Insights
Headache following carotid artery stenting is common, typically mild, short-lived, and often unilateral. Age was the only significant factor associated with its occurrence in this study.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Cardiology
Background:
- Headache is a potential post-procedural symptom following carotid artery stenting (CAS).
- Understanding its characteristics is crucial for patient management and differentiating it from procedural complications.
Purpose of the Study:
- To describe the clinical features of headaches occurring after carotid artery stenting.
- To identify potential associated risk factors.
Main Methods:
- Prospective observational study involving 56 patients undergoing CAS.
- Data collected via structured interviews pre-procedure and 24 hours post-procedure.
- Included sociodemographics, cardiovascular risk factors, and headache history.
Main Results:
- Headache occurred in 21.4% of patients, predominantly in men (83.3%).
- Headaches were typically unilateral, oppressive, mild to moderate in intensity, and short-lasting.
- Onset occurred within 6 hours post-procedure in most cases; age was significantly associated (P=.007).
Conclusions:
- Headache post-CAS in this cohort was generally mild and transient.
- Further research is needed to fully elucidate characteristics and risk factors.
Introduction And Objectives:
Headache after carotid artery stenting is a headache with onset during the procedure or in the first few hours after it, and where there is no evidence to suggest a complication of that procedure. The purpose of this study is to describe the main features of these headaches based on our clinical experience.
Patients And Methods:
Observational prospective study of a sample of patients undergoing carotid artery stenting at Hospital Clínico Universitario Lozano Blesa, in Zaragoza, Spain. We recorded sociodemographic characteristics, cardiovascular risk factors, carotid artery disease, and history of primary headache; data were gathered using structured interviews completed before and 24hours after the procedure.
Results:
We included 56 patients (mean age 67±9.52 years); 84% were men. Twelve patients (21.4%) experienced headache, 83.3% of whom were men; mean age was 60.58±9.31 years. Headache appeared within the first 6hours in 7 patients (58.4%) and during the procedure in 4 (33.3%). Pain lasted less than 10minutes in 4 patients (33.3%) and between 10 and 120minutes in 5 (41.7%). Headache affected the frontotemporal area in 7 patients (58.3%); 7 patients (58.3%) described pain as unilateral. It was oppressive in 8 patients (66.7%) and of moderate intensity in 6 (50%). Nine patients (75%) required no analgesics. We found no statistically significant associations with any of the variables except for age (P=.007; t test).
Conclusions:
In our sample, headache after carotid artery stenting was mild to moderate in intensity, unilateral, oppressive, and short-lasting. Further studies are necessary to gain a deeper knowledge of its characteristics and associated risk factors.
