Playing a more vital role in the field of medicine than ever before, embolotherapy is a type of endovascular treatment that aims to occlude abnormal blood vessels in order to control bleeding, close fistulae or arteriovenous malformations, devascularise organs, reduce tumours and much more. To accomplish occlusion, embolotherapy uses minimally-invasive techniques and various embolic agents, such as gelfoam, coils, balloons and angiographic catheters to achieve precise and significant results. The embolic agents used can be either temporary or permanent and are determined according to the clinical application, and thus can vary greatly from case to case.
Embolotherapies have become mainstays of interventional radiology practice. In order to perform embolotherapy correctly, IRs must be experienced, up-to-date on the latest data, familiar with underlying pathologies and knowledgeable on how other specialities can also contribute to patient treatment.
As the field covers such a wide range of treatment possibilities, from recognised therapies such as TACE, UFE and venous embolisation, to some of the less commonly known applications such as haemorrhoid and arthritis embolisation, it continues to advance in order to become more precise, more evidence-based and even more impactful in the years to come.
