ABSTRACT

Objective: This study aimed to evaluate the efficacy and safety of a newly developed, leak closure Internal Compression Therapy (ICT) (Invamed, Ankara, Turkey) device during a single-session procedure in a group of patients with primary deep valve incompetence. Methods: There were 286 patients who were diagnosed with deep venous reflux by duplex scanning. They underwent valvular leak operations to treat primary deep venous insufficiency. Follow-up visits were on the third day, first month, sixth month and twelfth month. At each visit, duplex scanning and a clinical examination were performed. Successful treatment was defined as deep vein valves without reflux. Any patency or reflux over 1 sec was considered a failure. Results: The study enrolled 286 patients with deep venous insufficiency. Procedural technical success was 100%. At the one-year follow-up, the overall success, among all patients, was 92%. No significant morbidity or mortality related to the procedure were observed. All patients had major improvements in venous clinical severity score (VCSS) scores postoperatively. VCSS scores at pre-intervention, and at the twelfth month, were 20.7±5.9 and 3.9±0.9, respectively (p<0.001). Conclusion: After the twelve-month follow-up, the postprocedural outcomes indicate the ICT device is safe and effective.

ABSTRACT

Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining. RA preparation time, RA length/harvesting time ratio, and drainage amounts at the site of RA removal were compared. Results: Differences in RA preparation time (Group 1: 25±6 min, Group 2: 18±3 min, Group 3: 16±3 min, P<0.001) and length/harvesting time ratio (Group 1: 0.76±0.19 cm/min, Group 2: 0.98±0.16 cm/min, Group 3: 1.13±0.09 cm/min, P<0.001) were statistically significant among the groups. Levels of prostacyclin and nitric oxide derivatives were not statistically significant different, VCAM-1 and eNOS expressions were observed to be similar among the groups, and endothelial damage was detected in only one patient per group. Conclusion: Use of ultrasonic cautery during RA preparation considerably reduces the preparation time and postoperative drainage amount. However, the superiority of one method over the others could not be demonstrated when the presence of endothelial damage with both biochemical and histopathological evaluations was considered.

ABSTRACT

PURPOSE: Superficial venous insufficiency is a common problem associated with varicose veins. In addition to classical symptoms, it may result in skin changes, venous ulcers and has a great impact on patients' health-related quality of life. In the last decade, minimally invasive techniques such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) have been developed as alternatives to surgery in an attempt to reduce morbidity and improve efficiency. The aim of this study is to evaluate the efficacy of EVLA and RF therapies in superficial venous insufficiency. MATERIAL AND METHODS: Fifty legs belonging to 50 patients with symptomatic primary venous insufficiency were treated. 25 saphenous veins treated with 1470 nmdiode laser, while 25, saphenous veins treated with bipolar Radiofrequency Induced Thermotherapy (RF). All patients underwent postoperative duplex scanning within 6 month after the procedure and followed clinically, to determine the severity of the venous disease. Complications and occlusion rates were recorded. RESULTS: Total occlusion rates in RF and EVLA groups were 100% and was 100%, respectively. There was no significant difference between groups (p=0,140). Major complications such as skin burns, deep venous thrombosis have not been detected for both groups. 2 patients treated with EVLA had erythema (8%) and 1 patient had a pain sensation (4%). 1 patient in the RF group had erythema (4%), 1 had pain (4%) and 1 had a burning sensation (4%). CONCLUSION: EVLA and RF therapies in saphenous vein insufficiency are effective, minimally invasive, safe, easy to use treatment modalities with good patient satisfaction and high occlusion rates. KEY WORDS: EVLA, Radiofrquency, Venous insufficiency.

