What complication is associated with neuro angiography?

Thromboembolism is a known complication associated with neuroangiography primarily due to the manipulation of vascular structures during the procedure. During neuroangiography, catheters are advanced through the vascular system to access arterial networks in the brain. This process can dislodge atherosclerotic plaques or thrombi from the vessel wall, potentially leading to obstruction of distal arteries with emboli. This complication can result in ischemic strokes, which are often serious and can have lasting effects on the patient.

Understanding the risk of thromboembolism is crucial in the context of neuroangiography, as it underscores the importance of patient selection, procedural technique, and the use of preventive measures such as adequate anticoagulation strategies during the procedure. Monitoring patients closely for neurological deficits after the procedure is vital for early detection and management of any complications that may arise from thromboembolic events.

The other options listed, while certainly important concerns in various medical contexts, are not typically associated with neuroangiography in the same manner. For instance, pneumothorax is more commonly linked to thoracic procedures, cardiac arrest can occur in a variety of contexts but is not specific to neuroangiography, and severe hypertension may be a result of stress or pain during
