A study of duplex ultrasound examination in peripheral vascular malformations

Abstract

Vascular malformations belong to wide spectrum of disease involving all vascular segments- arteries, veins as well as lymphatics. Being Ultrasound as the primary diagnostic modality, all peripheral vascular malformation diagnosis can be made by clinical examination and duplex ultrasound examination.A study of 50 patients was carried over a period of 1 year from 1 May 2021 to 1 May 2022 on the patient who came with complain of slow growing, superficial swelling which is painless in nature. The machine used is Affinity Philips 70 G.With help of duplex ultrasound, various types of vascular malformations were diagnosed with incidence such as Slow Flow Venous malformation (60%- 30 patients), High flow Arterio-venous malformations (16%- 8 patients), Capillary malformations (12%- 6 patients) and Lymphatic malformations (12%- 6 patients).Vascular malformations have been classified into venous, arterial, capillary, combined and lymphatic malformations types. Besides age presentations, detailed history and clinical examination, ultra-sound imaging plays an important role in correct diagnosis and classification of vascular malformations. It assesses exact flow dynamics in order to differentiate between Slow flow v/s High flow vascular malformations. MRI is most valuable diagnostic tool for comprehensive assessment of vascular malformationsUltrasound are first imaging modality in peripheral vascular malformations. It has plays crucial role in proper treatment planning of the lesion as it describes the extent, type, flow pattern within the lesion.
