Headaches during angiography and endovascular procedures.

Research output: Contribution to journalArticlepeer-review

Abstract

BackgroundThe occurrence of headaches during cerebral angiography or endovascular procedures is an ill-defined issue, as limited information is available to define its frequency, risk factors, pathogenesis and implications for future pain management.PurposeTo determine the frequency of headaches during endovascular procedures (HdEVP) and to define their characteristics and risk factors for their occurrence.MethodsProspective cross-sectional observational study of adult patients undertaking cerebral angiography or endovascular procedures, recording HdEVP clinical features, previous headache history and procedural variables.ResultsOne hundred and twenty two procedures were evaluated. HdEVP occurred in 13 patients, both in diagnostic and therapeutic procedures. Pain was described as brief, stabbing or localized pressure of mild to moderate intensity, felt ipsilaterally to the manipulated vessel. Its occurrence was associated with therapeutic interventions (p = 0.007), female gender (p = 0.015) and previous history of more than 4 headache episodes per month (p = 0.018).ConclusionHdEVP is an uncommon brief headache that should be further evaluated in the future. Its pathogenesis is probably related to mechanical vessel distension, which activates the trigeminovascular nociceptive system in susceptible individuals.
