A randomized controlled trial found that surgery "reduces the recurrence of ulcers at four years and results in a greater proportion of ulcer free time". Local anaesthetic endovenous surgery using the thermoablation (endovenous laser ablation or radiofrequency), perforator closure (TRLOP) and foam sclerotherapy showed an 85% success rate of healing, with no recurrence of healed ulcers at an average of 3.1 years, and a clinical improvement in 98% in a selected group of venous leg ulcers. No studies are found on the effect of endovenous thermal ablation on ulcer healing, recurrence, and quality of life. The use of subfascial endoscopic perforator surgery is uncertain in the healing of venous ulcer.

Endovenous laser treatment (ELT) is a minimally invasive ultrasound-guided technique used for treating varicose veins using laser energy commonly performed by a phlebologist, interventional radiologist or vascular surgeon.

The NICE guidelines recommends that everyone with a venous leg ulcer, even if healed, should be referred to a "vascular service" for venous duplex ultrasound and assessment for endovenous surgery.

There are three kinds of endovenous thermal ablation treatment possible: laser, radiofrequency, and steam. The Australian Medical Services Advisory Committee (MSAC) in 2008 determined that endovenous laser treatment/ablation (ELA) for varicose veins "appears to be more effective in the short term, and at least as effective overall, as the comparative procedure of junction ligation and vein stripping for the treatment of varicose veins."Medical Services Advisory Committee, ELA for varicose veins. MSAC application 1113, Dept of Health and Ageing, Commonwealth of Australia, 2008.

Active treatments can be divided into surgical and non-surgical treatments. Newer methods including endovenous laser treatment, radiofrequency ablation and foam sclerotherapy appear to work as well as surgery for varices of the greater saphenous vein.

Since pulmonary hypertension is the leading cause of death, its early diagnosis by routine echocardiography and the rapid initiation of treatment with endothelin-1 antagonists (bosentan), phosphodiesterase 5 inhibitors (sildenafil) or endovenous prostacyclins (epoprostenol) manage to considerably improve morbidity and mortality.

He has developed the No-Knife Endovenous Laser Ablation. His procedure does not use the plastic sheath that was used before which leaves scars. The process uses a laser that is focused through a skinny needle to seal problems in veins.

The current 'best' practice in the UK is to treat the underlying venous reflux once an ulcer has healed. It is questionable as to whether endovenous treatment should be offered before ulcer healing, as current evidence would not support this approach as standard care. EVRA (Early Venous Reflux Ablation) ulcer trial – A UK NIHR HTA funded randomised clinical trial to compare early versus delayed endovenous treatment of superficial venous reflux in patients with chronic venous ulceration opened for recruitment in October 2013. The study hopes to show an increase in healing rates from 60% to 75% at 24 weeks.

Endovenous thermal ablation (EVTA) by radiofrequency or laser is a safe and effective treatment of refluxing great saphenous veins (GSVs) and has replaced traditional high ligation and stripping in official recommendations of various leading Vascular Societies in the United States and the United Kingdom.

Editors Murad Alam, Sirunya Silapunt. Second Edition Saunders Elsevier Inc. 2011 Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open surgery. The biggest risk, however, seems to occur with sclerotherapy, especially in terms of systemic risk of DVT, pulmonary embolism, and stroke.

Many discussions exist about this vein, some of them confusing to a non-expert reader. Insufficiency in the Giacomini vein can present in isolation but is mostly seen together with a GSV insufficiency. It has been shown to be effectively treated either with endovenous laser ablation or by ultrasound guided sclerotherapy.

The benefits of Image-guided surgery include greater control of the surgical procedure, real-time feedback on the effect of the intervention, reduced tissue trauma and disruption in gaining access to the anatomical structure. Image-guided surgery allows for: reduced post-operative neural deficits and adverse events associated with endovenous laser ablative procedures, and more effective removal of brain tumors that were once considered inoperable due to their size or location.

Complications of endovenous laser treatment can be categorized as minor, or serious. Minor complications include bruising (51%), hematoma (2.3%), temporary numbness (3.8%), phlebitis (7.4%), induration (46.7%), and a sensation of tightness (24.8%). More serious complications include skin burns (0.5%), deep venous thrombosis (0.4%), pulmonary embolism (0.1%), and nerve injury (0.8%). These rates of complications are derived from the Australian MSAC review of all available literature on the procedure.

It is sometimes called chronic peripheral venous insufficiency and should not be confused with post- thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis. Most cases of CVI can be improved with treatments to the superficial venous system or stenting the deep system. Varicose veins for example can now be treated by local anesthetic endovenous surgery. Rates of CVI are higher in women than in men.

Venous insufficiency is the most common disorder of the venous system, and is usually manifested as spider veins or varicose veins. Several varieties of treatments are used, depending on the patient's particular type and pattern of veins and on the physician's preferences. Treatment can include Endovenous Thermal Ablation using radiofrequency or laser energy, vein stripping, ambulatory phlebectomy, foam sclerotherapy, lasers, or compression. Postphlebitic syndrome is venous insufficiency that develops following deep vein thrombosis.

ELA is performed as an outpatient procedure and does not require an operating theatre, nor does the patient need a general anaesthetic. Doctors use high-frequency ultrasound during the procedure to visualize the anatomical relationships between the saphenous structures. Some practitioners also perform phlebectomy or ultrasound guided sclerotherapy at the time of endovenous treatment. Follow-up treatment to smaller branch varicose veins is often needed in the weeks or months after the initial procedure.

