Patients with vascular spiders and angiomas, especially on exposed sites, demonstrate considerable psychological morbidity and therefore request treatment. Traditionally, electrosurgical modalities have been used to treat such lesions, but more recently lasers have been introduced. This open study assesses the efficacy of these two treatment modalities, scoring patients' preference and psychological morbidity before and after treatment. All patients had two vascular spiders or angiomas. One lesion was randomized for treatment with the hyfrecator, whilst the other lesion was treated with the potassium titanyl phosphate (KTP) vascular laser. The end-point of the study was either clearance of lesions or a maximum of three treatments at 2-month intervals. In this first comparative study, we demonstrate that both therapeutic modalities were effective in treating these lesions and in significantly reducing the post-treatment psychological morbidity score. However, on average, only one treatment with the KTP laser was required to achieve clearance compared with two treatments with the hyfrecator. This would result in less clinic visits. In addition, patients favoured the KTP laser because of the lack of side-effects. Both the KTP vascular laser and the hyfrecator were able to clear vascular spiders and angiomas, but the KTP laser was superior as fewer treatment episodes were required and patients preferred this treatment modality because of the lack of side-effects.