ABSTRACT

PURPOSE: The present study aimed to compare the isokinetic muscle strength and range of motion (ROM) values of the ankle between patients diagnosed with C3 chronic venous insufficiency (group 1, n=57) and healthy individuals (group 2, n=30). MATERIALS AND METHODS: After identifying the venous refilling time (VRT) of all participants, the active ROM of the ankle joint and plantar flexion (PF) and dorsi-flexion (DF) muscle strength in the concentric/concentric mode at angular velocities of 60°/sec and 120°/sec were measured. RESULTS: No statistically significant differences were found between the demographic data of groups 1 and 2 (P>0.05). In total, 102 lower extremities were included in group 1 and 60 lower extremities in group 2. The VRT of the patients in group 1 was 15.5±5.6 seconds, the PF ROM of the ankle joint was 39.3°±9.5°, and the DF ROM of the ankle joint was 27°±8°; in group 2, the VRT, PF ROM, and DF ROM were 36±8.1 seconds, 41°±6.2°, and 27.2°±7.5°, respectively. Statistically significant differences were found between the two groups in terms of VRT (P<0.05); however, no statistically significant difference was observed in terms of ankle ROM (P>0.05). Statistically significant difference was found in terms of all parameters of isokinetic muscle strength measurements, such as peak torque, peak torque/body weight, total work done, and ratio (DF/PF) in group 1 (P=0.001). CONCLUSION: The lower extremity muscle strength of patients with chronic venous insufficiency was low, and this weakness was prominent particularly in the direction of PF.

ABSTRACT

Objective This study aims to present the early results of a retrospective study of the use of novel n-butyl-2-cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins. Methods Patients with lower limb venous insufficiency were treated with n-butyl-2-cyanoacrylate (VenaBlock Venous Closure System) between April 2016 and July 2016. The study enrolled adults aged 21-70 years with symptomatic moderate to severe varicosities (C2-C4b) and great saphenous vein reflux lasting longer than 0.5 s with great saphenous vein diameter between 5.5 and 15 mm assessed in the standing position. No compression stockings were used after the procedure. Duplex ultrasound imaging and clinical follow-up were performed on the third day, first month, sixth month, and 12th month. Clinical, etiological, anatomical, pathophysiological classification; venous clinical severity score; and completed Aberdeen varicose vein questionnaire were recorded. Results Five hundred thirty-eight patients with great saphenous vein incompetency underwent n-butyl-2-cyanoacrylate ablation. The mean ablation length was 25.69 ± 4.8 cm, and the average amount of n-butyl-2-cyanoacrylate delivered was 0.87 ± 0.15 ml. The mean procedure time was 11.7 ± 4.9 min. Procedural success was 100%, and complete occlusion was observed after treatment and at the third-day follow-up. We observed ecchymosis in five patients (1.00%) at the entry site at the third-day follow-up. Phlebitis was encountered with six (1.20%) patients. No skin pigmentation, hematoma, paresthesia, deep vein thrombosis, or pulmonary embolism was observed. Kaplan-Meier analysis yielded an occlusion rate of 99.4% at the 12-month follow-up. All patients had significant improvement in venous clinical severity score and Aberdeen varicose vein questionnaire scores postoperatively ( p <0.0001). Venous clinical severity score scores decreased from 5.43 ± 0.87 to 0.6 ± 0.75. Aberdeen varicose vein questionnaire scores decreased from 18.32 ± 5.24 to 4.61 ± 1.42. Conclusions The procedure appears to be feasible, safe, and efficient in treating the great majority of incompetent great saphenous veins with this technique.

