A new non-tumescent endovenous ablation method for varicose vein treatment: Early results of N-butyl cyanoacrylate (VariClose®)

Objective This report aims to present the early results of a retrospective study of the use of N-butyl cyanoacrylate (VariClose®)-based non-tumescent endovenous ablation for the treatment of patients with varicose veins. Method One hundred and eighty patients with varicose veins due to incompetent saphenous veins were treated with the VariClose® endovenous ablation method between May 2014 and November 2014. The patient sample consisted of 86 men and 94 women, with a mean age of 47.7 ± 11.7 years. The patients had a great saphenous vein diameter greater than 5.5 mm and a small saphenous vein diameter greater than 4 mm in conjunction with reflux for more than 0.5 s. Patients with varicose veins were evaluated with venous duplex examination, Clinical, Etiological, Anatomical and Pathophysiological classification (CEAP), and their Venous Clinical Severity Scores were recorded. Results The median CEAP score of patients was three, and the saphenous vein diameters were between 5.5 and 14 mm (mean of 7.7 ± 2.1 mm). A percutaneous entry was made under local anesthesia to the great saphenous vein in 169 patients and to the small saphenous vein in 11 patients. Duplex examination immediately after the procedure showed closure of the treated vein in 100% of the treated segment. No complications were observed. The mean follow-up time was 5.5 months (ranging from three to seven months). Recanalization was not observed in any of the patients during follow-up. The average Venous Clinical Severity Scores was 10.2 before the procedure and decreased to 3.9 after three months (p < 0.001). Conclusion The application of N-butyl cyanoacrylate (VariClose®) is an effective method for treating varicose veins; it yielded a high endovenous closure rate, with no need for tumescent anesthesia. However, long-term results are currently unknown.

Comparison of Endovenous Laser and Radiofrequency Ablation in Treating Varicose Veins in the Same Patient

Purpose: To compare endovenous laser ablation (EVLA) and radiofrequency venous ablation (RFA) in different legs in the same patients with venous insufficiency. Methods: Sixty patients with bilateral saphenous vein insufficiency were included. Endovenous laser ablation or RFA was applied to one of the patient’s legs and the remaining procedure, RFA or EVLA, to the other leg. Results: Minor complications in EVLA and RFA were hyperemia at 20.7% and 31.0%, ecchymosis at 31.0% and 51.7% and edema at 27.6% and 65.5%, respectively. The rate of recanalization was 6.8% in the RFA group. No recanalization was observed in the EVLA group. The level of patients satisfied with EVLA was 51.7%, compared to 31.0% for RFA, while 17.2% of patients were satisfied with both the procedures. Times to return to daily activity were 0.9 days in the EVLA group and 1.3 days in the RFA group. Conclusion: The EVLA procedure may be superior to RFA in certain respects.

Which prosthesis is more resistant to vascular graft infection: polytetrafluoroethylene or Omniflow II biosynthetic grafts?

PurposeThe aim of this study was to determine whether polytetrafluoroethylene grafts or Omniflow II biosynthetic grafts are more resistant to infection caused by Staphylococcus aureus.MethodsSixty rats were divided into six groups. In Groups 1A, 1B and 1C, a polytetrafluoroethylene graft was implanted in each rat, and, in Groups 2A, 2B and 2C, a biosynthetic graft was implanted in each rat. Staphylococcus aureus was inoculated into Groups 1B, 1C, 2B and 2C, and the rats in Groups 1C and 2C were treated with teicoplanin. One week later, the rats were euthanized, the grafts were removed and a microbiological count was performed. A histopathological examination was subsequently carried out, and the C-reactive protein, prealbumin and leukocyte levels were investigated.ResultsThere were no significant differences in the C-reactive protein, prealbumin and leukocyte levels. The differences in the results of the microbiological evaluations between the groups were significant. The quantitative culture results showed no bacterial growth in Groups 1A, 1C and 2A. The number of bacteria in Group 1B was statistically lower than that in Group 2B. When the groups receiving treatment were compared, Group 2C had bacterial growth, whereas Group 1C did not. The histopathological examinations showed similar results.ConclusionsOmniflow II grafts are more susceptible to infection than polytetrafluoroethylene grafts.

