Best practices in diagnosis and treatment of chronic iliac vein obstruction
Abstract
Iliac vein obstruction occurs in 20-30% of the general population. In patients with severe chronic venous insufficiency, this prevalence can be even higher, reaching 50-90% when the obstruction is investigated using intravascular ultrasound. Less invasive methods, such as venous Duplex Scanning, and even invasive ones such as venography may fail to diagnose the condition. Endovascular treatment of these obstructions is effective, safe, and associated with excellent clinical outcomes and stent patency rates, provided that fundamental anatomical and technical principles are considered and applied.
Resumo: A obstrução venosa ilíaca ocorre em 20% a 30% da população. Nos portadores de insuficiência venosa crônica grave, essa prevalência é ainda maior, podendo chegar a 50% a 90% dos pacientes, situação em que essa obstrução é investigada pelo ultrassom intravascular. Métodos diagnósticos menos invasivos, como o Doppler vascular, ou mesmo invasivos, como a flebografia, podem falhar em seu diagnóstico. O tratamento endovascular dessas obstruções tem se demonstrado eficaz, seguro e associado a excelente resultado clínico e de perviedade, desde que princípios anatômicos e técnicos fundamentais sejam considerados e aplicados.
