High frequency ultrasound imaging as a "potential" way of evaluation modality in side effects of lip augmentation - case report.

Lip augmentation is a popular procedure performed by esthetic medicine doctors, however, it is associated with a significant number of side effects. High frequency ultrasound imaging helps with diagnosis of side effects.The patient was 43-year-old healthy female, 8 months after lip augmentation.The examination showed a variety of delayed side effects of lip augemntation. Ultrasound imaging revealed an increased echogenicity of lip soft tissue, too deep filler injection, occlusion of the inferior labial artery.

Comparative analysis of five-year outcomes of lower extremity varicose vein therapy using monopolar and segmental radiofrequency ablation.

BACKGROUND: To compare efficacy and safety of segmental and monopolar radiofrequency ablation in the management of lower extremity varicose veins. METHODS: A total of 193 patients were treated with segmental RF ablation (Venefit; N.=97) or monopolar RF ablation (EVRF; N.=96) for lower extremity varicose veins from 2010 to 2012. A single extremity of each patient with isolated GSV or SSV insufficiency was enrolled. The differences between the two groups in demographic parameters, disease severity, treated veins, peri- and postoperative complications, and treatment efficacy indicators (VCSS) were evaluated. RESULTS: Based on Kaplan-Meier's analysis, the occlusion rate after 5 years was 87.6% in Venefit group and 87.8% in EVFR group (P>0.05). Varicose vein recurrence rates were 10.3% and 12.9% in the Venefit and EVFR groups, respectively (P>0.05). The VCSS reduction was comparable between the two groups (P<0.05). CONCLUSIONS: Venefit and EVRF systems can be considered equivalent in terms of efficacy and safety in the management of lower extremity varicose veins.

Complications and Failure of Endovenous Laser Ablation and Radiofrequency Ablation Procedures in Patients With Lower Extremity Varicose Veins in a 5-Year Follow-Up.

INTRODUCTION: Thermal ablation techniques have gradually replaced Babcock procedure in varicose vein treatment. AIM: A comparative quantitative-qualitative analysis of complications and failure of endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) in a 5-year follow-up. MATERIALS AND METHODS: One hundred ten adult participants with varicose veins clinical grade C2 to C6, treated for isolated great saphenous vein (GSV) or small saphenous vein (SSV) insufficiency in a single lower extremity in 2009 to 2010, were enrolled and subdivided into EVLA (n = 56) and RFA (n = 54) groups. Both groups were compared for demography, disease stage, affected veins, perioperative, and postoperative complications as well as treatment efficacy. RESULTS: The perioperative and postoperative complications were statistically insignificant. Treatment efficacy, expressed as the number of participants with recurrent varicosity and recanalization, was comparable in both groups. The clinically significant recanalization rate was 3.6% and 5.6% in EVLA and RFA groups, respectively. CONCLUSION: Endovenous laser ablation and RFA for the management of lower extremity varicose vein offer comparable efficacy and safety in a 5-year follow-up.

Shear wave elastography may add a new dimension to ultrasound evaluation of thyroid nodules: case series with comparative evaluation.

Although elastography can enhance the differential diagnosis of thyroid nodules, its diagnostic performance is not ideal at present. Further improvements in the technique and creation of robust diagnostic criteria are necessary. The purpose of this study was to compare the usefulness of strain elastography and a new generation of elasticity imaging called supersonic shear wave elastography (SSWE) in differential evaluation of thyroid nodules. Six thyroid nodules in 4 patients were studied. SSWE yielded 1 true-positive and 5 true-negative results. Strain elastography yielded 5 false-positive results and 1 false-negative result. A novel finding appreciated with SSWE, were punctate foci of increased stiffness corresponding to microcalcifications in 4 nodules, some not visible on B-mode ultrasound, as opposed to soft, colloid-inspissated areas visible on B-mode ultrasound in 2 nodules. This preliminary paper indicates that SSWE may outperform strain elastography in differentiation of thyroid nodules with regard to their stiffness. SSWE showed the possibility of differentiation of high echogenic foci into microcalcifications and inspissated colloid, adding a new dimension to thyroid elastography. Further multicenter large-scale studies of thyroid nodules evaluating different elastographic methods are warranted.
