Abstract
Stretching of the internal carotid artery during percutaneous transluminal angioplasty (PTA) may be associated with transient neck, facial or cranial pain. We report a series of 53 cases who received PTA. Cervical pain occurred in 51% of patients, with a radiation to face and scalp in 33%. Analysis focused on: (a) description of pain intensity, quality, timing and location; (b) investigation about the role of individual and technical parameters that could influence the relative risk of pain onset during PTA; (c) comparison with other available data on pain syndromes related to the carotid artery. Intimal flapping on post-angioplasty angiograms, bradycardia during the procedure and previous history of AMI were associated with a higher risk of painful angioplasty. PTA may also serve as a tool to investigate carotid pain and may add further knowledge to the evidence available about the role of the carotid wall in the pathogenesis of facial and cranial pain.
