Materials and Methods: Medical records of 49 patients (35 female, 14 male) with isolated saphenous venous insufficiency were reviewed. Endovenous laser ablation was performed in all patients at an emission wavelength of 1470 nm, using 7 Watt laser energy at the proximal and distal ports. The pain was evaluated using a visual analog scale at 7 days, 1, 3 and 6 months. Results: In 30 of the 49 patients, vascular access was performed from the distal to the below the knee section of the small saphenous vein and in 19 cases from proximal to the small saphenous vein. The results of these two groups showed that access into the larger proximal part of the varicose vein provides an easy route with reduced local pain scores in the endovenous laser ablation of varicose veins (p<0.001). Conclusion: In patients diagnosed with isolated varicose small saphenous vein and undergoing endovenous laser ablation, the vascular access route (proximal or distal) did not have a significant effect on postoperative pain, but the proximal route was more easily accessed and the procedure lasted shorter.

Vocal cord mobility of 44 patients (36 men; age range, 49-81 years) with larynx cancer was examined; 13 patients were excluded (owing to poor image quality or bilateral vocal cord involvement), and vocal cord mobility was evaluated for the remaining 31 patients qualitatively and quantitatively with dynamic laryngeal computed tomography during phonation, inspiration, and Valsalva maneuver phase. The mobile cords were laterally positioned in a straight configuration on inspiration phase. Phonation phase images revealed medial displacement with protrusion of the cords (shoulder sign) and ventricular niche (31 patients/42 cords). Fixed cords (13 patients/13 cords) conserved their configuration and location during all phases. The distances of the vocal cords to the midline were measured based on the images obtained during inspiration and Valsalva maneuvers. The mean ± SD difference between the movement distances of cords measured during each phase was as follows: 6.16 ± 1.64 mm for the mobile cord (n = 42) and 3.17 ± 0.78 mm for the impaired cord (n = 7) on the midcoronal plane (P = 0.0001). A comparison between the mean distance values of the mobile, impaired and fixed cords groups revealed significant distance. Dynamic laryngeal computed tomography of the larynx of patients with laryngeal cancer can be used as a supplemental tool to examine cord mobilization for accurate T-staging (particularly for patient laryngoscopy, which is difficult to perform), and can provide additional information to physicians.

To evaluate the efficiency, complications, safety and clinicopathological utility of ultrasonographic-guided percutaneous liver biopsy in diffuse liver disease. In our retrospective study, we evaluated ultrasound-assisted needle biopsies that were performed in outpatients from October 2006 to July 2010. The liver biopsies were performed following one-night fasting using the tru-cut biopsy gun (18-20 gauge) after marking the best seen and hypovascular part of the liver, distant enough from the adjacent organs. A total of 1018 patients were referred to our radiology department. Most of the patients had hepatitis B (60.6%). The biopsy specimens were recorded and sent to our pathology department for histopathological examination. According to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely....

The aim of the present study was to propose the angled tangential approach technique for real-time ultrasound-guided pediatric percutaneous renal biopsy. A retrospective analysis of 166 percutaneous biopsies from June 2004 to May 2009 was performed. Patients' medical records, pathology results, and complications were reviewed. No major complications were seen in the study group. The most frequently occurring minor complication was macroscopic hematuria, which occurred at the rate of 9.6%. Hematoma was detected in three cases and regressed spontaneously in all cases. The angled tangential approach is a safe technique and an alternative option in pediatric percutaneous renal biopsies.

A total of 56 patients clinically diagnosed with varicocele were randomized into two groups: 28 were selected for high-ligation surgery and 28 for microsurgery. The testicular blood flow was evaluated in all patients before and 7 days after surgery, and the maximal flow velocity (Vmax), minimal flow velocity, and resistive index were measured. The data assessment was performed using the paired t test, and independent t test was used in comparison of the two groups. No significant difference was detected between the preoperative resistive index, Vmax, and minimal flow velocity of the two groups. The values of the same parameters measured 7 days postoperatively were also not significantly different. The preoperative and postoperative comparison of the three parameters within the microsurgery group revealed no difference, although the postoperative Vmax was significantly lower than the preoperative Vmax in the high-ligation group. Our data have shown that no significant impairment in testicular circulation results after low microsurgical varicocele repair compared with high ligation.

The liver biopsies were performed following one-night fasting using the tru-cut biopsy gun (18-20 gauge) after marking the best seen and hypovascular part of the liver, distant enough from the adjacent organs. A total of 1018 patients were referred to our radiology department. Most of the patients had hepatitis B (60.6%). The biopsy specimens were recorded and sent to our pathology department for histopathological examination. According to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely....

The aim of the present study was to propose the angled tangential approach technique for real-time ultrasound-guided pediatric percutaneous renal biopsy. A retrospective analysis of 166 percutaneous biopsies from June 2004 to May 2009 was performed. Patients' medical records, pathology results, and complications were reviewed. No major complications were seen in the study group. The most frequently occurring minor complication was macroscopic hematuria, which occurred at the rate of 9.6%. Hematoma was detected in three cases and regressed spontaneously in all cases. The angled tangential approach is a safe technique and an alternative option in pediatric percutaneous renal biopsies.

A total of 56 patients clinically diagnosed with varicocele were randomized into two groups: 28 were selected for high-ligation surgery and 28 for microsurgery. The testicular blood flow was evaluated in all patients before and 7 days after surgery, and the maximal flow velocity (Vmax), minimal flow velocity, and resistive index were measured. The data assessment was performed using the paired t test, and independent t test was used in comparison of the two groups. No significant difference was detected between the preoperative resistive index, Vmax, and minimal flow velocity of the two groups. The values of the same parameters measured 7 days postoperatively were also not significantly different. The preoperative and postoperative comparison of the three parameters within the microsurgery group revealed no difference, although the postoperative Vmax was significantly lower than the preoperative Vmax in the high-ligation group. Our data have shown that no significant impairment in testicular circulation results after low microsurgical varicocele repair compared with high ligation.
