance of ultrasonography. Metal spring rings with proper length was used according to the maximum diameter of the lesion; and then via a 18G puncture needle, the metal spring ring was place exactly to the two ends of the biggest cross-section of the lesion by using a guide wire. Afterwards, the lesions were resected with the spring ring. The 41 patients with breast cancer received 2-to 3-week chemotherapy after the operation. Results For the 13 cases of benign breast lesion, the mass was resected accurately and completely with the spring rings. In the 41 cases of breast cancer, no residual tumor cells were found in the tissues around the margin of resection. During the postoperative chemotherapy, ultrasonography showed that the mass was reduced in 39 of the cases, among which 9 had no clear margin of the tumor before the operation shown by ultrasonography. Off the 9 cases, postoperative pathological examination found no tumor cells in the successive sections. Conclusions Localization of breast lesions under the guidance of ultrasonography is a new method for diagnosis and treatment of nonpalpable breast lesions. It is valuable for follow-up by ultrasonography, evaluation of chemotherapy, and postoperative biopsy, especially for the breast cancer patients who have received preoperative chemotherapy.

Objective To assess the clinical value of ultrasound-guided popliteal vein puncture in the treatment of lower extremity deep venous thrombosis.Method We performed ultrasound-guided catheterization through popliteal vein in 71 patients with lower extremity deep venous thrombosis who were supposed to receive catheter-directed thrombolysis.Results Catheter sheathes were successfully inserted in 69 patients.No severe complication was observed.and a good curative effect after the treatmeut of thrombolysis and anticoagulation was found.Insertions of guide-wires failed in 2 patients because of organizatioo of the thrombus.Conclusion Ultrasound-guided popliteal vein puncture is safe and easy to operate,and is worth popularizing.

ObjectiveOne hunred and twenty-four To probe into application value of ultrasound guided Catheterization in internal jugular vein. MethodsOne hundrel and twenty-four guided by ultrasound puncture holder, single-channel or three-channel catheter was embedded into jugular vein. ResultsThe catheter was inserted successfully by only one procedure in all the 124 patients. There was no complication. ConclusionsThe catheterization becomes safer, convenient and quickly with ultrasound puncture holder guidance, decreasing failure rate and complication of the procedure.

Objective To investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.

Objective To evaluate the value of contrast-enhanced uhrasound(CEUS)for liver fibrosis.Methods Ninty-two chronic hepatitis B patients with histology diagnosis and fifteen health control were detected by CEUS,dynamic images and the time-intensity curve were analyed.Results Hepatic veinartery transit(HV-ATT)became shorter in the early hepatic cirrhosis patients [(7.5±2.1)s]compared to the control[(11.8±2.7)s].However,there was no difference between the fibrosis patients [(13.0±2.2)s]and the control.Furthermore,HV-ATT of the fibrosis patients with S1 to S3 stage were(11.7±2.7)s(S1),(11.8±3.0)S(S2),(11.8±2.3)s(S3)without significant difference.Conclusions CEUS is valuable in diagnosing earlier hepatic cirrhosis,but not fibrosis.
