This report distills evidence on surgical techniques for deep venous incompetence to inform health ministry decisions on reimbursement policy in Alberta. The Alberta Heritage Foundation for Medical Research, through its Health Technology Assessment Unit, commissioned this report to provide a comprehensive overview of current surgical methods for deep venous incompetence. The document details the pathogenesis of chronic venous insufficiency, explaining the roles of the superficial and deep venous systems, the calf muscle pump, and venous valves in maintaining blood flow. It differentiates between primary CVI, caused by venous wall and valve abnormalities without prior thrombosis, and secondary CVI, often resulting from deep vein thrombosis. The report also outlines how ligating superficial and perforating veins can improve limb hemodynamics by reducing high pressure transmission to the skin and subcutaneous tissues in patients with primary CVI affecting multiple venous systems.

This report serves as a technical assessment intended for policy-makers within the Alberta Ministry of Health, focusing on the evidence base for surgical treatments of deep venous incompetence. Its primary function is to inform decisions regarding the reimbursement of these surgical procedures. The document's structure and content suggest a clinical and evidence-based approach, aiming to provide a clear distillation of current knowledge for a specific administrative purpose.
