History and Evolution of Vascular Surgery in Sri Lanka: The Journey and Ongoing Challenge

Gunawansa N, Cassim R, Wijeyaratne M · European Journal of Vascular and Endovascular Surgery (Editorial) · 2026

This editorial traces the development of vascular surgery in Sri Lanka from its early focus on amputation to modern arterial reconstruction, limb salvage, endovascular therapy, and specialist training. It highlights the pioneers, institutions, clinical advances, and resource constraints that shaped the specialty, while examining the close relationship between vascular surgery and renal transplantation and the challenges that remain for expanding endovascular care.