Cyclophosphamide are useful in interstitial lung disease and in the eventual serious renal involvement. In cases of myositis or thrombocytopenias resistant to corticosteroids, intravenous immunoglobulins may be useful. For Raynaud, general measures (such as tobacco cessation, protection against the cold), calcium antagonists, endovenous prostaglandins or endothelin-2 antagonists may be useful. In patients with gastroesophageal reflux, proton pump inhibitors and H2 receptor antagonists can be used, following protocol for the usual treatment of these scleroderma problems.

It also found in its assessment of available literature, that "occurrence rates of more severe complications such as DVT, nerve injury, and paraesthesia, post-operative infections, and haematomas, appears to be greater after ligation and stripping than after EVLT". Complications for ELA include minor skin burns (0.4%) and temporary paresthesia (2.1%). The longest study of endovenous laser ablation is 39 months. Two prospective randomized trials found speedier recovery and fewer complications after radiofrequency ablation (ERA) compared to open surgery.

Myers wrote that open surgery for small saphenous vein reflux is obsolete. Myers said these veins should be treated with endovenous techniques, citing high recurrence rates after surgical management, and risk of nerve damage up to 15%. By comparison ERA has been shown to control 80% of cases of small saphenous vein reflux at 4 years, said Myers. Complications for ERA include burns, paraesthesia, clinical phlebitis and slightly higher rates of deep vein thrombosis (0.57%) and pulmonary embolism (0.17%).

Arterial and venous disease treatment by angiography, stenting, and non- operative varicose vein treatment sclerotherapy, endovenous laser treatment are rapidly replacing major surgery in many first world countries. These newer procedures provide reasonable outcomes that are comparable to surgery with the advantage of short hospital stay (day or overnight for most cases) with lower morbidity and mortality rates. Historically performed by interventional radiologists, vascular surgeons have become increasingly proficient with endovascular methods. The durability of endovascular arterial procedures is generally good, especially when viewed in the context of their common clinical usage i.e.

Venous ulcers are costly to treat, and there is a significant chance that they will recur after healing; one study found that up to 48% of venous ulcers had recurred by the fifth year after healing. However treatment with local anaesthetic endovenous techniques suggests a reduction of this high recurrence rate is possible. Without proper care, the ulcer may get infected leading to cellulitis or gangrene and eventually may need amputation of the part of limb in future. Some topical drugs used to treat venous ulcer may cause venous eczema.

In a letter to the International Journal of Cardiology, Tsung O. Cheng called out his own field as prone to overuse of contrived acronyms, calling it a "persistent problem". He was spurred to write the letter after he reviewed nine articles about a study named "ZAHARA" without finding any explanation of what the acronym meant. Other clinical trials that have been noted in publications for their acronyms include: TORPEDO (Thrombus Obliteration by Rapid Percutaneous Endovenous Intervention (PEVI) in Deep Venous Occlusion) and BATMAN (Bisphosphonate and Anastrozole Trial – Bone Maintenance Algorithm Assessment).

Endovenous laser treatment treats varicose veins using an optical fiber that is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum, shines into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn. Some minor complications can occur, including thrombophlebitis, pain, hematoma, edema and infection, which can lead to cellulitis. EVLT has the same meaning as ELT, but it is a trademark name owned by Diomed and used as the name for their 910 nm laser treatment unit for ELT.

From 1993 to 1995, while still studying the fine form of vascular surgery, Campbell worked in the less advantaged areas of Nambour and Cairns to help increase the quality of available medical needs. During this time, Lynne gave birth to his fourth child, daughter Madeleine in 1993. His dedication to his work saw him posted to Melbourne in 1998 where he worked for the Royal Melbourne Hospital, the Alfred Hospital and the Epworth. In 2009 he became one of the first Vascular surgeons in Australia to use less invasive surgical procedures such as (UGS) ultrasound guided sclerotherapy and endovenous laser ablation of varicose veins.

The latter are connecting veins that transport blood from the superficial veins to the deep veins. Branch varicose veins are then usually treated with other minimally invasive procedures, such as ambulatory phlebectomy, sclerotherapy, or foam sclerotherapy. Currently, the VNUS ClosureRFS stylet is the only device specifically cleared by FDA for endovenous ablation of perforator veins.Endovenous ablation of perforator veins The possibility of skin burn during the procedure is very small, because the large volumes (500 cc) of dilute Lidocaine (0.1%) tumescent anesthesia injected along the entire vein prior to the application of radiofrequency provide a heat sink that absorbs the heat created by the device.

A 2005 report from one practice, summarising results of 1,000 limbs treated over a 5-year period with EVLT showed that 98% of the treated vessels at up to 60 months follow-up remained closed, with complications and side effects such as temporary parasthesia and DVTs below 0.5%. The Australian Medical Services Advisory Committee (MSAC) in 2008 has determined that endovenous laser treatment for varicose veins "appears to be more effective in the short term, and at least as effective overall, as the comparative procedure of junction ligation and vein stripping for the treatment of varicose veins." It also found in its assessment of available literature, that "occurrence rates of more severe complications such as DVT, nerve injury and paresthesia, post-operative infections and hematomas, appears to be greater after ligation and stripping than after EVLT". A study of 516 treated veins over 69 months by Elmore and Lackey reported a success rate of 98.1%.
