Conclusion:As seen in our large series study, PNL is a highly effective and safe procedure that can be applied to the obese patients.

Objective: superficial venous insufficiency is a common problem associated with varicose veins which, if untreated, may progress to venous ulceration. Endovenous laser ablation (Evla) is a new, minimally invasive method for management of superficial venous insufficiency and varicose veins. the aim of this study was to demonstrate the effectiveness of 980 nm Evla for treatment of symptomatic saphenous venous insufficiency and to present its early outcomes. Methods: thirty-eight great saphenous veins and 5 small saphenous veins in 40 patients with saphenofemoral reflux were treated with 980 nm diode endovenous laser equipment. the diameter and length of the vein treated, total laser energy and energy density (Joules/cm) delivered were recorded. to determine the severity of the venous disease venous clinical severity score (vcss) and visual analogue scale (vas) were used. Patients were followed up for 6 months after the procedure. complications were recorded prospectively. Results: forty-three saphenous veins in 40 patients were treated. the mean age of the patients was 39.9 (range 21-72) years. the mean diameter and length of the veins were 4.9 mm (range, 3.5 to 8.5 mm) and 30.2 cm (range, 16 to 50 cm), respectively. at 6 months follow-up, total occlusion rate was 95.4% (41/43), and recanalization rate was 4.6%. significant decrease was observed for vcss and vas scores after the procedure. no major complication was detected. Conclusion: Evla treatment for superficial venous insufficiency is safe and can be carried out under local anaesthesia in an outpatient setting with good patient satisfaction and low complication rates.

ÖZET:Postmenopozal over kitlelerinde spektral doppler ultrason parametrelerinin preoperatif değerlendirmesi Amaç: Bu çalışmanın amacı postmenopozal kadınlarda görülen over tümörlerinde kantitatif spektral Doppler ultrasonografi (DUS) akım ölçümlerini değerlendirmektir. Gereç ve Yöntem: Bu prospektif çalışmaya preoperatif over tümörü tanısı alan 23 postmenopozal kadın dahil edildi. Hastalar operasyondan 2-4 gün öncesinde transvajinal DUS ile incelendi. Ovaryen tümörlerdeki akımlarda rezistans indeks (Rİ) ve pulsatilite indeksi (Pİ) transvajinal DUS ile değerlendirildi. Bulgular: Cerrahi sorası yapılan histopatolojik incelemede kitelerin 8'i malign, 13'ü benign ve 1'i borderline tümör olarak belirlendi. Malign tümörler için ortalama Rİ ve Pİ sırasıyla 0.37 (0.35-0.45) ve 0.61 (0.43-0.85) idi. Benign tümörler için ortalama Rİ ve Pİ sırasıyla 0.61 (0.30-0.91) ve 1.21 (0.36-3.02) idi. Ki-kare testinde DUS ölçümleri ve histopatolojik sonuçlar arasında istatistiksel olarak anlamlı (p<0.05) korelasyon saptandı. Malign lezyonları saptamada 0.4'ten küçük Rİ için; duyarlılık, özgüllük, pozitif ve negatif prediktif değerleri sırasıyla %77, %85, %77 ve %85; 0.7'den küçük Pİ için; duyarlılık, özgüllük, pozitif ve negatif prediktif değerleri sırasıyla %77, %78, %70 ve %84 olarak hesaplandı. Sonuç: Kantitatif transvajinal DUS akım ölçümleri postmenopozal kadınlarda malign over tümörlerinin benign over tümörlerinden ayrımında duyarlı ve özgül sonuçlar sağlar.

Material and Method: This prospective study included 23 postmenopausal women with preoperative diagnosis of ovarian tumor. Patients were examined with transvaginal DUS 2 to 4 days before surgery. The resistive index (RI) and pulsatility index (PI) of the mass were evaluated by transvaginal DUS examination.Results: The histopathologic examination of the surgical specimens revealed 8 malignant, 13 benign and 1 borderline tumor. The mean RI and PI for malignant tumors were 0.37 (range 0.35-0.45) and 0.61 (range 0.43-0.85), respectively. The mean RI and PI for benign tumors were 0.61 (range 0.30-0.91) and 1.21 (range 0.36-3.02), respectively. The Mann-Whitney U test revealed a statistically significant (p<0.05) correlation between the DUS measurements and histopathologic results. The sensitivity, specificity, positive and negative predictive cut-off values for RI less than 0.4 was 77%, 85%, 77%, and 85% respectively, in the diagnosis of malignant lesions. The sensitivity, specificity, positive and negative predictive cut-off values for PI less than 0.7 was 77%, 78% 70%, and 84% respectively. Conclusion: Quantitative transvaginal DUS flow measurements provides sensitive and specific results in differentiating be...
