Results of intralesional injection of n-butyl cyanoacrylate (NBCA) and fibrin glue in hemangioma and low flow vascular malformations

Background and Objectives: Complete surgical excision of vascular anomalies is technically difficult and seldom possible, prompting interest in other treatment options, especially sclerotherapy. We decided to study the results of intralesional injection of n-butyl cyanoacrylate (NBCA) and autologous fibrin glue (FG) in hemangiomata and vascular malformations (VMs). Materials and Methods: This prospective study was conducted in fifty consecutive patients of hemangioma and VMs. Frequency of injections was decided according to size and injections were given at the interval of 4 days to complete the treatment in 30 days. Postinjection reduction in size of the lesion was assessed. Lesions which did not disappear or those having complications were taken for surgery and amount of blood loss during excision was estimated. Results: In NBCA group, the mean reduction in size of hemangioma and low flow VM was 63.85%—73.3%; in FG Group, it was 51.9%—53.80%, respectively. In FG group, the mean blood loss was 37.5 ml for a mean size of 3.6 cm2 hemangioma and 79.55 ml for low flow VM with a mean size of lesion 2.23 cm2. In NBCA group, the mean blood loss was 37.5 ml for mean size of 4.4 cm2 hemangioma and 37.5 ml with a mean size of 3.55 cm2 low flow VM. Conclusion: Repeated intralesional injections of NBCA and FG in hemangioma and VMs are associated with significant reduction in size and blood loss during excision. Small vascular lesions (
