Foam sclerotherapy for lower-limb varicose veins: impact on saphenous vein diameter

Bilateral foam polidocanol sclerotherapy of great saphenous veins and their tributaries in synchronous procedure

Background

Chronic venous insufficiency is a highly prevalent disease. Advanced cases have high morbidity.

Objectives

To evaluate the risks and benefits of foam sclerotherapy in patients who underwent bilateral treatment of the great saphenous veins in a single procedure, in selected cases of advanced venous insufficiency.

Methods

We retrospectively reviewed 55 patients (110 limbs) with bilateral incompetence of the great saphenous veins who had undergone foam sclerotherapy treatment bilaterally, using a maximum dose of 20 ml of foam per patient and inelastic compression.

Results

In 81 (73.6%) of the 110 saphenous veins analyzed, occlusion was obtained in the first session. After a second session this figure rose to 106 (96.3%) and all 110 (100%) veins were occluded after three sessions. Bilateral occlusion of the great saphenous veins was achieved in 27 patients (50%) in one session, in 34 (62%) patients in two sessions, and in 55 (100%) patients in three sessions. At 42 days after sclerotherapy, there was complete ulcer healing in seven (63%) of the 11 patients with ulcers and partial healing in 3 (27%) of these patients. One patient (1.8%) had self-limited lipothymia and visual scotomas, 3 patients (5.45%) had skin spots, and 19 patients (34.5%) developed retained intravascular coagulum.

Conclusions

Bilateral foam sclerotherapy in a synchronous procedure is an option to be considered for treatment of varicose veins of the lower limbs.

Efficacy and safety of polidocanol in the treatment of varicose veins of lower extremities: A protocol for systematic review and meta-analysis

BACKGROUND

The varicose veins of the lower extremities showed earthworm-like dilatation and venous protrusion of the lower extremities. Polidocanol foam sclerotherapy, as a minimally invasive treatment with rapid recovery, less trauma and not easy to relapse, has achieved good results in clinical, but it is lack of evidence-based medicine. The purpose of this study is to evaluate the efficacy and safety of polidocanol in the treatment of varicose veins of the lower extremities by meta-analysis.

METHOD

Chinese National Knowledge Infrastructure, Wanfang Database, Chinese Scientifific Journals Database, China Biology Medicine disc, PubMed, EMBASE database, Web of Science, and Cochrane Library will be used as search sources to conduct for randomized controlled trials of polidocanol in the treatment of varicose veins of lower extremities. The search time is set from the establishment of the database in December 2020 in this study. Two researchers independently extract, delete files, extract data and evaluate the quality. Revman software version 5.3 will be used for statistical analysis of data.

RESULT

In this study, the efficacy and safety of polidocanol in the treatment of varicose veins of the lower extremities will be evaluated in terms of total effective rate, incidence of complications and recurrence rate.

CONCLUSION

This study will provide reliable evidence-based evidence for the clinical application of polidocanol in the treatment of varicose veins of lower extremities.

A microneedling device for the treatment of spider vein: A case report

Spider vein is mostly seen in patients with liver disease, although the underlying problem is sometimes unknown. If spider vein appears on the face, it can affect the self-esteem and self-image of patients. Particularly, females are more vulnerable to these complications. Spider nevi are mostly left untreated since they are considered a cosmetic matter; in case of treatment, the procedure is costly with limited satisfaction. Therefore, this study reports the successful treatment of a spider vein case using a microneedling procedure.

Foam-in-vein: A review of rheological properties and characterization methods for optimization of sclerosing foams

Varicose veins are chronic venous defects that affect >20% of the population in developed countries. Among potential treatments, sclerotherapy is one of the most commonly used. It involves endovenous injection of a surfactant solution (or foam) in varicose veins, inducing damage to the endothelial layer and subsequent vessel sclerosis. Treatments have proven to be effective in the short-term, however recurrence is reported at rates of up to 64% 5-year post-treatment. Thus, once diagnosed with varicosities there is a high probability of a permanently reduced quality of life. Recently, foam sclerotherapy has become increasingly popular over its liquid counterpart, since foams can treat larger and longer varicosities more effectively, they can be imaged using ultrasound, and require lower amounts of sclerosing agent. In order to minimize recurrence rates however, an investigation of current treatment methods should lead to more effective and long-lasting effects. The literature is populated with studies aimed at characterizing the fundamental physics of aqueous foams; nevertheless, there is a significant need for appropriate product development platforms. Despite successfully capturing the microstructural evolution of aqueous foams, the complexity of current models renders them inadequate for pharmaceutical development. This review article will focus on the physics of foams and the attempts at optimizing them for sclerotherapy. This takes the form of a discussion of the most recent numerical and experimental models, as well as an overview of clinically relevant parameters. This holistic approach could contribute to better foam characterization methods that patients may eventually derive long term benefit from.

Short Term Outcome of Adjunct Foam Sclerotherapy for Varicose Veins in Patients Subjected to RFA at Dhulikhel Hospital, Nepal

Background

Varicose veins are dilated, tortuous, superficial veins usually seen on lower limbs. Various surgical modalities are available for varicose veins including open surgery (Trendelenburg operation), Endovenous Laser Ablation (EVLA), Radiofrequency Ablation (RFA) and Sclerotherapy. The aim of this study is to look for the outcome of adjunct sclerotherapy for varicose veins done as an adjunct with Radio Frequency Ablation.

Objective

To know the possible outcome regarding benefits and complications of adjunct sclerotherapy with Radio Frequency Ablation.

Methodology

We combined Radio Frequency Ablation of varicose veins with necessary phlebectomy and perforator ligation and performed adjunct sclerotherapy for residual significant varicosities with polidocanol (2%) mixed with 2 ml NS and 2 cc of air (Tessari method) to patients undergoing varicose vein surgery in between 2016 and 2017. Records on complications were enquired immediately following surgery and on 1^st follow up done within 3-5 days of the procedure.

Results

Among 256 limbs subjected to varicose veins surgery 51 limbs were given adjunct sclerotherapy. Among them, five limbs had perivenous spillage with some localized swelling while there was allergic reaction in one patient as immediate postprocedural complication. Nine limbs had painful thrombosed veins during early follow-up.

Conclusions

Adjunct sclerotherapy showed complication rate of roughly one tenth and one fifth of the treated cases in immediate and early postoperative follow-up.
