What is a significant risk associated with pulmonary angiography?

In the context of pulmonary angiography, the significant risk associated with the procedure is the potential for contrast-induced nephropathy. This condition arises when contrast media used during imaging studies affects renal function, leading to a deterioration in kidney health. Patients, especially those with pre-existing kidney issues or dehydration, are at a higher risk of experiencing complications related to contrast agents, which can result in increased creatinine levels or acute kidney injury.

Monitoring renal function prior to and following the procedure is crucial for identifying patients who might be at risk. Adequate hydration and utilizing low-osmolar contrast agents can often help mitigate this risk, but it remains a serious concern that healthcare providers must address in the planning and execution of pulmonary angiography.

While decreased oxygen saturation, allergic reactions to sedatives, and pneumothorax can also represent risks in various procedural contexts, they are not as directly linked to the specific nature of pulmonary angiography and its dependence on contrast media. The risk of contrast-induced nephropathy specifically highlights the implications of the contrast agents used during the procedure, making it the most significant risk factor in this scenario.
