Superficial Venous Insufficiency

BACKGROUND: Endovenous laser ablation is a minimally invasive procedure that can be used to treat superficial venous insufficiency. We believe that using a longer wavelength will reduce the frequency of the most common adverse effects associated with the use of shorter wavelengths.OBJECTIVES: To report the results of an initial series of patients with chronic superficial venous insufficiency treated using a 1470 nanometer diode laser and to compare results using linear and radial laser fibers.METHODS: We conducted an observational cohort study. Seventy-four patients, for whom at least two postoperative Doppler ultrasonography scans were available, were recruited with a total of 121 saphenous veins treated (92 great and 29 small saphenous veins). There were 57 patients in Group A (treated with the linear fiber) and 17 in Group B (radial fiber). Follow-up ideally comprised clinical consultation and Doppler ultrasonography at 1 month, 6 months and 12 months after the procedure. Success was defined as total occlusion of the venous segment that had been treated.RESULTS: Success rates at mean follow-up of 13.4 months (range 7 - 27) were 83% for great saphenous veins and 89% for small saphenous veins. Patients treated with the radial fiber required less energy to achieve occlusion of the small saphenous vein and exhibited fewer adverse reactions, with statistical significance.CONCLUSIONS: Treatment of great and small saphenous vein insufficiency using the 1470 nm diode laser is safe and effective. The radial fiber was associated with fewer intercurrent conditions than the linear fiber, although success rates were similar.

Background: Endovenous laser ablation is one of the most accepted treatment options for insufficient great and small saphenous veins. The aim of this study was to investigate the long-term efficacy and safety of the radial fiber (ELVeS-radial kit™) for the 1470 nm diode laser in a 1-year follow-up. Methods: A total of 308 lower limbs with primary insufficiency of great and small saphenous veins or insufficient tributaries were included in the prospective observational cohort study. The primary efficacy endpoint of the study was ultrasonographic proven elimination of venous reflux after at least 1 year. Secondary efficacy and further safety end points after 1 year were as follows: (1) sonographic exclusion of recanalization of the treated vein segments, (2) deep vein thrombosis, clinical pulmonary embolism or superficial vein thrombosis as defined by objective testing, (3) death from any cause, (4) persistent clinical complaints such as pain and paresthesia, (5) recurrent varicose veins. Patient satisfaction was assessed using a CIVIQ-2 questionnaire after 1 year. Results: Follow-up could be completed in 91.2% of the patients. Excellent efficacy numbers with 99.6% occlusion of the treated varicose veins as elimination of reflux could be demonstrated. After 1 year, 96% of the treated veins disappeared completely sonographically; one recanalization was observed. No deep vein thrombosis or pulmonary embolism occurred, three superficial vein thrombosis were diagnosed in follow-up examinations. Four patients died, not related to pulmonary embolism. No persistent pain or paresthesia occurred in the follow-up. Recurrent varicose veins were diagnosed in 10 patients (2.81%). Conclusion: One-year follow-up showed that endovenous laser treatment of varicose veins with 1470 nm diode laser using the radial fiber is highly effective, also regarding in a 1-year follow-up.

Objective the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III. Methods retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success. Results A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%. Conclusions MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.

Total Occlusion

The reverse CART technique provides the potential to modify the retrograde procedure by improving the controlled movement of the retrograde wire and improve the success rates of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Development of interventricular hematoma is a rare complication of CTO PCI. A 63-year-old man with effort angina with a right coronary artery CTO lesion underwent PCI by retrograde approach from the LAD to a septal branch. A contrast “stain” was demonstrated surrounding the septal collateral channel used for the retrograde approach at the end of the procedure without symptom. Echocardiography indicated an increased interventricular septum thickness with low echo signals region and decreased contractility. Cardiac magnetic resonance (CMR) imaging using gadolinium showed a diffusely thickened septum with a low signal fusiform neocavitation delimited by an enhanced-signal ring suggesting intraventricular septal dissecting hematoma. After conservative treatment, follow-up echocardiogram and CMR showed the resolution of the hematoma without clinical events. This case highlights the potentially lethal complication of septal perforator dissection and hematoma that may cause severe myocardial injury caused by retrograde approach for CTO PCI.

