Carotid pain during percutaneous angioplasty (PTA). Pathophysiology and clinical features.
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.