Efficacy of Linezolid, Teicoplanin, and Vancomycin in Prevention of an Experimental Polytetrafluoroethylene Graft Infection Model caused by Methicillin-Resistant Staphylococcus aureus

Background The aim of this study was to evaluate the effectiveness of linezolid, teicoplanin, and vancomycin in prevention of prosthetic vascular graft infections in a vascular graft infection model. Material/Methods Fifty rats were divided into 5 groups. A polytetrafluoroethylene graft was implanted on the back of each rat. Methicillin-resistant Staphylococcus aureus (MRSA) strain was inoculated into all rats except Group 1. Group 2 was not given any treatment, Group 3 received linezolid, Group 4 received vancomycin, and Group 5 received teicoplanin. The grafts were removed for microbiological and histological examinations on the 7th day. In addition, C-reactive protein and prealbumin levels and leukocyte counts in obtained blood specimens were determined. Results Group 1 did not have infection. Group 2 had bacteria 5.7×104 CFU/cm2. Group 3 and Group 4 had less bacterial growth. Group 5 had no bacterial growth. The number of bacteria was significantly higher in Group 2 than in the other experimental groups and the control group (p<0.001). Although there was no bacterial growth in Group 5, it did not significantly differ from Group 3 and Group 4. Group 2 had a significantly higher CRP level and leukocyte count and a significantly lower prealbumin level than the other groups. Conclusions Linezolid, teicoplanin, and vancomycin are effective in prevention of prosthetic vascular graft infections.

Evaluation of left atrial mechanical function and atrial conduction abnormalities in Maras powder (smokeless tobacco) users and smokers.

Summary Objective In Turkey, a type of smokeless tobacco called Maras powder (MP) is widely used in the south-eastern region. Smokeless tobacco is found in preparations for chewing and for absorption by the nasal and oral mucosae. The purpose of this study was to investigate whether MP damages intra- and inter-atrial conduction delay and left atrial (LA) mechanical function as much as cigarette smoking. Method A total of 150 chronic MP users (50 males, 32.5 ± 5.4 years), smokers (50 males, 32.1 ± 6.0 years) and controls (50 males, 30.1 ± 5.8 years) were included in the study. LA volumes were measured echocardiographically according to the biplane area–length method. Atrial electromechanical coupling was measured with tissue Doppler imaging and LA mechanical function parameters were calculated. Results The LA passive emptying fraction was significantly decreased and LA active emptying volume (LAAEV) was significantly increased in the MP group (p = 0.012 and p = 0.024, respectively), and the LA active emptying fraction (LAAEF) was significantly increased in the smokers (p = 0.003). There was a positive correlation between the amount of MP used and smoking (pack years) with LAAEV and LAAEF (r = 0.26, p = 0.009 and r = 0.25, p = 0.013, respectively). Lateral atrial electromechanical intervals (PA) were significantly higher in MP users, and the septal mitral PA was statistically higher in the smokers (p = 0.05 and p = 0.04, respectively). Conclusion We suggest that atrial electromechanical coupling intervals were prolonged and LA mechanical function was impaired in MP users and smokers, but there was no significant difference between the MP users and smokers. These findings may be markers of subclinical cardiac involvement and tendency for atrial fibrillation.

Infective endocarditis developing serious multiple complications

A 20-year-old female patient with no history of heart disease presented to the hospital with high fever, cough and sputum. On the third day of hospitalisation, left facial paralysis developed and cranial revealed an infarct in the right frontoparietotemporal lobe. Transthoracic echocardiography revealed 1.5×2 cm-sized vegetation on the mitral valve and severe mitral regurgitation. On the 11th day of hospitalisation, multiple emboli were shown to be present in the left iliac artery. Since the patient had recurrent septic emboli despite 3 weeks of treatment, a surgical intervention was planned. The vegetation was removed and the mitral valve was replaced by mechanical prostheses. During the postoperative period, acute renal failure developed in the patient. The treatment was completed in 6 weeks with full recovery. This case confirms that infective endocarditis may present with various clinical situations, and that a high index of suspicion and surgical intervention, in addition to aggressive antibiotic therapy, is lifesaving.