Objective To review clinical outcomes of varicose vein patients treated with cyanoacrylate embolization and radiofrequency ablation at our institution. Methods A retrospective review of patients who underwent cyanoacrylate embolization and radiofrequency ablation during a three-year period. Patient records were reviewed to assess demographics, location and severity of disease, treatment details and outcome at short- and mid-term follow-ups. Outcome parameters included treatment success and complications. Results Between January 2014 and December 2016, 335 patients with 476 veins were treated with either cyanoacrylate embolization (n = 148) or radiofrequency ablation (n = 328) at the Vancouver General Hospital Vascular Surgery Vein Clinic. The average age of patients were 57 ± 1 years with the majority being female (78%) and an average BMI of 24.8 ± 0.5. CEAP classes were 2 (49%), 3 (26%), 4a (22%) and >4b (3%). Of the veins treated with cyanoacrylate embolization, the vein types were as follows: 76% were great saphenous vein, 16% were small saphenous vein, 5% were anterior accessory great saphenous vein and 1.4% were perforator veins. The vein types for radiofrequency ablation were 88%, 9%, 3% and 0%, respectively. The average amount of cyanoacrylate embolization delivered for great saphenous vein treatment was 1.8 ± 0.1 ml with a treatment length of 43 ± 1 cm. Subgroup comparison was done for great saphenous vein segments. Treatment success was 100% in cyanoacrylate embolization and 99% in radiofrequency ablation. Superficial phlebitis was the most common complication noted at mid-term follow-up in 5% of cyanoacrylate embolization and 16% of radiofrequency ablation treatments (P < 0.05). One patient in each group had asymptomatic proximal thrombus extension treated with anticoagulation for 2–3 weeks. Three superficial infections from glue clumps were noted in the cyanoacrylate embolization group requiring excision and drainage. Five patients in the radiofrequency ablation group had persistent numbness and one wound complications at the access site. Conclusion Cyanoacrylate embolization offers equivalent success rates with lower mid-term complication rates as radiofrequency ablation.

Objectives The aim of this prospective single-centre study is to assess the effectiveness and patient experience of the VenaSeal™ Closure System, a novel non-thermal, non-tumescent catheter technique, which uses cyanoacrylate glue to occlude the refluxing truncal superficial veins to treat varicose veins and chronic venous insufficiency, in a multi-ethnic Asian population from Singapore. Methods Seventy-seven patients (93 legs; 103 procedures) underwent VenaSeal™ Closure System ablation. Forty-nine (63.6%) for great saphenous vein incompetence, 16 (20.8%) bilateral great saphenous vein, 2 (2.6%) small saphenous vein and 10 (13.0%) combined unilateral great saphenous vein and small saphenous vein/anterior thigh vein reflux. In addition, 65/93 legs (69.9%) had C4–C6 disease. Patients were reviewed at 2 weeks, 3, 6 and 12 months post-procedure. Results There was 100% technical success. 28/77 (36.4%) underwent concomitant phlebectomies. All procedures were well tolerated with a mean post-operative pain score of 3.0 (range: 0–5). After three months, median patient satisfaction was 9.0 (interquartile range: 7.0–10.0). At two-week follow-up, the great saphenous vein was completely occluded in 88/88 (100%) veins and small saphenous vein completely closed in 11/11 (100%) veins. At three-month follow-up, the great saphenous vein was occluded in 51/53 (96.2%) veins and small saphenous vein completely closed in 5/5 (100%) veins. At six-month follow-up, the great saphenous vein was completely occluded in 42/45 (93.3%) veins and small saphenous vein completely closed in 5/7 (71.4%) veins. At one year, great saphenous vein and small saphenous vein occlusion rates were 54/59 (91.5%) and 5/8 (62.5%), respectively. There was one deep vein thrombosis. Transient superficial phlebitis was reported in 10/93 (10.8%) legs, which were all self-limiting. There were 9/103 (8.7%) anatomical recurrences, but no patients required re-intervention as they were asymptomatic. Conclusions Cyanoacrylate glue is a safe and efficacious modality to ablate refluxing saphenous veins in Asian patients in the short term. There is a high satisfaction rate and peri-procedural pain is low. Early results are promising but further evaluation and longer term follow-up are required.

Aims To report on great saphenous vein diameter distribution of patients undergoing endovenous laser ablation for lower limb varicose veins and the ablation technique for large diameter veins. Methods We collected retrospective data of 1929 (943 left leg and 986 right leg) clinically incompetent great saphenous vein diameters treated with endovenous laser ablation over five years and six months. The technical success of procedure, complications and occlusion rate at short-term follow-up are reported. Upon compression, larger diameter veins may constrict asymmetrically rather than concentrically around the laser fibre (the ‘smile sign’), requiring multiple passes of the laser into each dilated segment to achieve complete ablation. Results Of 1929 great saphenous veins, 334 (17.31%) had a diameter equal to or over 15 mm, which has been recommended as the upper limit for endovenous laser ablation by some clinicians. All were successfully treated and occluded upon short-term follow-up. Conclusion We suggest that incompetent great saphenous veins that need treatment can always be treated with endovenous laser ablation, and open surgery should never be recommended on vein diameter alone.

Objective: To find out if there is a relation among the diameter of the great saphenous vein (GSV) when it is incompetent, the clinical gravity of the varicose syndrome and the type of insufficiency of the saphenofemoral junction (SFJ) in patients with chronic venous insufficiency (CVI) by means of duplex exploration. Methods: The sample included 145 extremities, 38 normal as a control group and 107 with incompetence of the GSV. According to the results of the Valsalva and Parana manoeuvres in the SFJ, they were distributed into four groups. The diameter of the GSV and the clinical state according to the clinical, aetiological, anatomical and pathological element classification were recorded for each group. Results: Statistically significant differences were obtained for the diameter and the clinical state in patients with positive manoeuvres with regard to other groups. The diameter was greater and the clinical state more severe (C4, C5 and C6) when two manoeuvres were positive. Conclusions: The presence of both positive manoeuvres in the SFJ is related to severe clinical states and greater diameters of the GSV, allowing the establishment of a prognosis of the CVI and the most suitable surgical approach.
