Which of the following is most likely to be an absolute contraindication for hepatic artery interventions?

In the context of hepatic artery interventions, an unstable patient represents a critical contraindication due to the risks associated with performing invasive procedures on individuals whose physiological status is compromised. An unstable patient may exhibit significant hemodynamic instability, resulting in an inability to tolerate the stress of an interventional procedure. This could lead to severe complications such as further cardiovascular instability, hemorrhage, or even cardiac arrest during the procedure.

While uncontrolled coagulopathy and prior allergic reactions to iodinated contrast material are substantial concerns that can affect the safety and outcome of interventions, they may often be managed through medical interventions prior to or during the procedure. Renal insufficiency poses risks as well, particularly concerning contrast nephropathy, but with proper patient management strategies, interventions can be safely executed.

On the other hand, if a patient is unstable, the potential for immediate life-threatening events during the procedure outweighs any scheduled or planned intervention. Thus, ensuring the patient’s stability is paramount before considering any type of invasive procedure, making the state of being unstable an absolute contraindication for hepatic artery interventions.
