Vascular embolization or occlusion, inclusive of all radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance necessary to complete the intervention; for tumors, organ ischemia, or infarction

Vascular embolization or occlusion is a medical procedure aimed at obstructing blood flow to specific areas within the body, particularly for the treatment of tumors, organ ischemia, or infarction. This intervention is crucial in managing conditions where blood supply to a tumor or an organ needs to be reduced or eliminated to prevent further complications or to facilitate treatment. The procedure begins with the acquisition of initial angiograms, which are imaging studies that help identify the blood vessels supplying the tumor or affected organ. This imaging is essential for the physician to determine the most appropriate vascular access site for the embolization or occlusion. The process involves a series of carefully executed steps, including the insertion of an introducer sheath into the selected blood vessel, followed by the advancement of a guide wire and catheter to the targeted site. Once the catheter is in place, additional angiography is performed to visualize the vasculature and confirm the location of the tumor or organ. The introduction of occlusive or embolic materials, such as viscous collagen agents, polyvinyl alcohol particles, or ethiodized oil, is then carried out to effectively block the blood supply. After the embolic material is deployed, further angiograms are conducted to verify that the targeted blood vessel has been completely occluded. The procedure may involve multiple feeding vessels, ensuring comprehensive treatment. Finally, the catheter is removed, and pressure is applied to the vascular access site to manage any potential bleeding, marking the conclusion of the intervention.
