Background: Lobular capillary hemangioma (LCH) is an acquired benign vascular tumor that causes suffering to the child and whose treatment is often associated with recurrences.
Objective: To compare the efficacy and recurrence rate of laser photocoagulation methods with Nd:YAG laser 1064 nm for lobular capillary hemangioma of the skin in children.
Methods: A retrospective analysis of the results of LCH in skin treatment in children was conducted in the Children's Republican Clinical Hospital, Kazan, Russia between 2007 and 2024. Two Nd:YAG 1064 nm laser coagulation methods were compared. The first method involved photocoagulation of the exophytic mass using 30 ms pulses with an energy density of 120–130 J/cm². The second method included an additional step of non-contact exposure of the feeding vessels following exophytic mass removal, according to a patented technique (RU patent no. 2814754).
Results: During the specified period, 255 LCH photodestruction procedures were performed: 144 using Method 1 and 111 using Method 2. The average LCH diameter was 5.5±0.9 mm. The mean patient age was 41.2±13.6 months (range: 0 to 111 months). Over a 6 month follow-up period, 9 recurrences were recorded in Group 1, with there no recurrences in Group 2.
Conclusions: A two-stage method of LCH laser photocoagulation, performed according to a patented technique and involving photodestruction of the exophytic component followed by coagulation of the feeding vessels at its base, ensures radical removal of all vascular structures, including basal vessels. The results of the research demonstrate a statistically significant advantage of this method compared to single-stage photocoagulation.
