Successful Treatment of Chronic Venous Ulcers With a 1,320-nm Endovenous Laser Combined With Other Minimally Invasive Venous Procedures

Comparative analysis of endovenous laser ablation versus ultrasound-guided foam sclerotherapy for the treatment of venous leg ulcers

BACKGROUND

Endovenous thermal and non-thermal therapeutic approaches have become standard of care for the treatment of venous insufficiency. However, comparative studies on its use in the population of venous leg ulcer patients are scarce.

METHODS

The present study aimed at a comparison of the efficacy of endovenous laser ablation (EVLA) and ultrasound-guided foam sclerotherapy (UGFS) for the treatment of venous leg ulcers (VUs). We retrospectively analyzed patient records of 68 patients with active VUs (C6 of the CEAP-classification), who underwent EVLA (n=33) or UGFS (n=35) between January 2001 and January 2021.

RESULTS

In 68 patients, 97 venous segments (GSV: 43, SSV: 17:, NSV: 37) were treated. Ulcer surface area at initial presentation did not differ significantly between both treatment groups (EVLA: 7.7±10.7 vs. UGFS: 8.5±16.3 cm² ; p=0.73). No significant difference regarding patient characteristics was found, with the exception of age, as patients receiving UGFS treatment were significantly older (EVLA: 61±17 vs. UGFS: 70±14 years; p=0.018). The rate of ulcer resolution was not significantly different between EVLA and UGFS groups (97.0% vs. 85.7%; p=0.20). Also, the mean time to complete ulcer healing after endovenous intervention was comparable (EVLA: 59±37 vs. UGFS: 63±41 days; p=0.68). However, the relapse rate was significantly higher for UGFS than for EVLA treated patients (31.4% vs. 3.0%; p=0.002).

CONCLUSION

Rates of ulcer resolution and ulcer healing time after endovenous intervention were comparable between both treatment modalities. However, a significantly higher relapse rate was observed in UGFS treated patients.

Challenges of treating mixed arterial-venous disease of lower extremities

INTRODUCTION

Mixed arterial-venous lower extremity disease (AVLED) poses a unique challenge for clinicians. This review will outline the impact mixed AVLED has on patients and the healthcare system, by reviewing its epidemiology, diagnosis, current treatment, and the challenges encountered implementing therapies.

EVIDENCE ACQUISITION

An extensive search of current literature from online sources, journals and book chapters identified the current challenges facing the treatment of mixed arterial venous ulcers of the lower extremities and potential solutions to these challenges.

EVIDENCE SYNTHESIS

The challenges that are identified in the search are the time to heal AVLED, patient education and motivation, early detection of AVLED, wound care center development, treatment consensus from multidisciplinary team members, and cost of treatment.

CONCLUSIONS

AVLED ulcers are a challenging problem, but over time we have continued and will continue to improve patient care and tackle these difficult challenges as we have throughout the last century. A diagnostic algorithm to address how we approach these patients in terms of conservative care with wound care and compression and treat arterial and venous insufficiency is crucial. In looking to the future, continued standardization of wound care centers will overcome the social and financial challenges faced by patients and continued clinical research will improve targeted therapies and treatment challenges faced by physicians.

Combined neodymium-doped yttrium aluminum garnet laser and sclerotherapy in Gorham-Stout syndrome

Bone involvement is relatively rare in vascular malformations. Gorham-Stout disease, also referred to as vanishing bone disease, is characterized by osteoclast activation and osteolysis caused by proliferating lymphatic endothelial cells. We present the case of a 12-year-old boy who had Gorham-Stout disease at the age of 8 years. The clinical course was complicated by pathological fractures and localized intravascular consumption coagulopathy. Sclerotherapy and embolization therapy led to normalization of the coagulation parameters and significant improvement of the clinical findings. We speculate that this effect may be attributable to the elimination of lymphatic endothelial cells.
