[Verapamil in conjunction with pressure therapy in the treatment of pathologic scar due burn injury].

Background: Keloids and hypertrophic scars are dermal fibro-proliferative disorders unique to humans. Their treatment is a true challenge with multiple options, but not all the time with good results. Unfortunately this problem is not uncommon in patients with history of burn injury. The aim of this article is to evaluate the use of verapamil and pressure garments in patients with hypertrophic or keloid scar caused by burn injury.

Methods: We included patients with a hypertrophic or keloid scar caused by burn injury candidate to treatment with pressure garment. The pathologic scars were evaluated by serial photographic records, Vancouver and Posas scales. The scales of Vancouver and Posas were compared with t Student.

Results: We included 13 scars in 11 patients. Four scars were located in the legs, 4 in the arms, 4 in the face-neck and 1 in the abdomen. The dose of verapamil was calculated .03mg per kg. Injections were scheduled every 7 to 10 days until complete 6 sessions. Taking in count Posas scale, patients referred improvement in pigmentation (.01), thickness (.005), pliability (.01) and surface area (.004). In the Vancouver scale the observers mentioned improvement in elevation (.008), pigmentation (.014), vascularity (.022), flexibility (.014) and pruritus (.003). No adverse effects were found in verapamil injection.

Conclusions: Verapamil was useful in conjunction with pressure garment to improve the condition of the keloid and hypertrophic scar caused by burn.
