Clinical observations in mesh suture treatment for infants of Kasabach-Merritt phenomenon

AimThis study aims to evaluate the efficacy and adverse effects of the mesh suture treatment for infants of Kasabach-Merritt phenomenon and to report our treatment experience. MethodsOf the three patients, two of the cases occurred in the scalp and one occurred in the back of the chest, with platelet counts < 40 x 10(9)/L before the treatment, reduced fibrinogen levels and increased D-dimer levels. All the three patients underwent the mesh suture treatment of the tumour area. Post-treatment observations were made regarding the surface colour and texture of the tumours, periodic routine blood examination results, fibrinogen and D-dimer levels. ResultsAfter treatment, the degree of swelling on the tumour surface was reduced, surface tension was decreased, the tumour colour turned pale red from dark red and the skin gradually returned to normal. Two days after treatment, the platelet counts increased to 70 x 10(9)/L or higher; the platelet count reached a normal level after 1 week in two cases. The fibrinogen level increased in varying degrees after treatment, whereas the D-dimer level was reduced. One case showed a small amount of exudate at the suture area, 1 month after the treatment; improvements were observed 3 days after changing the local dressing. All the patients were followed up for 6 months to 1 year, during which the patients showed complete regression of the lesion and relapse, normal platelet counts and normal fibrinogen and D-dimer levels. ConclusionsWe recommend the mesh suture treatment as the first treatment of choice for paediatric Kasabach-Merritt phenomenon.
