Low-flow vascular malformations of the hand and forearm: a multidisciplinary experience in a tertiary paediatric centre.

BACKGROUND

Vascular malformations (VMs) involving the hand and forearm in children provide management challenges due to complex anatomy, indispensable functionality and developmental implications.

METHODS

The institution's Vascular Registry was searched for patients with hand and arm VMs, supplemented by chart review of included patients.

RESULTS

Twenty-one patients were identified, 52% male, with mean presenting age 5.2 years. Venous malformations predominated (71%), followed by lymphatic-venous (19%), lymphatic (5%) and glomuvenous (5%). Symptoms included pain (76%), swelling (71%), cosmetic concerns (81%), functional compromise (29%) and stiffness (5%). Imaging modality was ultrasound (100%), and magnetic resonance imaging (71%). Treatment included compression (62%), sclerotherapy (62%) and surgery (24%). Post-sclerotherapy ultrasounds showed complete sclerosis (25%), near complete sclerosis (58%) and partial sclerosis (17%). Post-surgery, patients reported improved cosmesis (80%), size (100%), pain (60%) and function (40%). Complications occurred in 24%, including bleeding, digital ischaemia and thrombosis. Mean follow-up was 3.4 years.

CONCLUSION

Children with low-flow VMs of the hand and forearm experience significant symptoms and functional limitations. A multidisciplinary approach to management ensures optimal outcomes.
