Endovascular Interventions of Cancer-Associated Venous Thromboembolism with Symptomatic Iliocaval Venous Thrombosis: A Case Report

Abstract

Cancer-associated venous thromboembolism (CAT) poses a severe threat, disrupting ongoing cancer management and adversely impacting treatment outcomes. CAT often leads to a two- to six-fold increase in mortality rates when it progresses to venous total occlusion. The primary modalities employed in addressing this life-threatening complication include anticoagulant therapy only or coupled with strategic endovascular interventions. Aggressive endovascular interventions, such as mechanical thrombectomy and venous stent implantation, are crucial in mitigating thrombotic complications, relieving symptoms, and improving this vulnerable population’s overall quality of life and life expectancy. This case report presents a CAT case extending to the total occlusion of the inferior vena cava. Our goal is to provide valuable insights into the evolving management of CAT and its sequelae, showcasing treatment approaches that lead to improved outcomes and a better quality of life for cancer patients facing these additional challenges.