ABSTRACT

Objective The aim of this study was to observe the change of the ankle joint range of motion, the muscle strength values measured with an isokinetic dynamometer, pain scores, quality of life scale, and venous return time in chronic venous insufficiency diagnosed patients by prospective follow-up after 12-week exercise program including isokinetic exercises. Methods The patient group of this study comprised 27 patients (23 female, 4 male) who were diagnosed with chronic venous insufficiency. An exercise program including isokinetic exercise for the calf muscle was given to patients three days per week for 12 weeks. At the end of 12 weeks, five of the patients left the study due to inadequate compliance with the exercise program. As a result, control data of 22 patients were included. Ankle joint range of active motion, isokinetic muscle strength, pain, quality of life, and photoplethysmography measurements were assessed before starting and after the exercise program. Results Evaluating changes of the starting and control data depending on time showed that all isokinetic muscle strength measurement parameters, range of motion, and overall quality of life values of patients improved. Venous return time values have also increased significantly ( p < 0.05). Conclusion In conclusion, increase in muscle strength has been provided with exercise therapy in patients with chronic venous insufficiency. It has been determined that the increase in muscle strength affected the venous pump and this ensured improvement in venous function and range of motion of the ankle. In addition, it has been detected that pain reduced and quality of life improved after the exercise program.

ABSTRACT

PURPOSE: The main purpose of this study was to evaluate the influence of any of the four domains of the QoL score in CVD patients of classes C0-C4 and to analyze the correlation between the QoL and types of treatment modalities, and an additional aim of the present study was to compare QoL levels of patients with CVD and healthy participants and was to examine the factors associated with QoL in CVD patients. METHODS: The sample was composed of 501 patients with primary superficial venous reflux (28.5 % male and 71.5 % female) who answered 100 % of the questions in the World Health Organization Quality of Life (WHOQoL-BREF) questionnaire. After a clinical and duplex examination, the patients were categorized as C0-C4, according to the CEAP classification. The relationships between WHOQoL-BREF domains and gender, age, occupation, BMI, the clinical classes of the CEAP classification and four different treatment modalities according to guideline were analyzed. RESULTS: For the WHOQOL-BREF test battery, the patients with CVD had worse values, as compared with the control group participants. The differences were significant for the physical (77.81 ± 12.75 vs. 59.18 ± 12.90, p < 0.001), the psychological (74.78 ± 11.37 vs. 60.21 ± 14.70, p < 0.001), the social relationships (76.56 ± 13.56 vs. 63.07 ± 21.37, p < 0.001) and the environmental (70.27 ± 13.36 vs. 50.16 ± 11.39, p < 0.001) health scores. The patients with CVD had worse WHOQOL-BREF scores at initial, compared with the 6-month follow-up scores. CONCLUSION: This study shows that in spite of undergoing therapy, the subsequent QoL scores did not improve significantly, indicating that CVD continued to negatively affect the patient's life.

ABSTRACT

OBJECTIVE: In this study, the aim was to evaluate the lower extremity muscle strength in patients with chronic venous insufficiency using an isokinetic dynamometer. METHODS: The study comprised a group of 36 lower extremities of 23 patients diagnosed with chronic venous insufficiency and a control group of 40 lower extremities of 20 patients who did not have chronic venous insufficiency. In the diagnosis and evaluation of chronic venous insufficiency, photoplethysmography was used to evaluate the venous return circulation time. Visual Analog Scale scoring was applied to define the level of pain of the patients. Muscle strength measurements were made in all the lower extremities by using an isokinetic dynamometer. RESULTS: A statistically significant difference was detected between the groups in terms of the muscle strength parameters in the ankle plantar flexion, and knee flexor and extensor muscles. However, no statistically significant difference was found between the groups in the ankle dorsiflexion muscle strength parameters. A significant difference was determined in the ratio of ankle dorsiflexion/plantar flexion muscle strength between the mild, moderate and severe venous insufficiency groups. A statistically considerable negative correlation was found between the Visual Analog Scale scores and the photoplethysmography results. According to the Visual Analog Scale results, as the degree of venous insufficiency increased, so did the level of pain. CONCLUSION: Impaired lower extremity muscle strength was observed in chronic venous insufficiency patients. Although the current study was consistent with literature in respect of impaired calf muscle strength, this finding was also seen in the thigh muscles. Furthermore, we concluded that if venous insufficiency becomes more severe, impaired calf muscle strength becomes more evident.
