Study summary

The aim of the BEST study is to examine the feasibility of assessing patient and clinician reported outcome of a single electrosclerotherapy treatment of vascular malformations.

  • Sclerotherapy = injection of Bleomycin into vascular birthmarks to seal off abnormal vascular channels
  • Electroporation = application of an electric field to vessels treated with a handheld needle electrode
  • Electrosclerotherapy = a combination of Bleomycin sclerotherapy and electroporation

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Change in Quality of life questionnaire scores between baseline and 6-8 weeks of treatment

    Patient reported quality of life after a single electrosclerotherapy treatment of vascular malformations - change in scores measured using Birthmark Quality of Life questionnaire (8 items measured on 5 point scale)

    Time frame: 8 weeks

  2. Clinician assessment tool of treatment response

    Clinician assessment of treatment response following electrosclerotherapy treatment using clinical assessment tool - change in scores measured

    Time frame: 8 weeks

Secondary outcomes

  1. To collect documented side effects following electrosclerotherapy treatment.

    To collect documented side effects following electrosclerotherapy treatment using diary

    Time frame: 2 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 10, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
