Treatment of severe chronic venous insufficiency using the subfascial endoscopic perforator vein procedure

Clinical Tests Combined with Color Doppler Versus Color Doppler Alone in Identifying Incompetent Perforator Veins of the Lower Limb: A Prospective Analytical Study

Background The color Doppler, a better investigation to identify the perforators objectively has replaced the clinical examination for the same. However, this has led to a significant number of negative explorations and cosmetic disfigurement. Objective To compare the efficacy of the clinical tests combined with the color Doppler versus color Doppler alone to identify the perforator incompetence during the surgery for primary varicose veins of the lower limb. Methods This was a prospective analytical study, including 61 lower limb varicose vein patients who belonged to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) class four-six, planned for the surgical treatment for perforator incompetence, excluding those requiring additional vascular or nonvascular procedure, recurrent varicose veins and those who had injection sclerotherapy prior to the surgery. The clinical tests, including Trendelenburg's test, multiple tourniquet tests and, the Fegan's tests were performed and incompetent perforators were marked on a template as 'C' to indicate the clinically positive perforator incompetence. The patients were then examined with the color Doppler ultrasound and the pathological incompetent perforators were marked as 'D'. The surgical management of the perforator incompetence was done by stab ligation. The incision was made in the color Doppler 'D' marked sites as it has been the standard protocol. The number of incompetent perforators identified during the surgical exploration were categorized as 'D' positive or 'C' and 'D' positive and were recorded in the specified proforma. Results It was found that the mean number of the perforator incompetence identified by the color Doppler alone was 8.2 whereas during the surgery, only a mean of six perforators was identified, leading to 20 unnecessary explorations per 10 patients (8.2 vs. 6; mean difference 2.229; P <0.001). The mean number of the perforator incompetence identified by the color Doppler combined with the clinical tests was 4.5 and during the surgery, a mean of four perforators was identified (4.5 vs. 4; mean difference 0.377; P <0.001). The color Doppler combined with the clinical examination lead to only four unnecessary explorations per 10 patients. Conclusion A combination of both the clinical tests and the color Doppler ultrasound has a higher accuracy in detecting perforator incompetence and can reduce the number of negative explorations by the rate of 16 unnecessary explorations per 10 patients.

Impact of lower extremity venous ulcers due to chronic venous insufficiency on quality of life

Lower extremity venous ulcers comprise a complex medical and social issue. The conservative and/or surgical management of venous ulcers is often inadequate. In addition, the psychosocial aspect of the disease is often overlooked and most often undertreated. Common symptoms such as pain, low self-esteem and patient isolation are usually not recognized and therefore not adequately managed.This mini-review summarizes the current data on the management of lower extremity venous ulcers and their impact on the quality of life of these patients.

Subfascial endoscopic perforator vein surgery (SEPS) modified technique: subaponeurotic approach without balloon

Subfascial Endoscopic Perforator Vein Surgery (SEPS) is one of the best procedures and a minimally invasive option for treating chronic venous insufficiency. We explain our experience with SEPS, which has been turned into a subaponeurotic approach without balloon, and assess the possible advantages of this technique. The subaponeurotic space was entered using the Visiport Plus (Autusuture, Tyco Healthcare) video-assisted technique, which shows how the trocar enters through the subcutaneous tissue and superficial aponeurosis of the leg. A blunt retractor was inserted which, together with CO2 insufflation (20 mm Hg), enabled the veins to be dissected. Ligation was performed using tripolar sealing. In no case was a balloon used. There were no incidents such as haemorrhage or subcutaneous emphysema during the procedure. The patients (n = 206) remained in the hospital for less than 24 hours and suffered no post-surgical complications. Active ulcers were cured, with no relapses, in 100% of cases. This is a very effective method for treating advanced chronic insufficiency because it prevents local damage and the rate of post-surgical complications is low. Technically it has more advantages because the fact that it does not use a balloon means that it exerts less pressure on the tissues.

Use of ultrasonic scalpel in subfascial endoscopic perforator vein surgery: a novel approach

BACKGROUND

The aim of this study was to determine the feasibility of using the ultrasonic scalpel in subfascial endoscopic perforator vein surgery (SEPS) and study the results of ulcer healing and reversal of skin changes.

MATERIALS AND METHODS

From January 2003 to November 2005, we performed 47 SEPS in 42 patients under spinal anesthesia, using the two-port technique. All patients had chronic venous insufficiency ranging from class IV to VI.

RESULTS

Duration of surgery for SEPS averaged 30 minutes, with no postoperative mortality. One patient developed a wound infection at the port site, which was managed conservatively. None of the procedures required a conversion to open surgery. We have had no recurrence of venous ulcer, so far. Barring 1 patient, all patients returned to normal routine within 5 days of surgery. In more then 90% of patients, ulcer healing was achieved within 8 weeks of surgery.

CONCLUSION

Our study clearly shows that the ultrasonic scalpel is a very safe, reliable tool in SEPS, as there was very low morbidity regarding wound complications and other per- or postoperative complications, which can be there when one uses the metallic clips or electrocautery for SEPS.

The treatment of varicose veins

INTRODUCTION

Over the past few years, there has been a move to less invasive endoluminal methods in the treatment of lower limb varicose veins combined with a renewed interest in sclerotherapy, with the recent addition of foam sclerotherapy. The development of these new techniques has led many to question some of the more conventional teaching on the treatment of varicose veins. This review examines these new treatments for lower limb varicose veins and the current evidence for their use.

MATERIALS AND METHODS

An extensive search of available electronic and paper-based databases was performed to identify studies relevant to the treatment of varicose veins with particular emphasis on those published within the last 10 years. These were analysed by both reviewers independently.

RESULTS

There is no single method of treatment appropriate for all cases. Conventional surgery is safe and effective and is still widely practised. Whilst the new treatments may be popular with both surgeons and patients, it is important that they are carefully evaluated not only for their clinical benefits and complications when compared to existing treatments but also for their cost prior to their wider acceptance into clinical practice.
