Abstract
Objective
For this retrospective study, we analyzed the sub-ulcer foam sclerotherapy technique in patients with venous leg ulcer (VLU).
Methods
This study included 134 patients treated with sub-ulcer foam sclerotherapy at the Oulu University Hospital vascular outpatient clinic from January 2012 to December 2021. All included patients received sub-ulcer foam sclerotherapy as part of the treatment strategy for superficial venous insufficiency. Compression therapy and local wound care were organized for VLU treatment. A follow-up visit was scheduled for one month after the sub-ulcer foam sclerotherapy. Change in ulcer size, local (skin necrosis, infection) or systemic (deep vein thrombosis, pulmonary embolism) complications, and time to ulcer healing were monitored. The occurrence of major limb-related complications (amputation, surgical revision) was monitored for one year postoperatively.
Results
One month after sub-ulcer treatment, ulcers were smaller or completely healed in 108 (81%) patients. Ulcer healing was completed in 123 (92%) patients at one year and 131 (98%) patients at two years. Complications were recorded in four (3%) patients, three (2%) who were diagnosed with erysipelas requiring antibiotic treatment and one (1%) patient diagnosed with local dermatitis. During the one-year follow-up, no major limb-related complications (surgical revisions or amputations) arose.
Conclusions
Sub-ulcer foam sclerotherapy may be a feasible addition to superficial vein reflux elimination in patients with VLU and a low risk for complications.
